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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic flow chart diagram illustrating an image acquisition control method according to an embodiment of the present disclosure. The image acquisition control method disclosed by the embodiment of the disclosure can be applied to a terminal, the terminal comprises a display panel and an electronic device of an image acquisition device, such as a mobile phone, a tablet computer, a personal computer, and the like, and the image acquisition device can be used as a front camera of the terminal.
The display panel includes a first display area, and the image pickup device is disposed below the first display area. The shape and area of the cross section of the plane in which the display panel is located to the angle of view of the image pickup device may be the same as those of the first display region, and of course, the area and shape of the first display region may be set slightly larger in consideration of redundancy.
The first display area is an Organic Light Emitting Diode (OLED) display panel, and the Organic Light Emitting Diode can have a high transmittance, so that the image acquisition device can acquire an image on the front side of the terminal through the first display area. Wherein the first display area is not limited to one area nor one type of area.
As shown in fig. 1, the image acquisition control method may include the steps of:
in step S1, when the terminal receives an instruction to capture an image by the image capture device, controlling the first display area to pause displaying within a preset time period in which the display panel displays a preset frame image, wherein the preset time period is shorter than a human eye visual response time;
in this embodiment, the preset time period refers to a pre-specified time period in the time period for displaying the preset frame image. For example, the period of displaying the preset frame image is [ T1, T2], where T1< T2; the preset time period may be [ T3, T4], wherein T1< T3< T4< T2.
Optionally, a plurality of preset time periods may be determined in the time period for displaying the preset frame image, and each preset time period is less than the human eye visual response time. Each preset time period may include a first sub-preset time period and a second sub-preset time period, and the first sub-preset time period and the second sub-preset time period may be different but are both smaller than the human eye visual response time.
In this embodiment, the preset frame image may be any image frame that satisfies the preset condition after the image capturing apparatus receives the instruction to capture an image. Preferably, the preset frame image is one or more frames among a plurality of consecutive image frames for displaying the same image, and the one or more frames do not include the first frame among the plurality of consecutive frames.
Wherein the human eye visual response time may be 10 ms.
In step S2, the image capturing apparatus is controlled to capture an image within the preset time period.
In an embodiment, when the terminal receives an instruction to capture an image through the image capture device, if the display panel is displaying the image, the first display area may be controlled to pause displaying within a preset time period in which the display panel displays a preset frame image.
Because the image watched by human eyes has visual residue, the first display area is only paused in the preset frame, the preset time period is less than the human eye visual response time, the human eyes still can leave the image of the previous frame of the preset frame, the first display area is not perceived to be paused in the preset time period, the image of the previous frame of the preset frame generally has little difference with the image of the preset frame, the image left by the human eyes and the image of the preset frame displayed in the second display area of the display panel still can form an image, and therefore the watching experience of a user is hardly influenced.
And when the first display area is paused, the first display area can not shield the image acquisition equipment due to the display of the image, so that the image acquisition equipment can be controlled to acquire clear images within the preset time period. Therefore, the image is collected through the image collecting equipment under the screen under the condition that the watching experience of the user is not influenced.
In the related art, the strategy for controlling the image capturing device to capture the image is that only the user needs to perform image capturing, that is, the image capturing device is controlled to be turned on, and the user instructs to turn off. According to the embodiment of the disclosure, it is considered that the image disappears when the image acquisition device is opened in the related art, and the image is visually interrupted to influence the watching experience of the user. The embodiment of the disclosure considers both image acquisition and image display, starts the image acquisition device and stops image display within a short enough time (i.e. less than the user visual response time) within an image display period, i.e. controls the process of executing one-time image acquisition to be executed within a plurality of discontinuous periods, including one or more on-off-on processes, and the duration of each "on" is short enough and less than the user visual response time, so that the image acquisition operation does not affect the visual effect of the user viewing the image.
Fig. 2 is a schematic flow chart diagram illustrating another image acquisition control method according to an embodiment of the present disclosure. As shown in fig. 2, the display panel further includes a second display region, wherein the second display region may be an organic light emitting diode display panel, or may be a liquid crystal display panel, preferably an organic light emitting diode display panel.
In one embodiment, the transmittance of the first display region is higher than that of the second display region, for example, the transmittance of the first display region may be greater than or equal to 90% when no image is displayed, wherein the transmittance of the first display region may be increased by reducing the density of unit pixels in the first display region (for example, increasing the area of pixels, reducing wiring), changing the material of the cathode and anode of the organic light emitting diode in the first display region (for example, using a material with a transmittance higher than that of a magnesium-silver alloy in the prior art), and the like.
Wherein the controlling the first display area to pause display within a preset time period in which the display panel displays a preset frame image comprises:
in step S11, in the process that the display panel displays the same image for N consecutive frames, the first display area is controlled to pause display within a preset time period corresponding to a preset frame in the N frames, and the second display area is controlled to continue to display within the preset time period corresponding to the preset frame.
In one embodiment, when the terminal receives an instruction to capture an image by the image capture device, the number of frames of the same image displayed by the display panel may be extended, for example, the same image may be displayed for N consecutive frames. Embodiments of the present disclosure are mainly illustrated below in the case where N ═ 2.
For example, the display panel may display each image for one frame before receiving an instruction to capture an image by the image capture device, and may display each image for 2 frames consecutively after receiving an instruction to capture an image by the image capture device. In the process of continuously displaying 2 frames of the same image, the first display area can be controlled to pause display in the preset time period corresponding to the preset frame of the two frames, and the second display area can be controlled to continue to display in the preset time period corresponding to the preset frame.
The preset frame may be the 1 st frame of the 2 frames, or may be the 2 nd frame of the 2 frames.
Under the condition that the preset frame is the 1 st frame in the 2 frames, because the image watched by human eyes has visual residual, the first display area is only paused in the 1 st frame, the image of the previous frame on the 1 st frame still remains by the human eyes, the difference between the image of the previous frame on the 1 st frame and the image of the 1 st frame is generally small, so the image remained by the human eyes and the image of the 1 st frame displayed in the second display area in the display panel can still form an image, and the image which is not displayed in the 1 st frame on the first display area can be displayed in the 2 nd frame, so that the user can still acquire the information contained in the first display area, and the watching experience of the user is not influenced to a greater extent.
Under the condition that the preset frame is the 2 nd frame of the 2 nd frames, because the image watched by human eyes has visual residual, the first display area is only paused in the 2 nd frame, the image of the 1 st frame still remains by the human eyes, and the image of the 2 nd frame is the same as the image of the 1 st frame, so the image residual by the human eyes and the image of the 2 nd frame displayed in the second display area of the display panel can form a continuously displayed image, and the watching experience of a user is not influenced.
Fig. 3 is a timing diagram illustrating a first display region of the display panel in the process of displaying the same image for N consecutive frames according to an embodiment of the disclosure.
As shown in fig. 3, when the signal is at a high level, the pixel unit in the first display region is turned off, and when the signal is at a low level, the pixel unit in the first display region is turned on, so that when the display panel continuously displays 2 frames of the same image, and when the display panel displays the 1 st frame of image, the pixel unit in the first display region receives the signal at the high level for resetting, and then receives the signal at the low level for turning on the pixel unit to display the image, and when the display panel displays the 2 nd frame of image, the pixel unit in the first display region always receives the signal at the high level for keeping, thereby suspending displaying the image.
When the display panel displays the 1 st frame image and the 2 nd frame image, the pixel units in the second display area receive the high-level signal for resetting, and then receive the low-level signal to start the pixel units to display the image.
Optionally, the preset frame includes a frame other than the 1 st frame in the N frames.
In one embodiment, in the case that the display panel displays the same image for N consecutive frames, the first display region may be controlled to pause display in a period corresponding to a frame after the 1 st frame in the N frames, and accordingly, it may be ensured that the first display region has already displayed the image whose display is paused before the first display region is paused to be displayed, so that the image left in the eyes of the user can perfectly compose one image with the image displayed in the second display region while the first display region is paused to be displayed, so as to provide a better viewing experience for the user.
Optionally, N ═ 2.
In one embodiment, the same image can be displayed in 2 consecutive frames, so that a plurality of frames of images cannot be displayed continuously, and the influence on the viewing experience caused by the fact that a user views a plurality of images continuously is avoided.
Fig. 4 is a schematic flow chart diagram illustrating another image acquisition control method according to an embodiment of the present disclosure. As shown in fig. 4, the controlling of the first display region to pause display for a preset time period in which the display panel displays a preset frame image includes:
in step S12, when the first display area displays the preset frame image, the pixel unit rows in the first display area are controlled to pause display for one or more preset time periods during the starting process.
In one embodiment, the pixel units in the first display area may be started line by line in a line scanning manner, and in the process of starting the pixel unit line, the pixel unit line may be controlled to pause display within one or more preset time periods, so that within the preset time, the pixel unit line that is paused display may not cause a shield to the image acquisition device due to image display, and further the image acquisition device may be controlled to acquire an image through the pixel unit line within the preset time period.
In one embodiment, the rows of pixel cells in the first display region may be simultaneously turned on for a plurality of consecutive rows, so that the image capture device may capture an image through the plurality of rows of pixel cells while the plurality of rows of pixel cells are paused.
Because light can diffract in the transmission process, when an image acquisition device acquires an image through one pixel unit row, the image acquisition device may acquire an image with serious diffraction, so that the image is unclear. According to the embodiment, the image can be acquired through the pixel unit rows, so that the problem of light diffraction in the image acquisition process is relieved or even avoided, and a clear image is acquired.
Fig. 5 is a schematic flow chart diagram illustrating yet another image acquisition control method according to an embodiment of the present disclosure. As shown in fig. 5, the method further comprises:
in step S3, images are combined into one image according to the position of each row of pixel units from the time when the image capturing device captures images when the first row of pixel units pauses to display within a preset time period to the time when the image capturing device captures images when the last row of pixel units pauses to display within a preset time period.
In an embodiment, during the period of pausing display of each pixel unit row, only one row of images is acquired through the pixel unit row, so that the image acquisition device acquires the images from the time when the first row of pixel units pauses display within a preset time period to the time when the last row of pixel units pauses display within the preset time period, and the images are synthesized into one image according to the position of each row of pixel units, so that a complete image shot through the first display area can be obtained.
Preferably, the one or more preset time periods are a plurality of preset time periods.
Because the time period for opening one pixel unit row is short, although the image can be acquired by pausing and displaying a preset time period for the image acquisition device to acquire the image within the time period for opening the pixel unit row, the viewing experience of the user can be seriously affected by too long pause time, so that the preset time period for setting pause is also short, which may cause underexposure of the image acquisition device to acquire the image.
According to the embodiment of the disclosure, a plurality of preset time periods are configured to suspend displaying for the image acquisition equipment to acquire images, and on the basis of ensuring that each preset time period is not too long, the total duration of the plurality of preset time periods can be prolonged, which is beneficial to ensuring that the images acquired by the image acquisition equipment are enough to obtain exposure.
It should be noted that, the image capturing device may capture the same image in multiple preset time periods, or capture different images, and in this embodiment, it is ensured that the image captured by the image capturing device has enough exposure, and for the image capturing device to capture the same image in multiple preset sub-time periods, the image capturing device may respectively perform one exposure in each preset time period, and then superimpose the images respectively obtained by exposure in the sub-multiple preset time periods to obtain one image with enough exposure.
Fig. 6 is a timing diagram illustrating a pause of display of a pixel unit row in a plurality of preset time periods during a turn-on process according to an embodiment of the disclosure.
As shown in fig. 6, for a certain pixel unit row, during the time period that the pixel unit row is turned on, the display may be suspended for 4 preset time periods.
Optionally, the preset frame is one frame or a discontinuous plurality of frames.
In an embodiment, the first display area may be controlled to pause display in a period in which the display panel displays one frame of image, or may be controlled to display in a period in which the display panel displays discontinuous multiple frames, specifically, may display as needed.
For example, more exposure is not required, the first display region may be controlled to pause display in a period of time in which the display panel displays one frame of image, so that the first display region may be prevented from displaying an image as little as possible, which is beneficial to ensuring the viewing experience of a user.
For example, more exposures are required, the first display region may be controlled to display in a time period in which the display panel displays discontinuous multiple frames, so that the image acquisition device can acquire an image in the time period of the discontinuous multiple frames, and it is ensured that the image acquired by the image acquisition device has enough exposures.
And the pause display of the first display area is in discontinuous multiframes instead of continuous frames, so that the condition that the displayed image of the last frame is remained in eyes when a user watches the pause displayed frame can be still ensured, and the watching experience of the user is ensured.
It should be noted that, the image capturing device may capture the same image in a multi-frame time period, or capture different images, and in this embodiment, it is ensured that the image captured by the image capturing device has enough exposure, and for the image capturing device to capture the same image in the multi-frame time period, the image capturing device may respectively perform one exposure in each frame time period, and then superimpose images respectively obtained by exposure in a plurality of sub-time periods to obtain one image with enough exposure.
