Abstract: A method for obtaining a light source spectrum includes: obtaining first information in a current photographing scene, where the first information includes at least one of a first image generated by a red, green, and blue (RGB) sensor or a light intensity of light received by each pixel on a first multispectral sensor; inputting the first information into a first model to obtain a probability that a light source in the current photographing scene belongs to each type of light source; and determining a spectrum of the light source in the current photographing scene based on the probability that the light source in the current photographing scene belongs to each type of light source and a spectrum of each type of light source.

Abstract: A method is provided for recording a video. The method includes generating a first set of video frames corresponding to a first time duration, generating a second set of video frames corresponding to a second time duration, inserting a third set of video frames to the second set of video frames, and automatically generating a combined video based on the first, second, and third sets of video frames. At least a part of the combined video is associated with a playback time duration greater than the second time duration.

Abstract: A method includes detecting an input operation performed on a display screen of a terminal when the display screen is touched and when a color temperature adjustment region is displayed on the display screen, converting, in response to the input operation, coordinates of an operation point corresponding to the input operation into a first color parameter, obtaining ambient light converting a color parameter of the ambient light into a second color parameter, integrating the first color parameter and the second color parameter to obtain a third color parameter, converting the third color parameter into a target color parameter, and displaying the target color parameter on the display screen of the terminal.

Abstract: An image display optimization method and apparatus, and a terminal are provided to resolve a prior-art problem that it takes a long time to display an image when scenario information analysis is added. The method includes: identifying scenario information included in a to-be-displayed image when receiving a display instruction that is triggered by a user and that is used to display the to-be-displayed image, where the scenario information is written into the to-be-displayed image when the camera shoots the to-be-displayed image; performing display optimization on the to-be-displayed image according to the identified scenario information; and displaying the display-optimized to-be-displayed image.

Abstract: A display driving device includes an encoding unit and a frame memory. The encoding unit is configured to generate final mode information and a compressed bit stream based on a macro block and a first reference pixel, and generate a final bit stream using the final mode information and the compressed bit stream. The frame memory is configured to store and provide the stored final bit stream to a decoding unit. The final mode information includes mode information and a reconstruction reference value. The mode information indicates a selected mode from a plurality of modes, each of the plurality of modes indicating selection pixels and non-selection pixels in the macro block. The selection pixels are pixels in the macro block selected for undergoing a compression operation, the non-selection pixels are pixels not selected for undergoing the compression operation, and the reconstruction reference value indicates encoding information for the non-selection pixels.

Abstract: A display controller includes a local contrast enhancement circuit that includes a plurality of scale circuits. Each scale circuit includes a block separation circuit configured to divide input display data into sub blocks, a calculation circuit configured to calculate a feature value that characterizes each of the sub blocks, and a storage device configured to store the feature value. The number and size of the sub blocks differ among the scale circuits.
