Abstract
The present invention relates to a block matching apparatus, and more particularly, to a block matching apparatus, in which a normal driving power and a low driving power are alternately applied to an absolute difference calculation unit for calculating an absolute difference between a pixel of a first image frame and a pixel of a second image frame corresponding thereto among two stereo image frames, and a low absolute difference of corresponding pixels calculated using the low driving power is compensated with a high absolute difference of adjacent corresponding pixels calculated using the normal driving power, so that since a separate estimation unit does not need to be provided, the block matching apparatus can be lightly manufactured in terms of hardware and can reduce power consumption.
