Patent ID: 7457461

Claim:
A video code device, comprising: an input to receive a serial stream of color pixel values; and an encoder to store a first one of said color pixel values, and to receive a current one of said color pixel values, wherein said encoder determines whether said current one of said color pixel values exceeds said first one of said color pixel values by less than a threshold and, if so, encodes said current pixel value by color match encoding, the encoder comprising: a threshold analyzer to receive the current one of said color pixel values; and a video compressor in communication with the threshold analyzer to communicate to the threshold analyzer the first one of said color pixel values comprising a previously identified one of said color pixel values in the stream of color pixel values; and wherein said threshold analyzer performs color space hysteresis on said current color pixel value to determine whether said current one of said color pixel values satisfies at least one of: (a) a predetermined positional relationship in a current or previous frame relative to said color pixel value standard, and (b) a predetermined positional relationship in a current run of pixels that includes another pixel having said predetermined positional relationship in a current or previous frame relative to said color pixel value standard.
