Detailed ways

The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

The method flow chart of the present invention is shown in Figure 1, a kind of photographing method of terminal equipment, comprises the following steps:

a. Set the proximity sensing value threshold of the proximity sensor. The proximity sensor can detect the energy level of the infrared light emitted by the infrared LED of the terminal device and reflected back from the outside to judge whether the object is approaching or leaving. The proximity sensing value described in step a is the energy of the reflected infrared light received by the receiver, and the proximity sensing value threshold value is the preset camera threshold value of the system, which is a fixed value. If it is greater than the threshold value, it is determined to be close to the shooting interface. If it is less than the threshold, it is judged as leaving the shooting interface.

b. The mobile phone enters the shooting interface and activates the proximity sensor. The proximity sensor used in the present invention is a general term for sensors that replace contact detection methods such as limit switches and detect without touching the detection object. The movement information and presence information of the detected object can be converted into electrical signals. Among the detection methods replaced by electrical signals, there are methods that use electromagnetic induction to generate eddy currents generated in the metal object of the detection object, methods that use the capacity change of electrical signals caused by the approach of the object to be detected, and methods that use lithium stones and guide switches. . Step b specifically includes: Step 101. Turn on the camera button of the mobile phone; Step 102. After the system obtains the operation command, it sends an opening command to the proximity sensor; Step 103. The proximity sensor starts automatically.

c. Acquire real-time proximity sensing values; Step c specifically includes: Step 201. The built-in infrared LED lamp of the terminal device emits infrared light; Step 202. The receiver receives the energy of the reflected infrared light; Step 203. Generates proximity sensing values . The proximity sensor can detect the energy level of the infrared light emitted by the infrared LED of the mobile phone and reflected back by the outside world, and judge the approach or departure of the object through the energy level.

d. Compare the real-time proximity sensing value with the threshold value, if it is greater than the threshold value, take a picture, and if it is less than the threshold value, return to step c. The comparing the real-time proximity sensing value with the threshold in step d further includes comparing the real-time proximity sensing value with the threshold at least once. For example, when the real-time value of the proximity sensing value obtained once is greater than the threshold value, prepare to take pictures, and obtain the real-time value again before shooting. If it is still greater than the threshold value, it is considered that the object is close to stable and the photo is taken, which avoids misoperation and improves In order to ensure the accuracy of taking photos, of course, the interval between two acquisitions of real-time values is very short, which is the interval of milliseconds.
