USING A GRAPHICS PROCESSING UNIT TO CORRECT VIDEO AND AUDIO DATA
First Claim
1. A device comprising:
- an image capture device comprising an array of detector elements that generates a corresponding first plurality of pixel values comprising a first frame of image data;
a memory operable to store said first plurality of pixel values;
a display device operable to display an image based on said first plurality of pixel values; and
a graphics processing unit (GPU) operable to execute a method of processing said first plurality of pixel values, said method comprising;
identifying an unacceptable pixel value, wherein said unacceptable pixel value is considered unacceptable if a criterion is satisfied; and
determining a new value for said unacceptable pixel value.

Abstract
Described is a device (e.g., a cell phone incorporating a digital camera) that incorporates a graphics processing unit (GPU) to process image data in order to increase the quality of a rendered image. The processing power provided by a GPU means that, for example, an unacceptable pixel value (e.g., a pixel value associated with a malfunctioning or dead detector element) can be identified and replaced with a new value that is determined by averaging other pixel values. Also, for example, the device can be calibrated against benchmark data to generate correction factors for each detector element. The correction factors can be applied to the image data on a per-pixel basis. If the device is also adapted to record and/or play digital audio files, the audio performance of the device can be calibrated to determine correction factors for a range of audio frequencies.
