Abstract: A method for transforming an image expressed in terms of a first image encoding to a second image encoding, includes converting a set of original scene exposure-factor values into corresponding first and second image encoding values. A transform is then derived between the first image encoding values and the second image encoding values. The transform is then applied to an image encoded in said first image encoding. Examples of different encoding that can be transformed include Rec. 709, sRGB and other known image encoding standards. A system for performing such transformations as well as an electronic device that is capable of performing such transformations are also disclosed.

Abstract: A printing system includes a linehead that jets ink onto a moving print media to print a test block and an integrated imaging system positioned downstream of the linehead with respect to a media transport direction. The integrated imaging system includes an opening in a housing for receiving light reflected from a moving print media. A folded optical assembly in the housing receives the reflected light and transmits the light a distance. One or more image sensors, having known color filter arrays, within the housing each receive the light and capture one or more images of the printed test block. An image processing device is connected to the integrated imaging system for receiving pixel data from the one or more image sensors and configured to determine a color of the ink and a density of the printed test block using the pixel data.

Abstract: A method for color density correction in a printing system that includes a linehead, with one or more printheads, that jets ink onto a moving print media and an integrated imaging system that captures images of content printed on the moving print media is provided. One or more pixel data values and a measured density value trace for a printed test block are produced by scanning the test block and averaging pixel data in a print media transport direction. A color and a density of the ink in the printed test block are determined using the pixel data values. The measured density value trace is compared with a respective reference density value. It is determined whether there is a difference between the measured density value trace and a reference density value is determined. If there is a difference, ink laydown for the printhead is adjusted based on the difference.

Abstract: A method for generating a target display characteristic for a non-CRT display device includes establishing a sequence of luminance-factor values corresponding to original-scene neutrals. The luminance-factor values are converted to corresponding Rec. 709 signal values. The luminance-factor values are then mapped according to a desired system tone reproduction characteristic to corresponding luminous intensity values to be reproduced by the non-CRT television display device. The target display characteristic is generated by relating the corresponding Rec. 709 signal values to corresponding luminous intensity values.

The electronic display panel includes a display and a bordering housing surrounding the display and having an opening, that in combination with the opening in the conventional picture frame, allow the display to be visible through the openings. The height, width, and thickness of the bordering housing are configured to allow the electronic display panel to be engaged with multiple commercially-available conventional picture frames.

Abstract: A video signal includes a plurality of frames of image data. A single frame of image data or multiple frames of image data, one or more reduced resolution frames, or a portion or portions of one or more frames or reduced resolution frames can be analyzed to determine initial statistics. One or more correction operations are then performed on the initial statistics to generate initial correction values. The one or more correction operations include a balance correction operation, a flare correction operation, and a tonal correction operation. After the initial correction values are determined, a temporal filter is applied to the initial correction values to generate final correction values. Optimized image data is then generated by applying the final correction values to image data in one or more frames.
