Abstract: 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.

Abstract: An image signal amplifying circuit comprising an amplifier and a gain control circuit. The amplifier respectively amplifies a first image signal and a second image signal, which are generated by a pixel array of an image sensor, by a first analog gain and a second analog gain, wherein each one of pixel circuits of the pixel array comprises a first capacitor for generating the first image signal and a second capacitor for generating the second image signal, wherein a charge storage capacity of the first capacitor is smaller than a charge storage capacity of the second capacitor. The gain control circuit selectively adjusts the first analog gain or the second analog gain. Each one of the pixel circuits has a first conversion gain corresponding to the first capacitor and a second conversion gain corresponding to the second capacitor.

Abstract: 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.

Abstract: 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.

Abstract: Aspects of the disclosure provide a method for merging compressed access units according to compression rates and/or positions of the respective compressed access units. The method can include receiving a sequence of compressed access units corresponding to a sequence of raw access units partitioned from an image or a video frame and corresponding to a sequence of memory spaces in a frame buffer, determining a merged access unit including at least two consecutive compressed access units based on compression rates and/or positions of the sequence of compressed access units. The merged access unit is to be stored in the frame buffer with a reduced gap between the at least two consecutive compressed access units compared with storing the at least two consecutive compressed access units in corresponding memory spaces in the sequence of memory spaces.

Abstract: A method and apparatus for video encoding to generate a partitioned bitstream without buffering transform coefficient and/or prediction data for subsequent coding units are disclosed. An encoder incorporating an embodiment according to the present invention receives first video parameters associated with a current coding unit, wherein no first video parameters associated with subsequent coding units are buffered. The encoder then encodes the first video parameters to generate a current first compressed data corresponding to the current coding unit. A first memory address in the first logic unit is determined and the encoder provides the current first compressed data at the first memory address in the first logic unit.

Abstract: Method and system of video decoding incorporating frame compression to reduce frame buffer size are disclosed. The method adjusts parameters of the frame compression according to decoder system information or syntax element in the video bitstream. The decoder system information may be selected from a group consisting of system status, system parameter and a combination of system status and system parameter. The decoder system information may include system bandwidth, frame buffer size, frame buffer status, system power consumption, and system processing load. The syntax element comprises reference frame indicator, initial picture QP (quantization parameter), picture type, and picture size. The adaptive frame compression may be applied to adjust compression ratio. Furthermore, the adaptive frame compression may be applied to a decoder for a scalable video coding system or a multi-layer video coding system.
