Abstract:
1. A method comprising: providing a data selector means comprising a plurality of data inputs and a selector input, the data selector means adapted to select one of the data inputs based on the selector input and provide an output that corresponds to the selected data input; applying each bit of a multi-bit image signal to a corresponding data input; generating a data selector code at each of a rising and falling edge of a clock signal; concatenating an output of a multi-bit counter with an output of an inverter, wherein an input of the counter is coupled to the clock signal and wherein an input of the inverter is coupled to the clock signal and wherein the binary value of the counter comprises the three most significant bits of the data selector code and the value of the inverted clock signal comprises the least significant bit; applying the data selector code to the selector input; and coupling the output to a light-emitting element, wherein the output specifies any width of and interval between light pulses emitted by the light-emitting element.
