Abstract
An image sensor output correcting system wherein 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, characterized in that the video signal obtained during the scanning operation of the correcting region is sampled with a predetermined interval, the video signals of the sensor corresponding to a plurality of scanning lines are compared, and the maximum value is stored as the correcting signal, whereby high speed scanning can be made without degrading the correcting function as compared with a system where the outputs of the respective sensors of the sensor array are analog to digital converted to generate the correcting signal.
