In order to increase the social contact function of the display device, the social television is exemplarily shown, and the social television adopts a camera-mounted mode so as to expand the use of the social television. Generally, the camera is hidden in the social television backboard and has an automatic lifting function. When the camera 1 is used, the camera 1 is raised, as shown in fig. 7; when the camera 1 is not used, the camera 1 is automatically lowered.

In order to protect the privacy of a user and prevent a camera from being lifted under the condition of misoperation and shoot the surrounding environment of the social television, an independent physical switch 2 which is not controlled by a main control panel of the social television is installed on the social television, as shown in fig. 8, the camera can be locked by the physical switch 2, and the camera 1 cannot be lifted after being locked. The physical switch 2 can avoid the camera shooting the surrounding environment of the social television under the condition that the user does not voluntarily due to misoperation. The physical switch with the privacy prevention function is arranged on the social television, so that the camera cannot shoot the surrounding environment under misoperation. However, the social television cannot know the physical switch state, including the locked state or the opened state, and at this time, when the physical switch is in the locked state, the camera cannot shoot a normal image.

In order to solve technical problems in the prior art, a first aspect of an embodiment of the present application shows a display device, where the display device includes:

a camera configured to: image data is collected, and the lifting or the lowering is controlled by a lifting power device. The camera may be the image collector 241 in fig. 2.

A physical switch configured to: the camera is locked at the lifting position, when the physical switch is in a locking state, the camera cannot be lifted by the lifting power device, when the physical switch is in an opening state, the camera can be lifted by the lifting power device, and therefore the camera can acquire normal image data.

A display configured to: a user interface, and/or the display image data;

a controller configured to: controlling the camera to ascend through a lifting power device in response to a command which is input by a user and used for indicating that the camera is opened;

detecting whether the camera is lifted within a preset time, and if the camera is not lifted, controlling the display to display a prompt message that the physical switch is in a locked state, for example, the prompt message that the physical switch is in the locked state is shown in fig. 9.

A display configured to: and displaying a prompt message that the physical switch is in the locking state.

In the embodiment of the application, when a user inputs a camera opening instruction, if the camera is not lifted, at this time, the user needs to be reminded how to normally lift the camera, as shown in fig. 9, a prompt message that the physical switch in fig. 9 is in a locked state includes a reminding character and a reminding operation diagram, specifically, the reminding character is that the camera may be locked or shielded, and it is recommended to unlock according to the diagram. The reminding operation schematic diagram is an operation method image of how to open the physical switch. In this way, the user may be prompted to open the physical switch.

In some embodiments, the controller is configured to perform the detecting whether the camera is lifted within the preset time according to the following steps, as shown in fig. 10, including: s100, acquiring a frame image of preset time in a preview image acquired by a camera;

in the embodiment of the application, the display equipment adopts the android system, the android system provides a callback interface for the camera, and the preview image shot by the camera can be returned.

It should be noted that, if the physical switch is in an on state, it takes a certain time for the camera to completely lift from the back plate of the display device, and a part of the camera may be blocked by a frame of the display device during the lifting process, as shown in fig. 11, the camera in fig. 11 is partially blocked, and a dotted line is a position after the camera is completely lifted, so that an image shot by the camera may have a normal image shot at an upper part, and an abnormal image shot at a lower part due to the blocking of the frame, as shown in fig. 12. With the continuous rising of the camera, normal images appear on the images shot by the camera from top to bottom, and when the camera is completely raised, all the images shot by the camera are normal images, wherein the normal images are real images of the surrounding environment of the display equipment. If the physical switch is in a locked state, the camera cannot be lifted, and all images shot by the camera at the moment are abnormal images.

Therefore, in the embodiment of the application, when the physical switch is in the locked state, all the characteristics of the abnormal images appear in the images shot by the camera, and the frame images in the preview image are analyzed to determine the state of the physical switch. If the physical switch is in the locked state, the camera can only shoot the frame images which are all abnormal images, and if the physical switch is in the opened state, the camera can shoot partial normal images or all normal images.

In order to save the time for determining the state of the physical switch, the embodiment of the application analyzes the frame image of the preset time in the preview image to determine the state of the physical switch, instead of using the frame image obtained by shooting after the camera is completely lifted. The camera is lifted from the social television completely, about 1.5s is needed, and the preset time can enable the frame image shot when the camera part is not shielded by the frame to be set to be 0.5s, so that the time for determining the physical on-off state can be saved.

However, the frame image is not the first frame image in the preview image captured by the camera after receiving the camera opening instruction, because the camera cannot be lifted immediately after receiving the camera opening instruction, and the first frame image may be all abnormal images and has no analysis value.

S200, if the frame image is a lock image, determining that the physical switch is in a locked state, wherein the lock image is an image acquired by the camera in the locked state of the physical switch, and the locked state of the physical switch indicates that the camera is not lifted. It should be noted that the frame image captured by the camera when the physical switch is in the locked state is different from the frame image captured by the camera when the physical switch is in the open state, because the camera can be raised when the physical switch is in the open state, the captured image may be a part of a normal image and a part of an abnormal image, and when the physical switch is in the locked state, the camera cannot be raised, and the captured images are all abnormal images.

In an exemplary embodiment, the controller is configured to perform the determining that the physical switch is in the locked state if the frame image is a lock image according to the following steps:

a color value for each pixel in the frame image is obtained. Specifically, the color value of each pixel is obtained according to the resolution of the frame image.

In the embodiment of the application, before the color value of each pixel in the frame image is obtained, the format of the frame image can be converted into the preset format.

The preview images are frames of images saved in NV21 encoding format. Specifically, the default format of an image acquired by a camera in the android system is NV21 coding. NV21 belongs to YUV420 format, and shares a set of UV every four Y, for example, in fig. 12, Y1, Y2, Y9, and Y10 share a set of V1 and U1, NV21 is a two-Plane mode, i.e., Y and UV are divided into two planes, and UV is interleaved storage. All Y is stored first, then UV interleaved, V is stored first, then U in NV21 encoded format.

However, in the process of picking up the color value of the pixel point by the frame image in the NV21 encoding format, because the color value of the pixel point of the frame image in the NV21 encoding format is composed of the separately stored Y and UV, the color value of the pixel point is obtained by obtaining the Y and the UV stored at different positions, and the difficulty in obtaining the color value of the pixel point is increased. Because obtaining the frame image in the NV21 coding format is not beneficial to obtaining the color value of the pixel point, the embodiment of the present application converts the obtained frame image in the NV21 coding format into a bitmap (bitmap) image with a color value that is easy to read, pixels of the bitmap image are all allocated with specific positions and color values, and the color value of each pixel is combined by RGB.

The specific method for converting the frame image in the NV21 encoding format into a bitmap image with RGB color values easy to read is as follows: according to a YuvImage functional interface class provided by the android system, an image byte array in an NV21 encoding format, image width and height information are input, a frame image in the NV21 encoding format can be converted into a byte stream in a JPEG format, and then the obtained byte stream can be decoded into a Bitmap image.

And determining the number of pixels of each line of the image lock in the frame image according to the color value of each pixel.

And if the proportion of the number of the pixels to the number of the pixels in each row of the image lock is larger than the preset proportion, determining that the physical switch is in a locked state.

In the embodiment of the application, the number of the image lock pixels in each row is counted, and if the proportion of the number of the image lock pixels in each row to the number of the pixels is greater than a preset proportion, which can be 90%, the physical switch is in a locked state.

acquiring a color value of each pixel of a first row of images in a frame image;

if the proportion of the number of the locking pixels to the number of the pixels is larger than the preset proportion, obtaining the color value of each pixel of the next row of images in the frame image, repeatedly executing the step of determining the number of the locking pixels according to the color value of each pixel until the proportion of the number of the locking pixels to the number of the pixels of the last row of images in the frame image is larger than the preset proportion, and determining that the physical switch is in a locking state.

It should be noted that, the number of lock pixels of the first row of images is determined, and if the ratio of the number of lock pixels of the first row of images to the number of pixels of the first row of images is greater than a preset ratio, which may be 90%, it is determined that the camera is not lifted, and it may also be determined that a real image of a captured peripheral image of the display device is approximately black after the camera is normally lifted. Specifically, referring again to fig. 12, the peripheral image of the display device displayed above the frame image is a dark scene, which may cause the ratio of the number of lock pixels to the number of pixels to be greater than the predetermined ratio. In order to accurately determine whether a frame image is a lock image, obtaining a color value of each pixel of a second row image of the frame image, executing a step of determining the number of lock pixels according to the color value of each pixel, judging the proportion of the number of lock images of the second row image to the number of pixels of the second row image and the preset occupation ratio, if the proportion of the number of lock images of the second row image to the number of pixels is greater than the preset occupation ratio, continuously judging the proportion of the number of lock images in a third row image to the number of pixels of the third row image until judging whether the proportion of the number of lock images of a last row image of the frame image to the number of pixels is greater than the preset occupation ratio, and if the proportion of the number of lock images of last row image to the number of pixels is greater than the preset occupation ratio, indicating that a physical switch is in a lock state.

In an exemplary embodiment, if the ratio of the number of lock pixels to the number of pixels is less than or equal to the preset duty ratio, it is determined that the frame image is not the lock image, and the color value of each pixel of the next row image is not acquired.

Specifically, when the preset proportion is 90%, if the proportion of the number of lock pixels to the number of pixels is less than or equal to 90%, it is determined that the frame image is not a lock image.

In an exemplary embodiment, the controller is configured to perform the determining the number of image-locked pixels per line in the frame image according to the color value of each pixel by:

acquiring image deviation; specifically, in order to obtain a better display effect on the display device, the original image obtained by the camera is corrected and processed in image quality, so that the obtained preview image has a certain difference from the original image obtained by the actual camera. For example, if the camera lock is not raised, the image captured by the camera is close to black (RGB values are (0, 0)), and after the image quality processing, the RGB values of the frame image of the preview image obtained are deviated from black by a certain amount. When the format of the frame image is RGB values, the image offsets include Sr (red offset), sg (green offset), and Sb (blue offset).

In addition, the step of obtaining the image deviation may be completed before the step of subtracting the color value of the pixel from the image deviation and taking an absolute value to obtain an absolute value of the color in the embodiment of the present application.

In an exemplary embodiment, the image deviation is determined according to a PQ image quality adjustment parameter.

Specifically, the preview image is an image obtained after the ISP processing. The ISP is a hardware processing module and is used for preprocessing an original image acquired by the photosensitive module of the camera to acquire a preview image with higher quality. The different adjustment of the parameters of the ISP module may affect the display effect of the preview image. The PQ Tools complete online image quality adjustment of the ISP through a network port or a serial port. The PQ picture quality adjustment parameter is a parameter for adjusting the image quality in the PQ Tools.

Subtracting the color value of each pixel from the image deviation, and taking an absolute value to obtain a color absolute value of each pixel;

and counting the number of lock pixels of each line of the image, wherein the lock pixels mean that the absolute value of the color is greater than the color threshold value.

if the frame image is the lock image, repeatedly executing the step of judging whether the frame image is the lock image at intervals of preset time until the repetition times reach the preset times;

counting the number of times that the frame image is a lock image, and if the number of times is equal to the number of repetitions, confirming that the frame image is a lock image.

Specifically, in order to make the detection of the state of the physical switch more accurate, the step of determining whether the frame image is the lock image may be repeated multiple times. If the preset times is set to be 3 times, after the frame image is determined to be the lock image for the first time, the step of judging whether the frame image is the lock image is repeatedly executed at intervals of preset time, after the frame image is determined to be the lock image for the second time, the step of judging whether the frame image is the lock image is repeatedly executed at intervals of preset time, and after the frame image is determined to be the lock image for the third time, the physical switch is confirmed to be in the locking state.

If the step of judging whether the frame image is the lock image is repeatedly performed at intervals of a preset time after the frame image is determined to be the lock image for the first time, determining that the frame image is not the lock image, and ending the determination of the locking state of the physical switch. The accuracy of determining the physical switch state of the embodiment of the application can be ensured by judging whether the frame image is the lock image for many times.

In an exemplary embodiment, the controller is further configured to perform the detecting whether the camera is lifted within a preset time according to the following steps: and if the frame image is not the lock image, determining that the physical switch is in an open state, wherein the physical switch is in the open state and indicates that the camera is lifted.

Specifically, if the frame image is not a lock image, it means that there is a case where the proportion of the number of lock pixels of one line of the frame image to the number of pixels is less than or equal to a preset proportion, which indicates that the camera has shot a normal image, and thus it is determined that the physical switch is in an on state.

In one example, the controller is configured to perform the following steps of detecting whether the camera is lifted within a preset time:

and acquiring a 0.5s frame image in the preview data, and converting the format of the frame image into an RGB format. Determining image deviation according to the PQ image quality adjustment parameter, obtaining an RGB value of each pixel of a first line image of a frame image, subtracting the image deviation from the RGB value of each pixel, taking an absolute value to obtain a color absolute value, if the color absolute value is greater than a color threshold value, taking the pixel as a lock pixel, counting the lock pixel of the first line image, if the proportion of the number of the lock pixels to the number of the first line image is greater than a preset duty ratio, continuously obtaining the RGB value of each pixel of a second line image of the frame image, determining the number of the lock pixels of the second line image according to the RGB value of each pixel, if the proportion of the number of the lock pixels to the number of the first line image is greater than the preset duty ratio, obtaining a color value of each pixel of a third line image until the proportion of the number of the lock pixels to the number of the last line image of the frame image is greater than the preset duty ratio, and determining that the frame image is a lock image. In order to increase accuracy, when the frame image is determined to be the lock image for the first time, repeated judgment is performed at intervals of 0.5s to determine whether the frame image is the lock image, and if all the results of the 3 times of detection indicate that the frame image is the lock image, it is determined that the physical switch is in the locked state. And after detecting that the frame images are all locking images for 3 times, determining that the camera is not lifted, and displaying a prompt message that the physical switch is in a locking state on the display.
