Embodiment 1

[0025] A photographing control method provided by an embodiment of the present invention is introduced in detail.

[0026] refer to figure 1 , which shows a photographing control method in an embodiment of the present invention, which is applied to a mobile terminal with a front camera and a rear sensor, and the method includes:

[0027] Step 101, after receiving an operation instruction for turning on the front camera, turn on the front camera and the rear sensor.

[0028] In this embodiment, a sensor is provided on the back of the mobile terminal. When the user holds the mobile terminal with one hand, the sensor can collect the user's operations, thereby controlling the front camera to take pictures or record videos.

[0029] When the mobile terminal receives an operation instruction from the user to turn on the front camera, it turns on the front camera and turns on the rear sensor at the same time.

[0030] Step 102 , detecting whether the user data collected by the rear...

Embodiment 2

[0038] refer to figure 2 , shows a flow chart of a photographing control method in another embodiment of the present invention. Applied to a mobile terminal with a front camera and a rear sensor, the method includes:

[0039] Step 201, after receiving an operation instruction to turn on the front camera, turn on the front camera and the rear sensor.

[0040] In this embodiment, the rear sensor includes a laser focus sensor. The laser focus sensor emits laser light and receives the reflected light reflected by the laser light and the object.

[0041] Step 202 , detecting whether the distance between the user's finger and the laser focus sensor collected by the laser focus sensor is less than a preset distance.

[0042] In this embodiment, the laser focus sensor collects the distance between the user's finger and the laser focus sensor, and the mobile terminal detects whether the distance is less than the preset distance. If the distance is less than the preset distance, the...

Embodiment 3

[0052] refer to image 3 , shows a flow chart of a photographing control method in another embodiment of the present invention. Applied to a mobile terminal with a front camera and a rear sensor, the method includes:

[0053] Step 301, after receiving an operation instruction for turning on the front camera, turn on the front camera and the rear sensor.

[0054] In this embodiment, the rear sensor includes a heart rate sensor. The working principle of the heart rate sensor is that when the light penetrates the skin tissue and irradiates the photosensitive device in the heart rate sensor, the light is attenuated to a certain extent. Among them, the absorption of light by muscles, bones, veins and other connecting tissues is basically unchanged, but blood is different from muscles and bones. When blood flows in arteries, the absorption of light will change. When converting light into electrical signals, since the absorption of light by arteries varies, while the absorption of...

Abstract

The invention provides a photographing method and device. The method comprises the steps of after an operation instruction for starting a front-mounted camera is received, starting the front-mounted camera and a rear-mounted sensor; detecting whether user data collected by the rear-mounted sensor satisfies a preset condition or not; if the user data satisfies the preset condition, controlling the front-mounted camera to photograph; and when the front-mounted camera photographs, detecting whether the user data collected by the rear-mounted sensor satisfies the preset condition or not, and if the preset condition is not satisfied, finishing photographing. Through application of the embodiment of the invention, the photographing can be carried out by holding a machine through a single hand, a mobile terminal is prevented from shaking when the photographing is carried out, the hand holding is convenient, the mobile terminal is not liable to be sheltered or dropped off, an action is natural, the misoperation can be avoided, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for controlling photographing. Background technique [0002] At present, users will have many scenes where the front camera is used to take photos or record videos. The photo or video buttons of some mobile terminals are screen virtual buttons, power-on buttons, fingerprint buttons, etc., or are operated by language commands. [0003] When the mobile terminal uses the front camera to take pictures or video, it needs to press the virtual button on the screen or the switch button to complete the selfie or video recording of the front camera. When the screen of the mobile terminal is large, it is not easy to press the virtual button on the screen with one hand. Or switch the power button, it is easy to cause the mobile terminal to shake greatly, it is easy to cause inaccurate focus, and the hand will block the screen or the mobile terminal will f...
