Abstract
An image processing device includes a storage section, an estimation calculation section, and an image output section. A pixel is sequentially shifted so that overlap occurs to acquire a light-receiving value of the pixel as a low-resolution frame image. The storage section stores the low-resolution frame image. The estimation calculation section estimates estimated pixel values at a pixel pitch smaller than the pixel pitch of the low-resolution frame image. The image output section outputs a high-resolution frame image that has a resolution higher than that of the low-resolution frame image based on the estimated pixel values. The estimation calculation section calculates the difference between the light-receiving value of the pixel set at a first position and the light-receiving value of the pixel set at a second position, and estimates the estimated pixel values based on the difference.
