Abstract:
1. An imaging apparatus comprising: an imaging device that is configured to image an imaging subject, pixels of the imaging device being arrayed in two dimensions and the imaging device being equipped with a pixel addition function that performs pixel addition of a plurality of pixels in a horizontal direction; a controller that is configured to control a pulse width of horizontal synchronization signals outputted to the imaging device, such that a feed-through period and a signal period, in a case in which pixel addition in the horizontal direction is performed at the imaging device and imaging signals are outputted, are longer than a feed-through period and a signal period, in a case in which pixel addition in the horizontal direction is not performed at the imaging device; a noise reduction processor that is configured to execute noise reduction processing, which utilizes the fact of the feed-through period and the signal period, in the case in which pixel addition in the horizontal direction is performed, being longer than the feed-through period and the signal period, in the case in which pixel addition in the horizontal direction is not performed, by performing multiple sampling in the feed-through period and the signal period in the case in which pixel addition of a plurality of pixels in the horizontal direction is performed to reduce effects of noise produced in the imaging signals; and a pixel value calculator configured to calculate a pixel value on the basis of a first signal sampled in the feed-through period, and a second signal sampled in the signal period.
