Abstract: A system and an apparatus for improving image quality of an object in video telephony are described. The apparatus comprises an image detection unit, an image alignment unit and an image fusion unit. A near infrared light source in the image detection unit illuminates the object, such that the object is front illuminated. An image sensor alongside the near infrared light source generates a near infrared image and a visible image. An image alignment unit aligns the near infrared image and the visible image. An image fusion unit fuses the aligned near infrared image and aligned visible image pair to form a composite image of the object. The composite image of the object has improved image quality, image detail, and a reduction in shadows.

Abstract: The processing of a stereoscopic image using first and second images to facilitate computing a corresponding depth/disparity image can be facilitated by providing (101) the first and second images and then computing (103) a disparity value of each pixel in the second image by, at least in part, determining a likelihood of occlusion for at least some pixels comprising the second image using, at least in part, predicted occlusion information as corresponds to information contained in the first image. By one approach, this predicted occlusion information can be provided, at least in part, by processing (102) the first image, at least in part, by determining occlusion value information for at least some pixels as comprise the first image and then using the occlusion value information for the first image to determine a corresponding disparity information map for the first image.

Abstract: Disclosed is a method for setting the white balance of a video frame. The frame is first divided into sub-regions. Those sub-regions determined to be possibly dominantly monochromatic are eliminated from consideration, and the white balance is set by adjusting the color gain of the frame, the adjusting based on the other sub-regions in the frame. A sub-region is determined to be possibly dominantly monochromatic if the difference between its averaged color and each of a set of neutral reference colors is greater than a threshold. If the difference between the averaged color and at least one of the neutral reference colors is less than or equal to the threshold, then the sub-region is still determined to be possibly dominantly monochromatic if that neutral reference color, along with an illuminant type of a previous frame in the video, match closely enough to an element in an ambiguous reference color list.

Abstract: Described herein are systems and methods for expanding upon the single-distance-based background denotation to seamlessly replace unwanted image information in a captured image derived from an imaging application so as to account for a selected object's spatial orientation to maintain an image of the selected object in the captured image.

Abstract: A method and apparatus is provided for rendering an image. The method includes capturing a distorted input image using a color filter array to obtain an input image pattern having a single color channel per pixel. The input image is transformed to an input image signal. At least a portion of the input image signal is dewarped to obtain an undistorted image signal by (i) identifying selected coordinate points in the input signal that correspond to coordinate points in the undistorted image signal and (ii) determining a first color channel value for at least one of the selected coordinate points with a color correlation-adjusted interpolation technique using at least one nearest neighbor pixel having a color channel different from the first color channel.

Abstract: An electronic device (1100) and a method for character segmentation (100) includes an image analyzer (1110) that generates individual character images. The image analyzer binarizes (115) a gray scale image (200) of a horizontal row of characters by using a general threshold method to generate a first image (300). The image analyzer also binarizes (120) the gray scale image using an edge detection method to generate a second image (405). The image analyzer determines (125) a character row region (425) of the second image by using horizontal projection analysis. The image analyzer isolates (130) the character row region of the first image using the character row region of the second image. The image analyzer uses the character row region to generate (135) individual character images. The electronic device may include an image capture device (1105) and a character recognition program (1115).

Abstract: A method and structure for implementing color image acquisition and processing. Combined and direct interpolation and conversion from a first to a second color space of sensor color data provided to a device capable of receiving and displaying color image data, followed by color correction in the second color space, greatly simplifies acquisition and processing of color image data. Interpolation in the combined interpolation and conversion can optionally be vertex-based interpolation in which color data for virtual pixels for one or more pixels of interest can occur in parallel fashion. Conversion in the combined interpolation and conversion can be performed in accordance with a simplified conversion matrix that does not require the use of multiplier logic to be implemented but that does require compensation during subsequent color correction of the color data, also in the second color space.

Abstract: A photodetector (105) generates an electrical signal that has a value that changes approximately linearly at a rate that is proportional to an amount of light intensity incident on a photodetector since a most recent reset command was received at a reset input of the photodetector. A measurement circuit (110) generates a comparison state that is based on a comparison of the value of the photodetector signal to a reference signal in response to one of a plurality a sample pulses. A control circuit (160) generates the plurality of sample pulses at non-uniform time intervals and generates an elapsed time as an accumulation of the non-uniform time intervals occurring from the reset command to a change of the comparison state. In one embodiment, the reciprocal of an accumulated duration of the non-uniform time intervals is a linear function of a number of time intervals after the reset command.
