Image capturing apparatus, image capturing method, and image capturing circuit

摘要

Provided is an image capturing apparatus for capturing an image of a target object by optically scanning the target object by moving in a predetermined scanning direction. The apparatus includes a light-receiving device that is disposed on a light-receiving surface of the image capturing apparatus and accumulates an electric charge according to an amount of light received from a light detection window, a length of which in the scanning direction is shorter than a length in the scanning direction of an area defined as one pixel of the target object; and an output device that outputs the electric charge accumulated by the light-receiving device when the light-receiving device has completed the optical scanning of the area defined as one pixel.

1. An image capturing apparatus comprising:
a light-receiving device configured to perform an optical scan of a target object by accumulating an electric charge from an entire area of the target object during the optical scan only when the light-receiving device is disposed over a light detection window, a length of which in the scanning direction is shorter than a length in the scanning direction of an area defined as one pixel of the target object; and an output device configured to output a signal corresponding to the amount of electric charge accumulated by the light-receiving device when the light-receiving device has completed the optical scan of the area defined as one pixel, wherein the entire area of the target object is optically scanned by repeating the electric charge accumulation by the light-receiving device and the electric charge output by the output device.
