Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a picture adjustment method of a display device according to the present invention, in which the picture adjustment method of the display device includes the steps of:
step S10: acquiring distance information between eyes of a display device wearer and lenses on a lens barrel of the display device;
in this embodiment, the display device may include a head-mounted display device, such as a head-mounted display device based on VR (Virtual Reality), AR (Augmented Reality) technology or holographic technology, or other display devices that need to adjust the screen display parameters according to the distance information. The display device is provided with a human body proximity sensor which is used for acquiring the relative position information of the human body of the wearer of the display device and the head-mounted display device, and determining the distance between the eyes (particularly eyeballs) of the wearer of the display device and the lenses on the lens cone of the display device according to the relative position information, so as to acquire the distance information between the eyes of the wearer of the display device and the lenses on the lens cone of the display device. Based on the face difference, the proximity sensor may be one, for example, the proximity sensor may be disposed on the display device at a position opposite to a middle position of two eyes, so as to obtain distance information between eyes of a wearer of the display device and lenses on a lens barrel of the display device; or two of the display device can be arranged to respectively acquire the distances between the eyes of different wearers and the display device, so that the situation that one eye of part of the wearers has visual disorder is prevented, and the distance information between the eyes of the wearers of the display device and the lenses on the lens barrel of the display device is acquired more accurately. On the basis, the number and the positions of the proximity sensors can be set or started according to specific application conditions, so that display adjustment parameters of a display device picture can be more accurately determined according to the acquired distance information, and the display parameters of the display device can be adjusted according to the display adjustment parameters, so that the adjusted display picture is matched with a display area in the visual range of a wearer.
Step S20: determining display adjustment parameters of a display device picture according to the distance information;
when the distance between the eyes of the wearer and the lenses on the lens cone is different, the corresponding display areas in the visual range of the wearer are also different, and when the display areas in the visual range are changed, the display adjustment parameters of the display device picture corresponding to the current wearing distance are required to be determined according to the distance information of the eyes of the wearer and the lenses on the lens cone, and then the display parameters of the display device are adjusted according to the display adjustment parameters, so that the display picture of the display device is matched with the visual range corresponding to the different distances. The display adjustment parameters particularly refer to adjustment parameters that the display picture needs to be adjusted when the display picture of the display device needs to be adjusted, and if the size of the display picture needs to be adjusted, corresponding adjustment proportions need to be determined, so that the display adjustment parameters at least comprise picture scaling parameters, corresponding adjustment types and adjustment values can be determined according to the picture scaling parameters, and if the adjustment types can be amplification adjustment or reduction adjustment, the adjustment values can be amplification or reduction adjustment correspondingly; the display parameters of the display device refer to parameters corresponding to display pictures to be output, such as a display area of the display pictures to be output, resolution corresponding to the output of the display pictures in the display area, and the like, and after the display parameters of the display device are adjusted, the system carries out corresponding processing on the display pictures to be output according to the adjusted display parameters, so that the processed display pictures can be matched with the adjusted display parameters. Therefore, before the display parameters of the display device are adjusted according to the display adjustment parameters, in order to determine the display adjustment parameters of the display device picture, a reference display area in a visual range and a reference distance corresponding to the reference display area in the visual range may be determined first, and then the display adjustment parameters of the display device picture may be determined according to the relationship (such as a size relationship or a ratio relationship) between the distance information of the eyes of the wearer and the lenses on the lens barrel and the reference distance; of course, the display adjustment parameters of the display device picture may be determined according to the relationship (such as a size relationship or a ratio relationship) between the display area in the determined visual range and the reference display area in the visual range. The reference display area in the visual range may be a display area when the image is the clearest in the visual range of the wearer, or may be a maximum display area which can be observed on a display screen of the display device in the visual range of the wearer, and the reference display area may be specifically set according to the actual situation.
Step S30: adjusting the display parameters of the display equipment according to the display adjustment parameters so as to enable the adjusted display picture to be matched with a display area in the visual range of a wearer;
after the display adjustment parameters are determined, the display parameters of the display equipment are adjusted according to the display adjustment parameters, so that the adjusted display picture is matched with the display area in the visual range of the wearer. And to adjust the display parameters of the display device according to the display adjustment parameters, the adjustment type and the corresponding adjustment value can be determined according to the display adjustment parameters, and then the display parameters of the display device are adjusted according to the adjustment type and the corresponding adjustment value, so that the adjusted display picture is matched with the display area in the visual range of the wearer. Specifically, if the display equipment is required to be subjected to amplification adjustment according to the display adjustment parameter adjustment, corresponding amplification factors are determined according to the display adjustment parameter adjustment, the display size of the amplified display equipment picture can be determined according to the amplification factors and the reference display area in the visual range, and the display parameter of the display equipment is adjusted according to the determined display size, so that the adjusted display picture is matched with the display area in the visual range of a wearer, and the complete display picture is ensured to be presented to the wearer in the visual range of the wearer; if the display equipment is required to be reduced and adjusted according to the display adjustment parameter adjustment, corresponding reduction factors are determined according to the display adjustment parameter, the display size of the reduced display equipment picture is determined according to the reduction factors and the reference display area in the visual range, and the display parameter of the display equipment is adjusted according to the determined display size, so that the adjusted display picture is matched with the display area in the visual range of a wearer. The display area within the visual range of the wearer refers to a display area on a display screen that is viewable by the wearer through a barrel lens of the display device at a current wearing distance.
According to the embodiment, the distance information of the eyes of the wearer of the display device and the lenses on the lens barrel of the display device is obtained, the display adjustment parameters of the picture of the display device are determined according to the distance information, and then the display parameters of the display device are adjusted according to the display adjustment parameters, so that the adjusted display picture is matched with the display area in the visual range of the wearer, the user can have the same picture experience sense under different wearing distances, different display areas in the visual range of different wearers due to wearing problems or individual difference problems are avoided, clear and complete display pictures are output to the user, and therefore reliability of picture output and picture display effect are improved.
Referring to fig. 3, fig. 3 is a flowchart of a second embodiment of a picture adjustment method of a display device according to the present invention, in which the picture adjustment method of the display device includes the steps of:
step S11: acquiring distance information between eyes of a display device wearer and lenses on a lens barrel of the display device;
step S12: determining a display area in the visual range of the wearer according to the distance information;
step S13: determining display adjustment parameters of the display equipment picture according to the display area in the visual range of the wearer and a preset threshold display area;
Step S14: and adjusting the display parameters of the display equipment according to the display adjustment parameters so as to enable the adjusted display picture to be matched with the display area in the visual range of the wearer.
In this embodiment, after distance information between an eye of a wearer of the display device and a lens on a lens barrel of the display device is obtained, a display area within a visual range of the wearer of the display device is first determined according to the distance information, then a display adjustment parameter of a picture of the display device is determined according to the display area within the visual range of the wearer and a preset threshold display area, and the display parameter of the display device is adjusted according to the display adjustment parameter, so that the adjusted display picture is matched with the display area within the visual range of the wearer. In order to adapt to the visual requirements of different wearers as far as possible, a threshold display area is usually determined according to the characteristics of different human bodies, and before the display area in the visual range of the wearer is determined according to the acquired distance information, the threshold display area is generally used as a default display area of the system, that is, the display device defaults to display pictures in the threshold display area, that is, the pictures of the display device defaults to display pictures with the resolution matched with the threshold display area. Thus, in this embodiment, the preset threshold display area is especially the maximum display area visible in the visual range of different wearers of the display device default setting when wearing the display device. Therefore, according to the relation between the display area in the visual range of the wearer and the preset threshold display area, the display adjustment parameter of the display device picture can be determined, the picture display size of the display device can be determined according to the display adjustment parameter, and the display parameter of the display device is adjusted according to the determined picture display size, so that the adjusted display picture is matched with the display area in the visual range of the wearer so as to adapt to the visual requirements of different wearers or the visual requirements of the same wearer at different distances, and the detected distance information is different when the wearing postures of the same wearer are different.
In a specific embodiment, the display adjustment parameter of the display device screen may be determined according to a relationship between the display area in the visual range of the wearer and the area of the preset threshold display area. Specifically, the area of the display area in the visual range can be compared with the area of the preset threshold display area to obtain an area ratio, a display adjustment parameter of the display equipment picture is determined according to the area ratio, whether the adjustment type is amplification adjustment or reduction adjustment is determined according to the display adjustment parameter, corresponding amplification factor or reduction factor is determined, and then the display parameter is adjusted according to the corresponding amplification factor or reduction factor of the adjustment type, so that the adjusted display picture is matched with the display area in the visual range of a wearer. Before comparing the area of the display area in the visual range with the area of the display area with a preset threshold value, the area of the display area of the wearer in the visual range needs to be determined. In an embodiment, the display area in the visual range of the wearer can be determined according to the distance information between the eyes of the wearer and the lenses on the lens barrel of the display device, the distance information between the lens barrel and the display screen and the radius of the lens barrel. Specifically, the distance information between the eyes of the wearer and the lenses on the lens barrel and the distance information between the lens barrel and the display screen of the display device can be determined firstly (the distance between the eyes of the wearer and the display screen is the sum of the distance between the eyes of the wearer and the lenses on the lens barrel and the distance between the lenses on the lens barrel and the display screen of the display device), then the distance ratio between the eyes of the wearer and the distances between the eyes of the wearer and the lenses on the lens barrel is determined according to the distance information between the eyes of the wearer and the display screen and the distance information between the eyes of the wearer and the lenses on the lens barrel, then the product of the distance ratio and the radius of the lenses on the lens barrel is used as the radius of the display area in the visual range, and then the area of the display area in the visual range is calculated by using the area formula of a circle according to the radius of the display area in the visual range.
Specifically, as shown in the schematic diagram of the calculation of the display area in the visual range of the wearer shown in fig. 4, it can be seen from the figure that the distance between the eyes of the wearer and the lens on the lens barrel is X, the distance between the lens on the lens barrel and the display screen is X' (fixed value), and the lens area of the lens barrel is S (fixed value). The radius of the lens on the barrel is r (fixed value), and the display area S 'in the visual range of the wearer (in this case, the radius of the display area in the visual range is r'). As is clear from the change in the eye position of the wearer in the figure, if the wearer' S eyes are far from the lenses on the lens barrel, the display area in the visual range of the wearer is S "(in this case, the radius of the display area in the visual range is r"), and obviously, r″ "<At r', S<S', namely, the farther the distance between the eyes of the wearer and the lenses on the lens barrel is, the smaller the viewable display area in the visual range of the wearer is, otherwise, the closer the distance between the eyes of the wearer and the lenses on the lens barrel is, the larger the viewable display area in the visual range of the wearer is. If the included angle between the straight line where the circle center of the display area in the visual range and the wearer's eyes is located and the straight line where any point on the circumference of the display area in the visual range is located is alpha, the method can obtain the eye mask according to the right triangle theorem And->So that the equal amount relation between the two can be obtained>Thereby, the radius r' of the display area in the visual range of the wearer is +.>Since the display area viewable by the wearer of the round lens through the barrel is a round area, according toThe area formula of the circle can be obtained, and the area of the display area in the visual range of the wearer is +.>
In another embodiment, in order to avoid erroneous adjustment and improve adjustment efficiency, before determining the display adjustment parameters of the display device screen according to the display area and the preset threshold display area in the visual range of the wearer, whether the display area in the visual range of the wearer is consistent with the preset threshold display area or not is determined, if not, it is determined that the display parameters of the display device need to be adjusted, at this time, the display adjustment parameters of the display device screen may be determined according to the display area and the preset threshold display area in the visual range of the wearer, and then the display parameters of the display device may be adjusted according to the display adjustment parameters, for example, when the display area in the visual range of the wearer exceeds the preset threshold display area, an amplifying adjustment is required to be performed on the display screen of the display device, at this time, a corresponding amplifying factor is determined according to the display area and the preset threshold display area in the visual range of the wearer, and the display parameters of the display device are adjusted according to the amplifying factor; when the display area in the visual range of the wearer is smaller than the preset threshold display area, the display picture of the display equipment is required to be reduced and adjusted, corresponding reduction factors are determined according to the display area in the visual range of the wearer and the preset threshold display area, and display parameters of the display equipment are adjusted according to the reduction factors. On the other hand, if the display area in the visual range of the wearer is consistent with the preset threshold display area, it is determined that the adjustment of the display parameters of the display device is not required, and at this time, the display parameters corresponding to the preset threshold display area are directly used for displaying the picture.
In a further embodiment, after determining the display adjustment parameters of the display device screen according to the area ratio of the display area in the wearer's visual range to the preset threshold display area, the display of the display device is adjusted according to the display adjustment parametersThe step of parameters to match the adjusted display to the display area within the visual range of the wearer includes: adjusting the display parameters of the display equipment according to the display adjustment parameters to obtain adjusted display parameters; and scaling the resolution of the display picture according to the area ratio according to the adjusted display parameter so as to enable the processed display picture to be matched with the display area in the visual range of the wearer.

Specifically, since the distance between the eyes of the wearer and the lenses on the lens barrel is in inverse relation with the visible display area of the wearer in the visual range, if the distance between the eyes of the wearer and the lenses on the lens barrel is smaller than a first distance threshold, it is determined that the display picture of the display device needs to be subjected to amplification adjustment, and at the moment, the amplification adjustment parameters of the display device picture need to be determined according to the distance information, so that the display parameters of the display device are adjusted according to the amplification adjustment parameters; if the distance between the eyes of the wearer and the lenses on the lens cone is larger than a second distance threshold, determining that the display picture of the display equipment needs to be reduced and adjusted, and determining the reduction and adjustment parameters of the display picture of the display equipment according to the distance information, so that the display parameters of the display equipment are adjusted according to the reduction and adjustment parameters. The first distance threshold is particularly a preset distance threshold greater than a certain range of the reference distance, the second distance threshold is particularly a preset distance threshold less than the certain range of the reference distance, and the first distance threshold is less than or equal to the second distance threshold.
According to the embodiment, the distance information of the eyes of the wearer of the display device and the lenses on the lens barrel of the display device is obtained, so that whether the display parameters of the display device need to be adjusted or not is judged according to the distance information, when the display parameters of the display device need to be adjusted, the display adjustment parameters of the pictures of the display device are determined according to the distance information, then the display parameters of the display device are adjusted according to the display adjustment parameters, so that the adjusted display pictures are matched with the display area in the visual range of the wearer, whether the display parameters of the display device need to be adjusted or not is directly judged according to the distance information, and corresponding parameter adjustment is directly carried out according to the distance information when the adjustment is needed, so that the picture display effect is improved, the reliability of picture output is improved, the processing efficiency of the adjustment of the display parameters is improved, and the processing process is simplified.
