Title:
PICTURE PROCESSOR FOR MOBILE WORK MACHINE
Document Type and Number:
Japanese Patent JPH02301810
Kind Code:
A
Abstract:
PURPOSE:To improve the throughput and detecting accuracy of the processor by successively making scan toward an objective area side from a nonobjective area side in such a way that, upon detecting a picture output changing point, the scan to the column is stopped and next column is successively scanned. CONSTITUTION:It is arranged that scan is performed toward an objective area N side from a nonobjective area M side at the time of retrieving picture output changing points (xm, ym) and (xn, yn). Therefore, when one output changing point is retrieved in the course of the scanning started from one picture end, the scan to the column is stopped and next column is successively scanned. Therefore, not only the edge detecting work can be made faster and the throughout can be improved, but also the detecting accuracy can be improved.
