Patent ID: 8456494

Claim:
A method for automated generation of an optimized bit sequence used in pulse width modulation (PWM) to create intermediate light intensity levels on spatial light modulation (SLM) display systems, the method comprising: providing a table of pluralities of choices of potential specific bit sequences for use for respectively creating corresponding ones of the intermediate light intensity levels; providing inputs influencing selection of the potential bit sequences for a particular image frame displayed by the SLM display system; developing variables based on the inputs, the variables providing information regarding PWM artifacts created by each potential bit sequence for the particular image frame; creating constraint equations based at least in part on the variables, the constraint equations limiting the potential bit sequences to viable bit sequences that the SLM display system can perform and/or that satisfy user-defined rules; creating at least one objective function based at least in part on the variables, the objective functions evaluating the effectiveness of the viable bit sequences in minimizing PWM artifacts for the particular image frame; and generating an optimum bit sequence using a potential bit sequence selected from the table from among the viable bit sequences based on the constraint equations and objective functions, the optimum bit sequence having minimized PWM artifacts for the particular image frame.
