Image processing method for facilitating data transmission
View Patent ↗An image processing method for facilitating data transmission is provided. An image compression method is performed to convert X-bits binary digital signals to a binary compressed data in a floating-point form of (1.n)*2 m . Bit m represents the first bit with logic level “1” of the X-bits binary digital signals, and n represents the bits taken from the X-bits binary digital signals after the bit m. The 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). The latter n bits of the sequence of binary numbers are consisted of the n bits of the X-bits digital signal. Therefore, by the present image compression method, the transmission amount of image data is reduced. The transmission time of image data and the volume of a memory for storing the image data are also reduced.
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.
2. The method of claim 1 , wherein further comprising accessing said binary compressed data from memory means by imaging processing means to a host for decompressing said binary compressed data to recover said X-bits binary digital signals.
3. The method of claim 2 , wherein said step for decompressing said binary compressed data comprises:
(a) converting the bits of said binary compressed data before said latter n bits of said binary compressed data to the value of m; and
(b) recovering said binary compressed data to said X-bits binary digital signals in accordance with said n bits, the value of m and the algorithm form of (1.n)*2 m .
4. The method of claim 3 , further comprising a step for compensating the pixel corresponding to said X-bits binary digital signals with a bit-enhanced method after the step (b), wherein said bit-enhanced method comprises (c) calculating a first average of a plurality of neighboring pixels around the pixel; and (d) calculating a second average of the first average and the pixel.
5. The method of claim 1 , further comprising accessing said binary compressed data from memory means by host for decompressing said binary compressed data to recover said X-bits binary digital signals.
6. The method of claim 5 , wherein said step for decompressing said binary compressed data comprises:
(a) converting the bits of said binary compressed data before said latter n bits of said binary compressed data to the value of m; and
(b) recovering said binary compressed data to said X-bits binary digital signals in accordance with said n bits, the value of m and the algorithm form of (1.n)*2 m .
7. The method of claim 6 , further comprising a step for compensating the pixel corresponding to said X-bits binary digital signals with a bit-enhanced method after the step (b), wherein said bit-enhanced method comprises (c) calculating a first average of a plurality of neighboring pixels around the pixel; and (d) calculating a second average of the first average and the pixel.
