IPC: H04N5/44
Filed: 1991-03-07
Abstract: PURPOSE: To satisfactorily reduce edge flicker by comparing the luminance signals of adjacent two fields, forming a flicker correction signal and controlling signal delay and acceleration based on this signal. CONSTITUTION: The odd field of a luminance signal is stored in a memory 100 with a two field capacity, compared with the even field by a detector 110, a flicker correction signal requiring an amplitude and phase is formed, and supplied through a correction memory to a correcting device 130. The similar repetition is operated to successive adjacent fields such as the even field and the odd field of the next frame. The device 130 delays the even field by using a delay line at the time of judging that signal change is generated in the even field of the first frame based on the correction signal, and substantially accelerates the odd field without using the delay line at the time of judging that it is generated in the odd field. Edge flicker is satisfactorily reduced without affecting contrast by acceleration and deceleration suited to this signal.

Abstract: PURPOSE: To make it possible to extract characters and line patterns separately with relatively-small memory capacity, by comparing a fixed threshold value to the size of a continuous area found by scanning on an original in the order of lines and then by making a continuous line-by-line check.  
     CONSTITUTION: Scan part 1 extracts picture information as a binary digital signal of every picture element by scanning on an original in the order of lines, and the 1st processing part 2 finds and stores the initial point and terminal point of a black run in one line in the 1st memory unit 4. The 2nd processing part 3 finds a continuous area on the basis of address information on the unfinished area of the prior line and address information on the black run of the current line. When the continuation is interrupted, the size of the continuous area is compared to that of a predetermined character to obtain a character area, which is stored in the 2nd memory part 6 and corresponding information is erased from the 1st memory part 4. Therefore, only small memory capacity is required since only information needed for line-by-line processing over the line-order scan is stored.
