Abstract:
1. An imaging apparatus comprising: a light source unit that is capable of emitting a plurality of types of illumination lights; a sensor in which a plurality of pixels that each generates, upon receipt of light, an electrical signal through photoelectric conversion are arranged on a two-dimensional plane, wherein a control unit that performs controlling to read the pixel information from the pixels belonging to the read target area by each frame, wherein a light source controller that controls the light source unit to sequentially emit, by each illumination period of a length corresponding to at least two frame periods, the illumination lights in synchronization with start of the exposure period of the horizontal line that is to be read first from the sensor, an interpolated image generator that generates interpolated image data for interpolation between two pieces of image data acquired at consecutive times among image data acquired by the control unit, by using pixel information which is based on light received by the sensor during a period including a timing at which the illumination lights are switched; wherein the control unit performs the predetermined controlling by performing controlling to exclude, from a predetermined processing target, image data corresponding to the pixel information read by the sensor during a first frame period of the illumination period among the pixel information read by the sensor in each frame, while on the other hand by acquiring image data corresponding to the pixel information read by the sensor during other frame period of the illumination period among the pixel information read by the sensor in each frame.
