Technical Field
The invention relates to the technical field of virtual display equipment, in particular to a control method of contrast of AR (augmented reality) glasses, a storage medium and the AR glasses.
Background
Currently, most AR (Augmented Reality ) glasses are the same as conventional glasses in terms of style, i.e., AR lenses for displaying images are placed in front of eyes of users, and image data is processed through a main chip of AR and converted into image information that can be perceived by users. Wherein the contrast is typically expressed as the ratio of the brightness of the brightest area to the brightness of the darkest area in an image. Thus, the higher the white luminance value in the image, the lower the black luminance value, and the higher the contrast. The vivid and rich colors can be better displayed when the contrast ratio is high, and dark color contents cannot be correctly displayed when the contrast ratio is low.
In the prior art, contrast ratio can be improved by improving brightness of an image displayed by the AR glasses, but the mode requires improving brightness of a projection optical machine, the improvement of the brightness of the optical machine can cause power consumption increase of the AR glasses, and meanwhile, the power consumption is converted into heat, so that a great challenge is brought to heat dissipation. Contrast can also be improved by reducing the amount of ambient light transmitted, for example by placing a dark shade on the front side of the AR glasses, which reduces the impact of ambient light on the AR low-brightness image, but also reduces the supplemental effect of ambient light on the high-brightness areas, and is therefore not optimal.

Also included is a first electrode layer 32 for placing the individual electrodes of the first side partition, which refers to the left side partition, and a second electrode layer 34 for placing the individual electrodes of the second side partition, which refers to the right side partition.

According to this arrangement, a controllable dimming module 30 is obtained.
In one possible implementation, the AR glasses further include a first main control chip, configured to generate an image to be displayed, divide the image to be displayed into a plurality of virtual partitions according to a partition rule preset by the controllable dimming module 30, calculate luminance information of each virtual partition in the image, for example, calculate an average luminance value of each virtual partition in the image, and send the average luminance value of each partition to the controllable dimming module 30 synchronously.

The embodiment of the application further provides a method for controlling the contrast of the AR glasses, and fig. 1 is a schematic flow chart of a method for controlling the contrast of the AR glasses according to an exemplary embodiment, as shown in fig. 1, and the method includes the following steps.
S101, dividing an image to be displayed into a plurality of virtual partitions according to partition rules preset by the controllable dimming module.
In one possible implementation manner, the light transmittance regulation layer in the controllable light modulation module is partitioned first, and when the diaphragm is developed, the partition is performed according to the physical material, partition requirement and other conditions of the diaphragm, and the specific partition rule is not limited in particular. Fig. 5 is a schematic diagram illustrating membrane partitions of a controllable dimming module according to an exemplary embodiment, as shown in fig. 5, the membrane may be divided into cd rows and ab columns, and the membrane may be divided into 144 partitions, taking cd equal to 09 and ab equal to 16 as an example.
Further, a first main control chip in the AR glasses generates an image to be displayed, and then the image to be displayed is also divided into virtual partitions corresponding to the positions of the diaphragm subareas according to the partition rules of the diaphragms. In one possible implementation, the image area of the AR glasses is correspondingly also divided into 144 virtual partitions. For example, when AR glasses display images of 1920×1080 resolution, the size of each image virtual sub-partition is 120×120 (1920/16=120, 1080/9=120) pixels.
S102, calculating the brightness information of each virtual partition in the image, and sending the brightness information to the controllable dimming module.
After virtual partitioning is carried out on the image, the first main control chip of the AR glasses calculates the brightness information of each virtual partition in the image, and then the calculated brightness information of each partition is sent to the second main control chip in the controllable dimming module. In one possible implementation, an average brightness value of each virtual partition in the image is calculated, and the average brightness value of each partition is sent to a second main control chip in the controllable dimming module.
S103, controlling the controllable dimming module to adjust the light transmittance of the corresponding partition according to the brightness information.
In one possible implementation, the controllable dimming module is disposed outside the lens of the AR glasses, and the transmittance of the membrane can be adjusted in a partitioned manner, so as to improve the contrast ratio of the image entering the human eye.
Specifically, the controllable dimming module comprises a light transmittance regulating layer, wherein the size of the light transmittance regulating layer covers the image display area of the whole lens and is divided into a plurality of subareas. Each zone has an independent control electrode. The device also comprises an independent electrode layer for placing the electrode and a second main control chip connected with the electrode outgoing line.
Further, a second main control chip in the controllable dimming module is connected with a first main control chip in the AR glasses and is used for receiving the average brightness value of each partition and converting the average brightness value of each partition into control voltage, and the first main control chip controls a control circuit in each virtual partition to adjust light transmittance according to the received control voltage.
Because of the physical properties of the membrane and the design of the control circuit, when the brightness value is high, the corresponding control voltage may be large or small, and the embodiments of the disclosure are not particularly limited. However, a specific control strategy includes increasing the light transmittance of the corresponding partition in the membrane by the converted control voltage when the brightness value of the image partition is relatively high, and decreasing the light transmittance of the corresponding partition in the membrane by the converted control voltage when the brightness value of the image partition is relatively low. By the design, the bright area and the dark area in the image entering the eyes can be brighter, so that the brightness of each subarea can be finely compensated, and finally the contrast ratio of the whole image is improved.
In order to facilitate understanding of the control method of the contrast ratio of the AR glasses provided in the embodiments of the present application, the following description is made with reference to fig. 2. As shown in fig. 2, the method includes the following steps.
Firstly, an AP (Application Processor, application chip) chip in the AR glasses, namely a first main control chip, generates an image to be displayed, then sends the image to be displayed to an optical machine, the optical machine preprocesses the image and generates a processed display image, and the display image sent by the optical machine is subjected to a series of refraction of a lens and finally displayed in the lens.
After the first main control chip generates an image to be displayed, virtual partitioning is carried out on the image to be displayed according to partitioning rules of the controllable light modulation module, the average brightness value of each virtual partition in the image is calculated, the average brightness value of each virtual partition in the image is sent to the second main control chip in the controllable light modulation module, the second main control chip in the controllable light modulation module converts the average brightness value of each partition into control voltage, and the first main control chip controls a control circuit in each virtual partition to adjust light transmittance according to the received control voltage. Wherein, the controllable module of adjusting luminance sets up in the outside of AR lens.
According to the AR glasses, the AR lenses can display images, and the diaphragm can adjust the light transmittance in a partitioning mode, so that the contrast ratio of the images displayed by the AR glasses can be effectively guaranteed in different environment scenes, the detail information of the images can be obtained by a user, and the user experience is improved.
According to the control method for the contrast ratio of the AR glasses, the diaphragm capable of adjusting the light transmittance in a partitioning mode is arranged on the outer side of the lens and used for adjusting the light transmittance of each sub-area of the diaphragm. When the average brightness of the virtual image subarea to be displayed is higher, the light transmittance of the diaphragm area corresponding to the virtual image is improved, so that more external ambient light enters eyes through the AR lens, and the brightness of the actual image of the area is enhanced. When the average brightness of the virtual image subareas is lower, the light transmittance of the diaphragm of the corresponding image area is reduced, and the external ambient light is reduced to enter eyes, so that the low-brightness information in the actual image is well reserved. By the method, the bright area in the image entering the eyes can be brighter, and the dark area is darker, so that the contrast of the whole image is improved. In different environments, the detail information of the image can be ensured to be acquired by the user, and the user experience is improved.
