Abstract

Abstract Translated from Japanese (57)【要約】 【課題】レンズの色収差に起因して、撮像により得られ たカラー映像信号に基づくカラー映像内に色収差が発生 し、カラー映像の画質が低下する問題があった。 【解決手段】信号処理装置及び方法において、撮像によ り得られたカラー映像信号に基づくカラー映像内の基準 位置からの距離に応じた色収差の収差量を検出し、検出 した収差量に基づいて、カラー映像信号に対して色収差 を補正する所定の信号処理を施すようにした。また撮像 装置及び方法において、光電変換手段から出力されるカ ラー映像信号に基づくカラー映像内の基準位置からの距 離に応じた色収差の収差量を検出し、検出した基準位置 からの距離に応じた収差量に基づいて、カラー映像信号 に対して色収差を補正する所定の信号処理を施すように した。 (57) [Problem] There is a problem that chromatic aberration occurs in a color image based on a color image signal obtained by imaging due to chromatic aberration of a lens, thereby deteriorating the image quality of the color image. In a signal processing apparatus and method, an amount of chromatic aberration according to a distance from a reference position in a color image based on a color image signal obtained by imaging is detected, and color aberration is detected based on the detected amount of aberration. Predetermined signal processing for correcting chromatic aberration is performed on the video signal. In the imaging device and the method, the amount of chromatic aberration according to the distance from the reference position in the color image based on the color image signal output from the photoelectric conversion unit is detected, and the aberration according to the detected distance from the reference position is detected. Based on the amount, predetermined signal processing for correcting chromatic aberration is performed on the color video signal.
