Title: Optical character reader
Inventor: MISHIMA KENJI
IPC: G06K9/20
Filed: 1994-12-06
Abstract: PURPOSE: To provide the optical character reader with which a character can be read even when a density of a description frame is high, or the density of the character is low to almost the same extent as that of the description frame and further when the character is overlapped with the description frame. CONSTITUTION: When a scanner part 2 scans a slip and detects a multilevel image, a description frame position detecting part 4 detects the position of the description frame on the slip based on the multilevel image and a description frame density detecting part 5 detects the density of the description frame from the multilevel image. A binarizing part 6 binarizes the multilevel image while defining the detected density of the description frame as a threshold value for the part of the description frame in the multilevel image and defining the density of background of the slip as a threshold value for parts except the description frame. Based on the binary image, a character recognition part 8 performs the recognition processing of the character.

Title: Circuit for detecting non input
Inventor: NISHIZAWA YOSHIJI
IPC: H04N19/00
Filed: 1987-11-30
Abstract: PURPOSE:To prevent production of noise on a screen before TV conference start in the case of an interrupted input signal by detecting the presence of the input signal depending on the difference from the period of a counter generating a timing signal. CONSTITUTION:In the case of the presence of a video input signal, a counter 1 starts from 1 by an input synchronizing signal (1) and counts a period (n) of the input signal as the count (3) and repeats it for n-period. If the input video signal is interrupted, since no input synchronizing signal (1) is sent, the count is advanced up to (n+1), an AND circuit 5 detects the output (3) to send a no-input detection signal. Simultaneously, the signal (2) is fed to an OR circuit 4 to start the counter 1 from 1 and the count (3) is repeated by (n+1) periods this time. Thus, the presence of the input signal (1) is monitored by monitoring whether the period of the output signal (3) is n or (n+1).
