Abstract: An encoding method and an encoder are provided. The encoding method includes receiving a first coding unit of a frame, and selecting a first index pixel and a second index pixel from pixels of the frame and setting index values corresponding to the two index pixels, where a color of the first index pixel is different to a color of the second index pixel. The encoding method includes indexing each pixel in the first coding unit to generate an index map. The encoding method includes generating a coding value corresponding to the first coding unit according to the index map, and transmitting the coding value to a decoder, wherein only an index value corresponding to a 1st scanned pixel in the pixels of the first coding unit in the index map is recorded in the coding value.

Abstract: In an embodiment, an encoding method includes generating a histogram corresponding to all pixels in a coding unit. The encoding method further includes seeking a first color value according to the histogram, wherein a first number of pixels of the first color value in the histogram is greater than or equals to a first threshold. The encoding method further includes seeking a second color value in a first range of the first color value according to the histogram. The encoding method further includes removing one or more pixels of the first color value from the histogram when a second number of pixels of the second color value is greater than or equals to a second threshold. The encoding method further includes adding the first color value into an initial color table when the second number of pixels is less than the second threshold. An encoder is also provided in the disclosure.
