Abstract

An image capture apparatus generates synchronous detection images under different exposure conditions in such a way that each synchronous detection image is obtained by subtracting the output values of an image captured with no light projected from the output values of an image captured with light projected, selects one or more pixels from the rest of the pixels at each position of the two or more synchronous detection images under the different exposure conditions excluding the pixel having the lowest output value, and generates a synchronous detection image by using the selected pixels.

First claim

The invention claimed is:

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…
