    摘要: The present disclosure provides techniques relates to the implementation of a raw pixel processing unit using a set of line buffers. In one embodiment, the set of line buffers may include a first subset and second subset. Various logical units of the raw pixel processing unit may be implemented using the first and second subsets of line buffers in a shared manner. For instance, in one embodiment, defective pixel correction and detection logic may be implemented using the first subset of line buffers. The second subset of line buffers may be used to implement lens shading correction logic, gain, offset, and clamping logic, and demosaicing logic. Further, noise reduction may also be implemented using at least a portion of each of the first and second subsets of line buffers.

    摘要: A system and method is disclosed for efficiently managing power distribution among the various functional blocks used within portable electronic devices. The method includes allowing each functional block to be independently controlled, containing its own low-level software and power controls for setting the local power state of the functional block. For each power control domain in the implementation, hardware uses these local power states and determines and sets the actual operating state of the power control domain accordingly.

    摘要: Systems and methods for correcting geometric distortion are provided. In one example, an electronic device may include an imaging device, which may obtain image data of a first resolution, and geometric distortion and scaling logic. The imaging device may include a sensor and a lens that causes some geometric distortion in the image data. The geometric distortion correction and scaling logic may scale and correct for geometric distortion in the image data by determining first pixel coordinates in uncorrected or partially corrected image data that, when resampled, would produce corrected output image data at second pixel coordinates. The geometric distortion correction and scaling logic may resample pixels around the image data at the first pixel coordinates to obtain the corrected output image data at the second pixel coordinates. The corrected output image data may be of a second resolution.

    摘要: A display pipe may include a video pipe outputting pixels of a video stream in a first color space, e.g. YCbCr color space. The display pipe may also include a first color space converter to convert the output pixels to a second color space, e.g. to RGB color space, producing a conversion output in which some of the converted output pixels have values that are invalid pixel values in the second color space. The display pipe may also include a blend unit that performs blending operations in the second color space on the converted output pixels to produce a blended conversion output that includes blended pixels in the second color space. A second color space converter in the display pipe may convert the blended pixels from the second color space to the first color space, and correctly display the converted blended pixels on a display screen.
