no. 1 Embodiment
[0100] A first embodiment of the present invention will be described. Such as Figure 4 As shown, the effective pixel area 33 in the shape of a rectangle is set in the entire area where the light-receiving pixels are arranged in the imaging element 33. A . Each light-receiving pixel performs photoelectric conversion on the optical image of the subject incident through the optical system 35 and the diaphragm 32 , and outputs an electrical signal obtained through the photoelectric conversion as a light-receiving pixel signal.
[0101] will pass from the active pixel area to 33 A The image formed by the light-receiving pixel signal output by each light-receiving pixel within is called the original image. In the first embodiment, it is assumed that the angle of view of the original image and the effective pixel area 33 A The field of view of the images imaged in the ensemble is the same. The angle of view of the original image is an angle representing the range of the imaging...
no. 2 Embodiment
[0133] A second embodiment of the present invention will be described. The matters described in the first embodiment are applicable to the second embodiment as long as there is no contradiction.
[0134] In the second embodiment, RAW zoom is used instead of the electronic zoom described in the first embodiment. First, refer to Figure 16 as well as Figure 17 (a) and (b) describe RAW zooming. able to Figure 16 The readout control unit 61 and the resolution conversion unit 62 are preset at figure 1 In the main control part 13 of. In the second embodiment, for concrete description, it is assumed that the effective pixel area 33 of the image sensor 33 A There are (4000×2000) light-receiving pixels in . That is, set in the effective pixel area 33 A , the number of light-receiving pixels in the horizontal and vertical directions is 4000 and 2000, respectively. 1000000 is called 1 megabyte. Therefore, (4000×2000) is also called 8 megabytes. In addition, it is assumed th...
no. 3 Embodiment
[0162] A third embodiment of the present invention will be described. In the third embodiment, the operation of the imaging device 1 in the playback mode will be described.
[0163] Figure 22 It is a block diagram of parts particularly involved in the work related to the third embodiment. Among the images recorded on the recording medium 16 , an image designated by the user is read from the recording medium 16 as a reproduced original image. A reproduced original image as an input image is displayed on the display unit 15 after being cropped and enlarged according to the reproduction magnification specified by the user. For example, the user can use the zoom button 21 to designate the reproduction magnification. with the symbol EF REP Indicates reproduction magnification.
[0164] Figure 22 The electronic zoom processing unit 54 and the output image generation unit 55 have the same Figure 5 Same functionality as the above section. However, in the third embodiment, t...
