PROBLEM TO BE SOLVED: To provide a light flight distance measuring device capable of enhancing the frame rate of exposure in a short time while expanding the dynamic range.SOLUTION: The light flight distance measuring device has plural pixels in a plane, which are segmented into a pixel group (pixel group including pixel A) for exposing a long period of time and a pixel group (pixel group including pixel B) for exposing a short period of time. While a receiving element of the pixel group, which performs a longtime exposure, performs the long time exposure to acquire a measured value once in the period of time, the receiving element of the pixel group, which performs short time exposure, performs the exposure four times to acquire the measured value four times.SELECTED DRAWING: Figure 4 |
