Abstract: An image generator generates brightness modulated bars for a video monitor. The bars run parallel to the scan line of the monitor allowing the use of a relatively slow digital to analog converter (DAC). A frame buffer need only be as deep as a number of different shades desired on a particular scan line, instead of needing to be as deep as the resolution of the DAC. Using a multiplexer allows use of a 1 bit deep frame buffer instead of a conventional 12 bit deep frame buffer. A feature of the image generator allows efficient determination of a mean gray scale used in generating the brightness modulated bars. The brightness modulation scheme is sinusoidal, that is, based on a sine function, for specified applications but can be any other modulation scheme based on, for example, a sawtooth function, a step function, an exponential function, and so forth.
