PHOTOELECTRIC CONVERSION APPARATUS, METHOD FOR CONTROLLING PHOTOELECTRIC CONVERSION APPARATUS, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18488840 titled 'PHOTOELECTRIC CONVERSION APPARATUS, METHOD FOR CONTROLLING PHOTOELECTRIC CONVERSION APPARATUS, AND STORAGE MEDIUM

Simplified Explanation

The photoelectric conversion apparatus described in the abstract includes a photoelectric conversion element with avalanche photodiodes arranged in a pixel area to convert optical images. The apparatus can read signals from different pixel groups simultaneously, generate an image based on the read signals, acquire crosstalk information between pixels, generate correction information, and correct the image using this information.

• The photoelectric conversion apparatus includes a photoelectric conversion element with avalanche photodiodes arranged in a pixel area.

Original Abstract Submitted

A photoelectric conversion apparatus includes a photoelectric conversion element including a pixel area where a plurality of pixels composed of avalanche photodiodes for photoelectrically converting an optical image is two-dimensionally arranged, the photoelectric conversion element being configured to simultaneously read signals from a first pixel group and a second pixel group in the pixel area, at least one processor, and a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the at least one processor to generate an image based on the read signals, acquire characteristic information regarding crosstalk between the plurality of pixels, generate correction information based on the characteristic information, and perform a correction process on the image using the correction information. Correction information different between the first and second pixel groups is generated.
