It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1 is a schematic view of an application scenario according to an embodiment of the present application. The present embodiment is described by taking a motion camera as an example.
The motion camera 100 may include a touch screen 110, a camera 120, a housing 130; the housing 130 of the motion camera 100 is generally a sealed and waterproof casing, and a circuit board, an imaging sensor, a communication component and the like are disposed in the cavity of the housing 130, and a processor chip, a memory and the like (not shown in the figure) are integrated on the circuit board. The processor chip is electrically connected to the imaging sensor, the communication component, the memory, the touch screen 110, the camera 120, and the like. In particular use, a user may send control instructions to the processor chip via various keys on the touch screen 110 and/or the housing 130 for performing a shooting task.
The motion camera 100 is often used in an underwater environment for photographing. Although the housing 130 of the sports camera 100 is waterproof, the touch screen 110 of the sports camera is generally a capacitive touch screen, and when the sports camera is in a water-entering state or a water-exiting state, the touch screen 110 generates an electrical signal similar to a touch operation, thereby causing a false touch operation and affecting the normal operation of the sports camera.
In order to solve the above problem, in the embodiment of the present application, a processor chip of the motion camera 100 is configured to obtain a point coordinate sequence reported by the touch screen 110; then fitting the point coordinate sequence to determine a fitting parameter corresponding to the point coordinate sequence; and when the fitting parameters meet the fitting parameter conditions, inhibiting the point coordinates reported by the touch screen 110. The fitting parameter condition means that the absolute value of the difference between the fitting parameter and the reference value is smaller than a preset threshold value; the reference value is related to the change rule of the point coordinate sequence reported by the touch screen when the touch screen is in the water inlet state or the water outlet state. Therefore, the motion camera in this embodiment can perform suppression processing on points reported by the screen when the screen is detected to be in the water outlet state or the water inlet state, so as to avoid false triggering operation caused when the terminal is in a water area, and provide good user experience.
Fig. 2 is a flowchart of a screen control method according to an embodiment of the present application, and as shown in fig. 2, the method of the present embodiment may include:
s201, acquiring a point coordinate sequence reported by a touch screen.
In this embodiment, the processor obtains a point coordinate sequence reported by the touch screen, where the point coordinate sequence includes: and in a preset time period, the coordinate value sequence of the geometric center position of the contact area of the water and the touch screen. The method of the embodiment is suitable for electronic products with capacitive touch screens, such as mobile phones and motion cameras with waterproof functions. In this embodiment, a moving camera is taken as an example for description.
Specifically, in the process of water entering/exiting of the motion camera, water contacts the capacitive touch screen, and a phenomenon of mistaken touch often occurs. Generally, the contact area between the water and the touch screen is processed by the touch screen into a coordinate point and reported to the main controller, and the coordinate point is usually a coordinate value of the center or gravity of the contact area between the water and the touch screen. The embodiment can utilize the point coordinate information in the water outlet and water inlet processes obtained by the capacitive touch screen technology. Based on the point coordinate information, the change of the area covered by water on the touch screen within a preset time period can be obtained in the time dimension.
In an alternative embodiment, after the point coordinate value sequence is acquired through step S201, the coordinate values in the coordinate value sequence may be subjected to a filtering process.
In this embodiment, the point coordinate sequence obtained by the processor is a sequence of coordinates of a contact center point of the water and the touch screen, and the change of the point coordinate sequence is related to the water inlet/outlet posture of the whole product. Because the application considers the scenes that the water bodies such as sea, river and the like are static or the motion state of the water bodies does not change much, the water inlet/outlet attitude of the whole product machine can be equivalent to the self attitude of the whole product machine, and the motion state only considers the motion state of the whole product machine. At this time, the curve obtained by the change of the point coordinate sequence should be a smooth curve, and some points deviating from the curve can be considered as error points or noise points caused by the motion of the water body. Therefore, the point coordinate sequence can be filtered by adopting a data processing method, namely, the coordinate values of the point coordinate sequence with fluctuation exceeding a first preset range are removed, so that the obtained curve is smoother.
In another optional embodiment, after the point coordinate sequence reported by the touch screen is obtained in step S201, the following determination may be made:
and when the number of the point coordinates is smaller than a preset threshold value, inhibiting the point coordinates reported by the touch screen until the number of the point coordinates is not smaller than the preset threshold value.
In this embodiment, a sufficient number of point coordinates are required for fitting the point coordinate sequence. In the initial stage of obtaining the point coordinate sequence, if the number of the point coordinates is insufficient, whether the whole machine is in a water inlet state or a water outlet state cannot be judged. Therefore, the point coordinates reported by the touch screen are firstly inhibited until the number of the point coordinates is not less than the preset threshold value. In this embodiment, the number of acquired point coordinates is limited, that is, when the number of point coordinates in the acquired point coordinate sequence is smaller than a preset threshold, the point coordinates reported by the touch screen are suppressed, so that the effect of delaying processing can be achieved. The design mode can ensure that enough point coordinates are obtained so as to enable the subsequent fitting operation to be more accurate.
S202, fitting the point coordinate sequence to determine a fitting parameter corresponding to the point coordinate sequence.
In this embodiment, the processor may obtain a change rule of the contact area between the water and the capacitive touch screen by calculating a change rule of the point coordinates. In the implementation process, the point coordinate sequence can be fitted to obtain the fitting parameters of the point coordinate sequence.
Specifically, in the process of entering water, the contact area of the touch screen and water is continuously increased, and point coordinate information is continuously close to the center of the touch screen; in the water outlet process, the contact area of the touch screen and water is continuously reduced, and the point coordinate information continuously moves from the center to the edge of the touch screen. Therefore, fitting analysis can be performed on the point coordinate sequence reported by the touch screen to judge whether the motion camera is in a water outlet state or a water inlet state. It should be noted that, in this embodiment, the fitting parameters obtained after fitting the point coordinate sequence are related to the water inlet/outlet attitude of the whole product.
And S203, when the fitting parameters meet the fitting parameter conditions, inhibiting the point coordinates reported by the touch screen.
In this embodiment, when the fitting parameter satisfies the fitting parameter condition, the point coordinate reported by the touch screen is suppressed, that is, the point coordinate reported by the touch screen is not processed. And when the fitting parameters do not meet the preset fitting parameter conditions, normally processing the point coordinates reported by the touch screen.
For example, the point coordinates reported by the touch screen correspond to the virtual shooting keys on the touch screen, and when the fitting parameters satisfy the fitting parameter conditions, that is, when the touch screen is judged to be in a water inlet state or a water outlet state, the reported coordinate points are not processed, that is, the shooting instructions corresponding to the virtual shooting keys are not generated.
Specifically, in the process of entering water, when the contact area between the touch screen and water reaches a certain condition, for example, when the touch screen completely enters a water area, the touch screen notifies the main control of the large-area inhibition state and stops reporting coordinates, and at this time, the touch screen continuously maintains the large-area inhibition state after entering water. And when the contact area of the touch screen and water does not meet the large-area inhibition state any more, recovering the reported coordinates.
Illustratively, the fitting parameter satisfying the fitting parameter condition includes: the absolute value of the difference between the fitting parameter and the reference value is smaller than a preset threshold value.
Specifically, the contact area changes corresponding to different water inlet postures and different water inlet speeds are different. For example, the point coordinate information of different water entry postures and different water entry speeds can be acquired according to an experimental mode or a simulation mode, then curve fitting is carried out on the point coordinate information of different water entry postures and different water entry speeds to obtain the reference values, and the reference values of different water entry postures and different water entry speeds are stored. And when judging whether the fitting parameters meet the fitting parameter conditions, comparing the fitting parameters obtained in the actual state with the prestored reference values, and if the absolute value of the difference between the fitting parameters in the actual state and the reference values is smaller than a preset threshold value, determining that the fitting parameters meet the fitting parameter conditions. Otherwise, the fitting parameters do not satisfy the fitting parameter conditions.
For example, the processor may further obtain the attitude information and the motion information of the touch screen according to a certain frequency during the motion of the touch screen, perform real-time calculation on the reference value, and when it is determined that the absolute value of the difference between the fitting parameter and the reference value calculated in real time is smaller than a preset threshold, the fitting parameter satisfies the fitting parameter condition. Otherwise, the fitting parameters do not satisfy the fitting parameter conditions.
In this embodiment, a point coordinate sequence reported by a touch screen is obtained; fitting the point coordinate sequence to determine a fitting parameter corresponding to the point coordinate sequence; and when the fitting parameters meet the fitting parameter conditions, inhibiting the point coordinates reported by the touch screen. Therefore, when the screen is detected to be in the water outlet state or the water inlet state, the points reported by the screen can be restrained, the false triggering operation caused when the terminal is in the water area is avoided, and the user experience is good.

Then, the water inlet/outlet attitude of the capacitive touch screen can be calculated through the attitude information of the electronic equipment, and a reference value can be obtained by combining motion information, such as speed information. The reference value is related to a change rule of a point coordinate sequence reported by the touch screen when the touch screen is in a water inlet state or a water outlet state. Optionally, the reference values comprise: an inlet water reference value and an outlet water reference value.

And performing integral operation according to the angular velocity information of the three dimensions to obtain the water outlet or water inlet speed of the touch screen. And finally, determining a first variable quantity sequence of the contact area of the water and the touch screen in a preset time period according to the water outlet angle of the touch screen and the water outlet speed of the touch screen.

And if the absolute value of the difference between the fitting parameter and the water inlet reference value or the water outlet reference value is smaller than a preset threshold value, the fitting parameter meets the fitting parameter condition.
