IPC: G06T1/00
Filed: 1991-11-28
Abstract: PURPOSE:To provide an original reading device which can read both reflected and transmitted originals in a simple constitution and with a simple operation. CONSTITUTION:When an reflected original is read, the reflected light sent from the original is turned into an electric signal through an image sensor 6. Then the signal raised to gamma-power by a gamma correction circuit 10 is outputted. When a transmitted original is read, the light transmitted through the original, reflected by an original holder plate 2 and transmitted again through the original is turned into an electric signal through the sensor 6. Then the signal raised to gamma.alpha-power by the circuit 10 is outputted. In other words, the signal that passed twice through the original for reduction of the light quantity is outputted after correction when the transmitted original is read.
