Description

  The present invention relates to an imaging apparatus and an imaging method that enable zoom photography in macro photography suitable for application to a digital camera, for example.

  An electronic camera device such as a digital camera has a so-called macro shooting mode that enables close-up shooting and a zoom shooting mode that enables a zoom operation from the wide end (W) to the tele end (T). In such a digital camera, an image of a subject captured in the macro photographing mode and the zoom photographing mode is subjected to photoelectric conversion, signal conversion, signal processing, and the like by an image pickup device such as a CCD (Charge Coupled Device), and then the subject is displayed on the display device. Displayed as a monitor image (so-called through image). When the user presses the shutter at a desired timing while looking at the monitor image, shooting is performed, and the shot image of the subject after signal processing is recorded and stored in a storage medium as recorded image data. In addition, information of a recorded image recorded on and stored in a recording medium can be read and reproduced on a display device such as a liquid crystal display for display or output to an external device.

  In such a digital camera, normally, a zoom position indicator indicating the position of the zoom lens from the wide end (W) to the tele end (T) in the zoom photographing mode as shown in FIG. 9 together with the monitor image displayed on the display device. 91 and a macro shooting icon indicating the macro shooting mode are displayed on the display device as an image. However, in the zoom position mark movable range 92 indicated by the zoom position indicator 91, the range from 1/3 of the wide end (W) to the tele end (T) is a focus range 93 during macro shooting.

  Here, if the zoom lens is moved from the wide end (W) to the tele end (T), the light amount is insufficient and the lens aberration is poor in the wide-angle region. However, a zoom lens macro mechanism is disclosed in which the restriction member for this purpose is movable, and the restriction member is moved within the focal length range allowed for lens performance to release the restriction of the photographing distance range (for example, , See Patent Document 1).

Also disclosed is a light emitting device that minimizes the switching operation for adjusting the light emission amount of a strobe to a subject at a close distance in a macro shooting mode of a digital camera equipped with an autofocus function, and a control method thereof ( For example, see Patent Document 2.)
Japanese Patent Publication No.57-66425 JP 11-126695 A

  For this reason, in the conventional digital camera, the entire range from the zoom lens wide end (W) to the telephoto end (T) can be moved in the macro shooting mode. The position of the lens is more easily set on the telephoto end (T) side than on the wide end (W). At this time, when deciding the angle of view of the subject that is almost the same size as when the zoom lens position is set to the wide end (W) side, the zoom lens is enlarged by the zoom lens away from the subject. A reduction in the sharpness of the image during autofocus has a disadvantage that the out-of-focus range 93 during macro shooting occurs in the zoom position mark movable range 92 indicated by the zoom position indicator 91.

  Further, in the macro mechanism of the zoom lens disclosed in Patent Document 1, as described above, the limiting member and the release mechanism thereof must be provided in the zoom lens, and the mechanism of the zoom lens becomes complicated. There is a disadvantage that it is difficult to apply to a digital camera having an autofocus function.

  Further, in the zoom lens macro mechanism disclosed in Patent Document 1, the movable range of the zoom lens in the macro shooting mode cannot be displayed on the display unit, and thus the user cannot recognize the movable range. There was an inconvenience that it was bad.

  In addition, the light emitting device and the control method thereof disclosed in Patent Document 2 have been described for a macro shooting mode of a digital camera having an autofocus function. Not disclosed.

  Therefore, the present invention controls the zoom lens by limiting the movement position of the zoom lens so that it is in focus during autofocus, and displays the movable range of the zoom lens on the display unit corresponding to the zoom lens restriction range. Thus, an object of the present invention is to provide an imaging apparatus and an imaging method capable of improving the operability by optimizing the zoom operation in the macro imaging mode.

  In order to solve the above-described problems and achieve the object of the present invention, the imaging apparatus of the present invention is based on selection means for enabling selection of a close-up shooting mode and a zoom shooting mode, and selection of the close-up shooting mode and the zoom shooting mode. Driving means for driving the optical lens in the optical axis direction, and a limited range in which the focus control is in focus for driving the optical lens through the driving means when the close-up shooting mode and the zoom shooting mode are selected. And a control means for controlling to limit to, and a signal for displaying the driving range of the lens of the optical system on the display means when the close-up photography mode and the zoom photography mode are selected corresponding to the restriction range. Display signal generating means.

  In the present invention described above, when the close-up shooting mode and the zoom shooting mode are selected by the selection unit, the control unit limits the driving of the lens of the optical system via the driving unit to a limit range in which the focus control is in a focused state. To control. The drive means drives the lens of the optical system in the optical axis direction so as to limit the focus control to a limited range where the focus control is brought into focus based on the control by the control means at this time. At this time, the display signal generating means generates a signal for displaying the driving range of the lens of the optical system on the display means corresponding to the limited range. Thereby, the display means displays the driving range of the lens of the optical system corresponding to the limited range.

  Further, the imaging method of the present invention includes a step of selecting a close-up shooting mode and a zoom shooting mode, and focus control of driving of the lens of the optical system via a driving unit when the close-up shooting mode and the zoom shooting mode are selected. A step of controlling to limit to a limited range that is in focus, a step of driving the lens of the optical system in the optical axis direction based on the control of the close-up shooting mode and the zoom shooting mode, and the close-up shooting mode and the zoom shooting mode Generating a signal for displaying the driving range of the lens of the optical system corresponding to the limit range on the display means, and displaying the driving range of the lens of the optical system. It is.

  In the above-described present invention, when the close-up photographing mode and the zoom photographing mode are selected in the selection step, the control step restricts the driving of the lens of the optical system via the driving means to a limited range where the focus control is in a focused state. To control. In the driving step, the lens of the optical system is driven in the optical axis direction so as to limit the focus control to a limited range where the focus control is in a focused state based on the control by the control means at this time. At this time, in the display signal generation step, a signal for displaying the driving range of the lens of the optical system on the display means is generated corresponding to the limited range. Thereby, the display means displays the driving range of the lens of the optical system corresponding to the limited range.

  According to the present invention, the movement position of the zoom lens is limited and controlled so as to be in the focusing range during autofocus, and the movable range of the zoom lens is displayed on the display unit corresponding to the restriction range of the zoom lens. Thus, the zoom operation in the macro shooting mode can be made appropriate, and the operability can be improved.

Embodiments of the present invention will be described below with reference to the drawings as appropriate.
FIG. 1 is a block diagram showing a configuration as an example of an imaging apparatus according to an embodiment of the present invention. As shown in FIG. 1, the imaging apparatus is mainly composed of an optical system block and a control system block. The optical system block includes a photographing lens 1, an AF control unit 2 having an autofocus (AF) lens, a motor drive circuit 8 that drives a motor of the AF control unit 2, and a solid-state imaging device 3 such as a CCD. Yes.

  The control block includes a signal processing circuit 4, an internal memory 5, a display unit 6 such as a liquid crystal panel, a recording unit 7 that records captured data on a recording medium 9, and a macro shooting mode and a zoom shooting mode selection. A macro / zoom operation unit 11 that can be operated, a shutter key 13 that instructs to lock autofocus control by half-pressing and instructs a photographing operation by pressing deeply, and a CPU (Central Processing Unit) 10 that controls these. When the macro photographing mode and the zoom photographing mode are selected, the macro for controlling the driving of the photographing lens 1 via the motor driving circuit 8 so as to be limited to a restriction range in which the focus control of the AF control unit 2 is in an in-focus state. And an hour zoom control system 12.

  Normally, when the power switch is turned on, a power supply voltage is supplied from a power supply unit (not shown), and the display unit 6 that displays a monitor image enters a monitoring state. Then, the reflected light from the subject is focused by an autofocus lens (to be described later) through the photographing lens 1 and formed as an image on the light receiving surface of the solid-state image pickup device 3 such as a CCD. The image formed on the light receiving surface is converted into an amount of signal charge corresponding to the amount of reflected light forming the image, and displayed on the display unit 6 such as a liquid crystal panel.

  At this time, the data of the reflected light forming the incident image is temporarily stored in the internal memory 5, and the high frequency component of the stored data is supplied to the CPU 10. The CPU 10 sequentially controls the motor driving circuit 8 so that the autofocus lens is brought into focus by the AF control unit 2 based on the supplied data. This autofocus control is executed when the shutter key 13 is half-pressed.

  When the macro / zoom operation unit 11 selects and operates the macro shooting mode and the zoom shooting mode, the macro zoom control system 12 drives the shooting lens 1 via the motor drive circuit 8 to the AF control unit 2. The focus control is controlled so as to be limited to a limited range where the in-focus state is set.

  As a result, the zoom lens movement range is limited to a limit range in which the focus control of the AF control unit 2 is in focus when shooting while zooming in a state close to the subject in the macro shooting mode. In the macro shooting mode, the zoom operation can be controlled within the proper zoom lens movement range, and the proper zoom lens movement range described later is displayed on the display unit 6, so that only within the proper zoom lens movement range. The fact that zoom operation is possible is recognized by the user's vision, and operability can be improved.

  FIG. 2 shows a configuration example of the AF control unit. In FIG. 2, a captured image is photoelectrically converted by a solid-state imaging device 3 such as a CCD, and then a CDS (Correlated Double Sampling Circuit) 21, AGC (Automatic Gain Control) 22, and AD (Analog to Digital). ) Signal conversion processing is performed by the conversion unit 23. Thereafter, the signal processing unit 24 extracts a high frequency component of the image based on the detection range selection C <b> 1 from the CPU 10, and sends it to the AF detection circuit 25. The AF detection circuit 25 integrates this input high frequency component for one field period, and the CPU 10 supplies the control signal C2 to the motor drive circuit 8 so as to maximize this integration value, thereby moving the autofocus lens 27. The motor 26 is controlled.

  In the internal memory 5 shown in FIG. 1, the sharpness data of the monitor image at the time of the autofocus control is also temporarily stored. The monitor image is displayed on the display unit 6 even in this autofocus control state. When the shutter key 13 is half-pressed from this state and an instruction to lock the autofocus control is given, the image is relatively easily focused by the autofocus control method shown in FIG. At this time, sharpness data at the time of locking the half-press operation of the previous shutter key 13 is held. The monitor image in the locked state is also displayed on the display unit 6. After that, when the shutter key 13 is pressed deeply, the image data is captured and stored in the internal memory 5. This capture state is also displayed on the display unit 6 as a monitor image.

  The image sharpness data at the time of locking described above, that is, the sharpness data of the locked image is supplied to the CPU 10 to perform arithmetic processing. Then, the CPU 10 determines camera shake or out-of-focus based on the calculation processing result, and notifies the photographer on the recording medium 12 on the display unit 6 when there is a possibility that the out-of-focus is caused. An inquiry about whether to record is made.

FIG. 3 is a diagram showing the structure of the imaging lens (inner focus lens).
In FIG. 3, in this imaging lens, a variator (zoom lens) 32, a macro correction lens 33, and an autofocus lens 27 move in the optical axis direction in a cylindrical lens unit between the objective lens 31 and the CCD 3. Arranged to be possible. The variator (zoom lens) 32 performs a zoom operation for changing the focal length. As described above, the autofocus lens 27 performs an autofocus operation for adjusting the imaging position of the subject.

  The imaging lens shown in FIG. 3 is an inner focus lens type in which an autofocus lens 27 is disposed in a lens unit. In this inner focus lens type, since the auto focus lens 27 can be made small, the auto focus lens 27 can move quickly and the structure can be simplified, but the variator (zoom lens) 32 is moved. It is necessary to perform a focus correction operation. In general, a zoom lens of a home video camera uses this method.

  The macro correction lens 33 performs a correction operation on the autofocus lens 27 because the focus position is shifted when the variator (zoom lens) 32 is moved during macro photography. This correction amount is calculated by the CPU 10 based on the position data of the variator (zoom lens) 32 and the autofocus lens 27.

  When the macro / zoom operation unit 11 selects and operates the macro shooting mode and the zoom shooting mode, the macro zoom control system 12 drives the shooting lens 1 via the motor drive circuit 8 to the AF control unit 2. The focus control is controlled so as to be limited to a limited range where the in-focus state is set.

Thus, when shooting is performed while performing a zoom operation in the state of being close to the subject in the macro shooting mode, the movement range 36 of the variator (zoom lens) 32 is a variator at the time of macro indicated by 35 as compared with the normal AF time indicated by 34. (Zoom lens) Limited to the range of movement. The macro variator (zoom lens) movement range 35 is a range in which the focus control of the AF control unit 2 is in an in-focus state. Accordingly, it is possible to control the zoom operation within an appropriate range within the movement range 35 in the macro shooting mode.
The imaging lens is not limited to the inner focus lens type shown in FIG.

FIG. 4 is a diagram showing the structure of another imaging lens (front lens focus lens).
In FIG. 4, in this imaging lens, a variator (zoom lens) 41 and a compensator (zoom correction lens) 42 are movable in the optical axis direction in a cylindrical lens unit between the focus lens 27 and the CCD 3. Has been placed. The variator (zoom lens) 41 performs a zoom operation for changing the focal length. The compensator (zoom correction lens) 42 operates in conjunction with the variator (zoom lens) 41 so that the focus position does not shift during the zoom operation. The autofocus lens 27 performs an autofocus operation for adjusting the final position of the subject as described above.

  The imaging lens shown in FIG. 4 is a front focus lens type in which an autofocus lens 27 is disposed at the tip of a lens unit. This front-lens focus lens type can perform a manual zoom operation while maintaining the focus position by the function of the compensator (zoom correction lens) 42 even during the zoom operation, but the auto focus lens 27 is large. The autofocus lens 27 cannot move quickly. In general, a zoom lens of a film type camera or a professional video camera uses this method.

FIG. 5 is a diagram illustrating each lens group (several lenses) composed of n lenses in an actual imaging lens.
As shown in FIG. 5, the above-described imaging lenses are not configured one by one, but in order to obtain necessary optical characteristics, the first group 51, the second group 52, the third group 53, and the fourth group 54 are actually used. As described above, each lens group (several lenses) 55 is composed of n lenses.

A zoom auto lock icon is displayed (step S6).

  On the other hand, when it is determined in step S1 that the macro button 61 has not been pressed, the controller 63 of the CPU 10 next determines whether or not the zoom button 62 has been pressed (step S7). When it is determined in step S7 that the zoom button 62 has been pressed, the controller 63 switches the switch 66 to the normal zoom drive table 64 side (step S8).
