Example two
Referring to fig. 2, a flowchart illustrating steps of a prompting method according to a second embodiment of the present invention is shown.
In the embodiment of the present invention, the example in which the prompting method is applied to the video call process is described. The prompting method of the embodiment of the invention comprises the following steps:
step 201: and receiving an object selection instruction sent by opposite-end equipment in the video call process.
The prompting method provided by the embodiment of the invention is applied to the mobile terminal comprising the lifting camera, and the two sides of the lifting camera are respectively provided with the indicating lamps. When the mobile terminal carries out video call with opposite terminal equipment, a target object to be tracked is determined firstly. Specifically, the target object may be selected by a user at the mobile terminal side or selected by a user at the opposite terminal device side. The user at the opposite terminal equipment side selects the target object, and the requirement of the user at the opposite terminal equipment side can be accurately positioned.
And after the video call is started, the opposite terminal equipment performs image recognition on the video picture by using an image processing algorithm, recognizes each object and performs contour marking on the recognized object. The user at the opposite terminal equipment side can select a certain object as a target object to be tracked, the opposite terminal equipment generates an object selection instruction according to the target object information, and sends the object selection instruction to the mobile terminal. The object selection instruction carries target object information.

Step 203: and detecting whether the integrity of the first contour displayed in the picture is greater than a first preset value in real time.
The picture in the embodiment of the invention is acquired by the lifting camera to be a video picture.
In a specific implementation process, the first preset value may be set by a person skilled in the art according to actual requirements, for example: set to one hundred percent, ninety percent, eighty percent, etc., which are not particularly limited in embodiments of the present invention.
Step 204: if not, determining that the first contour does not meet the preset condition.
If yes, determining that the first contour meets the preset condition, returning to step 203 to continuously detect whether the integrity of the first contour displayed in the picture is greater than a first preset value in real time.
Step 203 to step 204 are a manner of determining whether the first contour of the target object displayed in the screen satisfies the preset condition in real time, and another preferable determination manner is: detecting whether a first contour displayed in a picture contains a preset part of a target object in real time; if not, determining that the first contour does not meet the preset condition.
The preset part is a core part of the target object, for example: if the target object is a person, the core part is the face or upper body of the person.
Step 205: and under the condition that the preset condition is not met, at least one of the indicator lamps is turned on to prompt the adjustment target object to display the outline in the picture.
When the first contour of the target object displayed in the picture does not meet the preset condition, the target object is shown to be out of the mirror or partially out of the mirror, the mirror-out direction needs to be determined, and the indicator light in the corresponding direction is turned on according to the mirror-out direction.
In the concrete realization process, if two indicator lamps are respectively arranged on two sides of the lifting camera, when the indicator lamps in the corresponding directions are turned on, only one indicator lamp can be turned on when the indicator lamp on the corresponding side is turned on, and the two indicator lamps on the side can also be turned on.
Step 206: and when the second outline displayed by the target object in the picture is monitored to meet the preset condition, turning off the turned-on indicator lamp.
After the user finds that the indicating lamp is turned on, the moving direction of the camera can be determined according to the position of the turned-on indicating lamp on the lifting camera, the turning-on indicating lamp is turned off when the displayed second contour meets the preset condition along with the change of the display contour of the camera moving target object in the video picture, and the user can stop moving the camera after the turning-off indicating lamp.
The prompting method provided by the embodiment of the invention determines whether a first contour of a target object to be tracked, which is displayed in a video picture, meets a preset condition in real time; under the condition that the preset condition is not met, at least one of the indicating lamps is started to prompt the adjustment of the outline displayed by the target object in the picture, and the adjustment of the angle of the camera by the mobile terminal handheld can be prompted along with the movement of the target object in time in the video call process, so that the display effect of the video picture of the target object in the opposite terminal equipment is ensured, and the video call experience of a user is improved.
EXAMPLE III

Step 303: and under the condition that the preset condition is not met, at least one of the indicator lamps is turned on to prompt the adjustment target object to display the outline in the picture.
When the first outline does not meet the preset condition, the direction of the camera needs to be adjusted for the self-timer shooting, so that the display outline of the user in the preview picture can meet the preset condition.
Specifically, the direction of the self-photographing mirror-out at this time can be determined according to the position of the first profile in the preview interface, and the lifting type camera is lifted to turn on the indicating lamp on the corresponding side so as to prompt a user to adjust the direction of the rear camera.
Step 304: and when the second outline displayed by the target object in the picture is monitored to meet the preset condition, turning off the turned-on indicator lamp.
When the indicating lamp is started, the camera needs to be adjusted to the corresponding direction, and after the indicating lamp is turned off, the camera does not need to be adjusted to the direction any more.
Certainly, the camera is not limited to the above, the camera can be adjusted to the corresponding direction through the red indicator light, and the camera is adjusted to the proper position through the green indicator light without being adjusted. The camera can be adjusted to the corresponding direction through the green indicating light, and the camera is adjusted to the proper position through the red indicating light without being adjusted. The camera can be adjusted to the corresponding direction through red indicator light, and the camera is not required to be adjusted again when the indicator light is turned off to indicate that the camera is adjusted in place. The embodiment of the invention does not specifically limit the specific rule for indicating and adjusting the camera through the indicator lamp.
The prompting method provided by the embodiment of the invention determines whether a first contour displayed by a target object to be tracked in a preview picture meets a preset condition in real time; under the condition that the preset condition is not met, at least one of the indicating lamps is turned on to prompt the adjustment of the outline displayed by the target object in the preview picture, and the angle of the camera can be timely adjusted along with the movement of the target object to prompt a self-timer to adjust the angle of the camera, so that the display effect of the target object in the image to be shot is ensured, the probability of obtaining a satisfactory image by self-shooting is improved, and the self-shooting experience of a user is improved.
