Title:
アレイ内光学的黒画素のためのクロストーク補償を有する感光撮像システムおよびデバイス
Document Type and Number:
Japanese Patent JP7052040
Kind Code:
B2
Abstract:
A light sensitive imaging system adapted for determining a crosstalk value of an OB (optically black) pixel arranged in a pixel array, the system comprising at least one image sensor comprising at least one pixel array, and processing means. The pixel array comprises a plurality of color channel pixels (CP1,…,CPn) and at least one OB pixel (OB1,…,OBn). The processing means is adapted for detecting an intensity value (IVOB1) of a color channel of an OB pixel (OB1), detecting an intensity value (IV1) of a neighboring color channel pixel (CP1), and calculating a crosstalk value (CV1) for the OB pixel (OB1) based on the intensity values (IVOB1; IV1).
