Method of image format conversion and remote control device using the same

摘要

A method of image format conversion and remote control device using the same. Addition terms for a first layer are derived from an image conversion table. Every two addition terms are assigned to an addition group, obtaining a plurality of addition groups. The two addition terms of each addition group are added by using an adder to obtain addition terms for next layer thereafter. The bit number of the adder is equivalent to that of one addition term comprising the maximum bit number in every addition group. Finally, the addition process is repeated to obtain the operation result.
