Please refer to fig. 1, which is a flowchart illustrating a method for editing a display image according to an embodiment of the present invention.
In one embodiment, an editing method for displaying an image includes the following steps:
step 110: the method comprises the steps of obtaining signal light on a display screen, wherein the signal light is light with loading frequency within a preset frequency range.
In this embodiment, the signal light is a light that flickers at a loading frequency, and the signal light is a signal light that can be carried by the signal light by flickering at the loading frequency. It should be noted that the loading frequency is a frequency or a frequency in the preset frequency range, that is, the loading frequency may be a frequency value in the preset frequency range, or may be a plurality of consecutive frequencies in the preset frequency range. It should be noted that, in this embodiment, the signal light on the display screen is light irradiated on the display screen, and the flicker frequency of the light is the loading frequency.
In one embodiment, the signal light is used for marking selected contents in the display image, and the selected contents are contents to be edited. In one embodiment, the signal light is emitted by a signal light emitting device, the loading frequency of the signal light is related to a signal generator in the signal light emitting device, and whether the signal light is a combined light signal is determined by the signal light emitting device, for example, the light emitted by the signal light emitting device only contains signal light with a preset frequency; for another example, the light emitted by the signal light emitting device is a combined light formed by combining a signal light with a preset frequency and a high-frequency laser, where a loading frequency of the signal light is different from a frequency of a laser signal, that is, a period of the signal light is different from a period of the laser light, that is, the signal light and the laser light are two incoherent light signals. In this way, due to the special frequency characteristics of the signal light, the signal light is easy to decode after being acquired, so that the acquisition of the signal light is facilitated, and further, the subsequent editing operation is facilitated to be executed according to the frequency of the signal light.
Step 120: and acquiring an editing instruction after receiving the signal light.
In an embodiment, a corresponding editing instruction is obtained according to the signal light, and the editing instruction is used for subsequently executing a corresponding editing operation. In this way, after receiving the loading frequency of the signal light, the video card obtains a corresponding editing instruction according to the loading frequency, and the loading frequency of the signal light is located within the preset frequency range, so that each loading frequency or each section of loading frequency corresponds to one editing instruction, so that the loading frequency of the signal light corresponds to the editing instruction one by one, that is, the execution of each editing instruction is related to the loading frequency of one signal light, that is, the specific operation of each editing instruction corresponds to the loading frequency of one signal light, thereby facilitating the subsequent accurate execution of editing operation on the image on the display screen.
In this embodiment, after the selected content in the image is displayed according to the signal light marker, the editing instruction is acquired.
Step 130: and editing the display image of the display screen according to the editing instruction.
In an embodiment, the editing instructions correspond to the signal lights, that is, each editing instruction corresponds to one signal light, that is, each signal light corresponds to one editing instruction, wherein loading frequencies of the signal lights also correspond, that is, each editing instruction corresponds to a loading frequency of one signal light, that is, each loading frequency of the signal light corresponds to one editing instruction. And sending the editing instructions to an execution unit, and acquiring the editing operation corresponding to each editing instruction according to the editing operation stored in an internal memory, so as to correspondingly edit the display image on the display screen, and further realize the modification of the image displayed on the display screen.
In an embodiment, the step 120 includes the following step, that is, after receiving the signal light, the step of acquiring the editing instruction includes: and after receiving the signal light, acquiring an editing signal, wherein carriers of the editing signal comprise ultrasonic waves, electromagnetic waves, Bluetooth and infrared light. And analyzing the editing signal to obtain the editing instruction.

The carrier of the editing signal and the signal light are different forms of signal carriers, in one embodiment, the editing signal is an ultrasonic signal, in one embodiment, the editing signal is an electromagnetic wave signal, in one embodiment, the editing signal is a bluetooth signal, and in one embodiment, the editing signal is an infrared signal. It is worth mentioning that the electromagnetic wave signal is a radio wave signal.
In this embodiment, the signal light is used to select the content to be edited in the display image, the editing signal is used to carry the editing instruction, the editing instruction is obtained by analyzing the editing signal, and the content to be edited in the selected display image can be edited according to the editing instruction.
For example, after the signal light is detected, the content to be edited in the display image is acquired according to the signal light, then, the ultrasonic signal is acquired, the ultrasonic signal is analyzed, the editing instruction is acquired, and the content to be edited in the selected display image is edited according to the editing instruction. Therefore, the content to be edited in the display image can be selected through the signal light, and the content to be edited is edited according to the editing instruction corresponding to the editing signal.
For example, when the carrier of the editing signal is an electromagnetic wave, and the frequency of the electromagnetic wave is different from the frequency of light for marking on the display screen, in this way, the electromagnetic wave for acquiring the editing instruction is irrelevant to the light for marking on the display screen, that is, the electromagnetic wave is independent from the signal light with the loading frequency in the preset frequency range, so that the electromagnetic wave of the editing instruction is conveniently acquired, the signal light is conveniently decoded, and the editing instruction is conveniently acquired. For the case that the carrier of the editing signal is ultrasonic, bluetooth or infrared light, the function is the same as above, and will not be described again here.
In an embodiment, the step 120 includes the following step, that is, after receiving the signal light, the step of acquiring the editing instruction includes: and analyzing the signal light to obtain the loading frequency of the signal light. And acquiring an editing instruction corresponding to the loading frequency according to the loading frequency.
In this embodiment, the signal light is not only used to select the content to be edited in the display image, but also used to carry the editing instruction. After the display screen acquires the signal light, the display screen analyzes the signal light, that is, decodes the encoded information carried by the signal light, so as to acquire important information in the signal light, for example, acquire the loading frequency of the signal light. Through the acquired loading frequency, the display screen carries out frequency distinguishing on the loading frequency, so that the acquired loading frequency is conveniently judged to be in which frequency interval in the preset frequency range, namely the editing instruction corresponding to the loading frequency is judged by acquiring the numerical value of the loading frequency, the acquired editing instruction corresponds to the loading frequency, and the editing instruction is conveniently and accurately acquired.
In one embodiment, step 110 includes the following steps, after acquiring the signal light on the display screen: and acquiring selected contents in the display image according to the movement of the signal light on the display screen.
One embodiment is that the selected content within the displayed image is selected in accordance with the movement of the signal light on the display screen. According to the movement of the signal light on the display screen, the selected content in the display image is selected based on the mapping relation between the display screen and the display image.
In this embodiment, since the display screen is used for displaying the display image, a corresponding mapping relationship is established between the display screen and the display image, and the coordinate system on the display screen corresponds to the coordinate system of the display image, so that one point on the display screen corresponds to one point on the display image. When the signal light moves on the display screen, the light spot of the signal light on the display screen corresponds to different contents in the display image, so that the signal light moves on the display screen to select a plurality of selected contents in the display image, wherein the selected contents are contents to be edited.
It should be noted that the display image may also be referred to as a display screen or a display page, the content displayed in the display image may be a text, a picture, a symbol, a file, or the like, and the content displayed in the display image may not be limited to the text, the picture, the symbol, or the file described above, and may also include application software or a display interface in the application software.
The signal light is mapped with a corresponding light spot on the display screen, namely a coordinate point irradiated by the signal light on the display screen, and the light spot of the signal light on the display screen is equivalent to a cursor point of a mouse. When the carrier frequency in the signal light is within a preset frequency range, the signal light moves in a certain direction, so that a motion track is left on the display screen by the signal light, an image displayed on the display screen corresponds to the motion track, the display screen determines the display image as selected content, and the display image in the selected content is used for subsequent image editing.
In one embodiment, the step of acquiring the selected content in the display image according to the movement of the signal light on the display screen comprises: and acquiring selected content corresponding to the motion track in the display image according to the motion track formed by the movement of the signal light on the display screen. The signal light is received by the display screen, that is, an editing signal of the signal light is received by the display screen, the display screen forms a corresponding motion track according to the receiving position of the signal light, the motion track corresponds to a display image on the display screen, and the selected display image is defined as selected content, that is, content to be edited subsequently.
The step of editing the display image of the display screen according to the editing instruction comprises the following steps: and editing the selected content in the display image according to the editing instruction. When the editing instruction is acquired by the display screen, the display screen correspondingly decodes, the display screen executes the corresponding editing instruction according to the editing instruction, and the display screen edits the image on the editing track according to the editing instruction, namely edits the selected content on the display screen.
In one embodiment, before the acquiring the selected content in the display image according to the movement of the signal light on the display screen, the acquiring the signal light on the display screen includes: and acquiring the coordinate position of the signal light on the display screen.
The signal light is mapped to the light spot on the display screen, the light spot corresponds to the coordinate, when the signal light moves, the light spot forms a moving track on the display screen, the moving track corresponds to the coordinate, and the coordinate position is convenient for obtaining the moving track subsequently. The coordinate formed by the signal light on the display screen is completed by two signal receiving modules, the two signal receiving modules are separately arranged, and the light signal acquisition directions of the two signal receiving modules are mutually vertical.
In an embodiment, the display screen is a rectangular screen, two vertical edges of the display screen are respectively provided with one signal receiving module, and the signal receiving modules are located at the middle points of the edges of the display screen, for example, one of the signal receiving modules is arranged at the middle point of one long edge of the display screen, and the other signal receiving module is arranged at the middle point of one short edge of the display screen. In this way, the two signal receiving modules respectively acquire two coordinate axes of the signal light on the display screen, and the specific position of the signal light on the display screen is determined through the coordinates of the two coordinate axes, that is, the coordinate position of the signal light on the display screen is acquired, so that the moving track of the signal light on the display screen is conveniently determined. The signal receiving module comprises a camera, and the camera acquires the light emitting frequency of the signal light through a photosensitive film of the camera, so that the coordinate position of the signal light on the display screen is acquired.
In one embodiment, the acquiring the selected content in the display image according to the movement of the signal light on the display screen further includes: and acquiring selected contents in the display image according to the change of the coordinate position of the signal light on the display screen.
The signal receiving module is used for sequentially connecting the coordinate positions of the signal light on the display screen according to the coordinate positions of the signal light on the display screen, namely, each coordinate position of the signal light on the display screen is connected in sequence, so that a continuous curve is formed, the curve is a moving track of the signal light on the display screen, an area where the moving track of the signal light on the display screen passes is used as selected content, namely, an area covered by the signal light moving on the display screen is an editable area, and the editable area is used as an editing area for editing a display image of the display screen according to the editing instruction. In this way, according to the selected content formed by moving the signal light on the display screen, the display screen performs corresponding editing operation on the displayed content in combination with an editing instruction.
In an embodiment, different loading frequencies have different editing instructions, and each editing instruction performs a corresponding editing operation on a selected content in an image displayed on the display screen.
For example, the predetermined frequency range is 35HZ to 300 HZ. When the loading frequency range is 30 HZ-40 HZ, the editing instruction corresponding to the loading frequency is a background color changing instruction, and text background color changing is carried out on the selected content in the display image on the display screen through the text background color changing instruction; for another example, when the range of the loading frequency is 60HZ to 70HZ, the editing instruction corresponding to the loading frequency is a font color changing instruction, and font color change is performed on the selected content in the display image on the display screen through the font color changing instruction; for another example, when the loading frequency ranges from 80HZ to 90HZ, the editing instruction corresponding to the loading frequency is a deletion instruction, and the content deletion instruction is used for deleting the selected content in the display image on the display screen; for another example, when the loading frequency is in the range of 110HZ to 120HZ, the editing instruction corresponding to the loading frequency is a marking instruction, and text dot mark is performed on the selected content in the display image on the display screen through the text dot mark instruction; for another example, when the loading frequency range is 165HZ to 175HZ, the editing instruction corresponding to the loading frequency is a saving instruction, and the selected content in the display image on the display screen is saved through the saving instruction; for another example, when the loading frequency ranges from 210HZ to 220HZ, the editing instruction corresponding to the loading frequency is a cancel instruction, and the selected content in the display image on the display screen is canceled through the cancel instruction.
In an embodiment, when the loading frequency ranges from 60HZ to 90HZ, three different editing instructions, that is, a change instruction of a text background color, a font color change instruction, and a deletion instruction of content, are provided, and the commonality between the three instructions is achieved by changing the color. The color changing mode is to change the gray values of the text background and the font, and increase or decrease a first preset gray value to the gray values of the text background and the font, for example, the first preset gray value is 50-70; as another example, the first preset gradation is 60. When the gray value of the text background and the font after increasing the first preset gray exceeds the gray range, the image control device increases or decreases twice the first preset gray to the gray value of the text background and the font, for example, when the gray value of the text background and the font after increasing the first preset gray is greater than the maximum gray, that is, the gray value of the text background and the font after increasing the first preset gray is greater than 255, the gray value of the text background and the font after increasing the first preset gray is decreased by two first preset grays; for another example, when the gray value of the text background and the font after being reduced by the first preset gray level is smaller than the minimum gray level, that is, the gray value of the text background and the font after being reduced by the first preset gray level is smaller than 0, the image control apparatus increases two first preset gray levels to the gray value of the text background and the font after being reduced by the first preset gray level.
In one embodiment, when the loading frequency is in a range of 110HZ to 120HZ, the editing instruction is a dot mark instruction of a text, and a second preset gray level is added or reduced to a gray level around a text image, that is, an edge gray level of the selected content in a display image displayed on the display screen is added or reduced, where the second preset gray level is, for example, 90 to 110; as another example, the second preset gradation is 100. When the gray value of the text background and the font after the second preset gray is added exceeds the gray range, the image control device increases or decreases twice the second preset gray to the gray value of the text image edge, for example, when the gray value of the text image edge after the second preset gray is added is greater than the maximum gray, that is, the gray value of the text image edge after the second preset gray is added is greater than 255, the gray value of the text image edge after the second preset gray is added is decreased by two second preset grays; for another example, when the gray value of the text image edge after the second preset gray is reduced is smaller than the minimum gray, that is, the gray value of the text image edge after the second preset gray is reduced is smaller than 0, the image control device increases two second preset grays to the gray value of the text image edge after the second preset gray is reduced.
In an embodiment, when the loading frequency ranges from 165HZ to 175HZ, the editing instruction is a saving instruction, and the image control apparatus saves the whole display page of the image displayed on the display screen.
In an embodiment, when the loading frequency ranges from 210HZ to 220HZ, the editing instruction is a cancel instruction, and the image control apparatus cancels a previous editing operation on the image displayed on the display screen, that is, returns to a previous editing instruction, that is, the display screen displays the image displayed by the previous editing instruction.
In one embodiment, the signal light includes a laser for selecting a content to be edited and a light with a loading frequency within a preset frequency range, wherein the laser is determined by a signal light emitting device according to a required color, and lasers with different colors are used in different use environments, for example, the laser includes a green laser; as another example, the laser includes a red laser; as another example, the laser includes a blue laser. Because the laser has a specific color, when the image color of the display screen is a light color system, the instruction input module on the signal light emitting device is controlled to emit red laser or blue laser; and when the image color of the display screen is a dark color system, the blue laser is emitted by controlling an instruction input module on the signal light emitting device. Therefore, a large hue difference exists between the color of the laser and the color of the image displayed on the display screen, so that an operator and a viewer can conveniently and accurately find the laser point of the laser on the display screen, and the specific position of the laser on the display screen can be found out accurately.
Because the laser is mixed with the optical signal with the loading frequency within the preset frequency range, the laser is received by the display screen, and when the coding module in the display screen decodes that the laser contains the light with the loading frequency within the preset frequency range, the coding module acquires the loading frequency of the signal light. Since the loading frequency is within the preset frequency range, the size of the preset frequency range determines the number of the editing instructions corresponding to the loading frequency, and in order to avoid stroboflash of the signal light within the preset frequency range to the operator and the viewer, the frequency of the laser and the preset frequency are both greater than the minimum human eye identification frequency, for example, the range of the laser frequency is 3.846 × 1014HZ～7.895×1014HZ; for another example, the predetermined frequency ranges from 35HZ to 300 HZ. Therefore, the frequency of the laser is far greater than the minimum identification frequency of human eyes, so that the laser presents a continuous state for an operator and an observer in the emitting and moving processes, and the frequency of the optical signal with the loading frequency in the preset frequency range is greater than 24HZ, namely the frequency of the optical signal with the loading frequency in the preset frequency range is greater than the minimum identification frequency of human eyes, namely the optical signal with the loading frequency in the preset frequency range presents a continuous state for the operator and the observer when following the laser, so that the situation that the composite optical signal of the optical signal with the loading frequency in the preset frequency range causes stroboflash to the operator and the observer is avoided, and the operator and the observer can conveniently obtain the moving situation of the composite optical signal on the display screen.
In one embodiment, the loading frequency corresponds to different editing instructions according to different frequency intervals in the preset frequency, for example, when the loading frequency is in a range of 30HZ to 40HZ, the editing instructions are text background color changing instructions; for another example, when the loading frequency ranges from 60HZ to 70HZ, the editing instruction is a font color changing instruction; for another example, when the loading frequency ranges from 80HZ to 90HZ, the editing instruction is a content deletion instruction; for another example, when the loading frequency ranges from 110HZ to 120HZ, the editing instruction is a text dot mark instruction; for another example, when the loading frequency ranges from 165HZ to 175HZ, the edit instruction is a save instruction; for another example, when the loading frequency ranges from 210HZ to 220HZ, the edit instruction is a cancel instruction. In this way, the preset frequency is divided into a plurality of frequency intervals, different editing instructions are obtained by changing the loading frequency of the signal light, that is, corresponding editing instructions are obtained according to the obtained loading frequency, so that different editing operations can be executed by changing the interval of the signal light in the preset frequency, and further, the image displayed by the display screen can be modified correspondingly. According to the method for editing the display image, the signal light with the loading frequency within the preset frequency range is received, the corresponding editing instruction is obtained according to the loading frequency, and then the display image on the display screen is edited according to the editing instruction, so that the corresponding editing operation can be executed after the loading signal light with the specific frequency is received, and the image displayed on the display screen can be modified conveniently.
