detailed description

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the structures related to the present invention are shown in the drawings.

Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as a process or method depicted as a flowchart. Although the flowcharts describe the various steps as a sequential process, many of the steps can be implemented in parallel, concurrently, or concurrently. In addition, the order of the steps can be rearranged. The process may be terminated when its operation is completed, but may also have additional steps not included in the figures. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

Embodiment 1

FIG. 1 is a schematic flowchart of a screen fill light photographing method according to Embodiment 1 of the present invention. The method may be performed by a screen fill light photographing device, where the device may be implemented by software and/or hardware, and generally integrated into a mobile terminal. . As shown in Figure 1, the method includes:

Step 101: When it is detected that the screen fill photo event is triggered, the control screen performs pre-filling with the first brightness.

Illustratively, the mobile terminal in this embodiment may specifically be a terminal device configured with a display screen, such as a mobile phone, a tablet computer, and a digital camera. The camera in this embodiment may specifically be a front camera fixed on the front side of the mobile terminal (on the same side as the screen), or a rotatable camera whose current position is on the front side of the mobile terminal.

Exemplarily, monitoring that the screen fill photo event is triggered may specifically refer to monitoring the user by pressing a button. The active mode triggers the screen fill light photo event, and may also refer to monitoring the mobile terminal to automatically trigger the screen fill light photo event. For example, when the camera in the mobile terminal is in the on state and the screen fill photo function is in the on state, after detecting that the user presses the camera button, the device is metered by an ambient light sensor, etc., when the metering result includes the current When the ambient light brightness is lower than the preset brightness threshold, the screen fills the photo event. It should be noted that when the camera is detected to be in the on state and the screen fill photo function is in the on state, the metering is started directly, and when the metering result includes the current ambient light level being lower than the preset brightness threshold. If the user presses the photo button, the screen fills the photo event. In addition, if the mobile terminal supports the face detection camera function, when the camera is detected to be in the on state and the current ambient light brightness is lower than the preset brightness threshold, if the face in the preview image meets the photographing requirement, the mobile terminal can automatically trigger the screen. Fill the photo event without the user manually pressing the camera button.

Exemplarily, it is detected that the screen fill photo event is triggered, which indicates that the current shooting environment is dark, and the fill light needs to be performed. At this time, the control screen performs pre-filling with the first brightness. The first brightness may be a preset fixed brightness or a brightness determined dynamically according to the current ambient light brightness. The content of the screen display in this embodiment is not specifically limited, and may be a photo preview interface or a solid color image.

Generally, the screen brightness of the mobile terminal can be adjusted by the user during the use of the user, or can be automatically adjusted by the ambient light sensor, so that the user can see the screen content and obtain better results when viewing the screen. To view the comfort level, the screen brightness at this time can be recorded as normal brightness. When the user performs a self-timer, the screen generally displays a preview screen before the screen fill photo event is triggered, and the screen brightness at this time is normal brightness. The first brightness in this embodiment is higher than the normal brightness to achieve the purpose of filling light.

Step 102: Control the camera to start capturing images continuously during the pre-filling process.

Illustratively, the image may be continuously captured at a time when the screen brightness is adjusted to the first brightness, or may be continuously captured at any time after the screen brightness is adjusted to the first brightness (including the screen brightness being from the first brightness) Adjust to the moment of the second brightness).

Specifically, the camera can be controlled to start capturing images continuously at a preset frequency. The preset frequency may be a fixed frequency or a dynamically changing frequency, and may be determined according to a specific image capturing strategy, which is not limited in this embodiment.

Step 103: The control screen performs main fill light with the second brightness until the camera ends the image capture.

The second brightness is different from the first brightness.

For example, the timing at which the camera ends the image capturing is not limited in this embodiment, and may be determined according to a specific image capturing strategy. For example, if the image capture strategy is to capture the number of frames of the image as N, then when it is detected that the captured image reaches N, the image capture can be ended.

In this embodiment, the second brightness may be a preset fixed brightness, or may be a brightness dynamically determined according to the current ambient light brightness. The content of the screen display in this embodiment is not specifically limited, and may be a photo preview interface or a solid color image.

Step 104: Select at least one frame of the target image from the captured images, and generate a photo according to the at least one frame of the target image.

Illustratively, the selection of the target image may be performed according to factors such as the time at which the image was captured or the quality of the image. For example, the moment when the screen brightness is adjusted from the first brightness to the second brightness is recorded as the reference time, and the image whose time difference between the captured time and the reference time is less than the preset time difference threshold is selected as the target image, preferably The image whose capture time is closest to the reference time can be selected as the target image. For example, an image quality-related index such as brightness, sharpness, and color saturation of an image may be evaluated, and an image whose quality conforms to the standard may be selected as a target image. After the target image is selected, the target image is encoded and processed to generate a photo, and the specific generation manner is not limited.

The screen fill light photographing method provided by the first embodiment of the present invention detects that the fill light photographing event is triggered, the control screen performs pre-filling with the first brightness, controls the camera to continuously capture the image during the pre-filling process, and then controls the screen. The main fill light is performed at a second brightness different from the first brightness until the camera ends the image capture, and finally at least one frame of the target image is selected from the captured images and a photo is generated. By adopting the above technical solution, the fill light phase is divided into two stages of pre-fill light and main fill light, each stage corresponds to different screen brightness, and the image is maintained during the process of switching from the pre-fill light stage to the main fill light stage. Capture, enabling the camera to capture more images with different fill effects, expanding the selection of target images and improving photo quality.

Based on the above embodiment, the second brightness is higher than the first brightness. The advantage of this setting is that the fill light brightness undergoes a progressive process, which can assist the camera's auto focus, and at the same time allow the user's eyes to gradually adapt to the change of the screen brightness, so that the pupil of the user's eyes is pre-filled. The stage is reduced in advance (the dizzy eyes of the human eye are larger in order to adapt to the darkness, and the red-eye phenomenon is likely to occur when photographing), and the red-eye phenomenon is improved.

Embodiment 2

FIG. 2 is a schematic flowchart of a screen fill light photographing method according to Embodiment 2 of the present invention. The present embodiment is optimized based on the foregoing embodiment. In this embodiment, the first brightness and the second brightness are fine. The first brightness is within the system default brightness adjustment range of the screen, and the second brightness is greater than the maximum brightness of the system default brightness adjustment range and less than or equal to the maximum brightness supported by the screen.

Further, the control screen performs the main fill light with the second brightness until the camera ends the image capture, and specifically includes: switching the brightness adjustment range of the screen from the system default brightness adjustment range to the maximum adjustment range supported by the screen; The second brightness performs the main fill until the camera ends the image capture.

Correspondingly, the method of this embodiment includes the following steps:

Step 201: When it is detected that the screen fill photo event is triggered, the control screen performs pre-filling with the first brightness.

In this embodiment, the first brightness is within a system default brightness adjustment range of the screen, and the second brightness is greater than a maximum brightness of the system default brightness adjustment range and less than or equal to a maximum brightness supported by the screen.

Among them, the maximum brightness supported by the screen can specifically refer to the maximum brightness that can be achieved by the screen on the hardware level. The material, internal structure and illumination principle of the screen used by the mobile terminal are different, and the brightness of the screen is limited by these hardware indicators. There is a certain limit, which can be understood as the maximum brightness supported by the screen described in this embodiment. The brightness of the limit brightness is very high, and is usually not used in the actual application process of the mobile terminal. If the limit brightness is used, not only the power consumption is large, but also the human eye is not suitable for viewing, the user may have a glare, so the screen system The maximum value of the default brightness adjustment range will be less than the limit brightness.

For example, if the above limit brightness is 480, then the system default brightness adjustment range of the screen can be 0-255, or 30-255, because the brightness of 0-30 is too low to properly view the screen. For the screen fill function, the brightness in the system default brightness adjustment range may not meet the fill light requirement, and higher brightness is needed to achieve a better fill light effect. Therefore, the second brightness in this embodiment is greater than the system. The maximum brightness of the default brightness adjustment range is less than or equal to the maximum brightness supported by the screen, that is, a brightness between 256-480, which is supplemented by the brightness interval that has not been effectively utilized before, effectively improving the fill light effect.

Preferably, the first brightness is the maximum brightness of the system default brightness adjustment range (such as 255), and the second brightness is the maximum brightness supported by the screen (such as 480). The advantage of this setting is that the first brightness and the second brightness are both fixed values, reducing the time for dynamically determining the first brightness and the second brightness, and improving the fill light. Speed, and the brightness is high enough to ensure a better fill light effect.

Step 202: Control the camera to continuously capture images during the pre-filling process.

Step 203: Switch the brightness adjustment range of the screen from the system default brightness adjustment range to the maximum adjustment range supported by the screen.

Exemplarily, the preset system file node can be read and turned on to switch the brightness adjustment range of the screen from the system default brightness adjustment range to the maximum adjustment range supported by the screen. For example, a system file node may be added in advance in the mobile terminal, and the brightness adjustment range of the screen may be switched by controlling the opening and closing of the system file node. When the system file node is in the off state, the brightness adjustment range of the screen is the system default brightness adjustment range, such as 0-255 in the above example; when the system file node is in the off state, the brightness adjustment range of the screen is supported by the screen. The maximum adjustment range, such as 0-480 in the above example. The preset system file node is generally in a closed state, and when the screen brightness needs to be adjusted to the second brightness, the preset system file node is read and opened.

Step 204: The control screen performs main fill light with the second brightness until the camera ends the image capture.

Exemplarily, after the main fill light is finished, the preset system file node can be closed, and the brightness adjustment range of the screen is restored to the system default brightness adjustment range. Further, it is also possible to control the brightness of the screen to switch to the preview.

Step 205: Select at least one frame of the target image from the captured images, and generate a photo according to the at least one frame of the target image.

The screen fill light photographing method provided by the second embodiment of the present invention further optimizes the first brightness and the second brightness, and fully utilizes the brightness interval that is not effectively utilized in the existing mobile terminal to fill light, thereby effectively improving the fill light. The effect is to improve the quality of the photo.

Step 301: The front camera in the mobile terminal is in an open state.

Step 302: Determine whether the screen fill function is enabled. If yes, execute step 303; otherwise, perform step 309.

Step 303: Determine whether the current ambient light brightness is lower than a preset brightness threshold. If yes, execute step 304; otherwise, perform step 309.

Step 304: When it is detected that the photo button is triggered, the control screen performs pre-filling with the first brightness.

In this embodiment, the first brightness is the maximum brightness of the system default brightness adjustment range, and the second brightness is the maximum brightness supported by the screen.

Step 305: Control the camera to continuously capture images during the pre-filling process.

Step 306: Switch the brightness adjustment range of the screen from the system default brightness adjustment range to the maximum adjustment range supported by the screen.

Step 307: The control screen performs the main fill light with the second brightness until the camera ends the image capture, and restores the screen brightness to the brightness at the time of preview.

Step 308: Select at least one frame of the target image from the captured images, and generate a photo according to the at least one frame of the target image.

Step 309: Perform a non-fill light photo related operation.
