Zusammenfassung:To provide a streaking correction circuit capable of performing noise suppression effectively for characteristic offset or noise in an imaging screen.SOLUTION: A streaking correction circuit in the present disclosure consists of a correction signal generation part for generating a correction signal on the basis of the signal of a shaded pixel in a shading part provided at the end of a pixel array part where pixels including a receiver are arranged in a matrix, and a correction processing part performing correction processing for the signal of effective pixels in the pixel array part, by using a correction signal generated in the correction signal generation part. The correction signal generation part divides a captured image into multiple regions, with reference to the position of a singular point in the captured image, and generates a correction signal in each divided region by using the signal of the shaded pixel. The correction processing part performs correction processing of each divided region by using the generated correction signal.SELECTED DRAWING: Figure 7 【課題】撮像画面内の特徴的なオフセットやノイズに対して効果的にノイズ抑制を行うことができるストリーキング補正回路を提供する。【解決手段】本開示のストリーキング補正回路は、受光部を含む画素が行列状に配置されて成る画素アレイ部の端部に設けられた遮光部の遮光画素の信号を基に補正信号を生成する補正信号生成部、及び、補正信号生成部で生成された補正信号を用いて、画素アレイ部の有効画素の信号に対して補正処理を行う補正処理部から成る。そして、補正信号生成部は、撮像画像内の特異点の位置を基準として、撮像画像を複数の領域に分割し、分割した各領域毎に遮光画素の信号を用いて補正信号を生成する。補正処理部は、分割した各領域毎に生成された補正信号を用いて補正処理を行う。【選択図】 図7
