摘要： In one example, a method for white balancing image data includes obtaining, for a zone of a color space, a mesh defining a plurality of polygons having vertices that are each associated with one or more white balance parameters; identifying a polygon of the plurality of polygons that includes a pixel of the image data; determining one or more white balance parameters for the pixel of the image data based on an interpolation of white balance parameters associated with vertices of the polygon that includes the pixel of the image data; and performing, based on the one or more white balance parameters for the pixel of the image data, a white balance operation on the pixel of the image data.

摘要： A tint of an object according to a second image capturing device is corrected by a first parameter for correcting a tint of a second object that the second image capturing device captured in a first time zone to a tint of a first object that a first image capturing device captured in a first time zone. If a third object captured by a third image capturing device corresponds to the first object, a parameter for correcting a tint of the third object to the tint of the first object is used for correcting a tint of an object according to a third image capturing device. If the third object corresponds to the second object, the first parameter and a third parameter for correcting the tint of the third object to the tint of the second object is used for the foregoing tint correction.

摘要： A camera tuning circuit has a first storage space, a second storage space and a controller. The first storage space stores a first reference camera correction setting for a reference camera module under a first color temperature. The second storage space stores a second reference camera correction setting for the reference camera module under a second color temperature, wherein the second color temperature is different from the first color temperature. The controller receives a default camera correction setting of a target camera module, the first reference camera correction setting, and the second reference camera correction setting, and generates a tuned camera correction setting for the target camera module according to the default camera correction setting, the first reference camera correction setting, and the second reference camera correction setting.

摘要： The disclosure concerns processing hyperspectral or multispectral images. Image data comprises a sampled image spectrum represented by first values for each pixel location representative of an intensity associated with a wavelength index. A processor determines for each pixel location second values based on a measure of similarity between pixel locations with respect to the first values such that two pixel locations that 5 are similar with respect to the first values are also similar with respect to the second values. The processor then stores for each pixel location the determined one or more second values associated with that pixel location on a data store. This way, the image data is made suitable for applications, such as clustering or displaying, while pixels that are similar in the input image are also similar in the output data. This means that a 10 structure between the pixels in the input image is preserved.

摘要： A computing device may obtain an input image. The input image may have a white point represented by chrominance values that define white color in the input image. Possibly based on colors of the input image, the computing device may generate a two-dimensional chrominance histogram of the input image. The computing device may convolve the two-dimensional chrominance histogram with a filter to create a two-dimensional heat map. Entries in the two-dimensional heat map may represent respective estimates of how close respective tints corresponding to the respective entries are to the white point of the input image. The computing device may select an entry in the two-dimensional heat map that represents a particular value that is within a threshold of a maximum value in the heat map, and based on the selected entry, tint the input image to form an output image.

摘要： The present disclosure relates to a method and a device for setting a shooting parameter. The method includes displaying a digital color temperature adjusting key and at least one scenario color temperature adjusting key in a menu bar on the touch screen, receiving a tapping signal on a digital color temperature adjusting key displayed on a touch screen, displaying a scrolling list according to the tapping signal. A first set of n color temperature values are displayed in the scrolling list and one color temperature value in the n color temperature values is in an active state. The method further includes receiving a scrolling signal associated with the scrolling list, scrolling the first set of n color temperature values to display a second set of n color temperature values in the scrolling list in response to the scrolling signal, and selecting as the shooting parameter a color temperature value which is in an active state. The present disclosure may solve the problem that the number of scenario adjusting modes is limited and a user is not able to adjust the color temperature values of all the scenarios.
