Title:
TELEVISION TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JPS6467088
Kind Code:
A
Abstract:
PURPOSE: To prevent the generation of blocking errors by relating the limited quantity of kinetic information with an area larger than the conventional area and performing comparison not concerning a single motion vector but concerning respective vision information points from a lot of motion vectors to respective areas on the other hand. CONSTITUTION: A signal generator generates a kinetic information signal from the most superior motion vector and at a receiver, concerning the comparison of number of times corresponding to a limited number, spatial offset vision information is provided on a correspondent field concerning the adjacent image of offset determined by respective motion vectors suitably selected for an area containing vision information on the subject of comparison. The comparison is performed concerning respective image information points in areas at the main parts of respective fields between the vision information on vision signals in the area of the 1st field, and the vision information for the up converted image signal is led out of the received vision signal while using this result. Thus, the blocking error is prevented.
