摘要： A first and a second image (401 and 501) containing a shared region of interest (400) are captured (201 and 202) using a rolling shutter mode of image capture. These two images are captured at different times, such that the second image follows the first image by a given amount of time. A corrected image is then formed (203) of the region of interest by modifying at least one of the first and second images as a function, at least in part, of the given amount of time that separates capture of the two images along with pixel capture delay times as correspond to the rolling shutter mode of image capture (the latter referring, by approach, to pixel row capture delay times as characterize the rolling shutter image capture process itself)

摘要： A method and apparatus for object-of-interest image capture accomplishes the functions of capturing (120) a current image, determining (125) an object region of the object-of-interest in the current image, calculating (130) a contrast measurement of the object region, and identifying (135) the current image as having an optimized object region when an iteration measure meets a criterion. The current image is captured using a local exposure value determined from luminance readings of pixels within an object region of an object-of-interest of a previous image.

摘要： 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).

摘要： 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.

摘要： 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.
