摘要： An imaging system that has an image processing function and is capable of generating an interpolation image is provided. The imaging system has an additional function such as image processing and can generate an interpolation image by using image data output from an imaging device. The imaging device can perform filter processing in parallel during a light exposure period, and thus can perform a large amount of arithmetic operation and generate a high-quality interpolation image. The number of arithmetic operations can be further increased particularly during image capturing in a dark place, which requires a long exposure time. Accordingly, the frame rate can be substantially increased, and high-quality moving image data can be generated.

摘要： Methods and apparatuses to encode both high dynamic range images and low dynamic range images. The input video may also convert the high dynamic range image to an image of lower luminance dynamic range by applying either a scaling the high dynamic range image to a predetermined scale of the luma axis or by applying a sensitivity tone mapping which changes the brightnesses of pixel colors falling within a subrange or by applying a gamma function or by applying an arbitrary monotonically increasing function mapping the lumas.

摘要： A method comprising: receiving a high frame rate video stream of a scene, wherein the scene comprises at least one object in motion relative to an imaging device acquiring the video stream; continuously dividing, in real time, the video stream into at least one consecutive sequences of n frames each; with respect to each current sequence: (i) estimating pixel motion between at least some pairs of frames in the sequence, (ii) calculating a motion vector field for each pixel in the sequence, (iii) generating a representative frame which co-locates all of the pixels to respective pixel positions, based on the calculated motion vector fields, and (iv) aggregating, for each of the respective pixel positions, pixel values from all frames in the sequence; and outputting, in real time, a stream of the representative frames, wherein the stream has a lower frame rate than the high frame rate.

摘要： Dynamic transcode throttling methods and devices for processing resource management and thermal mitigation in electronic devices such as eyewear devices. An electronic device monitors its temperature and, responsive to the temperature, configures a transcoding service to operate at different rates. A frame delay module is configured to add a delay between read frames prior to the transcoding service. This enables the electronic device to consume less power when temperatures are too high in order to provide thermal mitigation and can be performed without powering down the electronic device.
