摘要： Various schemes pertaining to generating an output image using hybrid motion-compensated fusion techniques are described. An apparatus receives multi-frame data comprising a plurality of images consecutively captured. The apparatus subsequently generates a first intermediate image and a second intermediate image by performing temporal fusion on a first part and a second part of the multi-frame data, respectively. The apparatus further generates the output image using motion-compensated fusion based on the first and second intermediate images. The apparatus provides benefits of efficiently reducing noise and blurriness in the output image.

摘要： A processor or control circuit of an apparatus receives data of an image based on sensing by one or more image sensors. The processor or control circuit also detects a region of interest (ROI) in the image. The processor or control circuit then adaptively controls a light projector with respect to projecting light toward the ROI.

摘要： An electronic apparatus is provided. The electronic apparatus includes a display device, a sensor, and a processor. The display device receives an image data. The display device includes a display panel and displays an image related to the image data on the display panel. A reference image point of the image is displayed on a first location on the display panel. The sensor detects a movement status of the electronic apparatus when the electronic apparatus shakes to generate at least one movement parameter. The processor calculates compensation data according to the at least one movement parameter and size information of the display panel. When the display device receives the compensation data, the display device displays the image by shifting the reference image point of the image from the first location to a second location on the display panel to display according to the compensation data.

摘要： Various schemes pertaining to generating a full-frame color image using a hybrid sensor are described. An apparatus receives sensor data from the hybrid sensor, wherein the sensor data includes partial-frame chromatic data of a plurality of chromatic channels and partial-frame color-insensitive data. The apparatus subsequently generates full-frame color-insensitive data based on the partial-frame color-insensitive data. The apparatus subsequently generates the full-frame color image based on the full-frame color-insensitive data and the partial-frame chromatic data. The apparatus provides benefits of enhancing image quality of the full-frame color image especially under low light conditions.

摘要： Various examples with respect to adaptive infrared (IR) projection control for depth estimation in computer vision are described. A processor or control circuit of an apparatus receives data of an image based on sensing by one or more image sensors. The processor or control circuit also detects a region of interest (ROI) in the image. The processor or control circuit then adaptively controls a light projector with respect to projecting light toward the ROI.

摘要： Video decoding device is disclosed. The video decoding device comprises a demultiplexer, a first decoder and a controller. The demultiplexer receives a Transport Stream to recover video Packetized Elementary Stream (PES) to determine a presentation time stamp (PTS) and a decoding time stamp (DTS) in a PES header of the PES. The first decoder retrieves a video frame from the video PES to determine temporal reference of the video frame. The controller receives the PTS, the DTS, and the temporal reference to determine whether there is a missing video frame.

摘要： Methods and apparatuses pertaining to adaptive display partial update may involve determining whether partial update for an image frame is allowed and, responsive to a determination that the partial update for the image frame is allowed, determining whether the partial update is applicable to the image frame. Responsive to a determination that the partial update is applicable to the image frame, whether or not at least a difference between one or more properties of the image frame and one or more properties of a previous image frame exceeds a threshold may be determined. A partial-frame processing may be performed to partially update the image frame responsive to a determination that the difference does not exceed the threshold.
