Abstract: The method includes in order to generate a composite image: identifying, in the frame of a video stream captured by a camera, a motion characteristic associated with moving objects in a scene while the camera captured a sliding window of the video stream. The method includes for a plurality of frames in the sliding window: controlling, by the processing circuitry, a weight of blending of the frame based on the identified motion characteristic to enable the composite image to be generated according to the controlled weights of blending of the plurality of frames in the sliding window.

Abstract: A method for dynamic calibration correction in multi-frame, multi-exposure capture in a camera system includes receiving an amplified non-reference frame (e.g., with non-standard exposure value EV-4) to which a digital gain was applied and a reference frame (e.g., with standard exposure value EV0). The method includes generating a mask based on the reference frame and the amplified non-reference frame. The method includes estimating a scaling coefficient and an offset coefficient for each of a number of channels in the amplified non-reference frame, based on selected pixel locations in the generated mask. The method includes correcting a calibration of the amplified non-reference frame by applying the scaling coefficients for each of the channels. The method also includes outputting a calibration-corrected amplified non-reference frame to a multi-frame processor.

Abstract: A method includes receiving a reference input frame and a non-reference input frame; separating a luma plane for a luma channel and a chroma plane for a chroma channel for each of the reference input frame and the non-reference input frame; generating a luma frame using the luma plane; generating a chroma frame using the chroma plane in a patch-based chroma blending; and combining the luma frame and the chroma frame into an output frame.

Abstract: A method of capturing a photo using a mobile device is described. The method comprises detecting a signature motion of the mobile device; capturing video using a camera of the mobile device upon detecting the signature motion; and automatically identifying a start frame and an end frame of the captured images using neural networks. A mobile device for capturing a photo is also described.
