Description

Technical Field

[0001] The present application relates to the field of image acquisition technology, and in particular to a shooting method, a smart terminal and a storage medium. Background Art

[0002] Display resolution is the resolution of the display when displaying images. Resolution is measured in dots, and the "dot" on the display refers to pixels. The numerical value of display resolution refers to the number of horizontal pixels and vertical pixels on the entire visible area of ​​the entire display. For example, a resolution of 800×600 means that 800 pixels are displayed horizontally and 600 pixels are displayed vertically on the entire screen. The resolution of a camera refers to the camera's ability to resolve images, that is, the number of pixels of the camera's image sensor. The highest resolution refers to the camera's ability to resolve images at the highest level, that is, the camera's maximum number of pixels.

[0003] In the process of conceiving and implementing this application, the inventors found that there are at least the following problems: if the distance between the camera and the display is very close, even when the entire camera field of view is the data on the display, the camera pixels and the display pixels may match, resulting in the appearance of color stripes. The static dark patterns captured by the camera are called "moire fringes". They are caused by the mismatch between the camera resolution and the display resolution. It can usually be understood that the pixel of the mobile phone camera is larger than the display resolution. Because each pixel on the display cannot correspond one-to-one with each pixel on the mobile phone camera CMOS, the "black dots" between the pixels of the display are finally recorded, and there are the stripes you see. This interference phenomenon caused by different spatial frequencies causes a serious reduction in the quality of the captured image.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the invention

[0005] In response to the above technical problems, the present application provides a shooting method, comprising the following steps: in response to a shooting operation, adjusting the shooting field of view with the target object in the preview screen as the center, and then executing the shooting instruction.

The processed image frame can be displayed on the display unit 106. The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a telephone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0058] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0059] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0060] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072.

[0061] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Then, the processor 110 provides corresponding visual output on the display panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited here.

[0062] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0063] The memory 109 can be used to store software programs and various data. The memory 109 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0064] The processor 110 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, so as to monitor the mobile terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0065] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0066] although Figure 1 Not shown, the mobile terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0067] In order to facilitate understanding of the embodiments of the present application, the communication network system on which the mobile terminal of the present application is based is described below.

[0068] See also Figure 2 , Figure 2 A communication network system architecture diagram is provided for an embodiment of the present application, wherein the communication network system is an LTE system of universal mobile communication technology, and the LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204, which are connected in sequence for communication.

[0069] Optionally, UE201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0070] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 , etc. Optionally, eNodeB 2021 may be connected to other eNodeBs 2022 via a backhaul (eg, an X2 interface), and eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 may provide UE 201 with access to EPC 203 .

All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, which selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0072] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0073] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new network systems (such as 5G), etc., without limitation here.

[0074] Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0075] First embodiment

[0076] This application provides a shooting method. Figure 3 This is a flow chart of a photographing method according to an embodiment of the present application.

[0077] like Figure 3 As shown, in one embodiment, the shooting method includes: in response to the shooting operation, taking the target object in the preview screen as the center, adjusting the shooting field of view and executing the shooting instruction. Specifically, it can be divided into two steps:

[0078] S10: In response to the shooting operation, adjusting the shooting field of view with the target object in the preview image as the center.

[0079] For example, when the camera is shooting an image, the lens is aimed at the target object to be shot. Based on the distance between the camera and the target object, the shooting field of view at this time is often not in a suitable parameter position. Therefore, before shooting, the shooting field of view can be adjusted to a suitable parameter position for the current scene.

[0080] S20: Based on the adjusted shooting field of view, executing a shooting instruction to obtain a first target image.

[0081] Exemplarily, after the shooting field of view is adjusted to a suitable parameter position, the shooting instruction can be executed to obtain a first target image to obtain a high-quality shot image.

[0082] Through the above technical solution, this embodiment can achieve higher quality image acquisition, improve work efficiency, and thus enhance user experience.

[0083] Optionally, the target may include:

[0084] A target object is determined in response to a selection operation on an object in the preview image.

[0085] For example, in some application scenarios in life or work, it is necessary to aim the lens at some specific objects for shooting. At this time, the user can operate the options on the preview screen of the display screen, select the objects to be photographed in the screen, and enable the system to perform corresponding shooting operations for the selected objects.

[0086] Optionally, the target may include:

[0087] Monitor screen.

[0088] For example, in some application scenarios of life or work, it is necessary to shoot the screen displayed on the display, and the display screen can be used as a target object for shooting. Optionally, it can be first identified whether the current preview screen includes the display screen.

[0089] For example, in the process of shooting high-quality images, the shooting parameters of the display image are greatly different from those of other objects. Therefore, before shooting the image, the display image can be identified first. For example, in order to solve the problem of screen stripes when shooting the display, the pixels of the sensor in the camera can be set to include enough light beams to achieve high-quality display image shooting.

[0090] Optionally, the display screen may include:

[0091] The overall picture within the monitor outline.

[0092] Optionally, the shooting method may further include:

[0093] When a display outline is recognized in the preview image, the entire image within the display outline is used as the display image.

[0094] For example, in the process of identifying whether the preview image is a display image, the outline of the display may be firstly feature-recognized in the preview image. When the outline of the display is identified, the entire image within the outline of the display may be used as the image to be completely captured, and corresponding shooting parameters may be set. Optionally, the outline of the display may be identified by an AI recognition model.

[0095] Optionally, the display screen may include:

[0096] A partial image displayed on the monitor.

[0097] Optionally, the shooting method may further include:

[0098] When it is recognized that stripes appear on the full screen of the preview picture, the preview picture is used as the display picture.

[0099] During the shooting process, if the camera is closer to the screen, or even the entire camera's viewing range is the data on the display, the camera pixels and the display pixels may match, resulting in the appearance of color stripes. Exemplarily, in the process of identifying whether the preview picture is a display picture, it can be detected whether stripes appear in the preview picture. If stripes are detected in the preview picture, it can be determined that the current preview picture is a display picture. Furthermore, it can be determined whether the current preview picture is a partial picture displayed on the display according to the area range of the stripes in the preview picture.

[0100] Optionally, adjusting the shooting field of view may include:

[0101] Expand the shooting field of view.

[0102] For example, when the shooting field of view is not wide enough, the shooting field of view can be expanded to capture a more comprehensive scene.

[0103] Optionally, adjusting the shooting field of view may include:

[0104] The shooting field of view is expanded until the area proportion of the target object is less than a first threshold.

[0105] For example, when photographing an object, the field of view can be appropriately expanded so that the area of ​​the target object in the image occupies a proportion of the entire image area that is less than a preset first threshold. This can not only capture the entire image of the target object, but also eliminate stripe interference when photographing the display screen, thereby improving the captured image quality.

[0106] Optionally, adjusting the shooting field of view may include:

[0107] Expand the shooting field of view until no stripes appear on the monitor screen.

[0108] For example, when photographing a display screen, adjusting the photographing field of view to eliminate stripe interference can improve the quality of the captured image and enable the image to better display the color of the target object.

[0109] Optionally, adjusting the shooting field of view may include:

[0110] Reduce the shooting field of view.

[0111] For example, when photographing an object, the shooting field of view can be appropriately narrowed so that the captured image can finely reflect the detailed features of the target object, and it can also be adjusted to eliminate stripe interference when photographing the display screen, thereby improving the captured image quality.

[0112] Optionally, adjusting the shooting field of view may include:

[0113] The shooting field of view is reduced until the area ratio of the target object is greater than a second threshold.

[0114] For example, when photographing an object, the field of view can be appropriately reduced so that the area of ​​the target object in the image occupies a proportion of the entire image area that is greater than a preset second threshold. The close-up image can not only capture the detailed features of the target object, but also be adjusted to eliminate stripe interference when photographing the display screen, thereby improving the captured image quality.

[0115] Figure 4 It is a schematic diagram of a display screen of a shooting display according to an embodiment of the present application.

[0116] like Figure 4 As shown, optionally, the expanding the shooting field of view may include:

[0117] Increase the focal length of the camera; and / or, switch to a wide-angle lens.

[0118] For example, when photographing an object, the field of view can be appropriately expanded by increasing the focal length or switching to a wide-angle lens, so that the area of ​​the target object in the image occupies a smaller proportion of the entire image area, and the entire image of the target object can be fully captured. Figure 4 When the camera shoots the display screen of the monitor, it can appropriately expand the shooting field of view by increasing the focal length or switching to a wide-angle lens. It can be adjusted to eliminate stripe interference when shooting the display screen of the monitor and improve the image quality.

[0119] Optionally, reducing the shooting field of view may include:

[0120] Reduce the focal length of the camera; and / or, switch to a macro lens.

[0121] For example, when photographing an object, the shooting field of view can be appropriately narrowed by reducing the focal length or switching to a macro lens, so that the area of ​​the target object in the image occupies a larger proportion of the entire image area, so that the captured image can finely reflect the detailed features of the target object, and can also be adjusted to eliminate stripe interference when shooting the display screen, thereby improving the captured image quality.

[0122] Optionally, the shooting method may further include:

[0123] The first target image is displayed.

[0124] For example, after capturing an image of the target object, the first target image can be displayed on the display screen directly or indirectly. For example, by adjusting the shooting field of view, stripe interference can be eliminated when shooting the display screen, thereby improving the image quality of the captured and displayed images.

[0125] Optionally, the shooting method may further include:

[0126] The first target image is cropped to obtain a second target image including the target object.

[0127] For example, after capturing an image of the target object, the first target image can be appropriately cropped to obtain a second target image of a suitable proportion or size. For example, by adjusting the field of view and restoring the field of view through cropping, stripe interference can be eliminated when capturing a display image, thereby improving the quality of the captured image.

[0128] Optionally, the cropping the first target image may include:

[0129] The first target image is cropped along the outline of the target object.

[0130] Exemplarily, by identifying the outline of the target object, such as a display frame, the first target image can be cropped along the outline of the target object, thereby obtaining a second target image containing only the target object.

[0131] Optionally, the cropping the target image may include:

[0132] The first target image is cropped along a border that includes a minimum area of ​​the target object.

[0133] For example, when a target object including multiple frames, such as a wide-edge display, is identified, a second target image including only the display screen can be cropped along the frame with the smallest area of ​​the display. For example, by adjusting the field of view during the display shooting process and cropping to restore the field of view, stripe interference can be eliminated when shooting the display screen, thereby improving the quality of the captured image.

[0134] Optionally, the cropping the target image may include:

[0135] The first target image is cropped along the shooting field of view before the shooting field of view is adjusted.

[0136] For example, since the shooting field of view is adjusted during the process of capturing the first target image, the field of view before the adjustment can be recorded, so that the first target image can be cropped to obtain the second target image of the shooting field of view size range originally required by the photographer. For example, by adjusting the shooting field of view and cropping to restore the field of view, stripe interference can be eliminated when capturing the display screen, thereby improving the captured image quality.

[0137] Through the above technical solution, this embodiment can achieve higher quality image acquisition, improve work efficiency, and thus enhance user experience.

[0138] Second embodiment

[0139] The present application also provides an intelligent terminal, comprising a processor and a storage medium connected to each other, wherein the storage medium is used to store a computer program; the processor is used to read and run the computer program to implement the above-mentioned shooting method.

[0140] Figure 5 A schematic diagram of the photographing process implemented by a smart terminal according to an embodiment of the present application.

[0141] like Figure 5As shown, in one embodiment, during the process of capturing a target area of ​​a display screen, when a shooting operation is triggered, the smart terminal first identifies and confirms that the current preview screen includes the display screen, then adjusts the viewing angle of the preview screen to adjust the shooting field of view, and after capturing an image including the display screen, crops the target area.

[0142] If the camera of the smart terminal is very close to the display, or even when the entire camera framing range is the data on the display, the camera pixels and display pixels may match, resulting in color stripes. Exemplarily, when the camera of the smart terminal is far away from the display, the camera framing involves more objects, and in this case the display only occupies a part of the camera framing. In this case, the camera sampling unit pixel is greater than the display unit pixel, and the display has no stripes under imaging. Optionally, when the mobile phone is close to the screen, or even when the entire camera framing range is the data on the display. Only then will the camera pixels and display pixels match, resulting in color bars. My expectation is: when it is far away, there will be no color bars, but no other data except the display is needed, so the shooting field can be enlarged and then the shot image can be cropped to retain only the data of the area that needs to be retained on the display for final imaging. Thereby achieving the effect that the camera only shoots the data on the display without stripes.

[0143] For example, in the process of capturing the entire image of the display, the outline of the display may be identified through an AI recognition model.

[0144] Exemplarily, when shooting a portion of the content displayed on the display, stripes in the preview image may be identified, and if stripes exist, it is determined that the current preview image includes the display image.

[0145] Exemplarily, in the process of adjusting the display screen to expand the shooting field of view, the preview screen viewing angle may be adjusted by adjusting the focal length of the main camera or by switching to a wide-angle lens for shooting.

[0146] Exemplarily, during the process of adjusting the display image to expand the shooting field of view, the degree of adjustment of the preview image viewing angle can be adjusted until no stripes appear in the current preview image, or it can be adjusted until the proportion of the display contour area in the current preview image is less than a preset value.

[0147] Optionally, taking a mobile phone as an example, when the mobile phone is shooting a display screen, assuming that the display screen is 1920*1080 pixels, the sampling size of the mobile phone camera is 3968*2976 pixels. In order to shoot a display screen image without color stripes, the camera sampling pixels can be greater than or equal to the display screen pixels, satisfying the following preset ratio threshold β:

[0148] β=(3968 / 1920+2976 / 1080) / 2=2.4

[0149] That is, the ratio of the mobile phone screen display width to the display width of the display image on the mobile phone screen is greater than or equal to 2.4, and / or, the ratio of the mobile phone screen display length to the display length of the display image on the mobile phone screen is greater than or equal to 2.4.

[0150] Exemplarily, in the process of cropping the target area, the display outline can be cropped to obtain the image of the target area, or a manually selected designated area can be cropped to obtain the image of the target area, or the screen size before adjusting the shooting field of view angle can be cropped to obtain the image of the target area.

[0151] The smart terminal of this embodiment can improve the imaging quality of the content on the display, provide a simple, convenient and fast shooting interaction process, and improve the user experience.
