detailed description

The technical solution in this application will be described below in conjunction with the accompanying drawings.

Therefore, the present application provides a detection method in order to achieve the purpose of protecting the telescopic mechanism of the electronic device.

The electronic device in the embodiments of the present application may be various devices with telescopic cameras. For example, the electronic device may be a mobile phone, a bracelet, a display, a tablet computer, a watch, a wearable device, a portable computer, and the like.

In the following, taking the front camera in the mobile phone as a retractable camera as an example, the detection method 200 provided in the present application will be described in detail with reference to FIGS. 1 to 8.

FIG. 1 is a schematic flowchart of a detection method 200 provided in the present application. Hereinafter, each step of the method 200 will be described in detail.

In S210, the camera is controlled to obtain a target image.

In S220, it is determined whether the camera is in an abnormal state of expansion and contraction according to whether the target image includes a shadow area. The abnormal expansion and contraction includes any one of obstructed extension, obstructed retraction, and external force pressing.

In S230, if the camera is in an abnormal state of expansion and contraction, the camera is controlled to perform a target action, and the target action causes the camera to recover from the abnormal state of expansion and contraction.

Specifically, when it is necessary to detect whether the front camera of the mobile phone (hereinafter referred to as the "camera") has an abnormal expansion or contraction, the camera can be controlled to take a picture, so as to obtain the current image (ie, an example of the target image).

According to whether the current image includes a shadow area, it can be determined whether the camera is in an abnormal state of expansion and contraction, and then the camera is controlled to perform a corresponding action (that is, an example of a target action), so that the camera can recover from the abnormal state.

When the target image includes both a shadow area and a non-shadow area (that is, an image captured by the unobstructed part of the camera), the direction along which the boundary line of the shadow area and the non-shadow area is perpendicular to the traveling direction of the camera. The following takes several cases as examples to illustrate the distribution of the shadow area and the non-shadow area in the target image when the target image includes both a shadow area and a non-shadow area.

Situation #1

When the camera is configured on the upper edge of the mobile phone, the direction of travel when the camera is extended or retracted is perpendicular to the upper edge of the mobile phone. At this time, the distribution of the shadow area and the non-shadow area in the target image is shown in Figure 2. It can be seen that the direction along which the boundary between the shaded area and the non-shaded area is perpendicular to the traveling direction of the camera.

Situation #2

When the camera is configured on the lower edge of the mobile phone, the direction of travel when the camera is extended or retracted is perpendicular to the lower edge of the mobile phone. At this time, the distribution of the shadow area and the non-shadow area in the target image is shown in Figure 3. It can be seen that the direction along which the boundary between the shaded area and the non-shaded area is perpendicular to the traveling direction of the camera.

Situation #3

When the camera is configured on the left edge of the mobile phone, the direction of travel when the camera is extended or retracted is perpendicular to the left edge of the mobile phone. At this time, the distribution of the shadow area and the non-shadow area in the target image is shown in Figure 4. It can be seen that the direction along which the boundary between the shaded area and the non-shaded area is perpendicular to the traveling direction of the camera.

Situation #4

When the camera is configured on the right edge of the mobile phone, the direction of travel when the camera is extended or retracted is perpendicular to the right edge of the mobile phone. At this time, the distribution of the shadow area and the non-shadow area in the target image is shown in Figure 5. It can be seen that the direction along which the boundary between the shaded area and the non-shaded area is perpendicular to the traveling direction of the camera.

It should be noted that the positions of the cameras in FIGS. 2 to 5 are merely examples for illustrating the situation, and do not strictly correspond to the distribution of shadow areas and non-shadow areas in the target image.

The following describes in detail the detection methods proposed in this application for the three abnormal expansion and contraction states: obstructed extension, obstructed retraction, and external force pressing.

Situation #1 Restricted to reach out

FIG. 6 shows a schematic flow chart of the detection method 300 corresponding to the hindered extension. Hereinafter, each step of the method 300 will be described in detail.

In S310, when detecting whether the camera is blocked, the control device in the mobile phone (for example, the central processing unit (CPU)) issues an extension instruction to the telescopic mechanism in the mobile phone, and then the extension mechanism executes the extension instruction. Command and drive the camera to extend.

In S320, when the camera starts to extend, the CPU can control the camera to take a picture, and obtain the current image #1 (that is, an example of the first target image).

In S330, the CPU can determine whether the current image #1 has no shadow area at all: if the current image #1 has no shadow area at all, it can be determined that the camera has been fully extended and execute S340; or, if the current image #1 has a shadow area, It can be determined that the camera is blocked from being extended. At this time, S360 can be executed. In addition, in order to further improve the accuracy of detection, S350 can also be executed.

In S340, the detection ends.

In S350, when it is determined that the camera may be blocked from extending, it can be further determined whether the length of time between the camera extending from the beginning to the current moment (i.e., an example of travel time) is greater than or equal to the preset threshold #1 (i.e., An example of the first threshold): If the travel time is greater than or equal to the threshold #1 (for example, 1.2 seconds (s)), it can be determined that the camera extension is blocked. At this time, S360 can be executed; or, if the travel time is less than the threshold #1 At this time, you can return to S320 and continue execution from S320.

In S360, the CPU controls the camera to perform a retracting action.

It should be noted that, in the method 300, S320 can be replaced with: when the travel time after the camera is extended is equal to or greater than the threshold #1, the CPU controls the camera to take a picture and obtains the current image #1. At this time, the method 300 may not include S350, that is, if it is determined in S330 that the current image #1 has a shadow area, it may be determined that the camera is blocked from extending, and S360 is directly executed.

Situation #2 Retraction blocked

FIG. 7 shows a schematic flow chart of the detection method 400 corresponding to the obstruction of retraction. Hereinafter, each step of the method 400 will be described in detail.

In S410, when detecting whether the camera is blocked from being retracted, the CPU issues a retracting instruction to the telescopic mechanism in the mobile phone, and then the extending mechanism executes the instruction and drives the camera to retract.

In S420, when the camera starts to retract, the CPU may control the camera to take a picture, and obtain the current image #2 (ie, an example of the second target image).

In S430, the CPU can determine whether the current image #2 is completely covered by the shadow area: if the current image #2 is completely covered by the shadow area, it can be determined that the camera has been completely retracted and execute S440; or, if the current image #2 is not completely covered If it is covered by the shaded area, it can be determined that the camera is blocked from retraction. At this time, S460 can be executed. In addition, in order to further improve the accuracy of detection, S450 can also be performed.

In S440, the detection ends.

In S450, when it is determined that the camera may be blocked from retracting, it can be further determined whether the length of time between the camera retracted from the beginning to the current moment (ie, another example of the travel time) is greater than or equal to the preset threshold #2 (ie , An example of the second threshold): If the travel time is greater than or equal to the threshold #2 (for example, 1.2 seconds (s)), it can be determined that the camera retraction is blocked. At this time, S460 can be performed; or, if the travel time is less than the threshold# 2. At this time, you can return to S420 and continue execution from S420.

In S460, the CPU controls the camera to repeatedly execute the retracting action.

It should be noted that the repeated execution of the retracting operation here means that the telescopic mechanism drives the camera to continue the retracting operation from the current position.

It should be noted that, in the method 400, S420 can be replaced with: when the travel time after the camera is retracted is equal to or greater than the threshold #2, the CPU controls the camera to take a picture and obtains the current image #2. At this time, the method 400 may not include S450, that is, if it is determined in S430 that the current image #2 is not completely covered by the shadow area, it can be determined that the camera is blocked from extending, and S460 is directly executed.

Situation #3 External force pressing

FIG. 8 shows a schematic flowchart of a detection method 500 corresponding to external force pressing. Hereinafter, each step of the method 500 will be described in detail.

In S510, after the CPU drives the camera to complete a normal extension, that is, the camera is currently in a fully extended state, that is, the camera is in a normal working state, and the CPU can issue a pressing detection instruction to the camera.

In S520, after the camera receives the press detection instruction, it executes the instruction to control the camera to take pictures, and obtain the current image #3 (that is, an example of the third target image). For example, the camera executes the press detection instruction and completes the acquisition of the current image #3 every 20 milliseconds (ms).

In S530, the CPU can determine whether the current image #3 includes a shadow area: if the current image #3 includes a shadow area, it can be determined that the camera is pressed by an external force, and execute S540; or, if the current image #3 does not include a shadow area , It means that the camera is in a normal working state, at this time, it can return to S520, and continue execution from S520.

In S540, the CPU controls the camera to perform a retracting action.

In S550, the detection ends.
