Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 解像度が良く、モアレが少なく、かつS/N 比の良好なカラー撮像装置を得る。 【構成】 R、G 1 、G 2 、Bの色フィルタがベイヤー 配列で設けられている撮像素子101から得られる各信 号を補間フィルタ106〜109で同時化した後、加算 器129、130、139、140でR−G 1 、R−G 2 、B−G 1 、B−G 2 信号を得、これらの信号から色 差信号生成回路141、色差マトリクス113等により 色差信号R−Y、B−Yを生成するように構成する。 【効果】 ナイキスト周波数のキャリアが抑制され、モ アレが少なく、ナイキスト周波数までの解像度を有する S/N比の良好な画像が得られる。 (57) [Abstract] [Purpose] Good resolution, little moire, and S / N A color image pickup device having a good ratio is obtained. [Configuration] R, G 1 , G 2 , and B color filters are provided in a Bayer array. Signals obtained from an image sensor 101 are synchronized by interpolation filters 106 to 109, and then added by adders 129, 130, and 139. , 140 at R-G 1 and R-G 2 , BG 1 and BG 2 signals are obtained, and color difference signals RY and BY are generated from these signals by the color difference signal generation circuit 141, the color difference matrix 113 and the like. [Effect] Carriers of the Nyquist frequency are suppressed, moire is reduced, and an image having a good S / N ratio with resolution up to the Nyquist frequency can be obtained.
