Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Typically the light color is measured on a scale known as color temperature, as well as along a green–magenta axis orthogonal to the color temperature axis.

The invention discloses a color blindness image recoloring method based on joint saliency, and the method comprises the following steps: retrieving a large number of images with content similarity according to an image retrieval technology; performing color blindness simulation on the retrieved image; performing saliency detection on the color blindness simulation image and the original image by using joint saliency detection; analyzing a detection result, and selecting an optimal reference image; and re-coloring the grey-scale map by using an image coloring technology based on a reference image. According to the invention, color blindness image recoloring based on joint saliency is realized, the purpose of saliency correction is achieved, and the requirement of required color correction is met.

Image sensing apparatus and color-correction matrix correcting method and look-up table establishing method

ActiveUS20150271459A1Easy accessImage enhancementImage analysisImage sensorColor correction

An image sensing apparatus, a color-correction matrix correcting method and a look-up table establishing method are provided. The image sensing apparatus calculates a block statistics value corresponding to a block of pixels in an image sensor array. Based on a look-up table, the image sensing apparatus determines a covariance value corresponding to a current gain value. According to the covariance value and the block statistics value, the image sensing apparatus corrects a color-correction matrix corresponding to the block of pixels. The image sensing apparatus can use an amended color-correction matrix to correct the color of the pixel, so as to reduce chroma noise or other noise.
