1. An image processing method for facilitating data transmission, comprising: capturing an image signal from an object with an image capture device; providing said image signal to an analog-to-digital converter for converting said image signal to X-bits binary digital signals consisting of bit (X- 1 ) to bit 0, wherein X is a natural number; transmitting said X-bits binary digital signals to image processing means for compressing said X-bits binary digital signals to a binary compressed data in a floating-point form of (1.n)*2 m, wherein a bit m represents the first bit with logic level “1” of said X-bits binary digital signals, and n represents the bits taken from said X-bits binary digital signals after the bit m, n is a non-negative integer, such that said binary compressed data in the floating-point form of (1.n)*2 m is outputted with a sequence of binary number representing a set of (m, n) and the latter n bits of the sequence of binary numbers are consisted of said n bits of said X-bits digital signal; and storing said binary compressed data in memory means.
