INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD AND PROGRAM
First Claim
1. An information processing apparatus comprising:
- a low-bit image generation unit configured to reduce a bit number assigned to a pixel in a criterion image and a reference image and generate a low-bit criterion image and a low-bit reference image; and
a motion vector information generation unit configured to detect a local motion vector, which is a motion vector for each of blocks constituting an image, from the low-bit criterion image and the low-bit reference image, and calculate a reliability of the detected local motion vector.

Abstract
There is provided an apparatus including: a low-bit criterion image generation unit that reduces a bit number assigned to a pixel in a criterion image and generates low-bit criterion image data; a low bit reference image generation unit that reduces a bit number of a reference mage and generates low-bit reference image data; and a motion vector information generation unit that detects a block-unit local motion vector from the low-bit criterion/reference images and calculates reliability of the detected local motion vector. By reducing the image bit number, it is possible to detect a local motion vector in a simple configuration. By calculating a global motion vector using a local motion vector according to reliability, even if a local motion vector is detected from an image of the reduced bit number, it is possible to calculate a global motion vector at higher accuracy.
