ABSTRACT:
A line sensor having a plurality of photoelectric conversion elements is provided for producing image data dependent on an optical image of at every scanning line. Marker data of a green line is generated on demand. A changeover switch is provided for selectively switching the image data and the marker data, and a display memory is provided for storing the image data and marker data. A controller produces a first write signal for writing the marker data and a second write signal for writing the image data at every scanning line. A timing signal is generated for deciding timing for producing the first write signal and the second write signal. A monitor is provided for displaying the green line dependent on the stored marker data and an image dependent on the stored image data, superimposing on the green line.
