Camera device, exposure control method, and program |
摘要 |
A camera device is provided with an imager that outputs a long exposure signal and a short exposure signal within one field period; a knee processor that compresses a long exposure signal having the luminance level of a knee point or higher at a compression rate (i.e., decreases an inclination of an incident light amount-luminance level line, representing a variation in a luminance level with an amount of incident light); and a knee controller that adjusts the knee point and the compression rate according to a luminance level of a synthesized signal obtained by synthesizing the long exposure signal and the short exposure signal. In this knee control, the knee point decreases with an increase in the luminance level of the synthesized signal, and the inclination is adjusted to approach an original inclination thereof.
