IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
First Claim
1. An image processing device comprising:
- an image processor configured to calculate a motion vector between image data of a target frame and image data of a reference frame in units of a block;
a reference frame image memory configured to retain image data of a past frame as the image data of the reference frame;
a primary memory configured to retain a matching processing range of the reference frame in calculation by the image processor; and
a secondary memory configured to read out and retain image data of a desired range from the image data of the reference frame stored in the reference frame image memory, the secondary memory reading out data of the matching processing range from the retained image data and supplying the read data to the primary memory.

Abstract
An image processing device includes an image processor that calculates a motion vector between image data of a target frame and image data of a reference frame in units of a block, and a reference frame image memory that retains image data of a past frame as the image data of the reference frame. Furthermore, the image processing device includes a primary memory that retains a matching processing range of the reference frame in calculation by the image processor, and a secondary memory that reads out and retains image data of a desired range from the image data of the reference frame stored in the reference frame image memory. The secondary memory reads out data of the matching processing range from the retained image data and supplies the read data to the primary memory.

6. An image processing method comprising:
-
calculating a motion vector between image data of a target frame and image data of a reference frame in units of a block; retaining image data of a past frame as the image data of the reference frame; retaining a matching processing range of the reference frame in such a state that reference to the matching processing range in the image processing is possible in calculation of the motion vector in the image processing; and reading out and retaining image data of a desired range from the image data of the reference frame retained in the reference frame retention processing, and reading out part of the retained image data and sending the part of the retained image data to the matching processing range retention processing. - View Dependent Claims (7, 8, 9, 10)
