It is a 2nd figure which shows the example of a display of a panoramic image. It is a 3rd figure which shows the example of a display of a panoramic image. It is a figure which shows the example of a display of the panoramic image in a list display.

  FIG. 1 is a block diagram showing a configuration of an embodiment of a digital still camera (DSC) in the present embodiment. A digital still camera (hereinafter referred to as “digital camera”) 100 includes a lens 101, a CCD 102, an image processing circuit 103, a display controller 104, an LCD panel 105, a CPU 106, an SDRAM 107, a JPEG codec 108, and a USB. A controller 109 and a memory card controller 110 are provided.

  The CPU 106 is a main controller that controls the entire digital camera 100, and controls the digital camera 100 by executing shooting processing, image reproduction processing, image data transfer processing, and the like.

  First, photographing processing in the digital camera 100 will be described. An optical image of a subject input through the lens 101 is photoelectrically converted and read by a CCD 102 that is an image sensor, and then converted into digital image data (RAW data) by an AFE (Analog Front End) (not shown). Input to the image processing circuit 103. The image processing circuit 103 performs various image processing on the input digital image data, and records the image data after the image processing in the SDRAM 107. The image processing circuit 103 performs calculation and control of 3A (AE, AF, AWB) at the time of shooting.

  The SDRAM 107 is a volatile built-in memory, and is used as a buffer memory for temporarily recording image data. The CPU 106 develops a program when the program is executed, and stores variables used in the program. Or used as work memory.

  The JPEG codec 108 reads out the image data recorded in the SDRAM 107, compresses the image data using JPEG, and records the image data in the SDRAM 107 again. The CPU 106 reads out JPEG-compressed image data (JPEG data) from the SDRAM 107 and generates an image file (JPEG file) in which various additional information (metadata) is added to the JPEG data. Then, when the CPU 106 sends the generated JPEG file to the memory card controller 110, the memory card controller 110 records the JPEG file on the memory card 110a inserted in the memory card slot. This completes the photographing process.

  At the time of shooting, the LCD panel 105 mounted on the back of the camera functions as an LCD finder, and image data after image processing by the image processing circuit 103 is displayed on the LCD panel 105 at predetermined frame intervals. The photographer determines the composition while confirming the display on the LCD panel 105.

  Next, image data reproduction processing in the digital camera 100 will be described. The CPU 106 controls the memory card controller 110 to read a JPEG file from the memory card 110a. The CPU 106 reads out the JPEG data from the read JPEG file, decompresses it, and outputs it to the image processing circuit 103. The image processing circuit 103 performs resolution conversion on the input decompressed data, generates display image data by changing the resolution of the image according to the display resolution of the LCD panel 105, and records it in the SDRAM 107. To do.

  The display controller 104 reads display image data from the SDRAM 107 and displays it on the LCD panel 105.

  In the digital camera 100 according to the present embodiment, in addition to the JPEG file generated by the normal photographing process described above, that is, an image file in which one JPEG data is recorded in one image file, a plurality of images are included in one image file. An image file in which the JPEG data is recorded can also be generated. For example, when the continuous shooting is performed, the panorama shooting is performed, or the interval shooting is performed, the CPU 106 generates a set of a plurality of JPEG data by one shooting. Stores a plurality of generated JPEG data in one image file. That is, the CPU 106 generates an image file that records a plurality of JPEG data.

  In the present embodiment, an image file in which one image data is recorded in one image file is called an SP file (SinglePicture file / single image file), and an image file in which a plurality of image data is recorded in one image file. Are called MP files (MultiPicture files / multiple image files). The SP file includes a main image that is main recording data and a thumbnail that is generated from the main image and used for display and search. On the other hand, the MP file is generated from the main image in addition to the main image, and includes a monitor display image used exclusively for monitor display, a thumbnail generated from the main image, and the like. Can be recorded. In the present embodiment, a case where image data is recorded as JPEG data will be described, and the JPEG data of the main image and the monitor display image in the MP file will be referred to as individual images in accordance with the MP format standard. Further, as the format of the SP file, a known Exif standard (Exchangeable image file format for digital still cameras) is used. Thumbnails of both SP files and MP files are embedded in JPEG data (APP1) of the main image.

  In the present embodiment, when an instruction to reproduce an image is given by the user, the CPU 106 reads the image data of the main image, the monitor display image, or the thumbnail from the image file to be reproduced, and controls the display controller 104. Then, an image is displayed on the LCD panel 105. At this time, when the image file to be reproduced is an MP file including a plurality of image data obtained by panoramic shooting, the CPU 106 combines the plurality of image data in the image file to generate a panorama image, The panoramic image is displayed on the LCD panel 105.

  Whether the MP file is obtained by panoramic shooting can be determined by the MP type recorded in the header portion (MP index information) of the MP file. In addition, a panorama image arrangement tag and an overlap region tag, which are information necessary for generating a panorama image based on a plurality of image data in the MPF file, are recorded as MP individual information in the header portion. If the MP file is obtained by panoramic shooting based on the MP type read from the header portion of the MP file to be reproduced, the CPU 106 sets the panorama image arrangement tag and the overlap region tag from the header portion. And stitching the images based on these to generate a panoramic image.

  The panorama image arrangement tag is used to specify how many rows and columns of images are arranged as information for specifying how to arrange a plurality of image data in the MP file to generate a panorama image. Where is the position of the image to be placed (four types, upper right, upper left, lower left, lower right), how to place other images according to the position of the first placed image (start position), etc. Contains information for identifying. Examples of the image arrangement method include one direction, clockwise rotation, counterclockwise rotation, and zigzag. In addition, the overlap region tag is used as information for specifying a range in which adjacent images overlap when generating a panoramic image, and a horizontal overlap and a vertical direction for specifying a horizontal overlap width are specified. Vertical overlap for specifying the overlap width.

  For example, when the photographer intends to take a panoramic photograph as shown in FIG. 2A, the images 2a, 2b, 2c, and 2d are displayed as shown in FIG. Four images are taken and these four image data are recorded in the MP file. When reproducing the MP file, the CPU 106 arranges the images 2a to 2d based on the panorama image arrangement tag recorded in the header portion as shown in FIG. Based on the above, the overlap width of each image is specified. In the example shown in FIG. 2C, images are arranged in one horizontal row, and the horizontal overlap width of each image is 30% of the horizontal width of the image.

  As shown in FIG. 2D, the CPU 106 cuts the overlap area from any one of the adjacent images in the object field so that the overlap areas of the images do not overlap, and then FIG. As shown in FIG. 5, each image is stitched to generate a panoramic image 2 e. In the example shown in FIG. 2D, the image 2a is not cut, and the left overlap region is cut from each of the images 2b to 2d. The CPU 106 displays the panoramic image 2e generated by Stitching on the LCD panel 105. As a result, when playing back an MP file obtained by panoramic shooting, the image can be displayed like a panoramic image.

  In the present embodiment, the CPU 106 determines whether image data to be subjected to Stitching uses main image data, monitor display image data, or thumbnail data. 105 or an external monitor (television) (not shown) or the like. For example, when the screen size of the LCD panel 105 is close to the size of the panorama image obtained by performing the stitching using the monitor display image data, the panorama image is generated using the monitor display image data. On the other hand, when the screen size of the LCD panel 105 is close to the size of the panoramic image obtained by performing the stitching using the thumbnail data, the panoramic image is generated using the thumbnail data. If the image display device is a full HD television monitor, the stitching may be performed using image data of either the main image or the monitor display image.

  The image reproduction process in this embodiment will be described with reference to FIG. The processing shown in FIG. 3 is executed by the CPU 106 as a program that is activated when an instruction to reproduce an image is given by the user. FIG. 3 shows processing when one MP file is designated as a reproduction target from among image files recorded on the memory card 110a by the user.

  In step S10, the CPU 106 reads the MP type from the header portion (MP index information) of the MP file designated as the reproduction target by the user. Thereafter, the process proceeds to step S20, and the CPU 106 determines whether the MP file to be reproduced is an image file obtained by panoramic shooting based on the MP type. If a negative determination is made in step S20, the process proceeds to step S30, and the CPU 106 displays an image corresponding to the MP type of the image file. For example, image data recorded in an MP file is displayed frame by frame. Thereafter, the process ends.

  On the other hand, if a positive determination is made in step S20, the process proceeds to step S40. In step S40, the CPU 106 reads the MP individual information described above from the header portion of the MP file, and proceeds to step S50. In step S50, the CPU 106 determines whether or not the above-described panoramic image arrangement tag is included in the MP individual information. If it is determined in step S50 that the panoramic image placement tag is included, the process proceeds to step S60.

  In step S60, the CPU 106 determines whether or not the above-described overlap region tag is included in the MP individual information. If it is determined in step S60 that the overlap area tag is included, the process proceeds to step S70. In step S70, as described above, the CPU 106 selects one of main image data, monitor display image data, and thumbnail data as image data used for generating a panoramic image according to the screen size of the LCD panel 105. Select.

  Thereafter, the process proceeds to step S80, and the CPU 106 reproduces (decodes) the main image, monitor display image, or thumbnail data selected in step S70, and then proceeds to step S90. In step S90, as described above with reference to FIG. 2, the CPU 106 overlaps from any one of the adjacent images in the scene so that the overlap regions of the images do not overlap based on the overlap region tag. Cut off the area. Thereafter, the process proceeds to step S100, and the CPU 106 arranges and stitches each image based on the panorama image arrangement tag to generate a panoramic image as described above with reference to FIG. Then, it progresses to step S110.

  In step S110, CPU 106 outputs and displays the panoramic image generated in step S100 on LCD panel 105, and ends the process. At this time, if the size of the generated panorama image and the screen size of the LCD panel 105 are different, the CPU 106 may adjust the size of the panorama image according to the screen size of the LCD panel 105 and display it. It may be displayed in the same size. Which method is used for display may be selected by the user on the menu screen.

  When the panorama image is displayed as it is, there is no problem if the panorama image is smaller than the screen size of the LCD panel 105, and the entire panorama image is displayed. If the screen size is larger than 105, the entire panoramic image cannot be displayed. In this case, the user can operate an operation member (not shown) to scroll the image. For example, as shown in FIG. 4, when the panorama image 4b is displayed on the display screen 4a of the LCD panel 105, the region 4c of the panorama image 4b protrudes from the display screen 4a. In this case, the user can also display the region 4c by scrolling the panoramic image 4b in the horizontal direction. The example shown in FIG. 4 shows an example in which the panoramic image 4b protrudes in the horizontal direction with respect to the display screen 4a of the LCD panel 105, but it is also possible that the panoramic image 4b protrudes in the vertical direction. By scrolling to, the protruding portion of the panoramic image can be displayed.

  Next, a process when it is determined in step S60 that the MP individual information does not include an overlap area tag will be described. In this case, since the CPU 106 cannot specify the overlap area, it cannot cut the overlap area of each image. Therefore, as shown in FIG. 5, the CPU 106 displays one of a plurality of individual images 2a to 2d included in the MP file, for example, an individual image 2a (main image or monitor) on the display screen 5a of the LCD panel 105. Display image) is displayed, and a panorama layout 5b in which thumbnails 5c to 5f corresponding to the individual images 2a to 2d are arranged based on the panorama image arrangement tag is displayed. Then, the CPU 106 displays the thumbnail 5c corresponding to the individual image 2a displayed in the display screen 5a among the thumbnails in the displayed panorama layout 5b in a display form different from the other thumbnails. For example, the thumbnail 5c in the panorama layout 5b is surrounded by a frame and displayed.

  That is, if it is determined in step S60 that the MP individual information does not include an overlap area tag, the process proceeds to step S120, and the CPU 106 stores the thumbnail data recorded as a set with each main image in the MP file. Is read and reproduced (decoded). Thereafter, the process proceeds to step S130, and the CPU 106 arranges the thumbnails 5c to 5f based on the panorama image arrangement tag, and creates the panorama layout 5b. Thereafter, the process proceeds to step S140, and the CPU 106 displays the created panorama layout 5b on the upper layer of the LCD panel 105.

  Thereafter, the process proceeds to step S150, and the CPU 106 reads out and reproduces (decodes) one of the individual images 2a to 2d, for example, image data (main image or monitor display image) of the individual image 2a from the MP file. Then, the process proceeds to step S160. In step S160, the CPU 106 displays the decoded individual image 2a on the lower layer of the LCD panel 105. Thereafter, the process ends.

  Next, processing when it is determined in step S50 that the MP individual information does not include a panoramic image arrangement tag will be described. In this case, the CPU 106 cannot specify the arrangement method of each individual image. Therefore, as shown in FIG. 6, the CPU 106 displays one of a plurality of individual images 2a to 2d included in the MP file, for example, an individual image (main image or monitor display) on the display screen 6a of the LCD panel 105. Image) 2a is displayed, and a panorama layout 6b in which thumbnails 6c to 6f corresponding to the individual images 2a to 2d are arranged by a preset arrangement method is displayed. For example, the CPU 106 creates and displays a panorama layout 6b in which thumbnails 6c to 6f corresponding to individual images recorded in the MP file are arranged in a horizontal row in the order of individual image numbers recorded as header information. . Then, the CPU 106 displays the thumbnail 6c corresponding to the individual image 2a displayed in the display screen 6a among the thumbnails in the displayed panorama layout 6b in a display form different from the other thumbnails. For example, the thumbnail 6c in the panorama layout 6b is displayed surrounded by a frame.

  That is, if it is determined in step S50 that the panoramic image placement tag is not included in the MP individual information, the process proceeds to step S170, and the CPU 106 stores the thumbnail data recorded as a set with each main image in the MP file. Is read and reproduced (decoded). Thereafter, the process proceeds to step S180, and the CPU 106 arranges the thumbnails 6c to 6f by a preset arrangement method, and creates a panorama layout 6b. Then, it progresses to step S140 mentioned above.

  As shown in FIGS. 5 and 6, when displaying the panorama layout 5b or 6b superimposed on one individual image in the MP file, the user is selected in the panorama layout 5b or 6b. Individual images to be displayed in the display screen 5a or 6a may be switched by selecting a thumbnail that is different from the thumbnail that is displayed (enclosed by a frame). In this case, when the user selects a thumbnail different from the thumbnail surrounded by the frame in the panorama layout 5b or 6b, the CPU 106 surrounds the newly selected thumbnail with the frame and newly The individual image corresponding to the selected thumbnail may be decoded and displayed on the lower layer of the LCD panel 105.

  As shown in FIGS. 5 and 6, when the panorama layout 5b or 6b is displayed superimposed on one individual image in the MP file, the individual image 2a displayed in the display screen 5a or 6a is displayed. Since a part is hidden by the panorama layout 5b or 6b, the user may arbitrarily delete the display of the panorama layout 5b or 6b. In this case, when the user instructs to delete the panorama layout 5b or 6b, the CPU 106 stops displaying the panorama layout 5b or 6b on the upper layer of the LCD panel 105, and the individual image is displayed on the display screen 5a. Only 2a is displayed.

  The user can also instruct redisplay of the panorama layout 5b or 6b after erasing the panorama layout 5b or 6b, and the CPU 106 is instructed to redisplay the panorama layout 5b or 6b. In this case, the display of the panorama layout 5b or 6b on the upper layer of the LCD panel 105 is resumed.

According to the present embodiment described above, the following operational effects can be obtained.
(1) Based on the panorama image arrangement tag in the MP file, the CPU 106 specifies the arrangement position of the plurality of individual images in the scene, and based on the overlap area tag, the CPU 106 determines the adjacent images in the scene. A panoramic image is generated by cutting the overlap area from either one and then performing stitching, and the generated panoramic image is displayed on the LCD panel 105. As a result, when playing back an MP file obtained by panoramic shooting, the image can be displayed like a panoramic image.

(2) In the MP file, thumbnails used for display and search are recorded together with the main image, and the CPU 106 determines that the combined panoramic image size of the main image and the thumbnail is the screen size of the LCD panel 105. A panoramic image was generated for one of the nearby objects. Thereby, a panoramic image having a size corresponding to the screen size of the LCD panel 105 can be generated.

(3) When the panorama image size is larger than the screen size of the LCD panel 105 and the entire panorama image cannot be displayed on the screen, the CPU 106 scrolls and displays the panorama image according to an instruction from the user. I tried to do it. Accordingly, even when the size of the panoramic image is larger than the screen size of the LCD panel 105, the user can view the entire panoramic image.

(4) When the panorama image arrangement tag is recorded in the MP individual information and the overlap area tag is not recorded, the CPU 106 arranges each thumbnail and creates a panorama layout based on the panorama image arrangement tag. The created panorama layout is displayed on the upper layer of the LCD panel 105, and the individual image (main image or monitor display image) corresponding to the thumbnail selected on the panorama layout is displayed on the lower layer of the LCD panel 105. did. Thereby, the user can confirm the panorama layout together with the individual images.

(5) When neither the panorama image arrangement tag nor the overlap area tag is recorded in the MP individual information, the CPU 106 creates a panorama layout by arranging each thumbnail by a preset arrangement method. The panorama layout is displayed on the upper layer of the LCD panel 105, and an individual image (main image or monitor display image) corresponding to the thumbnail selected on the panorama layout is displayed on the lower layer of the LCD panel 105. Thereby, the user can confirm the panorama layout together with the individual images.

(6) When the thumbnail selected in the panorama layout displayed on the upper layer of the LCD panel 105 is changed, the CPU 106 selects an individual image (main image or monitor) corresponding to the newly selected thumbnail. The display image) is displayed on the lower layer of the LCD panel 105. Accordingly, the user can display an individual image corresponding to the selected image on the lower layer by selecting an image on the panorama layout.

(7) The CPU 106 erases the display of the panorama layout displayed on the upper layer of the LCD panel 105 based on an instruction from the user. Accordingly, the user can erase the panorama layout and browse the entire individual image in the lower layer.

-Modification-
The camera according to the above-described embodiment can be modified as follows.
(1) In the embodiment described above, when the screen size of the LCD panel 105 is close to the size of the panoramic image obtained by performing the stitching using the thumbnail data, the CPU 106 uses the thumbnail data. An example of generating an image has been described. However, when a monitor display image is recorded in the MP file, if the screen size of the LCD panel 105 is close to the size of the panoramic image obtained by performing Stitching using the monitor display image data, A panoramic image may be generated using data of a monitor display image. For example, the above-mentioned thumbnail has an image size of 180 × 120 pixels, but the MP file has a larger VGA size (640 × 480 pixels) or Full HD size (1920 × 1080 pixels) monitor. A display image can be recorded. Therefore, when these monitor display images are recorded in the MP file, the CPU 106 may generate a panoramic image using these image data. Note that if a VGA size or Full HD size monitor display image is recorded in the MP file, the CPU 106 refers to the header portion because information indicating that fact is recorded in the header portion. It may be determined whether or not a monitor display image is recorded in the MP file.

(2) In the above-described embodiment, the CPU 106 has a case where the screen size of the LCD panel 105 is close to the size of the panoramic image obtained by performing Stitching using the data of the individual image (main image or monitor display image). When the panorama image is generated using the individual image data and the screen size of the LCD panel 105 is close to the size of the panorama image obtained by performing the stitching using the thumbnail data, the thumbnail data is An example in which a panoramic image is generated using the above has been described. However, when display image data such as a thumbnail or the above-mentioned monitor display image is recorded in the MP file, the CPU 106 uses these display image data regardless of the screen size of the LCD panel 105. Thus, a panoramic image may be generated.

(3) In the above-described embodiment, the CPU 106 has described an example in which whether to use individual image data or thumbnail data as image data to be stitched is determined according to the screen size of the LCD panel 105. . In this case, after determining whether to use individual image data or thumbnail data as the image data to be stitched according to the screen size of the LCD panel 105, the CPU 106 performs stitching using the determined image data. The size of the panorama image may be compared with the screen size of the LCD panel 105. Further, instead of actually performing Stitching, an image size after Stitching may be obtained by calculation and the screen size of the LCD panel 105 may be compared. As a result, if the difference between the size of the panoramic image and the screen size of the LCD panel 105 differs by a predetermined multiple or more, the size of the image before Stitching is changed according to the screen size of the LCD panel 105 and then Stitching is performed. A panoramic image may be generated in a row. As a result, when the panoramic image size and the screen size of the LCD panel 105 are significantly different, the optimal size corresponding to the screen size of the LCD panel 105 is adjusted in advance by adjusting the size of the image before Stitching. A panoramic image can be generated.

(4) In the above-described embodiment, the CPU 106 has described an example in which one panoramic image is displayed on one screen as shown in FIG. However, as shown in FIG. 7, the CPU 104 displays a list of a plurality of images within one screen, and when there are MP file images, a plurality of images such as images 7 a and 7 b are displayed. May be displayed so as to indicate that the image is an image in the MP file. When the CPU 106 determines that the MP file is obtained by panoramic shooting based on the MP type of the MP file when the user moves the cursor to the image of the MP file. Alternatively, another window may be displayed on the LCD panel 105, and a panoramic image subjected to stitching for thumbnail data may be displayed in the other window.

(5) In the above-described embodiment, the CPU 106 reads the overlap area tag from the header portion of the MP file, and specifies the overlap width of each image based on the overlap area tag, thereby adjacent images. The example which specifies the area | region (overlap area | region) which overlaps between was demonstrated. However, the CPU 106 identifies the overlap region of each image based on the overlap region tag, and performs pixel matching between adjacent images in the identified overlap region or a region including the vicinity thereof. You may make it pinpoint the range which overlaps between both images correctly. Or you may make it specify correctly the range which has overlapped between both images by matching for all the pixels of adjacent images.

(6) In the embodiment described above, in the example shown in FIG. 6, the CPU 106 includes a plurality of individual images 2a to 2d (main image or monitor) included in the MP file in the display screen 6a of the LCD panel 105. Display image), for example, an individual image 2a, and a panorama layout 6b in which thumbnails 6c to 6f corresponding to the individual images 2a to 2d are arranged by a predetermined arrangement method are displayed. I tried to do it. In this case, the user may arbitrarily change the display order (arrangement order) of the thumbnails 6c to 6f displayed in the panorama layout 6b.

(7) In the above-described embodiment, the example in which a plurality of image data acquired by panoramic shooting is recorded in one MP file has been described. However, the present invention can also be applied to a case where a plurality of image data acquired by panoramic shooting is recorded separately in a plurality of image files.

(8) In the above-described embodiment, the monitor display image and the thumbnail are generated from the main image. However, the monitor display image and the thumbnail are generated from the RAW data from which the main image is generated. Also good. Alternatively, the monitor display image may be generated from the RAW data or the main image, and the generated monitor display image may be reduced to generate a thumbnail.

  Note that the present invention is not limited to the configurations in the above-described embodiments as long as the characteristic functions of the present invention are not impaired. Moreover, it is good also as a structure which combined the above-mentioned embodiment and a some modification.
