Abstract

Official abstract text for this publication.

An image pickup apparatus includes a detection unit in which a matrix of pixels converts radiation or light into analog electrical signals, a reading circuit configured to perform signal processing operation by reading the analog electric signals on a row-by-row basis, an A/D converter configured to convert a pixel signal output from the reading circuit into pixel data, and a correction processing unit configured to correct the pixel data. A control unit performs control processing so that the reading circuit outputs reset signals to the A/D converter in a period in which the signal processing operation of a predetermined row is performed, the A/D converter converts the reset signals into pieces of reset data in the period, and the correction processing unit averages the pieces of reset data output from the A/D converter and performs subtraction with the averaged reset data and the pixel data output from the A/D converter.

First claim

Opening claim text (preview).

What is claimed is: 1. An image pickup apparatus comprising: a detection unit having a matrix of a plurality of pixels for converting radiation or light into electric charge and outputting analog electric signals based on the electric charge; a reading circuit including a reset unit configured to output a plurality of reset signals, and configured to perform a signal processing operation for outputting the plurality of reset signals during an interval of outputting a plurality o…
