Title:
IMAGE PROCESSOR AND ITS METHOD
Document Type and Number:
Japanese Patent JPH1141603
Kind Code:
A
Abstract:

To provide an image processor and image processing method in which motion detection accuracy of an input image is not deteriorated even when a part of processor elements is defective.

An image processor is provided with plural processor elements connected in cascade and a motion detection section 2 that is constituted of a minimum value discrimination circuit 31, a defect detection circuit 32 and an error output excluding circuit 33. The defect detection circuit 32 detects a defective processor element while a predetermined test pattern is inputted and stores the defective processor element and outputs defective information to the error output excluding circuit 33 as a control signal. The error output excluding circuit 33 outputs only outputs of the processor elements outputting normal difference values to the minimum value discrimination circuit 31 based on the control signal. The minimum value discrimination circuit 31 detects a motion vector based on reference pixel data imputted by the processor element outputting a minimum difference value.
