Abstract
The present invention provides an image signal processor, comprising: (a) an input circuit for receiving and/or holding an image signal of N-bit binary data word, where N is a positive integer; (b) a data converter converting at least M-bit data of binary data into non-binary data having multiple bits, where M is a positive integer and N≧M≧2, wherein (c) all bits of the non-binary data have a weight which is equal to, or less than, that of the least significant bit of the M-bit data of binary data; and (d) the data converter outputting the each bit of the non-binary data in sequence starting from an equal data value.
