ABSTRACT:
In an image read-out apparatus, a recording medium, on which an image has been recorded, is two-dimensionally scanned with a light beam. Light, which is radiated out of the recording medium during the scanning and which represents the image, is detected with a photoelectric sensor, and a time-serial image signal is thereby generated. In the course of generating the image signal, a peak value dectector sequentially detects peak values occurring at parts of the image signal. A light detecting sensitivity controller controls the sensitivity, with which the photoelectric sensor detects the light radiated out of the recording medium, in accordance with the peak values, which have been detected sequentially, such that the value of the image signal does not exceed a predetermined value. A correction device corrects the image signal in accordance with a signal representing the sensitivity, with which the photoelectric sensor detects the light radiated out of the recording medium.
