Device information is extracted from a graphical object's data file to dynamically generate a profile suitable for processing by a color management system. In one embodiment, the graphical object is an image and the graphical object's data file is generated by a digital camera.

Managing dynamic device color profiles

A method comprising determining an optimal color correction matrix accounting for both total noise variance and color reproduction error for a captured image; and correcting the colors of said captured image using said optimal color correction matrix.

Methodology for color correction with noise regulation

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.

Image processing methods and apparatus

A system of indexing discrete wavelet transform data, after entropy encoding, allows access to particular frames and sub-bands without decomposing all of the data to find the information of interest. In one embodiment a header may include the frame size in bytes followed by the sizes of each of the sub-bands in a predetermined order.

Indexing wavelet compressed video for efficient data handling

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.

Method and apparatus for adaptively sharpening local image content of an image

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 captured image based, at least in part, on a measure of the edges and brightness of the captured image. A kernel is applied to the captured image using the adaptively computed crispening parameter.

Method and apparatus for adaptively sharpening an image

A method including intra-frame coding a first sequence of video data using Discrete Wavelet Transform; and inter-frame coding a second sequence of video data using Discrete Wavelet Transforms, the second sequence of data interspersed with the first sequence.

Hardware efficient wavelet-based video compression scheme

What is disclosed is a method comprising performing an observation on a sensor having a plurality of pixels, for each of the pixels that are unclassified, determining a score according to the observation, if the score for the each pixel satisfies a stopping condition, classifying the each pixel as being one of either defective or functional, and repeating the steps of performing, determining and classifying for any the pixels remaining unclassified after determining the score.

Robust sequential approach in detecting defective pixels within an image sensor

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.

Using an electronic camera to build a file containing text

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.

Hi-speed deterministic approach in detecting defective pixels within an image sensor

In one embodiment, a method for determining a focus value in an image, including selecting an area of interest in the image and a color plane of interest, is described. The color plane of interest within the area of interest is filtered to produce a filtered region. The mean absolute value of the filtered region is determined.
