The second light sensation value is different from the first light sensation value. The second time is after the first time. The first light sensation value is the intensity of the external environment light at the first moment. The second light sensation value is the intensity of the external environment light at the second moment. The second distance value refers to a distance from an external object to the terminal. The second distance value is different from the first distance value.

Step S433: and judging whether the second light sensation value meets a second preset light sensation threshold value or not.
The second preset light sensation threshold refers to a preset light sensation value interval, and the second preset light sensation threshold is smaller than the first preset light sensation threshold. Namely, the maximum value of the second preset light sensation threshold is smaller than the minimum value of the first preset light sensation threshold. For example, the first predetermined light sensation threshold value is 480 lux to 520 lux, and the second predetermined light sensation threshold value is 300 lux to 400 lux. And comparing the second light sensation value with a value in a preset light sensation value interval to judge whether the second light sensation value meets the second preset light sensation threshold value. When the second light sensation value is within the preset light sensation value interval, the second light sensation value meets a second preset light sensation threshold value; when the second light sensation value is not within the preset light sensation value interval, the second light sensation value does not meet a second preset light sensation threshold value.
Step S434: and if so, judging whether the second distance value meets a preset distance threshold value.
If the second light sensation value meets the second preset light sensation threshold value, it indicates that the intensity of the external light acquired by the terminal is weakened, and at this time, the intensity of the external light may be weakened, or the terminal may be shielded by an external object.

Step S436: and if the second distance value does not meet the preset distance threshold value, sending a first switching instruction, wherein the first switching instruction is used for indicating that the first camera is closed and the second camera is started.
If the second distance value does not meet the preset distance threshold value, it is indicated that the distance from the external object to the terminal is far, and the external object does not shield the camera of the terminal. And if the second light sensation value meets the second preset light sensation threshold value, the intensity of the external light is weakened. And sending a first switching instruction, wherein the first switching instruction is used for indicating the first camera to be closed and the second camera to be started. The second camera is suitable for being used in a scene with weak intensity of external environment light. Such as at night, etc. The second camera includes a second imaging sensor and a second aperture. The pixels of the second imaging sensor are lower and the pixels of the second imaging sensor are lower than the pixels of the first imaging sensor; the aperture value of the second aperture is smaller than that of the first aperture. The second aperture value is small, the intensity of external environment light entering the second camera is improved, lighting of the second camera is facilitated, and therefore the brightness of pictures shot by the terminal is improved.
In this embodiment, the intensity of the external environment light of the terminal is stronger, the first camera is started at this time, and the aperture value of the first camera is larger, so that the intensity of light entering the first camera by the external environment light is reduced, and the brightness of a shot picture of the first camera is prevented from being too high. When the terminal is shielded by an external object, the terminal sends a prompt signal, and the situation that the terminal is still switched to the camera when the terminal is shielded by the external object is avoided. When the intensity of the external environment light is weakened to cause the brightness of the shot picture to be lower, the first camera is closed, the second camera is started to shoot, and the second camera is suitable for being used in a scene with weaker intensity of the external environment light, so that the brightness of the shot picture of the terminal is improved, and the terminal can accurately start the corresponding camera according to the intensity of the external environment light.
Referring to fig. 5, fig. 5 is a flowchart of a terminal control method according to another embodiment of the present application.

In this embodiment, the second camera is suitable for being used in a scene with weak intensity of external environment light, so that the brightness of a picture shot by the terminal is improved, and the terminal can accurately start a shooting mode corresponding to the intensity of the external environment light.
Referring to fig. 6, fig. 6 is a flowchart of a terminal control method according to another embodiment of the present application. The terminal control method according to the present embodiment is basically the same as the terminal control method described in the description of fig. 5 and 5, except that step S440 includes step S442, step S443, step S444, step S445, and step S446, and steps S542 to S546 are specifically described below.
Step S442: and acquiring a third light sensitivity value and a third distance value.
The light sensation values further comprise a third light sensation value, and the third light sensation value is obtained to obtain the intensity of the external environment light, wherein the third light sensation value refers to the intensity value of the external environment light. The third light sensation value is different from the first light sensation value. The third light sensation value is the intensity of the external environment light at a third moment, and the third moment is after the first moment.
Step S443: and judging whether the third light sensation value meets a third preset light sensation threshold value or not.
The first preset light sensation threshold refers to a preset light sensation value interval. And the third preset light sensation threshold is greater than the first preset light sensation threshold. That is, the minimum value of the third preset light sensation threshold is greater than the maximum value of the first preset light sensation threshold. For example, the third predetermined light sensation threshold is 600 lux to 700 lux, and the first predetermined light sensation threshold is 480 lux to 520 lux. And comparing the third light sensation value with a numerical value in a preset light sensation value interval to judge whether the third light sensation value meets the third preset light sensation threshold value or not. When the third light sensation value is within the preset light sensation value interval, the third light sensation value meets a third preset light sensation threshold value; and when the third light sensation value is not in the preset light sensation value interval, the third light sensation value does not meet a third preset light sensation threshold value.
Step S444: and if so, judging whether the third distance value meets a preset distance threshold value.
And if the third light sensation value meets the third preset light sensation threshold value, the intensity of the external light acquired by the terminal on the surface is enhanced. In this case, the intensity of the external light may be increased, or the terminal may be shielded by an object emitting light from the outside. For example, the terminal may move from a room with weak light to an outdoor with strong light when shooting, or may be shielded by an external light. And judging whether the third distance value meets a preset distance threshold value so as to confirm whether the terminal is shielded.
In another embodiment, if the third light sensation value does not satisfy a third preset light sensation threshold, the second camera is indicated to keep running. The second camera is in an operating state, and can acquire an external picture. And after the second camera receives a shooting instruction, shooting by the second camera, wherein the shooting instruction is not limited to touch screen operation, sound and the like of a user.

And if the third distance value meets a preset distance threshold value, indicating that an external object is close to the terminal and the external object shields the camera of the terminal. And sending a prompt signal to prompt the user that the terminal is shielded.
Step S446: and if the third distance value does not meet the preset distance threshold value, sending a second switching instruction, wherein the second switching instruction is used for indicating that the second camera is closed and the first camera is started.
If the third distance value does not meet the preset distance threshold value, it is indicated that the distance between the external object and the terminal is short and far, and the external object does not shield the camera of the terminal. And the third light sensation value is greater than the third preset light sensation threshold value, and the third preset light sensation threshold value is greater than the first preset light sensation threshold value, indicating that the intensity of the external light is enhanced. At this time, if the second camera is still used, the brightness of the shot picture is too high. And sending a second switching instruction, wherein the second switching instruction is used for indicating the second camera to be closed and the first camera to be started. The aperture value of the first camera is large, the light intensity of external environment light entering the first camera is reduced, the overhigh brightness of a shot picture is avoided, and the shooting effect of the terminal is improved.
In an embodiment, if the third light sensation value is greater than the third preset light sensation threshold value, a third switching instruction is sent, where the third switching instruction is used to switch the second camera to the first camera. The third light sensation value is larger than the third preset light sensation threshold value, so that the intensity of the external light sensation is enhanced, a third switching instruction is sent at the moment, the first camera is started to shoot, the light intensity of the external environment light entering the first camera is reduced, the phenomenon that the brightness of a shot picture is too high is avoided, and the shooting effect of the terminal is improved. Further, the steps of obtaining a third distance value and comparing the third distance value with the preset distance threshold value are reduced, and the efficiency of the terminal in closing the second camera and starting the first camera is improved.

The second light sensation value is the intensity of the external environment light at the second moment. The second distance value refers to a distance from an external object to the terminal. The second distance value is different from the first distance value. The first distance value is the distance from an external object to the terminal at a first moment; and the second distance value is the distance from an external object to the terminal at the second moment. It is understood that the light sensor 560 transmits the collected second light sensation value to the memory 570, so that the memory 570 stores the second light sensation value.

The second preset light sensation threshold refers to a preset light sensation value interval, and the second preset light sensation threshold is smaller than the first preset light sensation threshold. Namely, the maximum value of the second preset light sensation threshold is smaller than the minimum value of the first preset light sensation threshold. For example, the first predetermined light sensation threshold value is 480 lux to 520 lux, and the second predetermined light sensation threshold value is 300 lux to 400 lux. The determining unit 502 compares the second light sensation value with a value in a preset light sensation value interval to determine whether the second light sensation value satisfies the second preset light sensation threshold. When the second light sensation value is within the preset light sensation value interval, the second light sensation value meets a second preset light sensation threshold value; and when the second light sensation value does not meet a second preset light sensation threshold value, indicating that the first camera keeps a running state. The first camera keeping the running state means that the first camera is in the running state and can acquire an external picture. After the first camera receives a shooting instruction, the first camera shoots, and the shooting instruction is not limited to touch screen operation, sound and the like of a user. As can be appreciated, the obtaining unit 501 obtains the second preset light sensation threshold from the memory 570.

The processing unit 504 is further configured to issue a first switching instruction when the second distance value does not satisfy a preset distance threshold, where the first switching instruction is used to instruct the first camera 511 to be turned off and the second camera 512 to be turned on.
If the second distance value does not meet the preset distance threshold, it indicates that the distance from the external object to the terminal is relatively long, and the external object does not block the camera 510 of the terminal. And if the second light sensation value meets the second preset light sensation threshold value, the intensity of the external light is weakened. The processing unit 504 sends a first switching instruction, where the first switching instruction is used to instruct the first camera 511 to turn off and the second camera 512 to turn on. Wherein the second camera 512 is suitable for being used in a scene with weak intensity of external ambient light. Such as at night, etc. The second camera 512 includes a second imaging sensor and a second aperture. The pixels of the second imaging sensor are lower and the pixels of the second imaging sensor are lower than the pixels of the first imaging sensor; the aperture value of the second aperture is smaller than that of the first aperture. The second aperture value is small, so that the intensity of external environment light entering the second camera 512 is improved, the lighting of the second camera 512 is facilitated, and the brightness of a picture shot by the terminal is improved.
In this embodiment, the intensity of the external environment light of the terminal is strong, and at this time, the first camera 511 is started, and the aperture value of the first camera 511 is large, so that the intensity of the light entering the first camera 511 by the external environment light is reduced, and the brightness of the shot picture of the first camera 511 is prevented from being too high. When the terminal is shielded by an external object, the prompting unit 503 sends a prompting signal, so that the terminal still starts the second camera 512 when the terminal is shielded by the external object. When the intensity of the external environment light is weakened to cause the brightness of the shot picture to be low, the first camera 511 is closed, the second camera 512 is started to shoot, and the second camera 512 is suitable for being used in a scene with weak intensity of the external environment light, so that the brightness of the shot picture of the terminal is improved, and the terminal can start the corresponding camera 510 accurately according to the intensity of the external environment light.
Further, the processing unit 504 is further configured to issue a second shooting instruction, where the second shooting instruction is used to instruct the second camera 512 to start.
Wherein the second camera 512 is suitable for being used in a scene with weak intensity of external ambient light.

The third light sensation value is different from the first light sensation value. The third light sensation value is the intensity of the external environment light at a third moment, and the third moment is after the first moment.
The determining unit 502 is further configured to determine whether the third light sensation value satisfies a third predetermined light sensation threshold.
The first preset light sensation threshold refers to a preset light sensation value interval. And the third preset light sensation threshold is greater than the first preset light sensation threshold. That is, the minimum value of the third preset light sensation threshold is greater than the maximum value of the first preset light sensation threshold. For example, the third predetermined light sensation threshold is 600 lux to 700 lux, and the first predetermined light sensation threshold is 480 lux to 520 lux. The determining unit 502 compares the first third light sensation value with a value in a preset light sensation value interval to determine whether the third light sensation value satisfies the third preset light sensation threshold. When the third light sensation value is within the preset light sensation value interval, the third light sensation value meets a third preset light sensation threshold value; and if the third light sensation value does not meet a third preset light sensation threshold value, indicating that the second camera keeps a running state. The second camera is in an operating state, and can acquire an external picture. And after the second camera receives a shooting instruction, shooting by the second camera, wherein the shooting instruction is not limited to touch screen operation, sound and the like of a user.
The determining unit 502 is further configured to determine whether the third distance value meets a preset distance threshold when the third light sensation value meets the third preset light sensation threshold.
And if the third light sensation value meets the third preset light sensation threshold value, the intensity of the external light acquired by the terminal on the surface is enhanced. In this case, the intensity of the external light may be increased, or the terminal may be shielded by an object emitting light from the outside. For example, the terminal may move from a room with weak light to an outdoor with strong light when shooting, or may be shielded by an external light. At this time, the determining unit 502 determines whether the third distance value satisfies a preset distance threshold, so as to determine whether the terminal is blocked. In another embodiment, if not, the second camera 512 keeps operating.
The prompting unit 503 is further configured to send a prompting signal when the third distance value meets a preset distance threshold.
If the third distance value meets the preset distance threshold, it indicates that the external object is close to the terminal, and the external object blocks the camera 510 of the terminal. At this time, the prompting unit 503 sends a prompting signal to prompt the user that the terminal is blocked.
The processing unit 504 is further configured to issue a second switching instruction when the third distance value does not satisfy the preset distance threshold, where the second switching instruction is used to instruct the second camera 512 to close and the first camera 511 to start.
If the third distance value does not satisfy the preset distance threshold, it indicates that the distance between the external object and the terminal is short and far, and the external object does not block the camera 510 of the terminal. And the third light sensation value is greater than the third preset light sensation threshold value, and the third preset light sensation threshold value is greater than the first preset light sensation threshold value, indicating that the intensity of the external light is enhanced. At this time, if the second camera 512 is still used, the brightness of the shot picture is too high. The processing unit 504 sends a second switching instruction, where the second switching instruction is used to instruct the second camera 512 to turn off and the first camera 511 to turn on. The aperture value of the first camera 511 is large, so that the light intensity of external environment light entering the first camera 511 is reduced, the excessively high brightness of a shot picture is avoided, and the shooting effect of the terminal is improved.
In one embodiment, if the third light sensation value is greater than the third preset light sensation threshold, the processing unit 504 sends a third switching instruction, and the third switching instruction is used for switching the second camera 512 to the first camera 511. Since the third light sensation value is greater than the third preset light sensation threshold value, the intensity of the external light sensation is enhanced, and at the moment, a third switching instruction is sent to start the first camera 511 to shoot, so that the intensity of light entering the first camera 511 by external environment light is reduced, the phenomenon that the brightness of a shot picture is too high is avoided, and the shooting effect of the terminal is improved. Further, the steps of obtaining a third distance value and comparing the third distance value with the preset distance threshold value are reduced, and the efficiency of the terminal in closing the second camera 512 and starting the first camera 511 is improved.
