Abstract: Temporal filtering operations may be reset for certain pixels within an image frame to reduce contribution from previous input frames to reduce ghosting and other artifacts. The resetting reduces the contribution to, for example, zero, either immediately or within a predetermined period of time (e.g., a certain number of frames). A decision regarding whether to reset temporal filtering for a pixel of the image frame may be based on a probability assigned to that pixel. The probability can be based on rules with one or more criteria. One example factor for adjusting probability is a confidence level regarding the temporal filtering decision for the pixel, in which the probability for a random reset of a pixel is based on the confidence level regarding the temporal filtering decision for those pixels.

Abstract: Techniques and systems are provided for processing one or more frames or images. For instance, a process for determining exposure for one or more frames includes obtaining a motion map for one or more frames. The process includes determining, based on the motion map, motion associated with the one or more frames of a scene. The motion corresponds to movement of one or more objects in the scene relative to a camera used to capture the one or more frames. The process includes determining, based on the determined motion, a number of frames and an exposure for capturing the number of frames. The process further includes sending a request to capture the number of frames using the determined exposure duration.

Abstract: In general, techniques are described regarding generating, based on zoom settings, various sets of frames of image data (e.g., video data). Cameras comprising one or more camera processors configured to perform the techniques are also disclosed. The camera processor(s) receive a plurality of frames of image data. The camera processor(s) receive, via a user interface, a zoom setting for each of the plurality of frames. The camera processor(s) may generate a first set of frames according to the zoom settings. The camera processor(s) determine a second set of frames, where the second set of frames are different from the first set of frames. The second set of frames may comprise a second zoom that is different than a first zoom applied to the first set of frames.

Abstract: In general, techniques are described regarding selective allocation of processing resources for processing image data. Processing circuitry may warp a frame of image data around variously indicated areas of the frame to create a warped frame of image data. The processing circuitry may allocate more pixels to the indicated areas by virtue of the frame warping operation. The warped frame may then be output for further processing in accordance with proportions of the warped frame resulting in better image or video quality in the indicated areas.
