- the partial background data is data that displays at least a part of the image represented by the background data including the subject area 82, that is, only the combined area on the display 26, and thus is compared with the case where the image represented by the background data is displayed.
- the subject area is displayed large. This makes it easy to confirm the composition.
- the partial background data is the number of pixels (32Ox240) that fits in the display area (320x240) of the LCD 26, and the number of pixels in the horizontal direction is also the number of pixels in the vertical direction.
- the number is also within the range of the number of pixels that can be displayed on the LCD 26, it is not necessary to perform a process of thinning out or interpolating the number of pixels when displaying on the LCD 26.
- partial background data is created in advance, that is, when the removable memory 57 is attached. There is no need to wait for the process of extracting the data to be represented and the process of converting the number of pixels of the extracted data to fit within the display area of the display.
- the subject data and the background data can be synthesized and displayed in a short time. In addition, since the operator does not have to wait, it is possible to reduce the possibility of missing the timing of shooting.
- the digital still camera 1 of this embodiment stores the created partial background data in a nonvolatile manner.
- the operator only has to instruct the creation of the partial background data once to store it in the dynamic memory, and only once has to wait for the conversion of the number of pixels.
- the digital still camera 1 of the present embodiment creates a partial background file 90 and a reduced background file 95 when the removable bubble memory 57 is mounted, but has means for instructing creation, and an operator It may be created when instructed.
- a digital still camera has been described as an example, but the present invention may be applied to a digital video camera.
