ABSTRACT:
An image information output apparatus which includes a circuit for setting conditions for a "0" or a "1" level in an X direction, a circuit for setting conditions for a "0" or a "1" level in a Y direction with respect to each of respective image units over an entire output image plane divided into an X-Y matrix configuration, a circuit for generating an output timing signal for each of the image units, an AND circuit for ANDing two signals so as to output conditional signals at every generation of the output timing signal for each of the image units, one conditional signal being related to the X direction condition setting and one conditional signal related to the Y direction condition setting, a circuit for storing image information, and a circuit for outputting the stored image information, one image unit by one image unit, for each "1" level output signal of the AND circuit.
