Abstract:
1. 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 comprising: light-receiving devices that are arranged on a light-receiving surface of the image capturing apparatus in a direction perpendicular to the scanning direction, where each light-receiving device has a plurality of light-receiving elements in the direction perpendicular to the scanning direction and accumulates an electric charge according to an amount of light received from the target object; and an output device that outputs the electric charge accumulated by each light-receiving device regularly at a predetermined output period which is determined in a manner such that the larger the length in the scanning direction of a light-receiving range for the target object, which is covered by the light-receiving device, the longer the output period, wherein: the length in the scanning direction of the light-receiving range for the target object is represented by: where h denotes a distance obtained by orthogonal projection of each light-receiving device onto the target object, θ denotes an angle of view of the light-receiving device in the scanning direction, and α denotes an angle between a direction of the orthogonal projection of the light-receiving device onto the target object and a light-receiving direction of the light-receiving device.
