Title:
IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, AND ELECTRONIC DEVICE WITH THE IMAGE PROCESSING APPARATUS
Document Type and Number:
Japanese Patent JP2008306608
Kind Code:
A
Abstract:

To provide an image processing method and image processing apparatus capable of acquiring a high-precision and high-resolution image by performing on a still picture and a moving picture, respectively, super-resolution processing for acquiring a high-resolution image from a low-resolution image.

A high-resolution updating amount calculation section 443 determines a gradient based on a differential between a low-resolution estimated image estimated from a high-resolution image and a low-resolution real image given from frame memories 41, 42, thereby calculating an updating amount to be subtracted from the high-resolution image. At such a time, the number of times of operations in the high-resolution updating amount calculation section 443 based on the high-resolution image stored in a frame memory 45 is set in such a way that the number of times of moving picture photographing becomes less than the number of times of still picture photographing.
