Abstract: Provided is a method for marking a focused pixel. The method includes: in response to marking a focused pixel of a first image based on a focus threshold, adjusting the focus threshold in the case that an adjustment condition is satisfied; marking a focused pixel of a second image based on the adjusted focus threshold. The adjustment condition includes: a focus degree of the first image is less than a target focus degree, and/or, the focus degree of the first image is greater than the target focus degree. Moreover, a similarity between the first image and the second image is greater than a similarity threshold, and a difference between a focus degree of the second image and the target focus degree is less than a difference between the focus degree of the first image and the target focus degree.

Abstract: A video frame interpolation method and device, and a computer-readable storage medium are described. The method includes: inputting at least two image frames into a video frame interpolation model to obtain at least one frame-interpolation image frame, training the initial model using a first loss to obtain a reference model, copying the reference model to obtain three reference models with shared parameters, selecting different target sample images according to a preset rules to train the first/second reference model to obtain a first/second frame-interpolation result; selecting third target sample images from the first/second frame-interpolation result to train the third reference model to obtain the frame-interpolation result, obtaining a total loss of the first training model based on the frame-interpolation result and the sample images, adjusting parameters of the first training model based on the total loss, and using a parameter model via a predetermined number of iterations as the video frame interpolation model.

Abstract: There is provided a data processor for a display device including a display panel having a first resolution. The data processor includes a first mode selector and a player. The first mode selector includes a distance detector, a comparator, and a transmission resolution adjustor. The distance detector may detect a current distance between a viewer and a display surface of the display panel. The comparator determines an amount of change of the current distance from a previous distance. The transmission resolution adjustor determines a second resolution according to a threshold range within which the previous distance falls and the amount of change. The player processes received external image data as intermediate data having the second resolution.

Abstract: A display control device is disclosed herein, which includes a plurality of data generating chips and a plurality of data processing chips, corresponding to one another in a one-to-one relationship. The plurality of data generating chips are configured to receive an image signal. The image signal includes a plurality of image region signals, each corresponding to a different region of an image frame. Each data generating chip is configured to receive, and to conduct data processing to, at least one image region signal to generate image region data, and to send the image region data to a corresponding data processing chip. Each data processing chip is configured to conduct image processing to the image region data from a corresponding data generating chip to generate an image output signal, and to output the image output signal. On this basis, a display method and a display apparatus are also disclosed.
