Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

In order to improve the image shooting quality of the shooting device under lower environmental brightness, an embodiment of the present invention proposes an image shooting method, which can improve the image quality of the captured image captured by the shooting device under lower environmental brightness. In the embodiment, in order to make the shooting device perform image shooting under the ideal environmental brightness, if the shooting device does not include the light supplement device, or the supplement light device of the shooting device has a poor supplement light effect, it can and has better performance. The mobile terminal of the light supplement device establishes a communication connection, so that the ambient brightness value of the photographing device can be adjusted by the light supplement device of the mobile terminal. As shown in Figure 1a, the photographing device 10 can be connected to the data interface of the mobile terminal 11 through a data cable, thereby establishing a communication connection between the photographing device 10 and the mobile terminal 11. When the first environmental brightness value of the environment is not within the preset brightness threshold range, since the first environmental brightness value is low, the photographing device 10 may determine that the quality of the image captured based on the first environmental brightness value is relatively high. Low, and because the photographing device does not have a light-filling device for the environment, it can send a control instruction to the mobile terminal 11 with the light-filling device, so that the mobile terminal 11 can control According to the instruction, turn on the light supplement device. Further, the mobile terminal 11 can adjust the brightness of the environment in which the photographing device 10 is located based on the brightness adjustment of the light supplement device, so that the adjusted The environmental brightness value is within the preset brightness threshold range, and after the photographing device determines that the adjusted environmental brightness value is within the preset brightness threshold range, image shooting may be performed based on the adjusted environmental brightness value, so that Get high-quality images. Alternatively, the photographing device 10 and the mobile terminal 11 may also establish a communication connection through a wireless connection, as shown in FIG. 1b, the wireless connection may be, for example, Bluetooth connection, wireless connection (Wi-Fi) or proximity Field communication connection, etc.

In one embodiment, the control instructions sent to the mobile terminal by the shooting device are different in different shooting modes. When the shooting device is in the shooting mode or the preview mode, the shooting device moves to the The control instruction sent by the terminal is the first control instruction. As shown in FIG. 1c, when the photographing device is in the photographing mode or preview mode, if the photographing device determines that supplementary light is required based on the first environmental brightness value of the environment in which it is located, The first control instruction is sent to the mobile terminal. After receiving the first control instruction, the mobile terminal controls the light supplement device of the mobile terminal to maintain a constant light state, and the photographing device determines the supplement light After the light device remains in a constant light state, the second environment brightness value of the environment can be detected, and when the second environment brightness value is still not within the preset brightness threshold range, it can be determined that the shooting device is in the second environment brightness value The effect of the image obtained by the next shooting is still unsatisfactory. Therefore, the shooting device may send a brightness adjustment instruction to the mobile terminal, and the mobile terminal may maintain the light supplement device in a constant light state based on the received brightness adjustment instruction. The brightness value of is adjusted until the third environment brightness value of the environment where the photographing device is located is within the preset brightness threshold range.

In one embodiment, when the photographing device is running for image shooting, the method of starting the photographing device in the photographing device includes: starting by the user clicking a physical button; or, by the user clicking on the application displaying the photographing application on the display screen Icon to start. Wherein, the photographing device may be a camera, for example. After the shooting device starts the camera, the light metering device of the shooting device can be called to detect the brightness value of the environment. Further, the shooting device can be based on the brightness value of the environment. The first brightness value is determined by detecting, and it is determined whether supplementary light is needed by judging whether the first brightness value is within a preset brightness threshold range. In some embodiments, the light metering device of the shooting device may be the main shooting lens of the shooting device. Specifically, the main shooting lens may perform preliminary shooting based on current shooting parameters, and then perform brightness statistics on the shooting screen, and then Adjust the shooting parameters of the shooting target or focus area, so as to realize the detection of the brightness value of the environment and obtain the suitable shooting parameters after light metering. In other embodiments, the light metering device of the photographing device may also be a light metering device other than the main shooting lens of the photographing device. Specifically, a light metering device may be separately provided on the photographing device. When the camera is started for shooting, the light metering device can be called to detect the brightness value of the surrounding environment, and generate suitable shooting parameters, which are sent to the shooting device to control subsequent camera shooting. After the mobile terminal receives the brightness adjustment instruction sent by the photographing device, and before the mobile terminal adjusts the brightness of the supplementary light device when the light supplement device is kept on in a constant state based on the brightness adjustment instruction, the The brightness adjustment space remaining after the light supplement device maintains the always-on state, so that the brightness value when the light supplement device is kept in the always-on state can be adjusted based on the brightness adjustment space and the brightness adjustment instruction.

In one embodiment, if the photographing device is in the photographing mode, the control instruction sent by the photographing device to the mobile terminal is the second control instruction, as shown in FIG. 1d, when the photographing device is in the photographing mode If the photographing device determines that flashing light is needed based on the second environmental brightness value of the environment, it sends a second control instruction to the mobile terminal. After receiving the second control instruction, the mobile terminal The light-filling device included in the mobile terminal controls so that the light-filling device performs pre-flashing. While the light-filling device performs pre-flashing, the photographing device can use the light metering device to monitor the environment. Photometry is used to determine the fourth ambient brightness value of the environment where the supplementary light device performs pre-flash. Further, if the photographing device determines that the fourth ambient brightness value of the light supplement device during pre-flashing is still not within the preset brightness threshold range, it determines the flash brightness value required for image shooting, and The flash brightness value is sent to a mobile terminal. After the mobile terminal receives the flash brightness value, if it is determined that the photographing device is performing image shooting, it will flash according to the flash brightness value to ensure that the captured image The quality is higher. Or, if the shooting device determines that the fourth ambient brightness value when the light supplement device performs pre-flashing is within the preset brightness threshold range, if the mobile terminal determines that the shooting device is performing image shooting, it will follow the pre-flash The brightness value is flashed, so as to guarantee the quality of the captured image.

In one embodiment, the mobile terminal controls the light supplement device to perform pre-flashing, and the camera detects the fourth ambient brightness value of the environment at the same time, and the light supplement device of the mobile terminal determines The flash brightness value of the flash and the image shooting of the photographing device also occur at the same time. However, due to the different positions of the flash and the shutter, there is a delay in response. Therefore, the mobile terminal controls the light supplement device to perform pre-flash and the When the photographing device detects that the time difference between the brightness values of the fourth environment is less than or equal to the preset time difference threshold, it can be considered that the pre-flash of the fill light device and the detection of the fourth environment brightness value by the photographing device occur simultaneously; When the time difference between the flash brightness value determined by the light supplement device and the image shooting by the photographing device is less than or equal to the preset time difference threshold, it can also be considered that the light supplement device flashes at the flash brightness value, and The image capturing by the shooting device is performed simultaneously. Wherein, the preset time difference threshold may be, for example, 1 millisecond, or 2 milliseconds.

Please refer to FIG. 2, which is a schematic flowchart of an image shooting method according to an embodiment of the present invention. The image shooting method may be applied to the above-mentioned shooting device. As shown in FIG. 2, the method may include:

S201: Determine that the mobile terminal enters a flash mode or a fill light mode.

In one embodiment, it may be determined that the mobile terminal enters the light supplement mode first, or it is determined that the mobile terminal enters the flash mode; wherein, the light supplement mode is used to make the mobile terminal control the light supplement device to maintain a constant light state, The flash mode is used to enable the mobile terminal to control the light supplement device to flash when the photographing device performs image photographing. The mobile terminal can keep the fill light mode or flash mode always on, and can also turn on the fill light mode or flash mode when a user's turn-on operation is detected, or the mobile terminal can be within a preset time period The fill light mode or flash mode is automatically turned on. Wherein, the preset time period is a default time period in which the first environment brightness value of the environment where the photographing device is located is relatively small, and the preset time period may be, for example, 19:00 to 6:00 of the next day. The hardware or software of the shooting device may have a built-in timer or a world clock. When the built-in time reaches the time period from 19 pm to 6 o'clock the next day, it is considered to be night shooting, and the shooting device starts shooting Trigger the brightness adjustment process at time.

S202: Detect a first environmental brightness value of the environment where the photographing device is located, and determine whether the first environmental brightness value is within a preset brightness threshold range.

After it is determined that the mobile terminal enters the fill light mode or the flash mode, the photographing device can measure the brightness value of the environment based on its own light metering system. The light metering system includes the light metering device described above. The light metering device can perform light metering detection on the environment to determine the first environmental brightness value of the environment.

After the photographing device determines the first environmental brightness value of the environment, it can compare the first environmental brightness value with a preset brightness threshold range, and determine whether the first environmental brightness value is within the preset Brightness threshold range, if it is determined that the first environmental brightness value is not within the preset brightness threshold range, then step S203 is performed, and if it is determined that the first environment brightness value is within the preset brightness threshold range, then it is determined The environment in which the shooting device is located is suitable for image shooting, so that an instruction for the shooting device to perform image shooting can be directly issued. In an embodiment, the preset brightness threshold value range is a brightness value range suitable for image shooting.

S203: If it is determined that the first environmental brightness value is not within the preset brightness threshold range, send a control instruction to the mobile terminal.

In one embodiment, if the photographing device determines that the first environmental brightness value is not within the preset brightness threshold range, it is determined that the photographing device is a photographed image obtained by photographing the image based on the first environmental luminance value The effect is not good. If the photographing device does not have a supplementary light device or the supplementary light device of the photographing device itself does not have a supplementary light effect on the ambient brightness value that does not meet the photographing requirements, then send to the mobile terminal connected to the photographing device A control instruction, so that the mobile terminal responds to the control instruction to perform brightness adjustment processing for the environment in which the photographing device is located, so that the obtained adjusted environment brightness value can be within the preset brightness threshold range.

In one embodiment, the control instruction sent by the shooting device to the mobile terminal is determined based on the shooting mode of the shooting device, so when the shooting device sends the control instruction to the mobile terminal, the The shooting mode of the shooting device, thereby generating the control instruction according to the shooting mode, and sending the generated control instruction to the mobile terminal, wherein the first shooting mode is the first shooting mode or the second shooting mode When the shooting mode is the first shooting mode, the generated control instruction is the first control instruction, and the first control instruction is used to control the light-filling device of the mobile terminal to maintain a constant light state.

After the photographing device controls the light-filling device to maintain a constant light state through the first control instruction, a second environmental brightness value of the environment in which the photographing device is located can be obtained, and the second environmental brightness value is After the light-filling device remains constantly on, the environment where the photographing equipment is located is determined by photometry. Further, after the photographing device determines the second environment brightness value of the environment in which it is located, it can be determined whether the second environment brightness value is within the preset brightness threshold range, and if it is determined that the second environment brightness value is not within the preset brightness threshold range. The preset brightness threshold range indicates that the shooting device still cannot obtain a better shot image even when shooting images under the second environmental brightness value, so the shooting device may send brightness to the mobile terminal An adjustment instruction, so that the mobile terminal responds to the brightness adjustment instruction to adjust the brightness value when the supplementary light device is in the always-on state, until the third environment brightness value of the environment in which the photographing device is located is in the preset state Set the brightness threshold range. In one embodiment, if the second environment brightness value is determined to be within the preset brightness threshold range after the shooting device determines the second environment brightness value of the environment, it means that the shooting device is in the Image shooting under the second environment brightness value can obtain a better image, then the shooting device is directly triggered to shoot the image, and the shooting device may be a camera, for example.

In one embodiment, determining that the second environment brightness value is not within a preset brightness threshold range by the photographing device includes: determining that the second environment brightness value is less than a minimum brightness value in the preset brightness threshold range, or greater than The maximum brightness value of the preset brightness threshold range. Therefore, when the photographing device sends a brightness adjustment instruction to the mobile terminal, so that the mobile terminal adjusts the brightness of the supplementary light device when the light supplement device is in the always-on state based on the brightness adjustment instruction, if it is determined that the The second environmental brightness value is less than the minimum brightness value of the preset brightness threshold range, and may be based on the current constant brightness value when the supplementary light device is currently kept in a constant brightness state, and further, the total brightness of the photographing device may be determined. The brightness value of the environment reaches the desired enhanced brightness value of the minimum brightness value of the preset brightness threshold range, so that the desired enhanced brightness value can be included in the brightness adjustment instruction and sent to the mobile terminal, namely The brightness adjustment instruction sent to the mobile terminal is a brightness enhancement instruction, so that the supplemental light device performs brightness enhancement processing on the current constant brightness of the supplementary light device based on the required enhanced brightness value to obtain the enhanced constant brightness value. Bright brightness value, when the light supplement device maintains the enhanced constant brightness value, the third environment brightness value of the environment where the photographing device is located is within the preset brightness threshold range.

If it is determined that the second environment brightness value is greater than the maximum brightness value in the preset brightness threshold range, it indicates that the second environment brightness value is too bright, so that when the shooting device performs shooting based on the second environment brightness value, it may be The brightness is too bright and causes overexposure. In one embodiment, when the second environment brightness value is greater than the maximum brightness value in the preset brightness threshold range, the photographing device first determines that the brightness value of the environment in which it is located reaches the preset brightness threshold range. The brightness value of the maximum brightness value that needs to be reduced, and the brightness value that needs to be reduced is included in the brightness adjustment instruction and sent to the mobile terminal, that is, the brightness adjustment instruction sent to the mobile terminal is a brightness reduction instruction, and The light supplement device is made to perform brightness reduction processing on the current constant brightness of the light supplement device based on the brightness value that needs to be reduced to obtain the weakened constant brightness value. In one embodiment, the light supplement device remains weakened. At the subsequent constant brightness value, the third environment brightness value of the environment where the photographing device is located is within the preset brightness threshold range.

In one embodiment, when the shooting mode is the second shooting mode, the control command generated according to the second shooting mode is the second control command, and the second control command is used to control the mobile terminal The supplementary light device flashes when the photographing device performs image photographing. When the light supplement device controls the light supplement device to perform pre-flashing through the second control instruction, the fourth ambient brightness value of the environment in which the photographing device is located can be simultaneously acquired, and the fourth ambient brightness value is When the light supplement device is pre-flashed, the environment where the photographing equipment is located is determined by photometry. Further, the photographing device may determine whether the fourth environment brightness value is within the preset brightness threshold range, and if it is determined that the fourth environment brightness value is not within the preset brightness threshold range, then the shooting When the device is shooting based on the fourth environment brightness value, it cannot obtain a better image. Therefore, the flash brightness value required by the shooting device for image shooting can be determined, and the fourth environment brightness value is less than When the minimum brightness value of the preset brightness threshold value range, the determined required flash brightness value is greater than the pre-brightness value when the light supplement device performs pre-flash, if the fourth ambient brightness value is greater than the pre-flash Assuming the maximum brightness value in the brightness threshold range, the determined required flash brightness value is less than the pre-brightness value when the light supplement device performs pre-flash.

After the shooting device determines the flash brightness value required for image shooting, the flash brightness value may be sent to the mobile terminal, so that the mobile terminal flashes based on the flash brightness value until the The fifth environment brightness value of the environment where the photographing device is located is within the preset brightness threshold range. In one embodiment, if the photographing device determines that the fourth ambient brightness value is within the preset brightness threshold range, it sends the pre-brightness value when the light supplement device performs pre-flash to the mobile Terminal, so that the mobile terminal flashes light based on the pre-brightness value when the image capturing device performs image shooting.

In one embodiment, since the light supplement device and the photographing device are installed in different terminal equipment, when the photographing device is performing image shooting, there may be a delay in the flashing of the light supplement device, which results in a time difference between the image shooting and flashing. . In order to avoid too long time difference and affect the effect of flash fill light, while improving the responsiveness of the hardware, the socket connection method can be used, as shown in Figure 1a, so that the delay between the shooting operation of the camera and the flash is maintained In the time range of 1-2 milliseconds or less, it is guaranteed that shooting and flashing are performed at the same time.

In one embodiment, the time difference between the shooting device controlling the light supplement device to perform pre-flashing through the second control instruction and the obtaining the fourth environment brightness value of the environment where the shooting device is located is less than Or equal to the preset time difference threshold, the photographing device may consider that the pre-flashing of the light supplement device and the step of determining the fourth ambient brightness value by the photographing device occur simultaneously, that is, the photographing device acquires the The fourth ambient brightness value of the environment is performed when the light supplement device performs pre-flash. Similarly, when the photographing device performs a flash based on the flash brightness value by the mobile terminal and the photographing device performs image shooting based on the adjusted environmental brightness value, the time difference is less than or equal to the preset time difference threshold, It can also be considered that the flashing by the light supplement device and the image capturing by the photographing device are performed simultaneously. Wherein, the preset time difference threshold may be 1 millisecond or 2 milliseconds.

In an embodiment, the above-mentioned light supplement device may include a flash or the screen of the mobile terminal, etc., and the shooting device may include a pan-tilt camera, a sports camera, etc., and the first shooting mode is a shooting mode or a preview mode, so The second shooting mode is a photographing mode.

S204: Perform image shooting based on the adjusted environmental brightness value.

In one embodiment, after the light supplement device adjusts the brightness of the environment where the photographing device is located, so that the adjusted adjusted environment brightness value is at a preset brightness threshold, image shooting may be performed based on the adjusted environment brightness value.

In the embodiment of the present invention, when the photographing device detects that the first environment brightness value of the environment is not within the preset brightness threshold range, it may send a control instruction to the mobile terminal, so that the mobile terminal is based on the control instruction. The brightness of the environment in which the shooting device is located is adjusted so that the obtained adjusted environment brightness value is within a preset brightness threshold range. Further, the shooting device can perform image shooting based on the adjusted environment brightness value, which can ensure shooting The device shoots in an ideal environment to avoid poorly imaged images when the ambient brightness is low or high, which increases the user's satisfaction with the use of the shooting device.

In order to elaborate on the execution steps on the mobile terminal side when adjusting the environment of the shooting device, please refer to FIG. 3, which is a schematic flowchart of an image shooting method according to another embodiment of the present invention. The image shooting method may Applied to a mobile terminal that establishes a communication connection with the photographing device, as shown in FIG. 3, the method may include:

S301: Determine to enter the fill light mode, or determine to enter the flash mode.

Wherein, the fill light mode is used to control the fill light device to maintain a constant light state, and the flash mode is used to control the fill light device to flash when the photographing device is performing image shooting, and the photographing device determines to enter the fill light mode , Or after the flash mode, step S302 may be executed.

S302: Receive a control instruction.

Therefore, the The control instruction received by the mobile terminal is sent by the photographing device when it is determined that the first environmental brightness value of the environment where the photographing device is located is not within a preset brightness threshold range.

Since the control instructions sent by the shooting device in different shooting modes are different, the mobile terminal receives different control instructions when the shooting device is in different shooting modes. In the shooting mode of the shooting device, In the first shooting mode, the control command received by the mobile terminal is the first control command, and when the shooting mode of the shooting device is the second shooting mode, the control command received by the mobile terminal is the second Control instruction.
