Detailed ways

The technical solutions in the embodiments of the present application are described below with reference to the accompanying drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present application without creative efforts are within the scope of the present application.

In recent portable terminals or other devices having a camera function, the size of the display screen is gradually increased in size, thereby making the terminal having a display screen of five inches or larger size popular. When a larger display screen is used, the distance between the position of the front camera for shooting in the self-timer mode and the center of the display screen displaying the self-timer preview screen increases. The problem caused by this increase in distance is that when shooting in the self-timer mode, the user's eyes appear unnatural in the self-portrait photographs taken, and the eyes look a little underneath.

As shown in Figure 2, it is a schematic diagram of the terminal. The terminal includes a display unit 210 and a front camera 220 disposed on the same surface as the display unit 210. In a terminal having a size of five inches or more, the distance between the center of the display unit 210 and the front camera 220 is several inches. In order to take a picture using the front camera 220, if the user views the self-timer preview screen displayed on the display unit 210 to confirm the characteristics of the user, the user's eyes gaze away from the center of the display unit 210 of the front camera 220. Since the front camera 220 does not look at the position of the front camera 220 when taking a self-portrait photo of the user, the user's eyes appear unnatural in the self-timer photo.

In one implementation, in order to avoid this phenomenon, as shown in FIG. 3, a schematic diagram of displaying a self-timer preview screen and a mini self-timer preview screen when the terminal uses the front camera to perform shooting. In the scheme shown in FIG. 3, when the front camera 220 is self-photographed, the self-timer preview screen is displayed on the display unit 210 to confirm the user's shooting posture, and the mini self-timer preview screen is displayed at a position close to the front camera 220, thereby the user The eyes can look at the mini self-timer preview screen near the front camera 220 at the time of shooting.

However, in the solution shown in FIG. 3, after the user confirms the user's shooting posture using the self-timer preview screen, the user does not necessarily realize that it is necessary to turn the gaze to the mini self-timer preview screen at the shooting time, but still stays on the self-timer preview screen. Can't really make the eyes more natural in the self-timer photos taken by the user during self-timer.

In the embodiment of the present application, in order to better guide the user's gaze during the self-timer, in a possible implementation manner, when the terminal detects the self-timer shooting request, the self-timer preview screen displayed on the display screen is reduced to a self-timer by a gradual change. The guide screen is displayed, and the self-timer guide screen is close to the position of the front camera. Then, according to the gradual process of the self-timer preview screen, the user can focus on the self-timer guide screen, that is, the position close to the front camera, so that the user's eyes in the self-timer photographs are relatively natural, and the direction of the user's eyes is seen. Close to the camera lens. Alternatively, the similarity between the self-timer guide screen and the self-timer preview screen is greater than a certain threshold.

In another possible implementation manner, when detecting the self-timer shooting request, the terminal may normally display, lighten (weaken) display or blur display the self-timer preview screen, and the self-timer guide screen is superimposed on the self-timer preview screen and The position display of the front camera is approached, wherein the self-timer guide screen is not related to the self-timer preview screen. Alternatively, while the self-timer guide screen is displayed, the voice can be played to prompt the user to pay attention to the self-timer guide screen. The self-timer guide screen may be in the form of a picture, a text, an animation, etc., and is not limited. Because the user's gaze is attracted by the self-timer guide picture, the user's eyes in the taken self-timer picture are more natural.

The present application is applicable to various devices that provide camera functions. Illustratively, it may include general handheld electronic terminals such as smart phones, portable terminals, terminals, Personal Digital Assistant (PDA), Portable Media Player (PMP) devices, notebook computers, notebooks ( Note Pad), Wireless Broadband (Wibro) terminals, personal computers (PCs), and smart PCs. The application is also applicable to non-portable electronic devices, such as smart televisions that provide camera functionality.

As shown in FIG. 4, it is a schematic diagram of an embodiment of a method for self-timer guiding in the embodiment of the present application, including:

401. The terminal displays a self-timer preview screen on the display screen.

In the embodiment of the present application, before the terminal displays the self-timer preview screen on the display screen, the terminal receives an opening instruction to the front camera; the terminal turns on the front camera according to the opening instruction; and the terminal acquires an image of the at least one object through the front camera. That is, when the front camera of the terminal is turned on, an image of at least one object can be captured, and then an image of at least one object is displayed on the display screen, and a screen displayed on the display screen is called a self-timer preview screen. Wherein at least one object may refer to at least one character object. The position of the front camera in the terminal is not limited, and may be at the top left end, the top right side, the top end of the terminal, or at the bottom left end and the bottom end right side of the terminal. Alternatively, the captured image of at least one object represents the entire image or approximately the entire image, for example, capturing at least 80% of the image of the image.

402. The terminal acquires a self-timer shooting request.

In the embodiment of the present application, when the front camera of the terminal is turned on, a self-timer shooting request is acquired. The self-photographing request is at least one of the following: the processor detects a request generated by operation of a shutter button of the front camera, and the processor detects a request generated by the input biometric in accordance with the preset biometric.

The self-timer shooting request may be a self-timer shooting request generated by a user pressing a button (a long press, a light press, a heavy press, etc.), a click (click, double tap, etc.) on a shooting button, a shutter button, or a shooting icon of the terminal shooting interface. . As shown in FIG. 5A, a schematic diagram of obtaining a self-timer shooting request for the terminal is shown.

Alternatively, the preset voice is stored in the terminal, and the target sound 201 of the user is detected by the microphone. For example, when the target sound 201 can include sounds such as “photographing”, “smile”, “start”, etc., the preset voice saved in the terminal is matched. , generate a self-timer shooting request. As shown in FIG. 5B, another schematic diagram of obtaining a self-timer shooting request for the terminal is shown.

Alternatively, the terminal performs the biometric 202 identification to generate a self-timer shooting request; for example, when the terminal detects the user's iris, eye movement trajectory, such as a biometric such as “smile” or “blink”, or the terminal detects the user fingerprint and the preset gesture. Etc., the terminal generates a self-timer shooting request. As shown in FIG. 5C, another schematic diagram of obtaining a self-timer shooting request for the terminal is shown.

Or, the terminal is configured with a timer, and the timer is set with a preset duration, for example, a duration of 5s, 3s, etc., and the preset duration indicates that the front camera is turned on after the preset front camera is turned on, and the operation of the front camera is turned on here. The generated request is also a self-timer shooting request. As shown in FIG. 5D, another schematic diagram of obtaining a self-timer shooting request for the terminal is shown. It should be noted that, in the implementation shown in FIG. 5D, steps 401 and 402 are one step.

It should be understood that after the terminal opens the front camera, the user can set the camera position, make the desired expression or face, select the desired angle, etc. before taking the self-timer photo. The manner in which the terminal obtains the self-timer shooting request includes, but is not limited to, any one of FIG. 5A to FIG. 5D.

403. The terminal reduces the self-timer preview screen displayed on the display screen to a self-timer guide screen according to a self-timer shooting request, and takes a photo to obtain a self-timer photo.

In the embodiment of the present application, the terminal reduces the self-timer preview screen displayed on the display screen to a self-timer guide screen according to the self-timer shooting request, and takes a photo to obtain a self-timer photograph. The self-timer preview screen may be reduced to a self-timer guide screen, or the self-timer guide screen may be a part of the self-timer preview screen, and may be a central part, or may be any part of the top, bottom, left, and right, and the specific part is not limited. That is, it can be understood that the screen similarity between the self-timer preview screen and the self-timer guide screen is greater than a certain threshold. Illustratively, a certain threshold may be 50%, which may be determined according to actual conditions.

If the self-timer preview screen is reduced to a self-timer guide screen as an example, the terminal receives a self-timer shooting request. In the future, according to the self-timer shooting request, the first self-timer preview screen displayed on the display screen at the first moment can be reduced to the second self-timer preview screen display by the gradual change method at the second moment, and the second self-timer preview screen is displayed. The third time is reduced to the self-timer guide screen display. Wherein, the linear distance between the center position of the second self-timer preview screen and the front camera is smaller than the linear distance between the center position of the first self-timer preview screen and the front camera, and the linear distance between the center position of the self-timer guide screen and the front camera is smaller than the second The linear position of the center position of the self-timer preview screen and the front camera. It should be understood that the size of the self-timer guide screen can be an empirical value, which can be determined according to the actual situation. In this way, the user's gaze can be moved along with the position of the self-timer preview screen, and the center position of the self-timer guide screen is closer to the front camera, the terminal receives the self-timer shooting request to start the countdown, and when the camera self-timer preview screen is zoomed out, the countdown is performed. The time has come, so the terminal takes a photo to get a self-portrait photo.

It should be noted that, after receiving the self-timer shooting request, the terminal starts counting down, and the degree of reduction of the self-timer preview screen may be related to the countdown. Assume that the self-timer guide screen size is 1/6 of the size of the self-timer preview screen, and the countdown has 3 seconds. When the remaining 2.5s, the self-timer preview screen is reduced to 5/6. When the remaining 2s, the self-timer preview screen is reduced to 2/3, and the remaining 1.5s is The self-timer preview screen is reduced to 1/2. When the remaining 1s, the self-timer preview screen is reduced to 1/3. When the remaining 0.5s, the self-timer preview screen is reduced to 1/6, which is the size of the self-timer guide screen.

FIG. 15 is a schematic diagram of another embodiment of a terminal in the embodiment of the present application, where the terminal is described by using a mobile phone as an example, and FIG. 15 is a partial structure of the mobile phone related to the terminal provided by the embodiment of the present application. Block diagram. Referring to FIG. 15, the mobile phone includes: a front camera 1500, a radio frequency (RF) circuit 1510, a memory 1520, an input unit 1530, a display 1540, a sensor 1550, an audio circuit 1560, and a wireless fidelity (WiFi) module 1570. , processor 1580, and power supply 1590 and other components. It will be understood by those skilled in the art that the structure of the handset shown in FIG. 15 does not constitute a limitation to the handset, and may include more or less components than those illustrated, or some components may be combined, or different components may be arranged. The lens of the front camera 1500 can be disposed on the same surface as the display 1570, that is, on the front surface of the mobile phone. The position and number of the front camera 1500 or the lens can be implemented differently.

According to an embodiment of the present application, the lens of the front camera 1500 of the mobile phone may be located at the top of the mobile phone (left, center, right), or at the bottom of the mobile phone (left and right), and used in the lens of the front camera 1500 of the mobile phone. In the self-timer mode of capturing at least one character image, the self-timer preview screen is displayed on the display 1540, and the user can adjust the photographing posture according to the self-timer preview screen, and when the mobile phone receives the self-timer shooting request, the self-timer preview screen can be gradually reduced to a self-timer guide screen. Or, the self-timer guide screen is superimposed on the self-timer preview screen (the self-timer preview screen is not related to the self-timer guide screen), and the distance between the center position of the self-timer guide screen and the front camera 1500 is smaller than the center position of the self-timer preview screen and the front camera 1500 distance.

In this manner, before the user operates the shutter button or touches the image on the camera to "photograph", the user's line of sight is guided from the self-timer preview screen onto the self-timer guide screen, and the self-timer guide screen is close to the lens of the front camera 1500. Therefore, when viewing the self-timer guide screen, the user's eyes gaze in a direction close to the lens of the front camera 1500, so that the image finally captured by the front camera 1500 appears natural. That is, the user's eyes in the final captured image are usually looking straight ahead, rather than looking down. As described above, in the conventional device, the self-timer preview screen is displayed on the entire display screen, so that the user's eyes usually just look at the center of the screen before taking a picture, and since the lens of the front camera 1500 is located above the display screen, In the final captured photo, the user's eyes appear to look down.
