20080252345 | SYSTEM AND METHOD FOR GENERATING A RESET SIGNAL - Systems and methods are provided to generate a reset signal, such as to facilitate synchronization. In one embodiment, a system to generate a reset signal includes an offset generator that provides an offset clock signal having a frequency offset relative to a frequency of an input clock signal. A reset generator generates the reset signal in response to detecting a periodic phase shift between the offset clock signal and the input clock signal. | 10-16-2008 |
20090190036 | VIDEO PROCESSING SYSTEM PROVIDING INTERLACED VIDEO FIELD INVERSION DETECTION FEATURES AND RELATED METHODS - A video processing system may include an input for receiving interlaced video data arranged in successive frames each including odd and even fields. A processor may be coupled to the input for determining an improper inversion of the odd and even fields based upon a pair(s) of successive first and second frames each including successive first and second fields. The processor may generate a first difference value(s) based upon a comparison between the first field in the first frame and the second field in the second frame, and a second difference value(s) based upon a comparison between a second field in the first frame and the first field in the second frame. The processor may determine an improper inversion of the odd and even fields based upon a comparison of the first difference value(s) and the second difference value(s) for the pair(s) of successive first and second frames. | 07-30-2009 |
20090195658 | VIDEO PROCESSING SYSTEM PROVIDING IMAGE PATTERN DETECTION BASED UPON IMAGE TRANSITION BOUNDARIES AND RELATED METHODS - A video processing system may include an input for receiving video data including video signal values for a corresponding plurality of image pixels and having an image pattern therein. The system may further include a processor coupled to the input for determining a series of video signal value differences for each pair of adjacent image pixels along at least one direction, detecting at least one image transition boundary based upon the series of video signal value differences, and detecting the image pattern based upon the at least one image transition boundary. | 08-06-2009 |
20100231763 | DEFECTIVE PIXEL DETECTOR FOR A DIGITAL VIDEO CAMERA AND ASSOCIATED METHODS - A defective pixel tester determines defective pixels within a digital video camera. The tester includes a video input, a memory and a controller. The video input receives video frames from the digital video camera, with each video frame defined by a plurality of pixel values. The memory stores captured video frames and pixel test results. The controller generates difference values for corresponding pixel values from different video frames, generates pixel test results based upon a comparison of the difference values to a threshold, and stores the pixel test results in the memory. | 09-16-2010 |
20120057712 | MULTI-CHANNEL AUDIO DISPLAY - An audio display system can include an audio input configured to receive a plurality of inputs corresponding different audio channels of a multi-channel audio signal. A phase calculator is configured to determine a relative phase between at least a given pair of the audio channels. An amplitude calculator is configured to determine an amplitude for at least the given pair of audio channels. A display generator is configured to generate an audio display. The audio display can include an amplitude element representing the amplitude determined for each audio channel in the given pair of the audio channels, the amplitude elements being spaced apart from each other to define a phase zone between the respective pair of amplitude elements. The audio display can also include a phase output plotted in the phase zone between the respective pair of amplitude elements, the phase output representing a phase relationship between the given pair of the audio channels. | 03-08-2012 |
