Patent
Read-out level compensation in an optical reader system
TL;DR: In this paper, the white background plate data is reversed to obtain a reciprocal of the white level and the thus obtained reciprocal is memorized in a memory to compensate for the nonuniformity of the sensor outputs.
Patent
Image sensor output correcting system
TL;DR: In this article, an image sensor output correcting system is proposed, where a correcting region of an object being read is scanned in advance by means of a sensor array, thereby to provide a correcting signal based on the signal obtained in the scanning operation for correcting the scanning video signal of the region being read.
Patent
Output correcting system for facsimile
TL;DR: An optical image reading apparatus comprises a solid state image sensor having a plurality of blocks, means for generating video signals correponding to an object to be read out by the image sensor as mentioned in this paper.
Patent
Level determination for optical character reader
TL;DR: In this article, optical information on a card is read by an image sensor and then converted to a video signal represented by a digital signal of several bits through the use of an amplifier and an A-D converter.
