Abstract: An image sensor, system and method that alternates sub-sets of pixels with long exposure times and pixels with short exposure times on the same sensor to provide a sensor having improved Wide Dynamic Range (WDR). The sub-sets of pixels are reset at different time intervals after being read, which causes the respective integration times to vary. By combining information contained in the both the short and long integration pixels, the dynamic range of the sensor is improved.

Abstract: A method, apparatus and system are described providing a high dynamic range pixel. An integration period has multiple sub-integration periods during which charges are accumulated in a photosensor and repeatedly transferred to a storage node, where the charges are accumulated for later transfer to another storage node for output.
Abstract: A method, apparatus and system that allows for the identification of defective pixels, for example, defective pixel clusters, in an imager device. The method, apparatus and system determine, during use of the imager device, that a pixel defect, e.g., cluster defect, exists and accurately maps the location of the defective pixel. By analyzing more than one frame of an image, the method increases the accuracy of the defect mapping, which is used to improve the quality of the resulting image data.

An edge detecting unit is configured to detect edge components from an image signal obtained by the image pickup device and to output detection levels of the detected edge components. A color signal replacement unit is configured to replace a signal of a pixel corresponding to the detection level with a predetermined color signal when the detection level satisfies a predetermined condition. A display unit is configured to display an image based on an output image signal from the color signal replacement unit.

Based on a detection result, the imaging apparatus adjusts the level of the audio signal and outputs the adjusted audio signal. When the driving portion is not driven, the imaging apparatus adjusts the level of the audio signal after adjustment to be lower as the level of the detection result is lower. When the driving portion is driven, the imaging apparatus sets the level of the audio signal after adjustment to be lower than that when the driving portion is not driven.
Abstract: An image deblurring system deblurs motion blurred images of a video stream captured from a moving object. An image deblurring method selects a blurred image from the video stream, selects blurred pixels from the blurred image, and calculates a movement offset for each of the blurred pixels according to coordinates of the blurred pixel in a frequency domain during the movement of the moving object. The method generates a point spread function according to the movement offset, and generates an image conversion formula according to the point spread function. The method converts each of the blurred pixels into a sharp pixel according to the image conversion formula, and generates a sharp image based on all of the sharp pixels.
