A stereo graphics system based on depth-based image rendering is disclosed. A master pipeline renders a first image from graphics data and derives a depth image relating to the first image. A rendering unit accesses the first image and the depth image from the master pipeline and renders a second image based on the first image and the depth image. First and second frame buffers retrieves and stores the first and second images, and a compositor accesses the first and second images from the frame buffers and combines the images to generate a resulting image.

An image capture apparatus includes an image sensor, a lens, an adjusting mechanism, and a controller. The image sensor is configured for detecting incident light to generate a corresponding captured image. The lens is configured for guiding light of a scene toward the image sensor. The adjusting mechanism is configured for adjusting a relative position relationship between the image sensor and the lens when the image capture apparatus is capturing the scene. The controller is configured for controlling the image sensor to generate a plurality of captured images of the scene in response to different relative position relationships between the image sensor and the lens.

Method and memory circuits capable of allowing M memory addresses of an N-port memory to be accessed concurrently, wherein N and M both are a natural number, and M is larger than N. Accordingly, a higher-order multi-port memory can be replaced by a lower-order multi-port or single-port memory. Consequently, smaller chip area or higher data access rate can be achieved.

A digital camera and an image capturing method for photographing at least one object in the digital camera. An image is sensed, and an eye-gazing detection process is accordingly preformed on the image to detect an eye-gazing direction of at least one pair of eyes of the at least one object. It is determined whether the eye-gazing direction meets a gazing criterion. If the eye-gazing direction meets the gazing criterion, an application of the digital camera is triggered.

An image capturing system comprises a storage device and a transcoder module coupled to the storage device. The storage device stores image data of a captured still image compressed by a first coding format configured. The transcoder module transcodes the image data compressed by the first coding format into output image data compressed by a second coding format and outputting the output image data to an external device when the external device requests the captured still image.

A method for performing parallel processing of at least two bins in an arithmetic coded bin stream includes: utilizing a current range to calculate a range for a first bin in the bin stream; simultaneously utilizing the current range to forward predict a plurality of possible ranges and low values for a second bin in the bin stream when the first bin is an MPS; when the range for the first bin is calculated, utilizing the calculated range to select a resultant range from the plurality of possible ranges and low values for the second bin.
摘要:
Sub-sampling pattern design for motion estimation in video compression. A motion estimation method divides a first frame into a plurality of macroblocks, performs block matching for a current macroblock pair on a candidate macroblock pair of a second frame. The current macroblock pair and the candidate macroblock pair are sampled according to a sub-sampling pattern, and an error measure between the current and candidate macroblock pairs is calculated. The sub-sampling pattern is constructed by a plurality of repeating units, and each repeating unit is composed of a first and a second pattern unit.
