  • Patent number: 10887527
    Abstract: An image capture apparatus capable of improving the quality of an image captured using illumination. A multi-eye image capture section has image capture sections that capture images in different image capture ranges partially overlapping with each other to generate a wide-angle image. A single-eye image capture section captures an image in part of the image capture ranges of the multi-eye image capture section and changes an image capture direction. When performing image capture using illumination, the exposure level of a first image capture section of the multi-eye image capture section, having an image capture range overlapping with the image capture range of the single-eye image capture section is controlled to be lower than the exposure level of a second image capture section having an image capture range not overlapping with the image capture range of the single-eye image capture section.
