  • Patent number: 11025828
    Abstract: There is provided an imaging control apparatus including a control section that creates a first image by performing exposing to a pixel with first exposure by a first exposure time and creates a second image by performing exposing to a pixel with second exposure by a second exposure time in succession to the first image and a synthesizing section that synthesizes a synthesized image in which the first image and the second image have been synthesized and a selected image selected from either the first image or the second image. The control section decides the first exposure time and the second exposure time such that an image to be selected as the selected image in the synthesizing section is switched over on a basis of an exposure ratio being a ratio of an exposure time of the synthesized image and an exposure time of the selected image.
