Description
Technical Field
The embodiment of the invention relates to the technical field of 3D display, in particular to a method, a device, equipment and a storage medium for determining a crosstalk value of a display device.
Background
When a user views an object, the user can perceive the shape of the object, can perceive the object to be far away from the user and the relative position relationship between the object and the user, and a display capable of displaying the complete object space information is called a 3D display. With the development of scientific technology, 3D display technology has been developed.
The naked-eye 3D display means that an observer can directly view a 3D image without wearing special 3D glasses, that is, a 3D effect is presented. The principle of the technology is that a layer of cylindrical lenses is prepared on a conventional display screen, specifically, pixels of an image below each cylindrical lens are divided into a plurality of sub-pixels, and the lenses can project each sub-pixel in different directions. When a user watches 3D display content, the left eye and the right eye respectively see light rays emitted by different sub-pixels, so that the left eye and the right eye see different pictures and are fused into a display picture with a 3D effect in the brain.
Each pixel point can be projected to the left eye and the right eye separately through the cylindrical lens, and therefore the phenomenon of crosstalk when a user watches images is possibly caused. The size of crosstalk is an important index for measuring the performance of a naked eye 3D display device, the traditional method for measuring the crosstalk mainly comprises space light intensity distribution measurement and plane light intensity distribution measurement, and the two measurement methods can accurately measure the crosstalk degree of the 3D display device. However, the above-mentioned measurement method needs to use a specific measurement device, and the time consumed in the space or plane scanning in the measurement process is relatively long, and the crosstalk degree of the 3D display device that can be obtained only by accurately calculating is also required, which results in a relatively complicated implementation process.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flowchart of a method for determining a crosstalk value of a display device according to an embodiment of the present invention, where the method can be executed by a device for determining a crosstalk value of a display device, and the device can be implemented in a form of software and/or hardware.
As illustrated in fig. 1, the method of the embodiment of the present invention includes:
and S110, acquiring a crosstalk test image displayed by the stereo display device.
A stereoscopic display device may be understood as a device provided with a 3D display. It should be noted that most of the existing display devices are 2D display devices, and in order to achieve a 3D display effect, one of a lenticular lens, a slit grating, or a liquid crystal lens may be laid on a display screen of the 2D display device, so that the 2D display can be converted into a 3D display. The stereoscopic display device can be a mobile phone, a tablet, a notebook computer and other equipment with a display function. Of course, the image displayed on the display screen of the 3D display device has a certain crosstalk, which can be understood as an influence between different pixels covered by the raster. Therefore, before the stereoscopic display device is used, a crosstalk test needs to be performed on the device, that is, a crosstalk value of the stereoscopic display device is obtained, and the stereoscopic display device is adjusted according to the crosstalk value, so that the crosstalk of the display device is reduced. The crosstalk test image may be understood as an image to be displayed by the display device, that is to say a test image. Since the test image is an image with a certain gray scale, the image that the user can see is a two-dimensional image with a certain gray scale, and it should be noted that the two-dimensional image is defined only by the test image being a gray scale image.
S120, if the test brightness of the crosstalk test image is determined to be inconsistent with the standard brightness of the image at the target test position, adjusting the brightness of the crosstalk test image by changing the gray-scale value of the crosstalk test image.
The target position may be understood as a position where the target user observes whether the crosstalk test image brightness is consistent with the image standard brightness. It should be noted that the crosstalk between the images is not completely uniformly distributed on the display screen of the display device, that is, the crosstalk values obtained when the user observes the images in different areas at different positions are different, so that finding the optimal observation position can overcome the problem of non-uniform crosstalk distribution to the greatest extent. That is, before adjusting the test brightness of the crosstalk test image to be consistent with the standard brightness of the image, the target position where the target user is located when adjusting the brightness of the test image may be determined.
The determination of the target position may be determined according to imaging parameters of the stereoscopic display device, and specifically may be: determining a red-blue interweaved graph corresponding to imaging parameters according to the imaging parameters of the stereoscopic display device; determining the target position of a target user when the brightness image is adjusted according to the red-blue interleaving image; wherein the imaging parameters include parameters of a view separation element in the display device.
A display device generally used in the prior art is a 2D display device, and a requirement for realizing naked-eye 3D display satisfies that a current display device can display a 3D view. That is, one of a lenticular lens, a slit grating or a liquid crystal lens needs to be laid over the display screen of the 2D display device, so as to convert the 2D view into the 3D view. Optionally, a lenticular lens is laid on the display screen of the 2D display device to obtain the 3D display device. The imaging parameters of the stereoscopic display device are adjusted before the 3D display device is used, i.e. before the target position of the target user is determined. The imaging parameters include parameters of a view separation element in the display device. The view separation element can be understood as different gratings laid on the display screen, and different gratings correspond to different imaging parameters. For example, the grating laid on the display screen is a lenticular grating, and then the imaging parameters can be understood as parameter information such as the inclination angle of the lenticular grating and the number of covered pixels of each lenticular grating.
After the imaging parameters of the display device are adjusted, acquiring a pre-stored red-blue interleaved image, determining the target position of a target user according to the red-blue interleaved image, specifically, the target user moves an observation position, and when one eye of the target user observes that the red-blue interleaved image is red and the other eye observes that the red-blue interleaved image is blue in the process of moving the observation position, determining the current position of the target user as the target position; in the moving process, when the target user observes that the red-blue interleaved image is red for one eye and blue for the other eye, the display device is placed at the current position, and the current position of the target user is determined as the target position. The target user may adjust the brightness of the test image to be consistent with the standard image brightness at the current location.
Referring to fig. 2 and fig. 3, fig. 2 is a schematic diagram illustrating brightness adjustment of a test image according to brightness of a standard image, that is, an upper half of fig. 2 is a brightness map corresponding to the standard image under an ideal condition, and a lower half is the test image with a certain gray scale value. Referring to fig. 2, the brightness of the test image is adjusted to make the brightness of the test image consistent with the standard brightness of the standard image, and then the crosstalk value of the stereoscopic display device is determined according to the brightness adjustment result. The standard image may be understood as a view that a user can see under ideal conditions, and optionally, the left eye sees a pure white image and the right eye sees a pure black image. The standard image is understood to be an image that the user has preset to see. The standard brightness of the standard image can be understood as the standard brightness of the stereoscopic display device under ideal conditions, that is, the brightness of the image that can be seen by the user after passing through the 3D display device under ideal conditions, and optionally, the left eye of the user sees a pure white image, and the right eye of the user sees a pure black image, and then the brightness of the image that can be seen by the user after passing through the 3D display device. The standard brightness of the standard image may also be preset brightness as the standard brightness, which is to be understood that a user sets an image brightness in advance and uses the image brightness as a standard for adjusting the brightness of the test image, that is, the brightness of the test image is adjusted according to the preset image brightness. Theoretically, after being displayed by a stereoscopic display device, one eye of the user sees an all black image and the other eye sees an all white image, see fig. 3. However, in practice, the display device has a certain crosstalk, that is, the black image will have a certain crosstalk to white, and the white image will have a certain crosstalk to black, so that the image obtained in practice is a gray scale image with a certain gray scale as shown in fig. 3. When the user sees a view with a certain gray scale as shown in fig. 3, the key triggering the application program gets the test image brightness corresponding to said fig. 3, that is, gets the test image brightness with a certain gray scale value as shown in fig. 2. And adjusting the test brightness of the test image according to the standard brightness of the standard image.
S130, when the test brightness is determined to be consistent with the standard brightness at the target position, determining a crosstalk value of the stereoscopic display device according to a brightness adjusting result.
The target user can adjust the brightness of the test image at the target position by triggering a certain key, adjusting the brightness of the test image by adding or subtracting the key, or directly triggering the test brightness image displayed by the display screen to adjust the display brightness. Triggering the test image on the display screen, that is, the image shown in the lower half of fig. 2, and adjusting the brightness of the test image displayed by the display device by sliding upward or downward, it should be noted that a specific adjustment mode for adjusting the brightness of the test image may be set by a user according to actual needs, and is not limited herein.
Illustratively, the user's finger slides up, the brightness of the test image becomes bright; the user's finger slides down the test image, dimming in brightness. And in the process of adjusting the brightness of the test image, when the test brightness is determined to be consistent with the standard brightness at the target position, determining the crosstalk value of the display device according to the current brightness adjusting result. It should be noted that, adjusting the brightness of the test image according to the technical solution of the embodiment of the present invention may be understood as adjusting the gray scale of the test image.
The determining of the crosstalk value of the display device according to the current brightness adjustment result may specifically be: and acquiring a gray-scale value corresponding to the current brightness of the crosstalk test image, and determining the crosstalk value of the stereo display device according to the gray-scale value.
The crosstalk values of the display device may be displayed at any location known or set by the user, optionally on a display screen, above the test image, and/or at a location designated by the user. For example, the user may read the value at the designated position to obtain the crosstalk value corresponding to the display device.
Degree of crosstalk of display deviceThe value may be determined by the gray level value corresponding to the current luminance. The gray scale value can be understood as performing binarization processing on the image, and when the image is completely black, the corresponding gray scale value is 0; when the image is full white, the corresponding gray scale value is 255, and the gray scale of the image varies in the range of 0 to 255. Determining the crosstalk value of the display device according to the current brightness of the test image may be calculating a ratio of the gray-scale value to 255, and taking a power of 2.2 of the ratio as the crosstalk value of the stereoscopic display device. That is to say, in the process of adjusting the brightness of the test image, the gray-scale value corresponding to the current brightness can be obtained, and the ratio between the current gray-scale value and the maximum gray-scale value is calculated, wherein the power of 2.2 of the ratio is the crosstalk value of the display device. Illustratively, the gray level value corresponding to the luminance of the test image is G when the luminance of the test image is consistent with the luminance of the standard imagelThe maximum value of the gray scale value is 255, and an intermediate value is obtained by calculation and is marked as C-GlAnd 255, calculating the value obtained by the power of 2.2 of C to be the crosstalk value of the display device, displaying the crosstalk value at a preset position on a display screen, and directly reading the value by a user to obtain the crosstalk value of the display device.
The technical scheme of the embodiment of the invention comprises the steps of obtaining a crosstalk test image displayed by a three-dimensional display device, if the test brightness of the crosstalk test image is determined to be inconsistent with the standard brightness of the image at a target test position, adjusting the brightness of the crosstalk test image by changing the gray scale value of the crosstalk test image, and determining the crosstalk value of the three-dimensional display device according to the brightness adjustment result when the test brightness is determined to be consistent with the standard brightness at the target position, thereby solving the technical problems that the crosstalk value of the display device is obtained by adopting specific measuring equipment in the prior art, the time consumed in the process of obtaining the crosstalk value of the display device in the space or plane scanning image is long and the crosstalk value of the 3D display device can be obtained by accurately calculating, the process is complex, the measuring time is long and the convenience is poor, the crosstalk value of the current display device can be rapidly measured without special measuring equipment, and the technical effects of improving the efficiency of measuring the crosstalk value of the display device, saving the cost and saving the time are achieved.
