Exposure control apparatus including a spatial light modulator |
摘要 |
An exposure control apparatus has a lens, a photoelectric conversion device, and a spatial light modulator. The spatial light modulator varies the amount of light received from the lens and reflected to the photoelectric conversion device. A control unit controls the spatial light modulator, and thus the exposure of the image focused on the lens, based on output from the photoelectric conversion device.
