Claim Text:
1. An image capture apparatus comprising: an image capture unit configured to capture an image by using a photo detector element which provides an output value varied depending on a light reception volume; a projector unit configured to project light to an area targeted for image capture by the image capture unit, in synchronization with the image capture by the image capture unit; a synchronous detection processor configured to obtain a synchronous detection image by subtracting an output value of an image captured with no light projected by the projector unit, from an output value of an image captured with light projected by the projector unit; an exposure controller configured to control the image capture unit and the projector unit in such a manner as to obtain two or more synchronous detection images under different exposure conditions; and an image generator configured to select one or more pixels from the rest of pixels at each position in the two or more synchronous detection images under the different exposure conditions excluding a pixel having a lowest output value, and generate a synchronous detection image by using the selected one or more pixels.
