IMAGE CAPTURE CONTROL DEVICE, IMAGE CAPTURE DEVICE, IMAGE CAPTURE CONTROL METHOD, AND IMAGE CAPTURE CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/054031
Kind Code:
A1
Abstract:
Provided are an image capture control device, an image capture device, an image capture control method and an image capture control program wherein it is possible to prevent occurrence of inconsistencies in brightness of captured images and to prevent decrease in efficiency of using auxiliary light. A digital camera 100 is provided with: an image capture control unit 11A that drives an image capture element 5, by means of a rolling shutter system, for capturing an image of a subject; and a light emission control unit 11B that causes a light emission device 30 to emit therefrom an auxiliary light a plurality of times during implementation of this image capture. It is arranged that the difference Δt in timing of starting an exposure, which is started by the aforementioned driving, between two adjacent pixel rows 62 be of a value other than the value of 1/n times (where n is an integer equal to or greater than one) an exposure time during which the exposure is implemented, and the light emission control unit 11B controls the light emission period of the auxiliary light to be equal to the time of m times (where m is an integer equal to or greater than one) the aforementioned difference.
