Embodiment 1

[0076] Such as figure 1 shown by the display unit D 1 , display unit D 2 Composed of a set of display units to display dynamic image codes, D 1 for LED 1, D 2 For LED 2, each LED can be switched between two display states of "on" and "off", where white indicates that the LED is "on", and black indicates that the LED is "off". 1 Indicates that the display state is "bright", use S 2 Indicates that the display status is "off".

[0077] From display state S 1 switch to S 2 , or from display state S 2 switch to S 1 For 1-step switching, from display state S 1 switch to S 1 , or from display state S 2 switch to S 2 Switch to 0 steps.

[0078] For the set of display units, there are four display modes, such as Figures 1 to 4 shown, respectively with S 1 S 1 , S 2 S 1 , S 1 S 2 , S 2 S 2 To represent.

[0079] In each period, the display mode of the set of display units is switched once, and according to the display mode before and after the switch, more specif...

Embodiment 2

[0120] Such as Figure 5 or 6, through the display unit D 1 , display unit D 2 , display unit D 3 A set of display units is formed to display dynamic image codes.

[0121] Each display unit is an area composed of multiple pixels on the display screen, where the display unit D 1 For area 4, D 2 For area 5, D 3 for zone 6. Each display unit can be switched among three display states of "red", "green" and "blue", respectively with S 1 , S 2 , S 3 To indicate that for the display unit set, there are 27 display modes:

[0122] S 1 S 1 S 1 , S 1 S 1 S 2 , S 1 S 1 S 3 , S 1 S 2 S 1 , S 1 S 2 S 2 , S 1 S 2 S 3 , S 1 S 3 S 1 , S 1 S 3 S 2 , S 1 S 3 S 3 ,

[0123] S 2 S 1 S 1 , S 2 S 1 S 2 , S 2 S 1 S 3 , S 2 S 2 S 1 , S 2 S 2 S 2 , S 2 S 2 S 3 , S 2 S 3 S 1 , S 2 S 3 S 2 , S 2 S 3 S 3 ,

[0124] S 3 S 1 S 1 , S 3 S 1 S 2 , S 3 S 1 S 3 , S 3 S 2 S 1 , S 3 S 2 S 2 , S 3 S 2 S 3 , S 3 S 3 S 1 , S 3 S 3...

Embodiment 3

[0174] Such as Figure 7 As shown, the set of display units consists of a display unit D 1The display unit is a color light-emitting diode 3. Theoretically, the color diode can emit light of countless colors, that is, it can have countless display states, but usually only select a part of the display that is easy to be scanned and recognized by the information receiving end according to needs. State, select "red", "green", "blue", "off" four display states in this embodiment, use S 1 , S 2 , S 3 , S 4 To indicate that these states are easy to identify and easy to control with a single-chip microcomputer. Then the set of display units has four display modes in total. In order to distinguish them from the display states, use {S 1}, {S 2}, {S 3}, {S 4}To represent.

[0175] In each cycle, the display mode of the display unit set is switched once, and the following four signals are defined according to the number of steps for switching the display state of each display un...

Abstract

The invention provides a dynamic image code generating method and device. A display unit set including at least one display unit is used to display a dynamic image code. The generating method comprises that original information is coded into one or multiple continuous basic information according to a preset original information coding rule, each basic information is coded into one or multiple continuous signals according to a preset basic information coding rule, and according to the coded signals, the display modes of the display unit set are switched in preset frequency. The original information is displayed via dynamic continuous image codes. The dynamic image codes are simple in images, can be adjusted flexibly according to requirements, occupy small space, can fully utilize corner areas of a display screen for display, and has low requirements for the display screen; even low-cost LEDs can be used for display; and protocols are simple, information carrying by the image codes can be changed flexibility, and the enforcement difficulty and cost are lower.

Description

technical field [0001] The invention belongs to the field of image codes, in particular to a method and device for generating dynamic and continuous image codes. Background technique [0002] Image codes can be seen everywhere in life, such as barcodes, two-dimensional codes, color three-dimensional codes, etc. The more complex the image of the image code is, the more information it can carry. For the convenience of description, only the two-dimensional code is used as a representative for description below. [0003] The two-dimensional code provides a way for the terminal to obtain information, and the information carried in the two-dimensional code can be read through the two-dimensional code scanning function on the mobile phone. QR codes can be displayed on paper by printing, or displayed on various display screens by means of image display. [0004] When the QR code is displayed on paper, the information carried by it is fixed, which will increase the difficulty of u...
