Color co-site sampling is a system of photographic color sensing, wherein 4, 16 or 36 images are collected from the sensor and merged to form a single image. Each subsequent image physically moves the sensor by exactly one pixel, in order to collect R, G and B data for each pixel, known as microscanning. This is a viable alternative to the typical Bayer filter array of pixels which returns a lower quality images with interpolated pixel colors. ==Operation== Several images are captured and combined to a sharp resulting image. After the acquisition of each image a piezo mechanism moves the sensor by precisely the distance of one pixel and delivers the complete colour information for each detail and with the same sharpness in all three colour channels. Microscanning is essential for the method. 4 (2x2), 16 (4x4) or 36 (6x6) shots can be used for improved colour reproduction. * Advantages * * Higher resolution possible in comparison with the basic CCD pixel count * * No colour interpolation required * * Better sensitivity than a three-chip camera * * Live colour image possible at the basic CCD sensor's resolution * * Only one colour sensor required * Disadvantages * * Stable imaging conditions required due to microscanning * * Longer acquisition times because of multiple exposures 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Color co-site sampling」の詳細全文を読む スポンサード リンク
