Abstract
An adaptive color depth control may receive input signals from a power mode block, an ambient light sensor and/or a resource usage monitor to adjust the performance of a system through adaptation of the number of bits-per-pixel for each of the three primary colors supplied to a display. The spatial resolution may be adapted in a similar manner with inputs from the power mode block, ambient light sensor, and/or resource usage monitor.
Claims23
A circuit comprising:
- an adaptive color depth control block to adjust bandwidth of a bus coupled to an output of the circuit by changing a color depth for image data in response to a sensed input signal.
A circuit comprising:
- a power mode block to sense power consumption of the circuit;
- an ambient sensor to sense ambient lighting conditions for a user of the circuit;
- a resource usage monitor to sense activity of the circuit;
- and
- an adaptive color depth control block to change a color depth for an image data in response to at least one sensed signal from the power mode block, the ambient sensor and the resource usage monitor.
2 more elements
A method, comprising:
- reducing current in a microprocessor in a standby mode by reducing the resolution provided via a bus to a display;
- and
- adjusting bandwidth of data on the bus by changing a color depth for image data in response to a sensed signal.
A method, comprising:
- providing data to a display for displaying an image having a first resolution;
- placing a microprocessor in a standby mode;
- and
- reducing bandwidth of the data provided by the microprocessor to the display by providing data having a second resolution that is lower than the first resolution.
