ABSTRACT:
A film scanner enabling TV display includes a line sensor for converting a one-dimensional optical image into a line image signal. An A/D converter converts the line image signal into a digital signal. An image memory stores the digital signal in units of a line image. A D/A converter converts a line image signal read from the image memory into an analog signal. A sync signal generator generates a sync signal used to produce a video signal. An encoder outputs a given video signal on the basis of an analog signal output from the D/A converter and the sync signal. A control unit controls at least accumulation of the line sensor in response to the given timing of the sync signal, to control reading or writing of the image memory.
