Abstract
PURPOSE: To allow a simple solid scanner used for an optical character reader, etc., to generate its output with resolution variable by converting a digital signal from the solid scanner into an analog signal and by performing A/D conversion after sampling at a period which corresponds to resolution.
CONSTITUTION: Information on slip 1 is read out by solid scanner 2 of a self-scanning type solid photoelectric converter in a digital signal, which is converted into an analog signal in a time-axial direction by D/A converter 3. This analog signal converted in the time-axial direction is applied to sampling circuit 5 via smoothing circuit 4 and sampled at a fixed frequency which corresponds to resolution. Then, sampled analog signals are A/D-converted again to obtain a variable-resolution output signal.
