Abstract:

In visual psychophysics it is sometimes necessary to be able to display Luminances with 12 bit precision. This report describes a method where two 8 bit color outputs of a DeAnza IP8400 image processor are combined into a monochrome signal with an effective resolution of 12 bits. The implementation in hardware and software, and the calibration of the system are described. Measurements show that the system meets the desired specifications. Contrast, Resolution, Monitor Calibration.
