一种图像输入装置包含：像素移位光学装置，其允许在来自图像拾取光学系统的入射光的图像拾取装置上在一个像素到几个像素内水平和垂直地移动图像成形位置；图像拾取控制装置，其控制像素移位光学装置的像素位移条件；分辨率检测装置，其根据通过改变像素移位光学装置的像素位移条件读出的图像信息检测图像的分辨率；以及存储装置，其存储根据分辨率比预定值高检测的像素信息和/或根据与分辨率比预定值高检测的像素位置相对应的信息。 An image input device comprises: a pixel shifting optical means that allows displacing an image-forming position on the image-pickup device of the incident light from the image-pickup optical system within one pixel to several pixels horizontally and vertically; an image pickup control means that controls pixel displacement conditions of the pixel shifting optical means; a resolution detection means that detects a resolution of an image on the basis of image information read by varying the pixel displacement conditions of the pixel shifting optical means; and a storage means that stores pixel information detected based on that the resolution is higher than a predetermined value, and/or information corresponding to a pixel position detected based on that the resolution is higher than the predetermined value.
