Abstract: A method and apparatus for a digital video display. A digital display device receives an analog signal representing an image formed of pixels in video lines and a signal containing a synchronization waveform for the image. An analog-to-digital converter (ADC) receives the analog signal and converts it to a sampled digital waveform. A phase-locked loop including a programmable frequency divider controls the sampling time for the ADC. The programmable frequency divider is controlled by a dividing-ratio algorithm that selects a dividing ratio, measures the number of pixels in a video line using the dividing ratio, and recomputes the dividing ratio by multiplying the selected dividing ratio by the expected number of pixels in a video line and dividing by the measured number of pixels. The sampling phase for the ADC is selected by a sampling-phase control algorithm that minimizes a function representative of the flatness of the sampled digital waveform.

Abstract: Count rates may be obtained from one or more subpixels for a given pixel in an imaging system detector. Count rates may be obtained from individual subpixels, or may be from electronically binned subpixels at least in part in various subpixel arrangements where a selected subpixel arrangement may be adaptively set according to a detected count rate. For lower count rates, two or more subpixels may be electronically binned together and the counts may be obtained from the binned subpixels, for example to mitigate a charge sharing effect. For higher count rates, the count rates of a greater number of subpixels may be individually obtained, for example to mitigate a pulse pile-up effect. Detective quantum efficiency may be optimized over a wider range of photon flux rate via the adaptive subpixel arrangement.
