Apparatus, method, and program for processing image

Abstract

An image processing apparatus includes a correction parameter calculation unit for calculating a motion blur correction parameter for motion blur correction on the basis of motion information indicating a motion of an image between unit images, the unit images forming image data, and shutter speed information obtained at the image capturing of the image data, and a motion blur correction processing unit for correcting a motion blur quantity contained in the image data by performing at least a process of reducing a motion blur in accordance with the motion blur correction parameter.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an apparatus, method and program for processing an image and, in particular, to an image processing technique for obtaining a high-quality image taking into consideration a motion image blur on the image.[0003]2. Description of the Related Art[0004]When a moving image taken at a high-speed shutter or an animation is displayed on a display device such as a projector or a display, the motion of a moving object contained in an image can be displayed in a discontinued fashion. This leads to frequent image degradation in which a user sees multiple images of the moving object. The degradation of the moving image due to motion unnaturalness is generally referred to as motion jerkiness. On the other hand, when a moving image taken at a low-speed shutter such as with an open shutter is displayed, the image of an object may lack detail or an edge of the image becomes blurred because of the effect ...

AI Technical Summary

Benefits of technology

The patent is about a method for reducing motion blur in images. The method involves calculating a motion blur correction parameter based on motion information and shutter speed information. Then, by using this parameter, the method reduces motion blur in the image data by performing a process of reducing motion blur. The technical effect of this patent is to improve the clarity of images by reducing motion blur.

Problems solved by technology

This leads to frequent image degradation in which a user sees multiple images of the moving object.

On the other hand, when a moving image taken at a low-speed shutter such as with an open shutter is displayed, the image of an object may lack detail or an edge of the image becomes blurred because of the effect of motion blur.

If the image is displayed as a moving image, the motion of a moving area within the image, in particular, a moving area at a high speed is not smooth.

Such an image looks unnatural to the vision of humans.

If the image is displayed as a moving image, the motion of a high-speed moving area within the image is smooth, but the entire image lacks sharpness.
