[0002] At present, the imaging components of projection equipment (such as display panels or digital micromirror devices (DMD)) contain a mirror array composed of tens of millions of tiny mirrors, each of which corresponds to a pixel. When the projection device receives the image to be projected, it generates the three primary colors (i.e., red / green / blue (RGB)) data of each pixel according to the image to be projected, and then generates corresponding light in a certain order through green light-emitting diodes, red light-emitting diodes, and blue light-emitting diodes to project to all mirrors. The imaging device can control each mirror to reflect the required light and reflect the unnecessary light to other positions, thereby completing the projection.

[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.
[0051] At present, the imaging components of projection equipment (such as display panels or digital micromirror devices (DMD)) contain a mirror array composed of tens of millions of tiny mirrors, each of which corresponds to a pixel. When the projection device receives the image to be projected, it generates the three primary colors (i.e., red / green / blue (RGB)) data of each pixel according to the image to be projected, and then generates corresponding light in a certain order through green light-emitting diodes, red light-emitting diodes, and blue light-emitting diodes to project to all mirrors. The imaging device can control each mirror to reflect the required light and reflect the unnecessary light to other positions, thereby completing the projection.
[0052] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of traditional projection equipment. Figure 1 As shown, a conventional projection device may include: a processor, a light emitting component, and an imaging component;
[0053] The light-emitting component may be a component for emitting optical fibers, and may be composed of light-emitting diodes corresponding to three primary colors, that is, the light-emitting component may include: a red light-emitting diode (i.e. Figure 1 R LED), green light emitting diode (i.e. Figure 1 GLED) and blue light emitting diode (i.e. Figure 1 In the example, a red LED is used to generate red light, a green LED is used to generate green light, and a blue LED is used to generate blue light; at the same time, in order to drive the light-emitting component, a light-emitting driving component (i.e. Figure 1 In the embodiment of the present invention, the processor is connected to the light-emitting driving component, and the light-emitting driving component is connected to the light-emitting component. The processor and the light-emitting driving component can be connected by means of a serial bus interface (Inter-Integrated Circuit, I2C), a serial peripheral interface (Serial Peripheral Interface, SPI) or a pulse width modulation (Pulse Width Modulation, PWM), etc., which is not limited in this embodiment.
[0054] like Figure 1 As shown, the processor and the imaging component may also be connected, specifically through a mobile industry processor interface (MIPI). Of course, they may also be connected through other methods, which are not limited in this embodiment.
[0055] It should also be noted that the processor may be formed by a field programmable gate array (FPGA), or other processing chips, which is not limited in this embodiment. Figure 1 The imaging component may be provided with a plurality of tiny mirrors, each of which corresponds to a pixel.
[0056] In actual use, the processor can receive the image to be projected, and determine the three primary color data corresponding to each micromirror according to the image to be projected, that is, determine the RGB value corresponding to each pixel. The three primary color data is transmitted to the imaging component, and the imaging component can determine the opening or closing time of each mirror according to the three primary color data, and generate a synchronization signal (i.e. Figure 1 The processor generates a light-emitting signal according to the RGB value and transmits it to the LED driver. The LED driver controls each light-emitting diode to light up in sequence according to the synchronization signal and the light-emitting signal. For example, red is lit at time T1, green is lit at time T2, blue is lit at time T3, red is lit again at time T4, green is lit again at time T5, and blue is lit again at time T6. The light generated by the light-emitting diode can be projected onto each mirror surface of the imaging component. The imaging component controls each mirror surface according to the determined switching or closing time of each mirror surface, thereby completing the projection.
[0057] However, since the light-emitting component projects light to the entire imaging device and is lit in a fixed order, when there is some light that does not need to be projected in the image to be projected, the existing method only controls the mirror at the corresponding position in the imaging device to reflect the light of that color to other positions, and the light-emitting component still keeps emitting light, resulting in high energy consumption. For example, if a certain pixel only needs to project red light, then green and blue are not needed. The existing method is that when emitting green and blue light, the imaging component controls the mirror corresponding to the pixel to be in a closed state, reflects the green and blue light to other positions, and then turns on the mirror to project when receiving red light. Therefore, when a certain pixel does not need a certain color, the light-emitting component of that color is still in a light-emitting state, resulting in high energy consumption.
[0058] Therefore, in order to solve the above defects, the present embodiment provides a projection method, which is applied to a projection device, wherein the projection device at least includes: a green light-emitting component, a red light-emitting component, a blue light-emitting component, an imaging component with a plurality of mirrors, and a reflective component for reflecting the light emitted by each light-emitting component to each mirror in sequence. Since the present embodiment is provided with a reflective component in the projection device that can reflect the light emitted by the light-emitting component to each mirror in sequence, when receiving the image to be projected, the three primary color data of each pixel can be determined according to the image to be projected, and the target primary color that does not need to be projected on each mirror can be determined according to each three primary color data, and then the reflective component can be controlled to deflect, and when the reflective component deflects to the position corresponding to the current mirror, the light-emitting component corresponding to the target primary color is controlled to stop emitting light. Compared with the existing method in which the light-emitting component still keeps emitting light when a certain color is not needed, the present embodiment can control the corresponding light-emitting component to stop emitting light when a certain color is not needed, thereby reducing energy consumption.
[0059] For ease of understanding, the following combination Figures 2 to 9 The projection method provided in the embodiment of the present application is specifically introduced.
[0060] Reference Figure 2 , Figure 2 Schematic diagram of the process of the first embodiment of the projection method of the present application, the first embodiment of the projection method of the present application is proposed, such as Figure 2 As shown, in this embodiment, the method is applied to a projection device, which includes at least: a green light-emitting component, a red light-emitting component, a blue light-emitting component, an imaging component with a plurality of mirrors, and a reflecting component for reflecting the light emitted by each light-emitting component to each of the mirrors in turn.
[0061] Reference Figure 3 , Figure 3 This is a schematic diagram of the structure of the projection device in the first embodiment of the projection method of this application. Figure 3As shown, the processor, light-emitting component, and imaging component in this embodiment are all consistent with the traditional ones, and this embodiment will not be repeated. The green light-emitting component in this embodiment can be a green light-emitting diode, the red light-emitting component can be a red light-emitting diode, and the blue light-emitting component can be a blue light-emitting diode. It should be emphasized that in this embodiment, a reflective component is additionally arranged on the optical path between the light-emitting component and the imaging component, and the reflective component can reflect the light emitted by the light-emitting component to each mirror surface on the imaging component in sequence. The reflective component in this embodiment may include a reflective driving unit and a reflective unit, wherein the reflective driving unit may be a unit for driving the reflective unit, and the reflective unit may be a unit for reflecting light to each mirror surface. This embodiment uses a micro-electro-mechanical system (MEMS) for description, and the driving reflective unit is a MEMS drive. Then, the light can be reflected to each mirror surface in sequence through MEMS, which also shows that this embodiment reflects a kind of light to each mirror surface in sequence, instead of the traditional method of projecting a kind of light to all mirror surfaces.
[0062] based on Figure 3 As a result, the projection method of this embodiment includes:
[0063] Step S10: when receiving the image to be projected, determining the three primary color data corresponding to each pixel in the image to be projected.
[0064] It is understandable that the method of this embodiment can be applied to a scene for projection, and of course can also be applied to other scenes that require display, and this embodiment does not limit this. The execution subject of this embodiment can be a projection device with projection, data processing, network communication and program running functions, such as a projector, or other devices that can achieve the same or similar functions. Specifically, the execution subject of this embodiment can be a processor in the projection device. This embodiment and the following embodiments adopt Figure 3 The processor in is described as the execution subject.
[0065] It should be understood that the above-mentioned image to be projected can be any image that needs to be projected, and can be obtained by sending it from other electronic devices. Figure 3 As shown, the projection device in this embodiment may also include: a bridge (i.e. Figure 3 Bridge) and a transmission interface, which can use a USB Type-C interface (i.e. Figure 3 Of course, other interfaces may also be used, and this embodiment does not limit this.
[0066] The processor in this embodiment can be connected to the bridge, specifically, through MIPI, and the bridge is then connected to the external electronic device through the transmission interface to receive the image to be projected, wherein the bridge and the transmission interface can be connected in the form of a display port (DisplayPort, DP), of course, other methods can also be used, and this embodiment does not limit this. The above-mentioned electronic device can be a device that can generate the image to be projected, such as a personal computer (i.e. Figure 3 PC) etc.
[0067] In actual use, the external electronic device can transmit the image to be projected to the bridge through the transmission interface, and the bridge then transmits it to the processor.
[0068] As another implementation, the image to be projected may be directly stored in the projection device in this embodiment, thereby eliminating the need to input the image from an external electronic device.
[0069] It should be noted that the three primary color data may be data corresponding to the RGB value of each pixel in the image to be projected. In a specific implementation, the external electronic device may transmit the image to be projected to the processor in the form of a digital signal, and after receiving the image to be projected, the processor may analyze it to obtain the three primary color data corresponding to each pixel.
[0070] Step S20: determining the target primary colors that do not need to be projected corresponding to each of the mirror surfaces according to the three primary color data.
[0071] It is understandable that the target primary color may be the color of the mirror corresponding to the pixel when it is in a closed state when projecting the image to be projected, that is, the color that does not require the mirror for projection.
[0072] Specifically, in order to determine the target primary color, in this embodiment, the step S20 includes:
[0073] Step S21: determining the three primary color values of each pixel according to each of the three primary color data;
[0074] Step S22: using the primary colors whose three primary color values are not higher than the corresponding preset primary color thresholds as the target primary colors that do not need to be projected corresponding to each of the mirror surfaces.
[0075] It should be understood that the above three primary color values may be RGB values corresponding to the pixels. The above preset primary color threshold may be a value used to determine whether the color needs to be projected. In this embodiment, different primary colors may be set with different preset primary color thresholds, and of course, the same preset primary color threshold may also be set. In this embodiment, 0 is used for illustration.
[0076] That is, in actual use, after the processor determines the RGB value of each pixel, it can compare the red value (i.e., R value) with the corresponding preset primary color threshold, the green value (i.e., G value) with the corresponding preset primary color threshold, and the blue value (i.e., B value) with the corresponding preset primary color threshold. According to the comparison result, the primary color that is not higher than the preset primary color threshold is used as the target primary color, so that the mirror does not need to project the primary color.
[0077] For example, if the R value corresponding to a pixel is 255, the G value is 0, and the B value is 0, the above-mentioned preset primary color thresholds are all set to 0, and then after the above-mentioned comparison, it can be determined that only the R value exists higher than the preset primary color threshold, and then it can be determined that the mirror corresponding to the pixel does not need to project the green and blue primary colors, but only needs to project red, that is, the above-mentioned target primary colors are green and blue.
[0078] Step S30: Control the reflective component to deflect, and when the reflective component deflects to a position corresponding to the current mirror surface, control the light-emitting component corresponding to the target primary color to stop emitting light.
[0079] After the target primary color is determined, projection can begin. The processor can generate a light-emitting signal and a deflection signal according to the target primary color corresponding to each mirror, transmit the light-emitting signal to the LED driver, and the LED driver drives the light-emitting component to emit light, and transmits the deflection signal (i.e. Figure 3 The MEMS mirror motion control) is transmitted to the MEMS driver, and the MEMS driver then drives the MEMS to deflect.
[0080] Specifically, the MEMS driver can deflect according to the preset deflection mode according to the deflection signal. In this embodiment, the deflection mode from the upper left corner mirror to the lower right corner mirror can be used as the preset deflection mode. Of course, other deflection modes are also possible, and this embodiment does not limit this.
[0081] For LED driving, the light-emitting component can be driven to emit light according to the light-emitting signal, and when the processor controls the MEMS to deflect to the current mirror, the light-emitting component can be controlled not to emit light corresponding to the target primary color of the current mirror, thereby achieving the purpose of reducing energy consumption.
[0082] For example, if for a certain mirror, the light-emitting component emits light in a preset order of red, green, and blue, when the mirror does not need green light, the traditional method is to set the mirror to a closed state when the green light is on, and then reflect the green light to other positions; while the method provided by this embodiment is to control the green light-emitting diode not to emit light when the green light should be on. Under the premise of the same brightness, this embodiment achieves the purpose of reducing energy consumption by controlling the diode not to emit light at some times.
[0083] In this embodiment, a reflective component is provided in the projection device, which can reflect the light emitted by the light-emitting component to each mirror in sequence. When receiving the image to be projected, the three primary color data of each pixel can be determined according to the image to be projected, and the target primary color that does not need to be projected on each mirror can be determined according to each three primary color data, and then the reflective component is controlled to deflect, and when the reflective component deflects to the position corresponding to the current mirror, the light-emitting component corresponding to the target primary color is controlled to stop emitting light. Compared with the existing light-emitting component that keeps emitting light when a certain color is not needed, this embodiment can control the corresponding light-emitting component to stop emitting light when a certain color is not needed, thereby reducing energy consumption.
[0084] Reference Figure 4 , Figure 4 This is a flow chart of the second embodiment of the projection method of the present application. Based on the above-mentioned first embodiment, the second embodiment of the projection method of the present application is proposed.
[0085] In order to further reduce energy consumption, Figure 4 As shown, in this embodiment, the step of determining the three primary color data corresponding to each pixel in the image to be projected includes:
[0086] Step S11: determining the three primary color data corresponding to each pixel of the image to be projected in each projection subarea according to the preset divided areas.
[0087] It should be noted that the above-mentioned preset divided areas can be areas where pixels are pre-divided. In this embodiment, each pixel can be pre-divided into a number of areas, and the result of the division is called the above-mentioned projection partition. Specifically, when dividing, the present embodiment can be divided in an equal manner, that is, the size of each projection partition is the same. Of course, it can also be divided in an unequal manner, that is, the size of each projection partition can be different. This embodiment uses an equal division method for description. And the specific number of projection partitions can also be set according to actual conditions. This embodiment uses m*n projection partitions for description, refer to Figure 5 , Figure 5 This is a schematic diagram of projection partitions in the second embodiment of the projection method of the present application.
[0088] like Figure 5 As shown, in this embodiment, each pixel can be pre-divided into m*n projection partitions (i.e. Figure 5 In the example of dividing the PC original picture into screen effects), each projection partition can be numbered, specifically from the upper left corner to the lower right corner, and are recorded as (11, 12, 13..., mn).
[0089] In actual use, after the processor receives the image to be projected, it can determine the three primary color data corresponding to each pixel in each projection partition.
[0090] The above step S20 includes:
[0091] Step S21: determining the target primary color that does not need to be projected corresponding to each mirror surface in each projection partition according to each of the three primary color data.
[0092] After obtaining the three primary color data corresponding to each pixel in each projection partition, the RGB values of the three primary color data can be compared with the corresponding preset primary color thresholds to determine the target primary color corresponding to each projection partition. That is, determine whether the R value of each pixel in each projection partition is not higher than 0, whether the G value is not higher than 0, or whether the B value is not higher than 0. If the G values of the pixels in a certain projection partition are all 0, it can be said that the target primary color of the projection partition is green. Similarly, if the B values of the pixels in a certain projection partition are all 0, it can be said that the target primary color of the projection partition is blue. If the R values of the pixels in a certain projection partition are all 0, it can be said that the target primary color of the projection partition is red.
[0093] The step of controlling the reflective component to deflect comprises:
[0094] Step S31: selecting a non-black partition from each of the projection partitions according to the target primary color, and controlling the reflective component to deflect in the non-black partition.
[0095] It is understandable that the non-black partitions mentioned above may be projection partitions where there is no black. After obtaining the target primary colors of each projection partition, the processor of this embodiment may determine whether there is a projection partition whose target primary colors include red, green and blue; if so, the projection partition may be used as a black partition, and the remaining projection partitions may be the non-black partitions mentioned above, because when the projection displays black, the mirror is in a closed state for the projected red light, green light and blue light, that is, they are all reflected to other positions.
[0096] After selecting the non-black partition, the processor only controls the reflective component to deflect within the non-black partition when controlling the reflective component to reflect. The reflective component of the black partition does not need to be deflected to the corresponding position, and there is no light projection in the black partition. Therefore, it can reduce energy consumption while achieving the projection of black, and can make the black better than the traditional display of black.
[0097] By way of example, this embodiment is described using the following two situations:
[0098] Case 1: Reference Figure 6 , Figure 6 In the second embodiment of the projection method of this application, only the green schematic diagram is required, such as Figure 6As shown, when it is determined according to the three primary color data that the target primary colors that do not need to be projected in all projection partitions are red and blue, that is, only green needs to be projected, the processor can control the reflective component to deflect from the upper left corner to the lower right corner in sequence, and control the red light-emitting component and the blue light-emitting component not to emit light, and obtain Figure 6 The projection effect shown (i.e. Figure 6 (Figure 2-3).
[0099] Case 2: Reference Figure 7 , Figure 7 This is a schematic diagram of the second embodiment of the projection method of this application, in which only part of the image is green and the rest is black. Figure 7 As shown, when the upper right corner (i.e. Figure 7 The target primary colors that do not need to be projected in the projection partitions 1..., n, 2... and 2n) are red and blue, and the target primary colors that do not need to be projected in the remaining projection partitions are red, green and blue. Then the processor can determine that the area in the upper right corner is the above-mentioned non-black partition, and the rest are black partitions. Then, during projection, the processor can only control the reflective component to deflect from the upper left corner of the non-black partition to the lower right corner of the non-black partition in sequence within the non-black partition in the upper right corner, and control the red light-emitting component and the blue light-emitting component not to emit light. For the remaining black partitions, the reflective component does not reflect, and the image can be obtained. Figure 7 The projection effect shown (i.e. Figure 7 The invention can realize the projection of black while reducing energy consumption, and can make the black effect better than the traditional display black.
[0100] Reference Figure 8 , Figure 8 This is a flow chart of the third embodiment of the projection method of the present application. Based on the above embodiments, the third embodiment of the projection method of the present application is proposed.
[0101] In order to make the reflective component deflect in the non-black partition, in this embodiment, Figure 8 As shown, the step of controlling the reflective component to deflect in the non-black partition includes:
[0102] Step S311: determining a deflection area of the reflective component according to the non-black partition;
[0103] Step S312: Determine control parameters of the reflective component based on the deflection area.
[0104] It should be noted that the above-mentioned deflection area may be an area corresponding to a non-black partition where the reflective component projects light only. The above-mentioned control parameters may be parameters for controlling the reflective component to deflect in the deflection area, and may include but are not limited to angle parameters for reflecting light to each mirror surface in the deflection area, and time parameters for each deflection.
[0105] In this embodiment, in order to determine the control parameters, the above step S312 includes:
[0106] The lighting time of each of the light-emitting components is determined according to the deflection area and the target primary color; and the control parameter of the reflective component is determined based on the deflection area and each of the lighting times.
[0107] It is understandable that the above-mentioned lighting time may be the time when each light-emitting component emits light.
[0108] In actual use, based on Figure 7 To illustrate, when the processor determines that the non-black partition is the area in the upper right corner, it can be determined based on the non-black partition that the reflective component only needs to be deflected in the area in the upper right corner, and then the area is used as the deflection area of the reflective component; after determining the deflection area, the lighting time corresponding to each light-emitting component can be determined based on the deflection area and the corresponding target primary color (red and blue), that is, keep the red light off at time T1, light up the green light at time T2, keep the blue light off at time T3, keep the red light off at time T4, light up the green light again at time T5, and keep the blue light off at time T6;
[0109] It should be emphasized that when the processor determines the lighting time of each light-emitting component, it can also be determined by the synchronization signal of the imaging component, so that the whole process is based on synchronization, such as Figure 3 As shown, the imaging component in this embodiment can be connected to the processor. After the processor transmits the generated three-primary color data to the imaging component, the imaging component can feed back a synchronization signal to the processor.
[0110] After the lighting time of each light-emitting component is obtained, the control parameter of the reflective component can be determined according to the lighting time and the deflection area. The specific process is the above-mentioned step of determining the control parameter of the reflective component based on the deflection area and each lighting time, including:
[0111] Determine the deflection angle of the reflective component at each lighting moment; and determine the control parameter of the reflective component based on the deflection area and each deflection angle.
[0112] In actual use, after the processor determines the lighting time of each light-emitting component, it can determine the deflection angle of the deflection component at each lighting time, for example, how many degrees to deflect at time T1, how many degrees to deflect at time T2, etc. After the deflection angle is obtained, the control parameter can be generated according to the deflection area and the deflection angle.
[0113] Step S313: controlling the reflective component to deflect in the non-black partition according to the control parameters.
[0114] After obtaining the control parameters, the processor can control the reflective component to deflect only in the non-black partition according to the control parameters. At the same time, when the reflective component deflects to the position corresponding to the current mirror in the non-black partition, the target primary color corresponding to the current mirror is controlled not to emit light, thereby achieving the purpose of reducing energy consumption.
[0115] Furthermore, in order to make the entire non-black partition display uniform, in this embodiment, when the reflective component deflects in the non-black partition, the movement period of the reflective component is an integer multiple of the number of pixels in the non-black partition.
[0116] It can be understood that the above movement period can be a period in which the reflective component deflects the entire non-black area.
[0117] Before the processor controls the reflective component to deflect, the number of pixels in the non-black partition (that is, the number of mirrors) can be determined first, and then an integer multiple of the number of pixels can be used as the movement period of the reflective component, where the integer multiple can be an integer multiple greater than or equal to 1, and can be set according to actual conditions. This embodiment does not limit this.
[0118] In addition, an embodiment of the present application further provides a storage medium, on which a projection program is stored. When the projection program is executed by a processor, the projection method as described above is implemented.
[0119] In addition, an embodiment of the present application further provides a projection device, the projection device comprising: a processor, a green light-emitting component, a red light-emitting component, a blue light-emitting component, an imaging component with a plurality of mirrors, and a reflecting component for sequentially reflecting the light emitted by each light-emitting component to each of the mirrors, the processor being respectively connected to the green light-emitting component, the red light-emitting component, the blue light-emitting component, the imaging component, and the reflecting component;
[0120] The processor is used to determine the three primary color data corresponding to each pixel in the image to be projected when receiving the image to be projected;
[0121] The processor is further used to determine the target primary color that does not need to be projected corresponding to each mirror surface according to each of the three primary color data;
[0122] The processor is further used to control the reflective component to deflect, and when the reflective component deflects to a position corresponding to the current mirror surface, control the light-emitting component corresponding to the target primary color to stop emitting light.

Compared with the existing light-emitting component that keeps emitting light when a certain color is not needed, this embodiment can control the corresponding light-emitting component to stop emitting light when a certain color is not needed, thereby reducing energy consumption.
