In this case, the control unit 26 causes the AE processing unit 11 to execute AE processing and the AF processing unit 12 to execute AF processing (step S117).

  Subsequently, the control unit 26 drives the image sensor driving unit 7 to perform photographing using the electronic shutter (step S118).

  Thereafter, the control unit 26 causes the image processing unit 10 to perform image processing (see FIG. 5) on the captured image data (step S119).

  Subsequently, the display control unit 262 displays an image corresponding to the image data subjected to the image processing by the image processing unit 10 in a live view display (Step S120).

  Thereafter, when the imaging apparatus 1 is recording a moving image (step S121: Yes), the control unit 26 compresses the image data subjected to the image processing by the image processing unit 10 by the image compression / expansion unit 13 with a predetermined formation. Recording is performed in time series on the moving image file of the recording medium 19 (step S122). After step S122, the imaging apparatus 1 proceeds to step S112. On the other hand, when the imaging device 1 is not recording a moving image (step S121: No), the imaging device 1 proceeds to step S112.

  A case where the regeneration switch 166 is operated in step S102 (step S102: Yes) will be described. In this case, the imaging apparatus 1 executes a reproduction display process for displaying an image corresponding to the image data recorded on the recording medium 19 on the display unit 17 (step S123). Details of the reproduction display process will be described later. After step S123, the imaging device 1 proceeds to step S112.

It is determined whether or not an end reproduction end operation has been performed (step S308). Specifically, the control unit 26 determines whether or not the regeneration switch 166 has been operated. When the control unit 26 determines that the reproduction end operation has been performed (step S308: Yes), the imaging device 1 returns to the main routine of FIG. On the other hand, when the control unit 26 determines that the reproduction end operation has not been performed (step S308: No), the imaging device 1 returns to step S303.

  A case where the deletion switch 163 is operated in step S307 (step S307: Yes) will be described. In this case, the feature amount calculation unit 14 analyzes the scene at the time of shooting based on the image data corresponding to the image to be deleted and calculates the feature amount of the subject (step S309).

  Subsequently, the deletion reason estimation unit 15 estimates a plurality of deletion reasons based on the feature amount calculated by the feature amount calculation unit 14 (step S310).
