Abstract: An image capturing device includes an image capturing section that captures first video data having a frame cycle of a first frame cycle and an exposure time for one frame shorter than the first frame cycle, an image acquisition section that acquires the first video data captured by the image capturing section, a detection section that detects a flicker of a light source in the first video data, and an image capturing frame cycle control section that controls the frame cycle of the image capturing in the image capturing section. The image capturing frame cycle control section changes the frame cycle of the first video data captured by the image capturing section from the first frame cycle to a second frame cycle, which is a frame cycle shorter than the first frame cycle, in a case where the detection section detects the flicker.

Abstract: A CPU performs an amount-of-exposure control process to thereby function as a first control unit that controls the exposure time of pixels to control the amount of exposure of the pixels for each of a plurality of division regions obtained by dividing a captured image and as a second control unit that controls the light transmittance of an ND filter to adjust the difference in amount of exposure between the plurality of division regions for each of which the amount of exposure is controlled by controlling the exposure time. On a touch panel display, the captured image obtained with the amount of exposure controlled by the CPU in accordance with a combination of the exposure time and the light transmittance of the ND filter is displayed.
