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.
Claims17
An apparatus comprising:
- a Picture Rate Conversion (PRC) controller configured to output a stream of images at an adjustable temporal rate, wherein the adjustable temporal rate is constrained within a range defined by a first predetermined rate and a second predetermined rate;
- a system resource monitor configured to obtain a measurement of system CPU resource utilization;
- and
- a PRC setting calculator coupled to the system resource monitor and to the PRC controller, the PRC setting calculator configured to determine a setting for the PRC controller, wherein the setting is calculated in response to the measurement of system CPU resource utilization;
- wherein the PRC controller is further configured to determine a value for the adjustable temporal rate based on the setting;
- and
- wherein the system resource monitor comprises a system resource estimator configured to generate an estimate of available system CPU resources, wherein the measurement of system CPU resources utilization comprises the estimate of available system CPU resources.
A system comprising:
- an image source configured to supply a first stream of images;
- an image controller in communication with the image source, the image controller comprising:
- a Picture Rate Conversion (PRC) controller configured to output a second stream of images at an adjustable temporal rate, wherein the adjustable temporal rate is constrained within a range defined by a first predetermined rate and a second predetermined rate;
- a system resource monitor configured to obtain a measurement of system CPU resource utilization;
- and
- a PRC setting calculator coupled to the system resource monitor and to the PRC controller, the PRC setting calculator configured to determine a setting for the PRC controller, wherein the setting is calculate base on the measurement of system CPU resource utilization;
- wherein the PRC controller is further configured to determine a value for the adjustable temporal rate based on the setting;
- wherein the system resource monitor comprises a system resource estimator configured to generate an estimate of available system CPU resources, wherein the measurement of system CPU resource utilization comprises the estimate of available system CPU resources;
- and
- an image display panel in communication with the image controller, the image display panel configured to display the second steam of images at the adjustable temporal rate.
A method comprising:
- obtaining a measure of system CPU resource utilization;
- determining a setting corresponding to an adjustable temporal rate, wherein the setting is calculated based on the measurement of CPU resource utilization;
- wherein the measurement of system CPU resource utilization comprises an estimate of available system CPU resources;
- and
- outputting a stream of images at the adjustable temporal rate in response to the setting, wherein the adjustable temporal rate is constrained within a range defined by a first predetermined rate and a second predetermined rate.
