Temporal fallback for high frame rate picture rate conversion

摘要

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.
