The invention discloses a method and system for adjusting white balance, and a display, and belongs to the technical field of display. The method for adjusting the white balance is applied to the display, and comprises the following steps: identifying image information of a currently played frame image to be adjusted; obtaining a matched target color temperature value according to the image information; and adjusting a white balance parameter of the frame image to be adjusted according to the target color temperature value. According to the method disclosed by the invention, by identifying the image information of the currently played frame image to be adjusted, and obtaining the matched target color temperature value according to the image information, the white balance parameter of the frame image to be adjusted is automatically adjusted according to the target color temperature value, the purpose of correspondingly adjusting the white balance parameter of the currently played frame image contents in real time can be achieved, so that the sense of tableau of the image is more realistic, and the visual effect is enhanced.

Methods and apparatus, including computer program products, for detecting malfunction in a thermal camera. A first average response value is determined for a first shutter image captured by an image sensor in the thermal camera. A second average response value is determined of a second shutter image captured by the image sensor in the thermal camera. The first average response value and the second average response value are compared. In response to determining that the first average response value and the second average response value differ by more than a predetermined value, an indication of a malfunction of the thermal camera is provided.

A computer-implemented method for color correcting images captured using a mobile computing device is described. A wavelength of light is emitted from a display of a mobile computing device. An image of the emitted wavelength of light is captured using a camera on the mobile computing device. The image of the wavelength of light emitted from the display of the mobile computing device that is captured using the camera on the mobile computing device is analyzed. At least one image captured using the camera on the mobile computing device is modified based on the analysis of the image of the wavelength of light emitted from the display of the mobile computing device.

METHOD AND SYSTEM FOR DETERMINING PARAMETERS OF AN IMAGE PROCESSING PIPELINE OF A DIGITAL CAMERA
20170272619 · 2017-09-21 ·

A method and system for determining parameters of an image processing pipeline of a digital camera is disclosed. The image processing pipeline transforms captured image data on a scene into rendered image data. Rendered image data produced by the image processing pipeline of the camera is obtained from the captured image data on the scene. At least a subset of the captured image data on the scene is determined and a ranking order for pixels of the rendered image data is obtained. A set of constraints from the captured image data and the ranked rendered image data is determined, each constraint of the set being determined in dependence on selected pair combinations of pixel values when taken in said ranking order of the rendered image data and corresponding pair combinations of the captured image data. Parameters of the image processing pipeline are determined that satisfy the sets of constraints.

Updating calibration of a three-dimensional measurement system

A method of calibrating a three-dimensional measurement system having a plurality of cameras and at least one projector is provided. The method includes performing a full calibration for each camera/projector pair where the full calibration generates at least two sets of correction matrices. Subsequently, an updated calibration is performed for each camera/projector pair. The updated calibration changes less than all of the sets of correction matrices.
