Abstract:
1. An image processing device comprising: a storage section that stores a low-resolution frame image acquired based on a light-receiving value, a light-receiving unit being a unit for acquiring the light-receiving value, the light-receiving unit being set corresponding to a plurality of pixels of a color image sensor that are adjacent in a horizontal direction and a vertical direction, and pixel values of the plurality of pixels included in the light-receiving unit being added up and read as the light-receiving value of the light-receiving unit; an estimation calculation section that estimates pixel values of pixels included in the light-receiving unit based on a plurality of low-resolution frame images stored in the storage section; and an image output section that outputs a high-resolution frame image having a resolution higher than that of the low-resolution frame image based on the pixel values estimated by the estimation calculation section, the storage section storing the low-resolution frame images acquired by sequentially performing a pixel shift process that shifts the light-receiving unit by one pixel of the color image sensor, light-receiving units obtained by sequentially performing the pixel shift process overlapping each other, the low-resolution frame images being stored in a number equal to a number of pixels included in the light-receiving unit, and the estimation calculation section estimating the pixel values of the pixels included in the light-receiving unit based on the low-resolution frame images obtained by sequentially performing the pixel shift process.
