Photographic device for obtaining a plurality of images at a time by rolling shutter method
摘要:
A photographic device includes an image sensor in which a plurality of pixels are arrayed. A vertical scan circuit selects horizontal drive lines of the image sensor in order. And a horizontal scan circuit reads out in order voltages due to electric charges from the pixels in the horizontal row which is selected by the vertical scan circuit. A plurality of optical lenses are arranged in a direction parallel to the vertical drive lines, and these optical lenses form images of the same photographic regions upon respective pixel regions which face them. The voltages due to electric charges are read out in order from the pixels, and a plurality of images are acquired with some time difference between them. The emission of light by a light source is controlled, so that photography in each of the pixel regions is performed in different photographic conditions.
