Abstract
A gated camera divides a depth direction into a plurality of ranges and generates a plurality of slice images corresponding to the plurality of ranges. An illumination device radiates probe light. A controller controls a light emission timing of the illumination device and an exposure timing of an image sensor. An image processing device generates a slice image based on a sensor image transmitted from the image sensor. The image processing device selects M (M≥2) pixel values in ascending order of pixel values for each line of the sensor image, calculates an average value of the M pixel values, and subtracts the average value from each pixel value of the corresponding line.
