Image capturing element, image capturing apparatus, image capturing method, image capturing system, and image processing apparatus

Abstract

The invention provides a kind of imaging element, a device of the element, an imaging method, an imaging system and an image-processing device. An imaging device (1) comprises: a sector scanning image-processing device (10) for reading the pixel signals in the whole exposed area (the whole scanned area) by means of damaging readout, and outputting the pixel data of the pixel signals in order according to the exposed pixel signals of different exposing time in different readout area by means of non-damaging readout in normal exposing period; and an image-processing system (12) for generating a background image based on the pixel data of the whole exposed area, generating an image of a moving area according to the pixel data corresponding to the exposure of different exposing time in a special area and generating an imaging figure by combining the background image with the moving area image.

Description

technical field [0001] The present invention relates to an imaging element, an imaging device, an imaging method, and an imaging system capable of reading charges from a photoelectric conversion element using a destructive readout method and a nondestructive readout method, An image processing device that generates captured image data from the read charges. Background technique [0002] Conventionally, there are destructive readout methods and nondestructive readout methods as methods for reading charges from an image sensor (photoelectric conversion element) of an imaging device. [0003] Here, the destruction readout method is a method that is accompanied by reset processing for clearing charges accumulated in the photoelectric conversion elements when reading charges (pixel signals) from the photoelectric conversion elements. [0004] In addition, the non-destructive readout method is a method in which the charge stored in the photoelectric conversion element is not eras...

Problems solved by technology

[0011] However, in the prior art of the above-mentioned Patent Document 1 and the above-mentioned Patent Document 2, although a wide dynamic range can be realized, for example, when the nearby monitoring object moves relative to a dark background, if the frame rate (exposure time ) is consistent with the movement of the monitoring object, the captured image may become an image with a blurred background and cannot recognize the background content

On the other hand, if the background is photographed according to the exposure, the frame rate (exposure time) becomes longer, so there is a problem that the captured image becomes an image in which the movement of the surveillance object cannot be judged.
