Abstract

A camera shooting program control method, the method is applied to terminal equipment, and the method includes obtaining motion parameters collected by at least one motion sensor in response to a situation that the terminal equipment enters a camera shooting program from a screen locking state, and determining a motion state of the terminal equipment according to the motion parameters collected by the at least one motion sensor; obtaining a mistaken touch rate of a display screen of the terminal equipment in response to the motion state of the terminal equipment being a moving state; and exiting the camera shooting program in response to a condition that the mistaken touch rate is greater than a preset first proportion threshold value.

First claim

What is claimed is:

1. A camera shooting program control method, wherein the method is applied to terminal equipment, and comprises:
obtaining motion parameters collected by at least one motion sensor in response to a situation wherein the terminal equipment enters a camera shooting program from a screen locking state, and determining a motion state of the terminal equipment according to the motion parameters collected by the at least one motion sensor;
obtaining a mistaken touch rate of a display screen of the terminal equipment in response to a motion state of the terminal equipment being a moving state, wherein the mistaken touch rate comprises a proportion of a mistaken touch frequency of the display screen to a touch control frequency of the display screen, a touch control condition of a control in a picture of the display screen is a normal touch control, and a touch control condition of an area outside the control in the picture of the display screen is a mistaken touch;
exiting the camera shooting program in response to a condition wherein the mistaken touch rate is greater than a preset first proportion threshold value; and
restoring to the screen locking state, and deleting images and videos collected after the terminal equipment enters the camera shooting program from the screen locking state after exiting the camera shooting program.

2. The camera shooting program control method according to claim 1 , wherein obtaining the motion parameters collected by the at least one motion sensor, and determining the motion state of the terminal equipment according to the motion parameters collected by the at least one motion sensor comprise:
obtaining an angle value of the terminal equipment collected by a gyroscope; and
determining the motion state of the terminal equipment is in a moving state in response to the angle value of the terminal equipment continuously changing in a preset angle range, and an angle value change of the terminal equipment comprises two opposite directions.

3. The camera shooting program control method according to claim 2 , wherein determining the motion state of the terminal equipment is in the moving state in response to the angle value of the terminal equipment continuously changing in the preset angle range, and an angle value change of the terminal equipment comprises two opposite directions comprises:
obtaining an acceleration value of the terminal equipment collected by an acceleration sensor in response to the angle value of the terminal equipment continuously changing in the preset angle range, and an angle value change of the terminal equipment comprises two opposite directions;
determining a horizontal movement speed of the terminal equipment according to the acceleration value; and
determining the motion state of the terminal equipment is in the moving state in response to a situation the horizontal movement speed of the terminal equipment is within a preset speed range.

4. The camera shooting program control method according to claim 3 , further comprising:
performing low-pass filtering on the angle value of the terminal equipment collected by the gyroscope; or,
performing low-pass filtering on the acceleration value of the terminal equipment collected by the acceleration sensor.

5. The camera shooting program control method according to claim 1 , wherein obtaining the mistaken touch rate of the display screen of the terminal equipment comprises:
obtaining the mistaken touch rate of the display screen of the terminal equipment within a preset duration; or,
obtaining the mistaken touch rate of the display screen of the terminal equipment in response to the touch control frequency of the display screen reaching a preset frequency threshold value.

6. The camera shooting program control method according to claim 1 , wherein before exiting the camera shooting program, the method further comprises:
obtaining a pixel value of each pixel of a picture in a viewing frame in the display screen; and
determining a blank screen ratio of the viewing frame according to the pixel value of each pixel of the picture in the viewing frame, wherein the blank screen ratio is a ratio of number of pixels with a pixel value lower than a preset pixel threshold value to number of all pixels;
exiting the camera shooting program comprises:
exiting the camera shooting program in response to the condition the blank screen ratio is greater than a preset second proportion threshold value.

7. The camera shooting program control method according to claim 1 , wherein before exiting the camera shooting program, the method further comprises:
generating a prompt window, wherein the prompt window is used for prompting a user that the camera shooting program is about to be exited; and
maintaining the camera shooting program in response to a situation wherein a cancel instruction is received, wherein the cancel instruction is used for representing a situation wherein the camera shooting program is maintained;
exiting the camera shooting program comprises:
exiting the camera shooting program in response to a determination instruction being received or a duration of generating the prompt window exceeding a preset duration threshold value, wherein the determination instruction is used to characterize determination to exit the camera shooting program.

8. The camera shooting program control method according to claim 1 , wherein after exiting the camera shooting program, the method further comprises:
restoring to the screen locking state, and closing a starting key of a camera shooting program in a screen locking interface.

9. An electronic device, comprising a memory and a processor, wherein the memory is configured to store computer instructions capable of running on the processor, and the processor is configured to:
obtain motion parameters collected by at least one motion sensor in response to terminal equipment entering a camera shooting program from a screen locking state, and determine a motion state of the terminal equipment according to the motion parameters collected by the at least one motion sensor;
obtain a mistaken touch rate of a display screen of the terminal equipment in response to a motion state of the terminal equipment being a moving state, wherein the mistaken touch rate comprises a proportion of a mistaken touch frequency of the display screen to a touch control frequency of the display screen, a touch control condition of a control in a picture of the display screen is a normal touch control, and a touch control condition of an area outside the control in the picture of the display screen is a mistaken touch;
exit the camera shooting program in response to a condition the mistaken touch rate being greater than a preset first proportion threshold value; and
restore to the screen locking state, and delete images and videos collected after the terminal equipment enters the camera shooting program from the screen locking state after exiting the camera shooting program.

10. The electronic device according to claim 9 , wherein the processor is configured to:
obtain an angle value of the terminal equipment collected by a gyroscope; and
determine the motion state of the terminal equipment is in a moving state in response to the angle value of the terminal equipment continuously changing in a preset angle range, and an angle value change of the terminal equipment comprises two opposite directions.

11. The electronic device according to claim 10 , wherein the processor is configured to:
obtain an acceleration value of the terminal equipment collected by an acceleration sensor in response to the angle value of the terminal equipment continuously changing in th
