Abstract
A subject observation system includes a light source, a light sensor, an image pickup device, a light source controller configured to cause the light source to alternately perform low-luminance illumination and high-luminance illumination at a predetermined luminance ratio, and a video processor configured to generate an HDR image, and sets a target sensor value S(n) in a temporarily succeeding n frame based on a sensor value S(n−1) in a temporarily preceding (n−1) frame and the luminance ratio.
