Abstract
An encoding apparatus includes an interval register (250), a calculator (208, etc.), means for providing a potential shift-amount (Shift.sub.-- LSZ) of the interval register for the image data in a specific condition (LPS), a shift-amount decision circuit (258), a shift-amount register (259), and a shifter (251). The interval register stores plural bits of interval data to be used for encoding the image data. The calculator updates the interval data in the interval register. The shift-amount decision circuit generates an actual shift-amount of the interval register, in accordance with the potential shift-amount and the output of the calculator. The shift-amount register stores the actual shift-amount, supplied from the shift-amount decision circuit. The shifter shifts the interval data in the interval register a plurality of bits at one time, in accordance with the actual shift-amount stored in the shift-amount register.
