Abstract

The invention discloses an inter-frame dynamic gray scale reconstruction method and device based on LED lamp display. The method comprises the following steps: receiving a gray scale signal value; converting the gray scale signal value from a linear brightness dimming algorithm to a nonlinear brightness dimming algorithm to generate a reconstructed gray scale signal value; and adjusting the brightness change of LED according to the reconstructed gray scale signal value. According to the invention, the technical problem of gradient sudden change of gray level change is solved.

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...
