摘要： Imaging apparatus performs controlling to read pixel information from pixels belonging to target area by each frame. One frame period is period from when an exposure period for exposing pixels on a horizontal line that is to be read first from among horizontal lines belonging to the target area of a sensor is started and until when reading of the pixel information generated by each of the pixels on the horizontal line is completed. The imaging apparatus sequentially emits, by each illumination period of a length corresponding to at least two frame periods, illumination lights in synchronization with start of the exposure period. The imaging apparatus performs a predetermined controlling by performing controlling to exclude, from predetermined processing target, image data corresponding to the pixel information read during first frame period of the illumination period, while by acquiring image data corresponding to the pixel information read during other frame period.
