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

Abstract

The invention provides an imaging element and its device, an imaging method, an imaging system and an image processing device. The imaging device (1) is configured to include: an area-scanning-compatible imaging processing system (10), which reads out pixel signals in all exposure areas (all scanning areas) in a destructive readout during an exposure period of a normal exposure time, and uses The non-destructive readout method reads out the pixel signals of exposures of various exposure times in the moving region by various types, and sequentially outputs the pixel data of these read out pixel signals; and an image processing system (12), which is based on the total exposure Based on the pixel data of the area, a background image is generated, and based on the pixel data corresponding to the exposure of a plurality of types of exposure times in a specific area, an image of a moving area is generated, and the generated background image and moving area image are synthesized to generate a captured 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.
