[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0048] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The embodiment of the present application provides a processing method, which can be applied to electronic equipment, referring to Figure 1 As shown, the method comprises the following steps:

[0050] Step 101: Obtain sensing information.

[0051] Among them, the sensing information obtained represents that there is an input light spot on the display screen; the sensing information represents the sensing values ​​of multiple sensing units that have changed in the sensing array of the display screen, and the sensing areas corresponding to the multiple sensing units that have changed include a first sensing unit area and a second sensing unit area, the first sensing unit area corresponds one-to-one to the input light spot, and the second sensing unit area is adjacent to the first sensing unit area.

[0052] In the embodiment of the present application, the sensing information may be the sensing values ​​of multiple sensing units in the sensing array of the display screen that are obtained by the electronic device after an input light spot is captured on the display screen of the electronic device. It should be noted that the sensing information may be determined by projecting the input light spot onto the display screen in a real environment, so that the sensing units in the sensing array sense the input light spot and then determine the sensing value; of course, the sensing information may also be obtained by simulating a real light environment through application software, thereby projecting the input light spot onto the display screen in a simulated scene, so that the sensing units in the sensing array of the simulated scene sense the input light spot and then determine the sensing value. In a feasible implementation, the input light spot may be generated by infrared light being projected onto the display screen.

[0053] Among them, the second sensing unit area can be adjacent to one of the top, bottom, left and right sides of the first sensing unit area; or, the second sensing unit area can also be multiple sensing unit areas adjacent to multiple sides of the top, bottom, left and right sides of the first sensing unit area; or, the second sensing unit area can also be multiple sensing unit areas adjacent to each of the top, bottom, left and right sides of the first sensing unit area, that is, the second sensing unit area surrounds the first sensing unit area.

[0054] Step 102: Determine the input position of the input light spot on the display screen based on the sensing information.

[0055] In an embodiment of the present application, the electronic device can analyze the sensing information of the sensing unit area to determine the sizes of the corresponding multiple sensing unit areas, and then determine the input position of the input light spot on the display screen according to the sizes of the multiple sensing unit areas.

[0056] Step 103: Based on the input position, an input focus corresponding to the input light spot is displayed on the display screen.

[0057] After determining the input position of the input light spot on the display screen, the electronic device may display an input focus corresponding to the input light spot at the input position on the display screen; it should be noted that the input focus may be used to indicate which information in the electronic device is to be processed.

[0058] The processing method provided by the embodiment of the present application senses the input light spot on the display screen by means of multiple sensing units including a second sensing unit area and a first sensing unit area corresponding one-to-one to the input light spot, and determines the input focus of the input light spot on the display screen based on the sensing information of the multiple sensing units. There will be no situation where the sensing unit is larger than the size of the light spot, thereby solving the problem of inaccurate alignment between the position of the light spot on the display screen and the actual triggered position in the solution of triggering electronic devices by infrared light in the related art.

[0059] Based on the above embodiments, the embodiments of the present application provide a processing method, referring to Figure 2 As shown, the method comprises the following steps:

[0060] Step 201: The electronic device obtains sensing information of a scattered light spot formed by an input light spot projected onto a sensing array via an optical scattering layer of a display screen.

[0061] The sensing area on the sensing array corresponding to the scattered light spot includes a first sensing unit area and a second sensing unit area.

[0062] It should be noted that, refer to Figure 3 As shown, the input light spot can be generated by projecting infrared light onto the display screen through an emitting device capable of emitting infrared light; in a feasible implementation, the emitting device can be a emitting pen or a remote controller, etc.

[0063] In the embodiment of the present application, the optical scattering layer can enlarge the size of the input light spot projected onto the display screen and form a scattered light spot based on the input light spot, so that more sensing units in the sensing array can sense the input light spot; in this way, it is not necessary to make the photosensitive device small enough, thereby ensuring the accuracy of the input position finally determined. Figure 4 As shown, after a beam of infrared light input to the display screen is scattered by the optical scattering layer, the size of the input light spot increases, forming an infrared light spot with a larger area.

[0064] Step 202: The electronic device obtains first sensing information.

[0065] The first sensing information is obtained by projecting the input light spot onto the sensing array.

[0066] In the embodiment of the present application, the first sensing information may be a sensing value of a sensing unit that changes when an input light spot generated by an emitting device capable of emitting infrared light emitting infrared light to a display screen is projected onto a sensing array.

[0067] Step 203: The electronic device determines an extended area based on the first sensing information, and generates second sensing information of the extended area.

[0068] In the embodiment of the present application, after obtaining the first sensing unit area, the area after the input light spot is diffused can be simulated by application software as the extended area, and then the second sensing information is the sensing value of the sensing unit at the extended area determined based on the first sensing information; it should be noted that in actual applications, the distance between the display screen and the sensing unit can be determined based on the first sensing unit, and the extended area can be determined based on the angle of light scattering and the distance between the display screen and the sensing unit. The extended area is, for example, rectangular, circular, elliptical, etc.; and, for the case of multi-value sensing units, the closer the second sensing unit is to the sensing unit corresponding to the input light spot, the greater the value of the second sensing information corresponding to it determined by simulation.

[0069] For the case of a binary sensing unit, the sensing value at the extended area is binary (0 and 1). If the sensing value is 1, it means that the extended area senses light; if the sensing value is 0, it means that the extended area does not sense light; at this time, the second sensing information can be determined by the sensing unit corresponding to the extended area.

[0070] Step 204: The electronic device uses the first sensing information and the second sensing information as sensing information.

[0071] The first sensing information and the second sensing information may be used together as the sensing information finally obtained, so as to determine the input position of the input light spot on the display screen based on the sensing information.

[0072] It should be noted that steps 205 to 207 may be executed after step 201 or steps 202 to 204.

[0073] Step 205: The electronic device determines the center point of the sensing area represented by the sensing information.

[0074] Among them, the electronic device can analyze the sensing information, determine the size of the first sensing unit area and the second sensing unit area, and then determine the center point of the entire area; it should be noted that the size of the first sensing unit area and the second sensing unit area in the embodiment of the present application is not the physical size of the first sensing unit area and the second sensing unit area, but a size determined based on the size of the sensing information.

[0075] In the embodiment of the present application, step 205 can be implemented in the following manner:

[0076] Step 205a: The electronic device determines the size of the sensing area corresponding to each sensing unit based on the sensing values ​​of the multiple sensing units and the upper limit threshold.

[0077] The sensing value is a plurality of values, the plurality of values ​​are related to the sensed light amount, and the plurality of values ​​have an upper limit threshold.

[0078] In the embodiment of the present application, the size of the sensing area corresponding to the sensing unit can be determined based on the amount of light sensed by the sensing unit and the upper limit threshold corresponding to the sensing value; in a feasible implementation, the upper limit threshold of the sensing value is 128, and the range of multiple values ​​included in the sensing value is 0-128, then the size of the sensing area corresponding to the sensing unit corresponding to different sensing values ​​can be determined based on the pre-set correspondence between the sensing value and the sensing area size, thereby determining the size of the sensing area corresponding to each sensing unit; of course, the size of the sensing value depends on the amount of light sensed by the sensing unit; and, the larger the sensing value, the larger the sensing area size of the corresponding sensing unit.

[0079] In other embodiments of the present application, the sensing value may also be expressed in the form of binary values, that is, the sensing value may include two values ​​0 and 1; if the sensing value is a first value 1, it indicates that the sensing unit senses light; if the sensing value is a second value 0, it indicates that the sensing unit does not sense light; at this time, the size of the sensing area may be determined based on the size of the sensing unit whose sensing value is the first value.

[0080] Step 205b: The electronic device determines the center of the sensing area based on the sizes of the sensing areas of the multiple sensing units.

[0081] The sizes of the sensing areas of the multiple sensing units may be analyzed to determine the center point of the sensing area.

[0082] In the embodiment of the present application, step 205b can be implemented in the following manner:

[0083] The sensing unit with the largest sensing value among the multiple sensing units is determined as the sensing unit where the reference center of the sensing area is located, and the center of the sensing area is determined based on the sizes of the sensing areas of the multiple sensing units and the reference center.

[0084] When determining the center of the sensing area, the sensing unit with the largest sensing value can be first determined from multiple sensing units as the sensing unit corresponding to the reference center, that is, the reference center is in the sensing unit with the largest sensing value; then, the center of the sensing area can be determined from multiple sensing units based on the sensing area size of each sensing unit and the reference center. In other words, the candidate center position can be determined based on the sensing area size, and the candidate center position closest to the reference center can be determined from the candidate center positions as the center of the sensing area.

[0085] Step 206: The electronic device uses the center point as the input position of the input light spot.

[0086] The input position overlaps with the position of the input light spot on the display screen; that is, the position of the input light spot on the display screen is the position corresponding to the center point on the display screen, and the input position on the display screen is also the position corresponding to the center point on the display screen.

[0087] or;

[0088] The input position is closer to the position of the input light spot on the display screen relative to the sensing position of the input light spot in the first sensing unit area; that is, the first difference between the input position and the position of the input light spot on the display screen is smaller than the second difference between the sensing position of the input light spot in the first sensing unit area and the position of the input light spot on the display screen, that is, the first difference is smaller than the second difference, thereby making the input position closer to the position of the input light spot.

[0089] Step 207: The electronic device controls the display of an input focus corresponding to the input light spot on the display screen based on the input position.

[0090] In other embodiments of the present application, when the emitting device does not emit infrared light perpendicular to the display screen, the electronic device determines the receiving angle of the input light spot received by the display screen based on the gravity sensor, and then determines the offset of the input light spot on the layer where the sensing array is located based on the distance between the display screen and the layer where the sensing array is located and the receiving angle, and corrects the input position based on the offset.

[0091] The processing method provided by the embodiment of the present application senses the input light spot on the display screen by means of multiple sensing units including a second sensing unit area and a first sensing unit area corresponding one-to-one to the input light spot, and determines the input focus of the input light spot on the display screen based on the sensing information of the multiple sensing units. There will be no situation where the sensing unit is larger than the size of the light spot, thereby solving the problem of inaccurate alignment between the position of the light spot on the display screen and the actual triggered position in the solution of triggering electronic devices by infrared light in the related art.
