Dynamic image processing based on frequency of camera shutter activation

This disclosure pertains to techniques for dynamically adapting image capturing techniques, e.g., based on shutter activation frequency, to improve camera responsiveness. One such technique is a method, comprising: receiving a first capture request; in response to receiving the first capture request, using a first capturing technique to capture a first set of images based on an image capture sequence, the image capture sequence comprising one or more images; generating a first image based on the captured first set of images; receiving a second capture request within a first time window from the first capture request, wherein a duration of the first time window is based, at least in part, on a length of time needed to capture the one or more images of the image capture sequence using the first capturing technique; in response to the received second capture request, using a second capturing technique to capture a second set of images, wherein the second capturing technique is different from the first capturing technique; and generating a second image based on the captured second set of images.

Methods and apparatus for true high dynamic range imaging

When imaging bright objects, a conventional detector array can saturate, making it difficult to produce an image with a dynamic range that equals the scene's dynamic range. Conversely, a digital focal plane array (DFPA) with one or more m-bit counters can produce an image whose dynamic range is greater than the native dynamic range. In one example, the DFPA acquires a first image over a relatively brief integration period at a relatively low gain setting. The DFPA then acquires a second image over longer integration period and/or a higher gain setting. During this second integration period, counters may roll over, possibly several times, to capture a residue modulus 2.sup.m of the number of counts (as opposed to the actual number of counts). A processor in or coupled to the DFPA generates a high-dynamic range image based on the first image and the residues modulus 2.sup.m.

The dynamic range of a pixel is increased by using selective photosensor resets during a frame time of image capture at a timing depending on the light intensity that the pixel will be exposed to during the frame time. Pixels that will be exposed to high light intensity are reset later in the frame than pixels that will be exposed to lower light intensity.
