Abstract

The present application discloses a method and device for dynamic grayscale reconstruction between display frames based on LED lamps. The method includes: receiving a grayscale signal value; converting the grayscale signal value from a linear brightness dimming algorithm to a nonlinear brightness dimming algorithm , generate a reconstructed gray-scale signal value; adjust the brightness change of the LED according to the reconstructed gray-scale signal value. The present application solves the technical problem of solving the sudden change of the gray level.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a method and a device for dynamic grayscale reconstruction between display frames based on LED lamps. Background technique [0002] LED lamps are more and more widely used in the field of lighting and landscape lighting. People's pursuit of LED lighting display effect is getting higher and higher. People's visual senses have changed from only looking at brightness and color changes to paying attention to healthy lighting and feeling light color changes. It needs to be smooth, delicate transition, no stroboscopic and no jitter phenomenon in gray level change, which is in line with the best visual effect. At present, most of the communication protocols of domestic and foreign LED lamps use the DMX512 protocol for data transmission. The level is 256 levels. [0003] In the process of implementing this application, the inventors found that there are at least the following problems in the prior...
