Abstract

A camera image sensor captures image data at a first rate, and stores the captured image data at a DSP buffer until it is processed by a DSP image processor. In response to the available capacity at the DSP buffer falling below a first threshold, the DSP buffer notifies the image sensor of the buffer's status, and the image sensor is configured to capture image data at a second rate. The second rate can be associated with a frame rate lower than the frame rate associated with the first rate, and/or can be associated with a resolution less than the resolution associated with the first rate. When the available capacity of the DSP increases, for instance, above a second threshold, the image sensor can be re-configured to capture image data at the first rate, or at a third rate different from the second rate and first rate.
