Image processing device and processing method

对彩色摄影器件适用像素错开方法在短时间取得高分辨率的单色图像的图像处理装置，由摄影光学系统和；具有多组由重复使用了3色(R、G、B)过滤器中的1色(G)的4个过滤器组成的彩色过滤器，按各色生成像素数据的彩色摄影器件和；在上述图像形成面内使在上述摄影光学系统的图像形成面配置的上述彩色摄影器件仅偏移规定的像素量的偏移驱动装置和；图像合成部组成，图像合成部只从在上述偏移驱动前后生成位置关系不同的同一色(G)的像素数据生成并输出1幅单色图像。 An image processing apparatus for acquiring a monochromatic image of high resolution within a short time by using the pixel shift method for a color imaging device. The apparatus comprises an imaging optical system, a color imaging device including a plurality of sets of four filters two of which are used for a single color (G) selected from the three primary colors (R, G, B) for generating pixel data for each color, a shift drive unit for shifting the imaging optical system and the color imaging device relatively to each other by a length corresponding to a predetermined number of pixels in the imaging surface, and an image synthesizing unit, the color imaging device being arranged on the imaging surface of the imaging optical system. The image synthesizing unit generates one monochromatic image only from the pixel data of the same color (G) in different relative positions before and after the shift.
