Device and method for processing image array data, and color table generation method thereof

A method for processing image array data, comprising:

• providing an image array data, including a plurality of first blocks, detected by a sensor at a first time point, wherein each of the first blocks comprises a color table corresponding thereto;
• segmenting an image array data detected by the sensor at a second time point into a plurality of second blocks;
• comparing an image array data of each of the second blocks with an image array data of each of the first blocks to generate a numerical difference information;
• and
• allocating the color tables corresponding to the first blocks to the second blocks matching the first blocks according to the numerical difference information.

A color table generation method, comprising:

• arranging a plurality of color codes by a first order according to a color change of the color codes to form a first section;
• arranging the color codes by a second order contrary to the first order to form a second section;
• and
• alternately and repeatedly arranging the first section and the second section to form a color table with infinite length.
