An image processing apparatus includes an acceptance unit and a color conversion property creation unit. The acceptance unit accepts sets of image information each of which is composed of image information of an image before color conversion and image information of an image after color conversion. The color conversion property creation unit creates a color conversion property for color conversion of an image on the basis of pieces of image-capture setting information that are set for image-capture conditions used when the images before color conversion are captured.

An image processing apparatus includes an image acquire unit that acquires an image in which at least one element in a first color space has linear characteristics; and a processor. The processor is configured to adjust a white balance of the image which is acquired by the image acquire unit; control the adjustment content of the white balance, on the basis of a specific color serving as a reference; convert each of a plurality of portions in the image in which the white balance has been controlled by the adjustment content of the white balance, into one element in a second color space; and apply predetermined image processing to the acquired image in which the white balance has not been adjusted, by using the converted information.

A method for facial skin age estimating and electronic device. The method includes: adjusting illumination component and color component of a facial image depending on a reference image; analyzing a plurality of evaluation index for assessing skin condition on interest area of the facial image and estimating the skin age of the facial image, according to the evaluation index.

Disclosed are systems, methods, and computer-readable storage media to enhance an image on a mobile computing device. In some aspects, a user interface on the mobile computing device provides a plurality of image filters, each of the image filters associated with a different replacement sky type. Upon application of one of the plurality of image filters to an image, the mobile computing device is configured to identify a sky portion of the image, modify a color mapping of a non-sky portion of the image, and replace the sky portion of the image with replacement sky data corresponding to the applied image filter.

The present document provides image processing methods and apparatus. One claim recites: obtaining a signal to be encoded in color image data, the signal comprising a plural-bit payload; predicting a resulting color of overprinting several inks on a substrate, the overprinting representing the color image data encoded with the signal; using the resulting color for both i) visibility evaluation of the overprinting, and ii) signal robustness evaluation of the overprinting as seen by an imaging device. Other claims and combinations are provided.

A detection method includes image acquisition processing for acquiring an image; white balance adjustment processing for adjusting a white balance of the image which is acquired in the image acquisition processing; control processing for controlling adjustment content of the white balance in the white balance adjustment processing, on the basis of a specific color serving as a reference; and detection processing for detecting a portion satisfying a predetermined condition relevant to the specific color from the acquired image in which the white balance has not adjusted, on the basis of the image in which the white balance has been adjusted by the adjustment content of the white balance controlled in the control processing.

The present application includes methods, systems and computer readable storage devices for determining a color score for at least a portion of a biological tissue. The subject matter of the application is embodied in a method that includes obtaining a digital image of the biological tissue, and receiving a selection of a portion of the image as an evaluation area. The method also includes determining for each of a plurality of pixels within the evaluation area, a plurality of color components that are based on a Cartesian color space, and determining, from the color components, a hue value in a polar coordinate based color space. The method further includes determining a color value based on the hue value for each of the plurality of pixels, and assigning a color score to the evaluation area based on an average of the color values of the plurality of pixels.

Disclosed herein are system, method, and computer program product embodiments providing interface color branding. An embodiment operates by receiving a primary color associated with a theme of a user interface. A first color code corresponding to the primary color is determined. The first color code is converted into a second color code corresponding to the primary color, wherein the first color code is in a device-dependent color format and the second color code is in a device-independent color format. A secondary color corresponding to each of one or more portions of the user interface is derived from the second color code. Each secondary color is converted from the device-independent color format into the device-dependent color format. The one or more portions of the user interface are colored in the device-dependent color format.

The present disclosure relates generally to encoding signals for spot colors. In one implementation a substitute spot color+CMY tint is selected to replace an original spot color. The CMY tint can be transformed to carry an encoded signal. Of course, other features, combinations and technology are described herein.
