Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Referring to fig. 1, a schematic flow chart of a picture adjustment method according to an embodiment of the present invention is shown, where the picture adjustment method can be applied to a picture adjustment apparatus including a microprocessor and a photosensor, and as shown in fig. 1, the picture adjustment method can include the following steps:
it should be noted that, in the embodiment of the present invention, the picture adjusting apparatus may be integrated into a device to be adjusted (an image display device), or may be deployed independently, and is connected to the device to be adjusted in an external manner, so as to implement control of picture adjustment of the device to be adjusted.
In the embodiment of the invention, the image adjusting device can acquire the intensity of the outside light through the photosensitive sensor and send the acquired intensity of the outside light to the microprocessor.
In one embodiment of the present invention, the photosensitive sensor may be disposed on a frame of a display screen of the device to be conditioned, a back surface of the device to be conditioned, or a side surface of the device to be conditioned.
In this embodiment, to avoid light interference when the image display screen of the image display device plays an image, the light sensor may be disposed at a position where light emitted by the image display screen cannot be irradiated when the image display screen plays an image, such as a frame of the image display screen of the device to be adjusted, a back surface of the device to be adjusted, or a side surface of the device to be adjusted.
In another embodiment of the present invention, when the device to be regulated is a projection display device (such as a projector, a laser television, etc., hereinafter, the projector is taken as an example), the photosensitive sensor may be disposed inside the display screen and the frame of the display screen of the device to be regulated.
In this embodiment, when the device to be adjusted is a projector, the photosensitive sensors may be disposed inside the frame of the development screen and the development screen of the device to be adjusted, so that the microprocessor may determine the area of the development screen irradiated by the external light according to the acquisition condition of the intensity of the external light by each photosensitive sensor, thereby realizing the picture adjustment of the local area of the development screen.
It should be noted that, in this embodiment, when the projector projects an image onto the display screen, light emitted by the projector may affect detection of the photosensitive sensor in the display screen to external light, and therefore, when the photosensitive sensor is disposed in the display screen, the projector needs to send an off-light picture to the display screen when image adjustment is needed, so as to prevent the light emitted by the projector from interfering with detection of the photosensitive sensor in the display screen to the external light, and improve accuracy of detection of the photosensitive sensor in the display screen to the external light.
The projector may send an off-light picture to the display screen when receiving an off-light picture sending instruction sent by the remote controller, or the projector may send an off-light picture to the display screen periodically, for example, sending one off-light picture to the display screen every 5 minutes.
Correspondingly, when the projector needs to send off light pictures, an external light detection notification message can be sent to the microprocessor of the picture adjusting device; when receiving the external light detection notification message, the microprocessor may send an external light detection trigger instruction to the photosensor, so that when receiving the external light detection trigger instruction, the photosensor acquires the intensity of the external light, and sends the acquired intensity of the external light to the microprocessor.
And 102, determining picture adjusting parameters by the microprocessor according to the intensity of the external light acquired by the photosensitive sensor, and sending a picture adjusting instruction carrying the picture adjusting parameters to the equipment to be adjusted so that the equipment to be adjusted responds to the picture adjusting instruction, and performing picture adjusting processing according to the picture adjusting parameters.
In the embodiment of the present invention, when the microprocessor receives the intensity of the external light sent by the photosensitive sensor, the microprocessor may determine the picture adjustment parameter according to the intensity of the external light obtained by the photosensitive sensor, where the picture adjustment parameter may include a brightness adjustment parameter, a contrast adjustment parameter, and the like.
In one embodiment of the present invention, when the number of the photosensitive sensors is multiple, and the microprocessor receives the intensity of the external light sent by the photosensitive sensors, the intensity of the external light used for determining the picture adjustment parameter may be determined according to the intensity of the external light acquired by each photosensitive sensor, for example, the photosensitive sensors may determine the picture adjustment parameter according to an average value of the intensities of the external light acquired by each photosensitive sensor.
In the embodiment of the present invention, after determining the picture adjustment parameter, the microprocessor may send a picture adjustment instruction carrying the picture adjustment parameter to the device to be adjusted, for example, send a picture adjustment instruction carrying the picture adjustment parameter to an image processing chip of the device to be adjusted; when receiving the picture adjusting instruction, the device to be adjusted can respond to the picture adjusting instruction and perform picture adjusting processing, such as adjusting picture brightness, contrast and the like, according to picture adjusting parameters carried in the picture adjusting instruction.
Therefore, in the method flow shown in fig. 1, by deploying the picture adjusting device, the picture adjusting device can acquire the intensity of the external light through the photosensitive sensor, and send the acquired intensity of the external light to the microprocessor, the microprocessor determines the picture adjusting parameter according to the intensity of the external light acquired by the photosensitive sensor, and controls the device to be adjusted to perform picture adjustment according to the picture adjusting parameter, so that the picture of the device to be adjusted is automatically adjusted, the picture adjusting effect is optimized, and the picture adjusting efficiency is improved.
Further, in the embodiment of the present invention, when the photosensitive sensors are disposed in both the frame of the display screen and the display screen of the device to be adjusted (i.e., an implementation manner of the device to be adjusted in the above embodiment when the device to be adjusted is a projector), the microprocessor may determine, according to the detection condition of each photosensitive sensor on the intensity of the external light, an area where the external light is irradiated onto the display screen, and further, may control the device to be adjusted to perform local picture adjustment processing.
Correspondingly, in an embodiment of the present invention, the determining, by the microprocessor, an image adjustment parameter according to the external light intensity obtained by the photosensitive sensor, and sending an image adjustment instruction carrying the image adjustment parameter to the device to be adjusted by the microprocessor may include:
the microprocessor determines the position of a local area of the development screen, which is irradiated by the external light, according to the position of the target photosensitive sensor, in the development screen, where the acquired intensity of the external light meets the preset condition, and controls the to-be-adjusted device to perform picture adjustment processing on the local area of the development screen.
In this embodiment, when the photosensitive sensors are disposed in the frame of the display screen and the display screen of the device to be adjusted, and the microprocessor receives the intensity of the external light sent by each photosensitive sensor, before determining the picture adjustment parameter according to the intensity of the external light obtained by each photosensitive sensor, it is further required to first determine whether the intensity of the external light obtained by each photosensitive sensor meets a preset condition.
Optionally, in this embodiment, the intensity of the external light meeting the preset condition may include:
the intensity of the external light is greater than a preset threshold value; or the like, or, alternatively,
the intensity of the outside light is greater than the average value of the intensities of the outside light acquired by the photosensitive sensors.
In an optional implementation manner of this embodiment, a threshold used for determining whether the intensity of the external light meets a preset condition may be preset, where the threshold may be an empirical value or an experimental value, and may be set according to an actual application scenario, for example, the threshold may be a minimum intensity of the external light that affects a viewing effect of a user on a played image when the image is played by a projector in a conference room of a company, or when the image is played by a projector in a living room or a bedroom.
Accordingly, after the microprocessor receives the intensity of the external light transmitted by each of the light-sensitive sensors, the microprocessor may compare the intensity of the external light acquired by each of the light-sensitive sensors with the threshold, and determine that the intensity of the external light higher than the threshold satisfies a preset condition, and further, the microprocessor may determine a local area (hereinafter, referred to as a target area) of the display screen irradiated with the external light according to a position of the light-sensitive sensor (herein, referred to as a target light-sensitive sensor) in the display screen, where the acquired intensity of the external light satisfies the preset condition.
In another optional implementation manner of this embodiment, it is considered that a difference between the intensities of the external light detected by the photosensitive sensors in the area directly irradiated by the external light such as sunlight and the photosensitive sensors disposed in the area not directly irradiated by the external light on the display screen is relatively large, and therefore, after the microprocessor receives the intensities of the external light sent by the photosensitive sensors, the microprocessor may calculate an average value of the intensities of the external light acquired by the photosensitive sensors, determine the intensity of the external light higher than the average value as the intensity of the external light meeting the preset condition, and determine the target area irradiated by the external light on the display screen according to the position of the target photosensitive sensor in the display screen where the acquired intensity of the external light meets the preset condition.
It should be appreciated that the two specific implementations described above for determining whether the intensity of the external light meets the preset condition are only specific examples of determining whether the intensity of the external light meets the preset condition in the embodiments of the present invention, and are not limited to the scope of the present invention, i.e. in the embodiments of the present invention, the intensity of the external light meets the preset condition may also be determined in other ways, for example, the microprocessor may compare the intensities of the external light acquired by the photosensors, since the intensities of the external light acquired by the photosensors disposed in the area irradiated by the external light are relatively close, the intensities of the external light acquired by the photosensors disposed in the areas not irradiated by the external light are also relatively close, and the difference between the intensities of the external light between the two areas is relatively large, so that the intensities of the external light acquired by the photosensors on the whole display screen may be generally divided into two parts, the intensity of the external light in one of the portions is obviously greater than that of the external light in the other portion, and the microprocessor can determine that the portion with the greater intensity of the external light meets the preset condition.
In this embodiment, after the microprocessor determines the target photosensitive sensors whose acquired intensities of the external light satisfy the preset conditions, the target area of the development screen irradiated by the external light may be determined according to the positions of the target photosensitive sensors in the development screen.
In an optional implementation manner of this embodiment, the determining, by the microprocessor, a target area of the development screen irradiated by the ambient light according to the position of the target photosensitive sensor in the development screen may include:
when the target photosensitive sensors are included on 3 or 4 frames of the development screen, or when the target photosensitive sensors are included on 2 opposite frames of the development screen, or when the target photosensitive sensors are included on two adjacent frames of the development screen and the target photosensitive sensors are not included in the development screen, the microprocessor determines the target area according to the position of the target photosensitive sensors at the critical end on the frames of the development screen.
It should be noted that, when the target photosensor is included in N (N is an integer, and 0 < N < 4) frames of the development screen, it indicates that the target photosensor is not included in the other 4-N frames of the development screen, and the embodiment of the present invention will not be repeated in the following.
In this embodiment, considering that the light travels along a straight line, the area on the display screen irradiated with the external light should be a continuous surface, and the boundary of the area is a smooth straight line.
Accordingly, when the microprocessor determines that the target photosensor is included on 3 or 4 frames of the development screen, or the target photosensor is included on 2 opposite frames, or the target photosensor is included on 2 adjacent frames, and the target photosensor is not included in the development screen, the microprocessor may directly determine the target region according to the position of the target photosensor at the critical end on the frame of the development screen.
The target photosensitive sensor at the critical tail end on the frame is a target photosensitive sensor adjacent to one side of the frame, and the photosensitive sensor adjacent to the other side is not the target photosensitive sensor.
The above-mentioned several cases are respectively exemplified with reference to the accompanying drawings.
It should be noted that, in the embodiment of the present invention, it is assumed that a plurality of photosensitive sensors are uniformly and densely distributed on a frame of a display screen, and the photosensitive sensors disposed in the display screen are in a grid shape, and a schematic diagram thereof is shown in fig. 2; the positions of the photosensitive sensors on the frame and the photosensitive sensors in the screen are marked in a coordinate (x, y) mode, the coordinate of the photosensitive sensor at the leftmost lower corner of the frame of the development screen is (0, 0), the coordinate of the photosensitive sensor at the rightmost upper corner of the frame of the development screen is (1920, 1080), and the numerical value corresponds to the position of the pixel point one by one.
Referring to fig. 3A and 3B, which are schematic diagrams of a situation where 3 frames of the development screen include target photosensors, in the scenario shown in fig. 3A or 3B, the microprocessor first connects adjacent target photosensors on the frames of the development screen, i.e., determines 3 boundaries of a target area, and then the microprocessor can determine positions of the target photosensors at critical ends on the frames and connect the target photosensors at the critical ends of the frames with the target photosensors at nearby critical ends of the adjacent frames; if the adjacent frames do not have the target photosensitive sensors, the target photosensitive sensors at the near-end critical tail ends of the frames are found and connected with each other to determine a target area.
It should be noted that, in the embodiment of the present invention, the target photosensor at each critical end only has one target photosensor at another critical end to be connected.
Referring to fig. 3C, which is a schematic diagram of a situation in which 4 frames of the display screen include the target photosensors, in the scenario shown in fig. 3C, the microprocessor first connects the adjacent target photosensors on the frames of the display screen, i.e., determines 4 boundaries of the target area, and then the microprocessor can determine the positions of the target photosensors at the critical ends on the frames, and connect the target photosensors at the critical ends of the frames with the target photosensors at the nearby critical ends of the adjacent frames to determine the target area.
Referring to fig. 3D, which is a schematic diagram of another case where 4 frames of the display screen include the target photosensors, in the scene shown in fig. 3D, the microprocessor first connects the adjacent target photosensors on the frames of the display screen, and thus the target area can be determined.
Referring to fig. 3E and 3F, which are schematic diagrams of a situation in which 2 opposite borders of the development screen include the target photosensors, in a scene shown in fig. 3E or 3F, the microprocessor first connects the adjacent target photosensors on the borders of the development screen, i.e., determines 2 borders of the target area, and then the microprocessor can determine the positions of the target photosensors at the critical ends on the borders and connect the target photosensors at the critical ends of the borders with the target photosensors at the nearby critical ends of the adjacent borders; if the adjacent frames do not have the target photosensitive sensors, the target photosensitive sensors at the near-end critical tail ends of the frames are found and connected with each other to determine a target area.
Referring to fig. 3G, which is a schematic diagram of a situation where 2 adjacent frames of the development screen include the target photosensors and the development screen does not include the target photosensors, in the scenario illustrated in fig. 3G, the microprocessor first connects the adjacent target photosensors on the frames of the development screen, that is, 2 boundaries of the target area are determined, and then the microprocessor may determine the positions of the target photosensors at the critical ends on the respective frames and connect the target photosensors at the critical ends of the frames with the target photosensors at the nearby critical ends of the adjacent frames to determine the target area.
In another optional implementation manner of this embodiment, the determining, by the microprocessor, the target area of the development screen irradiated by the ambient light according to the position of the target photosensitive sensor in the development screen may include:
when the target photosensitive sensor is included on 2 adjacent frames of the development screen and the target photosensitive sensor is included in the development screen, or when the target photosensitive sensor is included on 1 frame of the development screen, the microprocessor determines the target area according to the position of the target photosensitive sensor at the critical end on the frame of the development screen and the position of the target photosensitive sensor farthest from the frame including the target photosensitive sensor in the horizontal direction or the vertical direction in the development screen.
In this embodiment, when the target photosensor is included on 2 adjacent frames of the development screen and the target photosensor is included in the development screen, or when the target photosensor is included on 1 frame of the development screen, the microprocessor may determine the target area according to the position of the target photosensor at the critical end on the frame of the development screen and the position of the target photosensor farthest from the frame including the target photosensor in the horizontal direction or the vertical direction in the development screen.
The above-mentioned several cases are also illustrated in the following description with reference to the drawings
Referring to fig. 4A, a schematic diagram of a situation in which 2 adjacent frames of the display screen include the target photosensors and the display screen includes the target photosensors is shown, in the scenario shown in fig. 4A, the microprocessor connects the adjacent target photosensors on the frames of the display screen first, that is, 2 boundaries of the target area are determined, and then the microprocessor may compare horizontal and vertical coordinates of the target photosensors in the display screen to determine the target photosensors located at the boundaries of the target area. In the scenario shown in fig. 4A, the microprocessor may determine the target photosensor with the maximum x value or the minimum y value as the target photosensor located at the boundary of the target area, and make a circle with a preset length (which may be set according to an actual scenario) as a radius with the target photosensor as a center, then make tangent lines of the circle from the positions of the target photosensors at the critical ends on the frame, respectively, and connect the tangent lines and the circular arcs, so as to approximately determine the target area, which may be shown in fig. 4B (the target area is an area surrounded by a dotted line in the figure).
Referring to fig. 4C, which is a schematic diagram illustrating a situation where 1 frame of the display screen includes the target photosensors, in the scenario illustrated in fig. 4C, the microprocessor first connects adjacent target photosensors on the frame of the display screen, that is, determines 1 boundary of the target area, and then the microprocessor may compare horizontal and vertical coordinates of each target photosensor in the display screen to determine the target photosensors located at the boundary of the target area. In the scenario shown in fig. 4C, the microprocessor may determine the target photosensor with the maximum x value as the target photosensor located at the boundary of the target area, and make a circle with a preset length (which may be set according to an actual scenario) as a radius with the target photosensor as a center, then make tangent lines of the circle from the position of the target photosensor at the critical end on the frame, make a common tangent line to the circle formed by the target photosensors inside the screen, and connect the tangent lines and the circular arcs to approximately determine the target area, which may be shown in fig. 4D (the target area is an area surrounded by a dotted line in the figure).
It should be noted that, in the embodiment of the present invention, when a circle is made with a selected target photosensor in the display screen as a center, the diameter of the circle needs to be smaller than the distance between two adjacent photosensors in the display screen.
It should be appreciated that the implementation manners of determining the target area described above are only some specific examples of determining the target area in the embodiment of the present invention, and are not limited to the scope of the present invention, that is, in the embodiment of the present invention, the target area may also be determined in other manners, for example, in the scene shown in fig. 4A or fig. 4C, after the target photosensor located at the boundary of the target area in the display screen is determined, the target photosensor located at the boundary of the target area and the target photosensor located at the critical end on the frame may be directly connected by a line to determine the target area, and specific implementations thereof are not described herein again.
Therefore, in the embodiment of the present invention, after the microprocessor receives the intensity of the external light acquired by the photosensitive sensors, the microprocessor may further determine the target area on the display screen irradiated by the external light according to the intensity of the external light acquired by each photosensitive sensor, and control the device to be adjusted to perform the targeted picture adjustment on the target area, so that the controllability and flexibility of the picture adjustment are improved.
Further, in the embodiment of the present invention, when the device to be adjusted performs picture adjustment on a local picture, in order to avoid a large color difference between the adjacent area of the area where picture adjustment is performed and the adjacent area where picture adjustment is not performed, a transition zone with a preset width (which may be set according to an actual scene, for example, 5cm) may be set at a position where the adjacent area of the area where picture adjustment is performed and the adjacent area where picture adjustment is not performed, that is, a transition zone with a preset width may be set at an adjacent position between the target area and another area except the target area in the display screen, so that the picture color of the device to be adjusted is uniformly transitioned.
As can be seen from the above description, in the technical solution provided in the embodiment of the present invention, by deploying the picture adjusting device, the picture adjusting device obtains the intensity of the external light through the frame of the display screen of the device to be adjusted and the photosensitive sensor inside the display screen, and sends the obtained intensity of the external light to the microprocessor of the picture adjusting device, the microprocessor determines the position of the local area of the display screen, which is irradiated by the external light, according to the intensity of the external light obtained by the photosensitive sensor, and controls the device to be adjusted to perform picture adjustment processing on the local area of the display screen, so that automatic adjustment of the picture of the local area of the device to be adjusted is realized, a picture adjusting effect is optimized, and picture adjusting efficiency is improved.
