ABSTRACT:
A main operation unit (2) is connected to a control unit (4) which controls image processing units (5) to (9), the main control unit (2) includes a setting means for setting the image processing units (5) to (9) to which a sub operation means (3) is connected to the standard mode or the half-divide mode, the control unit (4) controls the image processing units (5) to (9) in response to instruction from the main operation unit (2) upon the standard mode, the control unit (4) controls the image processing units (5) to (9) in response to instruction from the main operation unit (2) upon the half-divided mode and the control unit (4) controls sub circuit blocks (5d) to (5f) within the image processing units (5) to (9) in response to instruction from the sub operation unit (3). Thus, the image switching apparatus can be composed of lesser circuits and such circuits can be used separately without waste as their uses are changed.
