The application discloses an intelligent color-changing light source system, and relates to the technical field of LED intelligent lighting; a power management module receives a mode switching instruction issued by a micro control module, and switches the operation condition according to the load demand corresponding to color output; a driving module receives a PWM pulse signal issued by the micro control module, and adjusts the driving current of an RGBW four-channel LED array module; a color perception module is used for collecting ambient light intensity, color temperature and color distribution data in real time, and transmitting the data to the micro control module for color adaptation and calibration; a closed-loop feedback adjustment module obtains color deviation through difference calculation based on the data collected by the color perception module, in combination with preset color parameters, and transmits the color deviation to the micro control module; the micro control module generates a calibration signal and sends the calibration signal to the driving module, so as to correct the driving current of each channel of the RGBW four-channel LED array module. The application can meet the requirements of low power consumption, fast response and high color precision.

The present disclosure relates to the technical field of display, and particularly relates to a display method, a display device and a computer readable storage medium. The method comprises: acquiring a current frame image; performing N times of preprocessing operations based on the current frame image to determine N preprocessing images; wherein the preprocessing operation at least comprises any one of a downsampling operation and a filtering operation, an nth preprocessing image is obtained based on a target image, the target image comprises any one of the current frame image and an (n-1)th preprocessing image, when n equals to 1, the target image is the current frame image, when n is greater than or equal to 2, the target image is the (n-1)th preprocessing image, n and N are positive integers, and 1<=n<=N; determining an updated frame image based on at least one preprocessing image; and controlling a display to display the updated frame image.
