Abstract
PURPOSE: To make various optical reads possible by varying resolution and a slice level by providing one optical system and a sensor.
CONSTITUTION: On document 1, there are figure area 10, character area 11, and mark area 12 with entered data. Document 1 is set in a reader to perform scanning photoelectric conversion of its data. In this case, the scanning resolution depends upon the number of photo detectors of the sensor within the visual field in the main scanning direction. The value is the maximum resolution required for the mechanical processing of marks, characters and figures processed by this device. Picture signals read out are sent to corresponding processing circuits with the resolution varied depending the information content. The information content is discriminated by a discrimination code provided to the area and then sliced at an adequate level before being decoded.
