Display characteristics are calculated using a first captured image for determining ambient light characteristics and a second captured image including the ambient light characteristics and the display characteristics by removing the ambient light characteristics from the second captured image, and display correction is performed based on the display characteristics. This can provide a device that saves time and effort such as moving a color-measurement device when correcting the display characteristics of one or more display devices and that is able to perform display configuration even if a large portion is illuminated by ambient illumination.

Display correction apparatus, program, and display correction system

A system for influencing a state of a user includes a display with a light source for emitting light influencing the state of the user. A light controller selectively controls the emission of the light including at least one of; (1) the spectrum of the light; (2) the duration of the light; 3) the distribution of the light; (4) the intensity of the light; and (5) the timing of the light. An analysis engine capable of providing a signal to the light controller indicating a desired emission of the light based upon selectively illuminating one or more of a plurality of different blue light sources, each of which having a different peak spectrum.

Methods and systems for identifying digital image characteristics

Systems and methods for generating color corrected digital image data from a document image according to personal preferences of an identified user of the digital image copy. A color correction profile is provided defining color correction parameters for a particular identified user. The digital image copy is generated in accordance with the color correction profile by replacing problematic colors with alternate presentations as defined by the color correction parameters. The alternate presentations may include corrections to compensate for colorblindness of an identified user. The document image may be logically segmented to identify objects associated with each of a plurality of segments of the document image such as text, graphics, photographic images, etc. The color correction profile may define different color correction parameters to be associated with each defined type of segment.

Aspects of the present invention relate to systems and methods for characterization of background regions of substantially-uniform color in a digital image. According to a first aspect of the present invention, a histogram of the first-channel values of a plurality of image pixels may be formed, and a peak region in the first-channel histogram may be detected. Subsequently a histogram of image values of a second channel may be formed accumulating second-channel values for only those image pixels with first-channel values within the peak region of the first-channel histogram, and a peak region in the second-channel histogram may be detected. An image characteristic may be associated with image pixels with first-channel and second-channel values within the first-channel peak and the second-channel peak regions, respectively.

Aspects of the present invention are related to methods and systems for determining a background color in a digital image. A background color value for a pixel in an image may be determined by summarizing the color values in a color buffer, wherein the color values in the buffer may have been selectively added to the color buffer, from the image data, based on one, or more, criteria which may be related to edge density, image uniformity, non-local color information, a foreground color estimate and other selection criterion. The background color for the pixel maybe determined in a forward scan and updated during a backward scan.

Methods and systems for background color extrapolation

Aspects of the present invention relate to systems and methods for refining text segmentation results. Non-text, line elements in a text map may be detected and removed from the text map. Pixels associated with vertical and/or horizontal lines may be identified in the text map based on a background-color constraint, a directional color constraint and a continuity constraint. Run counters and run-reset counters associated with a direction may be used to identify pixels meeting the continuity constraint.

A method for attenuation of near-neutral image colors is described. The pixel chroma is determined. A chroma control point is determined. A pixel color is shifted toward neutral. An imaging device that is configured for attenuation of near-neutral image colors is described. The imaging device includes a processor. The imaging processing device includes memory in electronic communication with the processor. Instructions are stored in the memory. The instructions are executable to determine pixel chroma. The instructions are also executable to determine a chroma control point. The instructions are further executable to shift a pixel color toward neutral.

An integrated infrared (IR) and full color complementary metal oxide semiconductor (CMOS) imager array is provided. The array is built upon a lightly doped p doped silicon (Si) substrate. Each pixel cell includes at least one visible light detection pixel and an IR pixel. Each visible light pixel includes a moderately p doped bowl with a bottom p doped layer and p doped sidewalls. An n doped layer is enclosed by the p doped bowl, and a moderately p doped surface region overlies the n doped layer. A transfer transistor has a gate electrode overlying the p doped sidewalls, a source formed from the n doped layer, and an n+ doped drain connected to a floating diffusion region. The IR pixel is the same, except that there is no bottom p doped layer. An optical wavelength filter overlies the visible light and IR pixels.
