Image processing method and device, and program
First Claim
1. An image processing method for estimating an output image from a plurality of input images, comprising the steps of:
- detecting a positional relationship among the plurality of input images captured by image capture means for capturing an image each pixel of which has n pixel values; and
estimating the output image by identifying observed pixel components that should be taken into consideration from the plurality of input images for each pixel position of the output image, and producing the output image having (n+1) or more pixel values for each pixel based on the identified observed pixel components.

Abstract
The present invention relates to a method, apparatus and program for processing an image, capable of producing a sharp image. A digital camera 1 includes an imaging device 4 formed of a single-plane sensor that provides one color signal for each pixel. A plurality of images are captured at a high shutter speed by the imaging device 4 and stored in a frame memory 22 of a signal processor 7. The signal processor 7 detects a positional relationship among the plurality of images stored in the frame memory 22 and estimates a correct image with three color signals at each pixel, based on the detected positional relationship. The present invention is applicable, for example, to a digital camera.
