Abstract
An association circuit determines whether a first pixel in an image will be associated with an entry in a palette, based on a threshold for a difference between a pixel value and a palette value. An addition circuit adds an entry to the palette when the first pixel is not associated with an entry. A fusion circuit fuses two entries so as to generate a fused entry when a condition of a target amount of information is not satisfied by adding an entry. A control circuit changes the threshold when the first pixel is associated with an entry, when an entry is added, or when the fused entry is generated and an entry is added. The association circuit determines whether a second pixel in the image will be associated with an entry, based on the changed threshold. A palette encoding circuit encodes the image by using the palette.
