Embodiment 1

[0141] by Figure 4 As shown, the generation rate V1 of the target pulse sequence is the same as the display rate V2 of the target display array, and the generation resolution R1 of the two is the same as the display resolution R2, and the light-emitting state signal includes on and off:

[0142] Based on the ratio of the generation rate V1 to the display rate V2 being 1, and the ratio of the generation resolution R1 to the display resolution R2 being 1, the temporal-spatial relationship is determined as:

[0143] The target display array corresponds to a pulse plane corresponding to the input target pulse sequence, and each display unit corresponds to a pulse signal of a pulse position on the pulse plane. The display unit is, for example, a pixel unit.

[0144] The threshold value is 1, the pulse signal is 1, the cumulative pulse signal value is 1, the display status information is on, and the corresponding display unit is controlled to light up; the pulse signal is 0, the c...

Embodiment 2

[0146] by Figure 5 As shown, the generation rate V1 of the target pulse sequence is the same as the display rate V2 of the target display array, both are 6*6 (that is, W=H=6), and the generation rate V1 of the target pulse sequence=40000 frames / second, the target display Array display rate V2 = 8000 frames per second:

[0147] For the pulse signal during 5 / 40000 seconds, according to the input order, it is expressed as follows (the first input pulse signal is first, and the second input pulse signal is last): the above target pulse sequence is according to the resolution 6*6 and the input order, the above target pulse The sequence corresponds to 5 pulse planes (pulse frames), for example Figure 6 As shown, based on the same resolution, each display unit corresponds to a pulse position in the pulse plane in space; based on V1 / V2=5, then in time, each display unit corresponds to the pulse in 5 pulse planes Position pulse signal. The five pulse signals are accumulated, and d...

Embodiment 3

[0150] by Figure 7 As shown, the generation resolution R1 of the input target pulse sequence is 6*6, and the display resolution R2 of the target display array is 2*2; the generation rate of the target pulse sequence V1=40000 frames / second, and the display rate of the target display array is V2=8000 frames / second; display status information including voltage value:

[0151]The received target pulse sequence is the same as that in Embodiment 2. And based on resolution R1 / R2=9, each display unit corresponds to 9 pulse positions in the pulse plane; based on V1 / V2=5, each display unit corresponds to pulse signals in 5 pulse planes. At this time, the 9 pulse positions of the 5 pulse planes are accumulated, and the weighted accumulation method is adopted. The pulse signals of different pulse positions have different weights, and the weight matrix is:

[0152] 1 2 1 2 4 2 1 2 1

[0153] .

[0154] For the display units at positions (1, 1) and (1, 2), th...

Abstract

The invention discloses a display method and device based on pulse signals, electronic equipment and a medium. By applying the technical scheme of the invention, the display state of each display unit on the display panel can be determined by calculating the space-time relationship between the target pulse sequence and the target display array, so that the optical signal information recorded by the target pulse sequence signal can be completely displayed; and an optical signal change process of an original scene can be accurately reproduced. The process does not involve the traditional image reconstruction, so that the defect that the information amount carried by the original pulse signal is lost in the prior art is also avoided.

Description

technical field [0001] This application relates to data processing technology, especially a display method, device, electronic equipment and medium based on pulse signals. Background technique [0002] Video technology is widely used. Furthermore, due to its own design concept, traditional video technology is increasingly unable to meet the current visual task requirements. Specifically, the traditional video technology is to sample the scene completely according to the preset fixed frequency, which cannot reflect the dynamic changes of the scene, and it is easy to oversample or undersample the current scene, resulting in large video data redundancy and low temporal resolution. Problems such as low and high-speed motion are easy to blur. [0003] In addition, most of the existing display devices use 8-bit or 16-bit RGB display mode to display the image sequence signal captured in the traditional way, which does not match the new visual information expression method of the t...
