  • Patent number: 11812165
    Abstract: A video capture method includes: controlling an image sensor to capture a plurality of first sensor output frames at a first frame rate during a first period; during the first period, checking if a motion blur condition is met; in response to the motion blur condition being met during the first period, controlling the image sensor to capture a plurality of second sensor output frames at a second frame rate during a second period following the first period, wherein the second frame rate is higher than the first frame rate; and processing consecutive sensor output frames captured by the image sensor during the first period and the second period, to generate a plurality of output frames.

  • Publication number: 20230260081
    Abstract: An image processing method is provided. The image processing method is applied to an image signal processor. The image processing method includes the stages detailed in the following paragraph. Binned-Bayer raw data and binned-white raw data are received from an image sensor with an RGBW color filter array. The binned-Bayer raw data include information of red, green, and blue channels for a plurality of pixels. The binned-white raw data include luminance information for the pixels. The pixels are rendered based on both the binned-Bayer raw data and the binned-white raw data.

  • Publication number: 20200294193
    Abstract: Various examples pertaining to utilization of a resizer in image processing are described. A processor of an apparatus receives image data of a captured image from an image sensor. The processor processes the image data through a pipeline in which the image data is resized before further processing is performed to provide processed data of a processed image used in preview or video recording.

  • Publication number: 20180357750
    Abstract: A demosaicking method for an image having a multi-cell mosaic pattern, wherein the multi-cell mosaic pattern includes a first quarter, a second quarter, a third quarter, and a fourth quarter. Each quarter includes multiple cells, and each cell includes a pixel value. The method includes: obtaining the image; performing an image-dividing process on the image to obtain four Bayer plane images; performing a quarter-resolution demosaicking process on each of the four quarter-resolution plane images to obtain a quarter-resolution image in each color channel; and performing an image-combining process on the quarter-resolution image in each color channel to generate a first full-resolution image in each color channel.

  • Patent number: 8427476
    Abstract: A display system for improving visual comfort and a method of adaptively adjusting resolution of a display device are provided. The display system includes a display device, a memory, an image sensor, a face recognition unit, a distance detection unit, and a controller. The memory stores face representation data and user preference data. The image sensor captures an image and converts it into an electrical signal. The face recognition unit analyzes that electrical signal to recognize a face image and compares the recognized face image with the face representation data to generate a first signal. The distance detection unit analyzes the electrical signal to determine a distance between the display device and the user to generate a second signal. The controller then generates a parameter based on the first signal and the second signal and adjusts a display resolution of the display device based on the parameter.

  • Publication number: 20110141114
    Abstract: A display system for improving visual comfort and a method of adaptively adjusting resolution of a display device are provided. The display system includes a display device, a memory, an image sensor, a face recognition unit, a distance detection unit, and a controller. The memory is configured to store face representation data and user preference data. The image sensor is positioned with respect to the display device for capturing an image and converting the image into an electrical signal. The face recognition unit is configured to analyze the electrical signal to recognize a face image of a user and comparing the recognized face image with the face representation data to generate a first signal. The distance detection unit is configured to analyze the electrical signal to determine a distance between the display device and the user to generate a second signal.
