  • Temporal fallback for high frame rate picture rate conversion
    Patent number: 8804044
    Abstract: An apparatus to provide a fall-back procedure for a PRC imaging device is described. The apparatus includes a PRC controller, a system resource monitor, and a PRC setting calculator. The PRC controller outputs a stream of images at an adjustable temporal rate. The adjustable temporal rate is constrained within a range defined by a first predetermined rate and a second predetermined rate. The system resource monitor obtains a measurement of system resource utilization. The PRC setting calculator determines a setting for the PRC controller in response to the measurement of system resource utilization. Additionally, the PRC controller determines a value for the adjustable temporal rate in response to the setting.

  • MOTION-COMPENSATED PROCESSING OF IMAGE SIGNALS
    Publication number: 20090279609
    Abstract: In a motion-compensated processing of images, input images are down-scaled (scl) to obtain down-scaled images, the down-scaled images are subjected to motion-compensated processing (ME UPC) to obtain motion-compensated images, the motion-compensated images are up-scaled (sc2) to obtain up-scaled motion-compensated images; and the up-scaled motion-compensated images are combined (M) with the input images to obtain output images.
