Title: Segmenting method of character line and character
Inventor: KUROSE MORIZUMI
IPC: G06V10/20
Filed: 1982-02-25
Abstract: PURPOSE:To segment a character line and characters having a fixed inclination, by dividing a binary picture ito the line direction of picture elements and its perpendicular direction and blocking the picture to find cut the inclination of the line. CONSTITUTION:A picture signal read out by a scanner 1 in each line is binary- coded by a binary coding circuit 2, the existence of a black element is discriminated by a discriminating circuit 3 and the discriminated result is sent to a central processing unit CPU4. The CPU4 divides the binary-coded picture into the line direction and its perpendicular direction to block the picture, decides a master block by scanning the picture and detects the tendency of line inclination. Subsequently the CPU4 segments a line coupled with the master block, calculates the line inclination, checks the independency of the line and then segment the whole line. The segmented line is sent to a character recognizing circuit 10 through a buffer memory 9 and the characters are recognized.

At that time, the end of the surface that the area 4 and the area 5 face each other is given curvature so as to avoid field concentration. Then, rounded areas 4 and 5 are formed in the end of opposing sides, so electric field does not concentrate in the end. This makes it possible to obtain a horizontal light-receiving element that has uniform photomultiplier characteristics and that does not develop breakdown until a high voltage is applied.

Abstract: PURPOSE:To prevent superfluous integration and to integrate to an appropriate level all the time by providing a fetching electrode at the approximately central part of the longitudinal direction of a photodiode for a luminance monitor and promptly outputting from the photodiode for the luminance monitor. CONSTITUTION:When light is irradiated on plural photoelectric converting parts PDs aligned correspondingly to picture elements, a charge is generated, and the charge is accumulated in an accumulating part ST.

Consequently, response time for the output from the photodiode 9 for the luminance monitor becomes 1/4 of that at the time of fetching the charge from the edge of the photodiode 9 for the luminance monitor. Thus, since the output of the photodiode 9 for the luminance monitor responds promptly, as the result, a signal from an integral action time control part is outputted promptly, and the superfluous integration in the accumulating part ST can be prevented.
