    摘要: A method includes capturing an optical image to form raw data indicative of the optical image and using a look-up table to transform the raw data into transformed data that indicates a second image. A white color balance of the second image is computed, and the values in the look-up table are modified based on the computed white color balance.

    摘要: An embodiment of the invention is directed to a method of building an electronic file, using an electronic camera such as a digital camera, that captures 3-dimensional objects. A number of image data tiles that represent the images are generated by the camera. A number of text data tiles each containing text recognized in a corresponding one of the image data tiles is generated. The method includes searching for overlapping text in the text tiles, and pasting the text tiles in proper alignment into an electronic file.

    摘要: Briefly, in accordance with one embodiment of the invention, a method of sharpening an image includes the following. A crispening parameter is adaptively computed for a local region of a captured image based, at least in part, on a measure of the local contrast and the local brightness. A kernel is applied to the local region of the captured image using the adaptively computed crispening parameter.

    摘要: What is disclosed is a method including downloading a sequence of images from an image sensor, and then marking on a map a pixel location of the sensor defective if a Defective Vote score exceeds a first threshold, the score tallied over all captured images. The defective pixel map is stored on a host computer, which performs the defective pixel detection on behalf of the sensor, rather than directly on the device incorporating the image sensor.
