Abstract
The image processor includes a ⅓ multiplier circuit that approximately multiplies an input value X by ⅓. The ⅓ multiplier circuit includes a loop operation circuit that repeatedly perform a predetermined operation by loops, and a setting circuit that sets a required number of loops in the loop operation circuit. The loop operation circuit includes a register that receives an input of an input value, a bit shift circuit that performs bit shift by 2 bits to the right on a value output from the register, and an adder circuit that adds an input value and a value output from the bit shift circuit, and inputs the added value to the register.
