Title: Optical character reader
Inventor: KAWAI KOICHI
IPC: G06K9/72
Filed: 1987-02-20
Abstract: PURPOSE:To read script characters without misreading them even if they are connectedly written by previously assuming misreadable characters, preparing the codes, and correctly converting a content which is read. CONSTITUTION:The characters of a document 1 which are written in script are read in a scanner 2, are coded in a character encoder 4 in a reader mainbody 3, and are temporary stored in a register 5. Since code information of misreadable characters are previously stored in a code exchange part 6, the character codes which are misread are at first stored in a register 7 as they are without being exchanged. With the operation of an arithmetic control part 9, words in a storage part 11 are sequentially stored in a register 12, and an agreement detection part 8 checks them repeatedly. An address detection part 10 detects last addresses even if there are not any agreement words. The address detection part 10 instructs an exchange part 6 for the exchange of the character codes, and sequentially start exchanging code information of misreadable characters. The above action is repeated, and the correct character code is stored in the register 7. It is executed until the detection part detects agreement.

Title: Automatic iris control circuit
Inventor: WATANABE OSAMU
IPC: H04N5/238
Filed: 1994-03-09
Abstract: PURPOSE:To make possible convergence in a short response time even when the output of an imaging device is in a saturation state by providing a high- luminance expanding circuit and amplifying the high-luminance part of a video signal. CONSTITUTION:Between an image pickup means 3 and a detecting means 6, a high-luminance expanding means 11 is provided to enlarge the gain of an output signal from the image pickup means 3 only near the level to be saturated. When the quantity of incidental light is changed and the output of the image pickup means 3 is turned to the saturation level, that output is amplified to a larger value by the high-luminance expanding means 11 and inputted to the detecting means 6 so that the output of the detecting means can be a larger value and much larger driving force can be provided in a direction to close an iris 2. Therefore, the time from the change in the quantity of incidental light to the reduction of the output from the image pickup means rather than the saturation level is shortened. Therefore, when the iris 2 is gradually closed and the output level of the image pickup means 3 is reduced rather than the value near the saturation level, the gain of the high-luminance expanding means 11 is made 1-fold, and an automatic iris operation is converged.
