HIGH QUALITY UI ELEMENTS WITH FRAME EXTRAPOLATION
A frame processor may generate a mask based on one or more static regions of a first set of frames of a plurality of previous frame and adjust the mask to at least one of determine alpha data or conceal distorted content associated with the one or more static regions of the first set of frames. The distorted content may be caused by extrapolation of a frame from a second set of frames of the plurality of previous frames. The frame processor may generate a composite frame based on application of at least one of the mask or the alpha data to a previous frame of the plurality of frames, and application of the previous frame based on the at least one of the mask or the alpha data to the frame extrapolated from the second set of frames of the plurality of previous frames.
Method and system for producing streams of image frames
Methods, systems and computer program products, for producing streams of image frames. Image frames in streaming video are segmented into background segments and instance segments. A background image frame containing the background segments is created. At least some of the instance segments are classified into movable objects of interest and movable objects of non-interest. During a background update time period, the background image frame is updated when a movable object of non-interest has moved to reveal a background area, to include the revealed background area in the background image frame. A foreground image containing the movable objects of interest is created. Blocks of pixels of the updated background and foreground image frames are encoded. A stream of encoded foreground image frames having a first frame rate is produced. A stream of encoded updated background image frames a second, lower frame rate is produced.

Imaging apparatus, control method of imaging apparatus, and non-transitory storage medium storing control program of imaging apparatus
An imaging apparatus includes a reading unit, a display unit, and a control unit. The reading unit reads pixel signals from imaging pixels and focus detection pixels. The display unit displays an image. When both exposure/reading of the imaging pixels and the focus detection pixels are achievable within time corresponding to a display frame rate of the display unit, the control unit controls to alternate the exposure/reading of the imaging pixels and the exposure/reading of the focus detection pixels. When both the exposure/reading of imaging pixels and the focus detection pixels are not achievable within the time, the control unit controls to perform the exposure of the imaging pixels and the focus detection pixels at the same time and read the pixel signals of the imaging pixels and the focus detection pixels after the end of the exposure of the imaging pixels and the focus detection pixels.

CONVERTING DUAL-CONTEXT VIDEO DATA TO FULL COLOR VIDEO
Systems and methods are provided for generating color video from a dual-context camera. A dual-context camera provides a first series of video frames encoded in accordance with a full color model and a second series of video frames encoded in accordance with an underdetermined color model. The two series of video frames are interleaved as to form a series of pairs of frames, each comprising a color video frame and an underdetermined video frame. An image merger generates a composite image for each pair of frames in the series of frames. The composite image includes a set of brightness values from the underdetermined video frame and a set of chrominance values from the color video frame. A color video source replaces the underdetermined image in each of the series of pairs of frames with the composite image generated for the pair of frames to provide a color video stream.
