Patent ID: 7590330

Claim:
A computer readable medium having stored thereon bitmap data and a software program to be readout and executed by a computer for processing the bitmap data to control a display of the bitmap data to produce a horizontal motion of an object wherein the bitmap data comprises run-length coded combined pixels in a data area; and wherein the software program comprise sequences of control instructions comprising address pointers that determine where in said data area the computer will start a run-length decoding; wherein the combined pixels comprise a combination of values of pairs of corresponding pixels from horizontally neighboring equal-sized segments of a picture sequence and have a unique type corresponding to the distribution of the pixel values in the pair of corresponding pixels; and wherein the runlength coded combined pixels comprise groups of a predetermined number of combined pixels, each run-length coded separately, and wherein said predetermined number of combined pixels has been set as a number of pixels by which the object is to be moved per movement step in the horizontal motion.
