2048 results about "Color correction" patented technology

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.

System and method for controlling dynamically interactive parameters for image processing

A system and related techniques generate and present a set of linked, dynamically interactive image processing controls for image editing and optimization tasks. In embodiments a user interface may present a set of global editing modes such as color manipulation, exposure correction or others. Each mode may contain a hierarchical set of basic, intermediate and advanced controls such as one-button automatic fixes, color or saturation sliders or editable histograms or other curves. When a user wishes, for instance, to achieve a warmer color balance or perform other color-correction tasks, the system may automatically detect adjustments in one or more parameters, such as CMYK values, and automatically adjust the values of other parameters to enhance the intended correction or action. For instance when the magenta content on a CMYK slider is increased, the color saturation may be slightly increased or color temperature may be slightly raised, to create a warmer appearance in the color cast of the image. Other combinations of image parameters may be linked. According to embodiments, a set of editable curves such as histograms or gamma curves may be dragged or otherwise adjusted or manipulated by users, and saved for re-application to other images or at other times.

Image processing device, image processing method, program, storage medium and integrated circuit

It is an object to perform color correction that is simple and utilizes existing devices to achieve an increase in the feeling of depth in 2D images. Input image data are transformed into predetermined color information by a color information calculation portion 11. A correction amount control portion 10 determines a correction gain value for the color information according to depth information that has been input. A color information correction portion 12 performs color information correction based on the correction amount due to the contrast between the color information of a target pixel and representative color information of the surrounding region, and the correction gain value of the correction amount control portion. An output portion 13 converts this into a predetermined image format and outputs the result. Thus, by correcting the color information based on the contrast effect in conjunction with the depth information of the foreground and the background, for example, it is possible to easily increase the feeling of depth in a 2D image. Moreover, by controlling the color contrast effect with the depth information when performing the color correction, it becomes possible to more easily give a sense of depth that is perceived by humans.

Vehicle license plate recognition method based on video

The invention provides a vehicle license plate recognition method based on a video. According to the vehicle license plate recognition method based on the video, moving vehicles are detected and separated out with the vehicle video which is obtained through actual photographing by means of a camera serving as input, the accurate position of a vehicle license plate area is determined by conducting vertical edge extraction on a target vehicle image obtained after pre-processing, a vehicle license plate image is separated out, color correction, binaryzation and inclination correction are conducted on a vehicle license plate image, each character in the positioned vehicle license plate area is separated to serve as an independent character, feature extraction is conducted one each character, obtained feature vectors are classified through a classifier which is well trained in advance, a classification result serves as a preliminary recognition result, secondary recognition is conducted on the stained vehicle license plate characters according to a template matching algorithm imitating the visual characteristics of human eyes, and then a final vehicle license plate recognition result is obtained. The vehicle license plate recognition method based on the video has the advantages that hardware cost is reduced, the management efficiency of an intelligent transportation system is improved, the anti-jamming performance and the robustness are high, the recognition efficiency is high, and the recognition speed is high.

Image processing device, image processing method, image processing system, program, storage medium, and integrated circuit

The present invention executes color correction that improves the feeling of depth of a 2D image with ease and by using a preexisting device.
Input image data is first converted into brightness information by a brightness information calculation portion. The interest level within the image is then estimated by an interest level estimation portion based on that information. The vanishing point is then estimated by a vanishing point estimation portion. Next, a depth estimation portion estimates the degree of depth based on the distance from the vanishing point to a pixel i and the interest level of the pixel i, and calculates a depth correction gain value. A corrected image, obtained by controlling a depth correction image process based on the depth correction gain value, is converted to a predetermined image format and outputted by an output portion. Accordingly, by linking an interest level based on the brightness contrast/color contrast/blurriness amount with the depth estimation based on the vanishing point, the occurrence of abnormalities felt with images that do not properly match up with the perspective structure of the vanishing point, images that do not match the visual impression of humans, and so on can be reduced, making it possible to achieve a more natural and improved feeling of depth.
