All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Embodiment 1 of the present invention provides a display switching method, which is specifically described below with reference to the accompanying drawings.
Referring to fig. 2, the figure is a schematic flow chart of a display switching method provided by the present invention. The display switching method specifically comprises the following steps:
s201: when the received first pressing instruction is in a first preset range, determining a preview video corresponding to the first pressing instruction.
As a possible embodiment, the first pressing instruction may be a direct pressing of a finger on the display screen, or an indirect pressing of a cursor on the display screen, where the cursor may be controlled by a mouse, or may be controlled by another method.
As a possible implementation manner, when a first press instruction is received and is within a first preset range, the following technical solutions may be adopted for determining a preview video corresponding to the first press instruction:
receiving a first pressing instruction, and judging whether the first pressing instruction is in a first preset range;
and when the first pressing instruction is in a first preset range, taking a video displayed in the first preset range as a preview video corresponding to the first pressing instruction.
For example, FIG. 3 is a schematic diagram of the coordinates of the main video and the preview video (i.e., video X) on the display screen, as shown in FIG. 3, with the upper left of the touch screenThe angle is the origin of coordinates, the right is the positive direction of the X axis, the downward is the positive direction of the Y axis, a rectangular coordinate system is established, and then the coordinates of four top points of the main area are respectively (X)m1,Ym1)、(Xm2,Ym2)、(Xm3,Ym3)、(Xm4,Ym4). The four vertex coordinates of the video X in the preview area are (X)p1,Yp1)、(Xp2,Yp2)、(Xp3,Yp3)、(Xp4,Yp4). Suppose the coordinates of the first press command are (X, Y), if X ism1<＝X<＝Xm2And Y ism1<＝Y<＝Ym4This indicates that the point is within the main video area. Suppose the coordinates of the first press command are (X, Y), if X isP1<＝X<＝XP2And Y isP1<＝Y<＝YP4If the point is in the range of the video X in the preview area, the video X is the preview video corresponding to the first press instruction.
S202: and receiving a second instruction, and judging whether the second instruction belongs to an equipment control instruction or a video switching instruction.
As a possible implementation manner, the following technical solution may be adopted to determine whether the second instruction belongs to the device control instruction or the video switching instruction: judging whether a first lifting instruction and a first pressing instruction are in the same area or not, wherein the first lifting instruction is an instruction corresponding to the first pressing instruction; when the area where the first lifting instruction and the first pressing instruction are located is different, judging whether the first lifting instruction is in a second preset range; and when the first lifting instruction is in the second preset range, taking the first lifting instruction as the second instruction, and judging that the second instruction belongs to a video switching instruction. In the above embodiment, the second preset range may be understood as the main region. That is, when the first press command is in the preview area and the first lift command is in the main area, that is, when the user's finger presses and drags in the main area in a certain video screen of the preview area, the main screen is switched to the screen of the preview video.
As a further embodiment, the display switching method further includes: when the area where the first lifting instruction and the first pressing instruction are located is the same, judging whether a second pressing instruction is received within a preset time period after the first lifting instruction; when the second pressing instruction is received within a preset time period after the first lifting instruction, the first lifting instruction and the second pressing instruction form the second instruction, and the second instruction is judged to be a video switching instruction; and when the second press instruction is not received within a preset time period after the first lifting instruction, taking the first lifting instruction as the second instruction, and judging that the second instruction is an equipment control instruction. In the above embodiment, it is determined whether the single-click operation or the double-click operation is performed by determining that the second press instruction is not received within a preset time period after the first lift instruction.
When the second press instruction is received within a preset time period after the first lifting instruction, taking the first lifting instruction and the second press instruction as the second instruction, and judging that the second instruction is a video switching instruction; namely, the first pressing instruction, the first lifting instruction and the second pressing instruction form a double-click operation, and when a user finger quickly and continuously clicks a certain video picture in a preview area twice, the main picture video is switched to the picture of the preview video. When the second pressing instruction is not received within a preset time period after the first lifting instruction, taking the first lifting instruction as the second instruction, and judging that the second instruction is an equipment control instruction; namely, the first pressing instruction and the first lifting instruction form clicking operation, when a certain video picture in a preview area is clicked on the touch display screen by a finger of a user, the PTZ camera corresponding to the video is selected, the PTZ camera can be controlled in a functional area, and at the moment, the main picture video is not switched.
In the embodiment of the present invention, the first press command corresponds to a press at the time of a single-click operation or a first press at the time of a double-click operation, and the second press command corresponds to a second press at the time of a double-click operation.
As a possible embodiment, a timer is used to implement the control of the preset time period after the first lift instruction. The activity duration of the timer is the preset time period, namely after the timer is activated and the preset time period passes, the timer is automatically closed. For example: when the first lifting instruction is received, activating a preset timer; when the second pressing instruction is received, if the timer is in an active state, judging that the second pressing instruction is received within a preset time period after the first lifting instruction; when the second pressing instruction is received, the timer is in a closed state, and it is determined that the second pressing instruction is not received within a preset time period after the first lifting instruction.
Further, when the second pressing instruction is received, the timer is in an active state, and the timer is further turned off. Thereby, a closed-loop control of the timer can be accomplished.
S203: when the second instruction belongs to the equipment control instruction, taking the camera equipment corresponding to the preview video as the camera equipment needing to be controlled currently; and when the second instruction belongs to a video switching instruction, switching the preview video into a main video.
As a further embodiment, after the image capturing apparatus corresponding to the preview video is taken as the image capturing apparatus currently needing to be controlled, the method further comprises marking the preview video to be distinguished from other preview videos, so that which image capturing apparatus the currently controlled image capturing apparatus is can be displayed more clearly. The manner of marking may be any manner, for example, the border of the preview screen is changed to a different color from the borders of the other preview screens.
By adopting the technical scheme, the video switching and the pan-tilt control in the recording and playing equipment can be separated, and the two functions can be respectively realized through different operations of a user, so that the pan-tilt corresponding to the main video displayed in the main area can be controlled, the pan-tilt corresponding to the preview video displayed in the preview area can be controlled, the display in the main area is not required to be switched, and the viewing experience is improved.
For example, the display switching method according to embodiment 1 of the present invention may be divided into three parts, namely, a finger-down event process, a finger-up event process, and a timer event process.
As shown in fig. 4, the finger-down event processing includes the following steps:
(a1) if the coordinates of the pressed point are within a certain video area in the preview area and the timer is active (indicating that this is a second press within 500 milliseconds), then step b1 is performed; if the timer is not activated (pressed for the first time), the pressing event processing is finished;
(b1) the timer is closed and the double click variable is marked to inform the system that a double click event has occurred.
As shown in fig. 5, the finger lift event processing includes the steps of:
(a2) if the coordinates of the lifting point are still in a certain video area in the same preview area, executing step b 2; otherwise, performing step c 2;
(b2) if the double-click variable is not marked, starting a 500 millisecond timer; otherwise cancel double click variable mark;
(c2) if the coordinates of the lifting point are in the main area, the user generates a dragging behavior, and the main picture is switched into a video picture corresponding to the video area in the preview area when the user presses down the finger.
The timer event processing comprises the following steps: if the timing time is up (no second click is performed within 500 milliseconds), the color of a frame of a certain video area in the preview area clicked by the finger of the user is changed into yellow, and the system is notified that a click event is generated.
Specifically, when a click event occurs, the currently controlled pan/tilt is switched to a pan/tilt camera corresponding to a certain video clicked by a user; when a double-click event is generated, the main picture is switched to a video picture corresponding to a certain video double-clicked by the user.
According to the display switching method provided by the embodiment of the invention, when a first press instruction is received and is in a first preset range, a preview video corresponding to the first press instruction is determined; receiving a second instruction, and judging whether the second instruction belongs to an equipment control instruction or a video switching instruction; when the second instruction belongs to the equipment control instruction, taking the camera equipment corresponding to the preview video as the camera equipment needing to be controlled currently; and when the second instruction belongs to the video switching instruction, switching the preview video to the main video. That is to say, the control of the camera device is separated from the video switching through the above process, and the two functions are respectively realized through different operations, so that before the preview video is switched to the main video, the camera device corresponding to the preview video is firstly used as the camera device which needs to be currently controlled, the control of the camera device is completed, the camera device is adapted to the display requirement of the main video, then the preview video is switched to the main video, and the problem that when the preview video needs to be switched to the main video, the picture when the pan-tilt camera is rotated is included in the switched main video is solved. Furthermore, as the preview video can be switched to the main video only through double-click operation and dragging operation, the simple single-click operation can not be completed, the problem of abnormal switching of the main video caused by mistakenly touching the preview video in the preview area is solved, and the watching experience is greatly improved.
