摘要： Embodiments of the disclosure relate to the field of image processing technologies, and disclose an image color adjustment method and apparatus and an unmanned aerial vehicle (UAV). The image color adjustment method is applicable to an image collection device. The method includes: determining a current photographing parameter of the image collection device during collection of a to-be-processed image, where the current photographing parameter includes a current exposure and a current color temperature; selecting, according to the current exposure and the current color temperature, an optimal color channel gain matching the current exposure and the current color temperature; and adjusting a color of the to-be-processed image according to the optimal color channel gain.

摘要： An image processing device a camera and a method for of encoding images captured by a camera are disclosed. For each image of an image sequence captured by the camera, the image is pre-processed by filtering the image by applying a privacy filter, the privacy filter being configured to distort the image in such a way that privacy is achieved in the filtered image, and, for at least a subset of the filtered images, by colour revising the filtered image by changing colour of pixels of a plurality of scattered areas of the filtered image such that a respective colour of one or more pixels of each area of the plurality of scattered areas represents one or more original colours of one or more pixels before filtering at a location of that area in the filtered image. The pre-processed images are then encoded into an encoded video stream.

摘要： One embodiment provides a method comprising receiving an input content, and receiving ambient contextual data indicative of one or more ambient lighting conditions of an environment including a display device. The input content has corresponding metadata that at least partially represents a creative intent indicative of how the input content is intended to be viewed. The method further comprises adaptively correcting the input content based on the ambient contextual data to preserve the creative intent, and providing the corrected input content to the display device for presentation. The adaptively correcting comprises applying automatic white balancing to the input content to correct color tone of the input content.

摘要： A system and method for generating an improved color filter for modifying the spectral response of a vision system are disclosed. the method includes receiving an RGB spectral response of the vision system for a color target under predetermined illumination, generating a model, using the RGB spectral response, of the vision system when subject to a filter, the model including a bounded total transmittance of light by the filter that is set by a predetermined parameter and executing, by a processor of a computer system, computer program instructions configured to apply the model to a bilinear optimisation problem that simultaneously determines:
i) a color correction matrix to transform the RGB spectral response to XYZ color space; and,
ii) parameters of the color filter.
The method further executes computer program instructions configured to solve the bilinear optimisation problem and, then provides a color filter using the parameters.-

摘要： A projection device, including an illumination system, a control element, a driving element, a light valve, and a projection lens, is provided. The illumination system includes multiple light sources for providing multiple light beams to be combined into an illumination light beam. The driving element respectively drives the light sources in a first mode or a second mode, so that the light beams have respective luminous brightness, and the driving element is switched from the first mode to the second mode according to a first signal. The control element provides the first signal to the driving element according to an optical state or a time state of the projection device. The light valve is adapted to convert the illumination light beam into an image light beam. The projection lens is adapted to project the image light beam out of the projection device.

摘要： A transmission device including circuitry is provided. The circuitry is configured to apply photoelectric conversion characteristics to high dynamic range video data to obtain transmission video data. The circuitry is configured to transmit a container including a video stream obtained by encoding the transmission video data. The circuitry is configured to insert type information to designate the type of conversion characteristics corresponding to the applied photoelectric conversion characteristics for photoelectric conversion of the transmission video data into a layer of the video stream and/or a layer of the container. The type of the conversion characteristics designated by the type information is determined regardless of luminance of a display.

摘要： A method for changing an image file based on a toning coefficient includes receiving an image file including an image having a plurality of pixels. Toning characteristic function is determined for each pixel of the received image. Distribution of the plurality of pixels of the received image is analyzed using the toning characteristic function. The toning coefficient of the received image is determined based on the analyzed distribution of the plurality of pixels. A degree of toning of the received image file is changed using a user specified criteria based on the determined toning coefficient.
