ABSTRACT:
A scanner device including a line sensor, an AD conversion circuit for AD-converting an inputted image signal, a memory for storing therein a digital signal which is outputted from the AD conversion circuit, a DA conversion circuit for DA-converting the digital signal which is stored in the memory, an encoder for executing conversion to a video signal on the basis of an output from the DA conversion circuit, and a controller for outputting an image signal which is outputted from the line sensor, to digital RGB data which are more in the number of picture elements than the number of stored picture elements of the memory by the auxiliary utilization of said memory. Thus, the scanner device makes it possible to execute video output with respect to a domestic television monitor, although the scanner device is a scanner having high resolution, and further, at a reduced memory capacity.
