Abstract
A system and method for improving image processing. In one aspect of the invention the method includes receiving data indicating an intensity of light incident on a first pixel of a pixel array and determining from the received data if the intensity of incident light on the first pixel satisfies a first condition. A processing operation is performed on data received from a second, third and fourth pixel of the pixel array but skipped on the data received from the first pixel if the first condition is satisfied. The first condition includes whether the first pixel is substantially saturated in response to an intensity of light incident on the first pixel.
Claims22
A method, comprising:
- receiving data indicating an intensity of light incident on a first pixel of a pixel array;
- determining from the received data if the intensity of light incident on the first pixel satisfies a first condition;
- and
- performing a processing operation on data received from a second, third and fourth pixel of the pixel array but skipping the data processing operation on the data received from the first pixel if the first condition is satisfied.
An apparatus, comprising:
- an image sensor including a first, second, third and fourth pixel arranged in an array;
- a digital signal processor coupled to the image sensor, the digital signal processor comprising:
- a memory to have stored therein information received from the first, second, third and fourth pixel of the array, and
- a processor coupled to the memory to perform a processing operation on information received at the array, wherein the processing operation is performed on information received from the first pixel if an intensity of light received at the first pixel is below a saturation threshold for the first pixel, wherein the processing operation is not performed on information received from the first pixel if the intensity of the light received from the first pixel crosses the saturation threshold.
A method, comprising:
- sampling a first pixel using a first integration time, the first pixel to receive incident white light;
- adjusting the first integration time to select a second integration time;
- the selection of the second integration time based on the sampling of the first pixel using the first integration time;
- and
- sampling substantially each of the pixels of a pixel array including the first pixel using the second integration time.
