TECHNICAL FIELD
[0001] The utility model relates to a photography device, in particular to a wearable photography device which can start the video recording function by the way of patting. BACKGROUND
[0002] With the development of science and technology, modern people record various situations in daily life through various photography devices. For example, when going out for travel, the user can shoot scenery, figures, etc. through a handheld photography device (such as a smart phone), and when engaging in outdoor sports (such as skiing, rock climbing, etc.), the user can shoot the scene in front of him through a wearable photography device in the first person perspective, so as to be flexible with both hands. The wearable photography device is also often worn on the body of a specific person (such as a law enforcement officer, a security guard, etc.) to record the image of the specific person during the on-duty process. The image is used as objective evidence to facilitate subsequent event investigation.
[0003] The existing wearable photography device usually has at least one control button. When the user presses the at least one control button, the video recording, photographing, etc. function of the wearable photography device can be started. However, during the on-duty process of the aforementioned specific person, a sudden situation may occur so that he has no time to press the at least one control button with his hand. In other words, the existing wearable photography device has limited hardware elements, which leads to the fact that the image of the sudden situation is not recorded in time and affects the progress of subsequent event investigation. Therefore, it is necessary to improve the existing wearable photography device. SUMMARY
[0004] The existing wearable photography device has limited hardware elements, which leads to the fact that the image is not recorded in some cases (such as when the user holds other appliances with both hands). In view of this, the utility model provides a wearable photography device, which comprises:
[0005] An acceleration sensor is used to generate at least one sensing signal;
[0006] A controller is electrically connected to the acceleration sensor. The controller receives the at least one sensing signal and generates a control signal; and
[0007] A lens is electrically connected to the controller. The lens receives the control signal and starts recording the image.
[0008] The acceleration sensor is added in the wearable photographing device, so that the wearable photographing device has additional expansion functions, for example, the acceleration sensor can generate the at least one sensing signal through a beating mode, so that the controller controls the lens to start recording images, so that the user can operate to start the recording function of the wearable photographing device when the user holds other instruments with both hands, compared with the prior art, because the button is arranged on a specific position of the existing wearable photographing device, the user may need to find and press immediately by the touch mode, the starting recording mode (beating the body) of the wearable photographing device is faster than the starting recording mode (pressing the button) of the existing wearable photographing device, and the application of the wearable photographing device is improved, for example, the wearable photographing device is used in the on-duty process of specific personnel (law enforcement personnel, security personnel and the like), when an emergency occurs, the specific personnel can quickly beat to start the recording function of the wearable photographing device, and complete recording of image pictures of the emergency, so as to serve as objective evidence.

[0013] In order to understand the technical features and practical effects of the utility model in detail, and can be implemented according to the content of the utility model, further embodiment as shown in the drawing is described in detail as follows:
[0014] Please refer to Figures 1 to 3 The wearable photographing device includes an acceleration sensor 10, a controller 20 and a lens 30, specifically, as shown in Figure 2 The wearable photographing device has a shell 40, the shell 40 has a first surface 41 and a second surface 42 opposite to each other, the acceleration sensor 10, the controller 20 and the lens 30 are arranged in the shell 40, wherein the shooting window of the lens 30 is exposed to the first surface 41 of the shell 40 to shoot image pictures outside the first surface 41, the second surface 42 is provided with a wearing mechanism 43, and the wearing mechanism 43 can be used to fix the wearable photographing device on the body of the user.
[0015] The acceleration sensor 10 is used to generate at least one sensing signal S1, specifically, the acceleration sensor 10 can sense the acceleration change of the wearable photographing device to generate the at least one sensing signal S1, for example, when the user taps the wearable photographing device, the shaking generated by tapping is transmitted to the acceleration sensor 10 through the casing 40, so that the acceleration sensor 10 also generates the at least one sensing signal S1 due to the shaking, the acceleration sensor 10 may, for example, be a three-axis acceleration sensor, and the utility model does not limit it.
[0016] The controller 20 is electrically connected to the acceleration sensor 10 to receive the at least one sensing signal S1, and the controller 20 generates a control signal S2 according to the at least one sensing signal S1, for example, the controller 20 may, for example, be a microcontroller (MCU), a single-chip microcomputer, etc., and the utility model does not limit it.
[0017] In an embodiment of the utility model, the controller 20 generates the control signal S2 according to the speed of continuously tapping the wearable photographing device, which will be described below. The at least one sensing signal S1 includes a first sensing signal and a second sensing signal, that is, the user continuously taps the wearable photographing device, so that the acceleration sensor 10 continuously generates the first sensing signal and the second sensing signal, wherein there is an interval time between the generation time of the first sensing signal and the generation time of the second sensing signal. When the controller 20 receives the first sensing signal, the controller 20 receives the second sensing signal after the interval time, the controller 20 is preset with a time threshold and judges whether the interval time is less than or equal to the time threshold; when the controller 20 judges that the interval time is less than or equal to the time threshold, the controller 20 generates the control signal S2, otherwise, when the controller 20 judges that the interval time is greater than the time threshold, the controller 20 does not execute any program and waits to receive the at least one sensing signal S1 again.
[0018] In another embodiment of the present application, the controller 20 generates the control signal S2 according to the force with which the wearable camera is tapped, as will be described later. The controller 20 is pre-set with a plurality of signal magnitude sections formed by a plurality of signal thresholds of different magnitudes. For example, the plurality of signal magnitude sections include a first signal magnitude section, a second signal magnitude section, and a third signal magnitude section. The first signal magnitude section is between a first signal threshold and a maximum signal threshold. The second signal magnitude section is between a second signal threshold and the maximum signal threshold. The third signal magnitude section is between a third signal threshold and the maximum signal threshold. For example, the first signal threshold is 30 (unit of signal intensity), the second signal threshold is 50 (unit of signal intensity), the third signal threshold is 70 (unit of signal intensity), and the maximum signal threshold is 90 (unit of signal intensity). Thus, the first signal magnitude section is between 30 and 90 (unit of signal intensity), the second signal magnitude section is between 50 and 90 (unit of signal intensity), and the third signal magnitude section is between 70 and 90 (unit of signal intensity).
[0019] The controller 20 can be configured to use one of the plurality of signal magnitude sections as a basis for determining whether to generate the control signal S2. That is, the controller 20 determines whether the magnitude of the at least one sensing signal S1 is within one of the plurality of signal magnitude sections. How the controller 20 is configured to use one of the plurality of signal magnitude sections as a basis will be described later. When the controller 20 determines that the magnitude of the at least one sensing signal S1 is within one of the plurality of signal magnitude sections, the controller 20 generates the control signal S2. Otherwise, when the controller determines that the magnitude of one of the at least one sensing signal S1 is not within one of the plurality of signal magnitude sections, the controller 20 does not execute any program and waits for the at least one sensing signal S1 again.
[0020] Please refer to Figure 1 The lens 30 is electrically connected to the controller 20 to receive the control signal S2. The lens 30 starts recording images according to the control signal S2. In addition, the controller 20 and the lens 30 can also be connected to a storage device (not shown). The controller 20 can store the images recorded by the lens 30 in the storage device. The storage device can be, for example, a memory disposed in the casing 40, a memory card inserted into the casing 40, or the like. The present application is not limited in this regard.
[0021] Please refer to Figures 2 to 4The wearable photographing device can further comprise a function prompt lamp 50 electrically connected to the controller 20. For example, the function prompt lamp 50 can be a colored light emitting diode. The first surface 41 of the casing 40 has a light transmission region 410. The function prompt lamp 50 is arranged on the light transmission region 410. The light of the function prompt lamp 50 can be emitted through the light transmission region 410 to prompt the user about the operation state of the wearable photographing device.
[0022] When the lens 30 starts recording images, the controller 20 controls the function prompt lamp 50 to breathe and flash. When the lens 30 does not record images, the controller 20 controls the function prompt lamp 50 to constantly emit light. When the lens 30 starts recording images, the user can control the lens 30 to stop recording images through a recording stop button 44 on the casing 40. Specifically, when the user presses the recording stop button 44 during the recording of images by the lens 30, the controller 20 is triggered to control the lens 30 to stop recording images. Figure 2 and Figure 3 When the lens 30 starts recording images, the controller 20 controls the function prompt lamp 50 to breathe and flash. When the lens 30 does not record images, the controller 20 controls the function prompt lamp 50 to constantly emit light. When the lens 30 starts recording images, the user can control the lens 30 to stop recording images through a recording stop button 44 on the casing 40. Specifically, when the user presses the recording stop button 44 during the recording of images by the lens 30, the controller 20 is triggered to control the lens 30 to stop recording images.
[0023] Please refer to Figure 4 The wearable photographing device can further comprise a wireless network (WiFi) module 60 electrically connected to the controller 20 to connect the controller 20 to a first external device (not shown). For example, the first external device can be a smart phone. When the controller 20 is connected to the first external device through the wireless network module 60 and the lens 30 starts recording images, the controller 20 controls the function prompt lamp 50 to breathe and flash with a first lamp color. When the controller 20 is connected to the first external device through the wireless network module 60 and the lens 30 does not record images, the controller 20 controls the function prompt lamp 50 to constantly emit light with the first lamp color.
[0024] Further, the wearable photographing device can further comprise a Bluetooth module 70 electrically connected to the controller 20 to connect the controller 20 to a second external device. For example, the second external device can be another wearable photographing device of the present application. In other words, the wearable photographing device can be connected to other wearable photographing devices through the Bluetooth module 70 to establish a shooting group. When the controller 20 is connected to the second external device through the Bluetooth module 70 and the lens 30 starts recording images, the controller 20 controls the function prompt lamp to breathe and flash with a second lamp color. When the controller 20 is connected to the second external device through the Bluetooth module 70 and the lens 30 does not record images, the controller 20 controls the function prompt lamp 50 to constantly emit light with the second lamp color.
[0025] The controller 20 can also connect the first external device and the second external device through the wireless network module and the Bluetooth module respectively. When the controller 20 connects the first external device and the second external device through the wireless network module 60 and the Bluetooth module 70 respectively and the lens 30 starts recording images, the controller 20 controls the function prompt light 50 to breathe and flash in a third light color. When the controller 20 connects the first external device and the second external device through the wireless network module 60 and the Bluetooth module 70 respectively and the lens 30 does not record images, the controller 20 controls the function prompt light 50 to constantly light in the third light color. Conversely, when the controller 20 does not connect any device through the wireless network module 60 and the Bluetooth module 70 and the lens 30 starts recording images, the controller 20 controls the function prompt light 50 to breathe and flash in a fourth light color. When the controller 20 does not connect any device through the wireless network module 60 and the Bluetooth module 70 and the lens 30 does not record images, the controller 20 controls the function prompt light 50 to constantly light in the fourth light color.
[0026] As to how the controller 20 is set to one of the signal size sections as a judgment basis, when the controller 20 connects the first external device through the wireless network module 60, the first external device can execute an application program (APP). The user can set the controller 20 to one of the signal size sections as a judgment basis through the application program. For example, when the first external device executes the application program, the display screen of the first external device displays a plurality of trigger force options, which correspond to the plurality of signal size sections respectively. The user can select one of the plurality of trigger force options, so that the controller 20 is set to the signal size section corresponding to the selected trigger force option.
[0027] In addition, the wearable photographing device also includes at least one warning light 80 and a control button 90. The at least one warning light 80 and the control button 90 are electrically connected to the controller 20. The control button 90 is used to generate at least one trigger signal S3. The controller 20 receives the at least one trigger signal S3 to control the on-off state of the at least one warning light 80 according to the at least one trigger signal S3. Specifically, as shown in Figure 2 and Figure 3 The control button 90 is arranged on the casing 40. When the user presses the control button 90, the controller 20 can detect a voltage change generated by the control button 90, which is the trigger signal S3.
[0028] For example, the at least one trigger signal S3 includes a first trigger signal and a second trigger signal, when the controller 20 receives the first trigger signal, the controller 20 controls the at least one warning light 80 to flash with a first brightness, when the controller 20 receives the second trigger signal, the controller 20 controls the at least one warning light 80 to flash with a second brightness, and the first brightness is greater than the second brightness, for the user's operation, that is, when the user presses the control button 90 for the first time, the at least one warning light 80 flashes with the first brightness, when the user presses the control button 90 for the second time, the at least one warning light 80 flashes with the second brightness, when the user presses the control button 90 for the third time, the at least one warning light 80 is then turned off, the at least one warning light 80 is controlled in this way.
[0029] It should be noted that, in the process of flashing or constant brightness of the function prompt light 50, when the controller 20 receives the at least one trigger signal S3, the controller 20 will control the function prompt light 50 to be turned off and the at least one warning light 80 to be started according to the at least one trigger signal S3, in other words, the wearable camera does not have the state that the function prompt light 50 and the at least one warning light 80 are started at the same time.
[0030] The acceleration sensor 10 is newly added in the wearable camera of the utility model, so that the utility model can have additional expansion functions, for example: the acceleration sensor 10 can generate the at least one sensing signal S1 by means of beating, so that the controller 20 controls the lens 30 to start recording images, therefore, although the user holds other appliances with both hands, the user can still operate to start the recording function of the wearable camera, compared with the prior art, because the button is arranged on a specific position of the existing wearable camera, the user may need to find it by touching and cannot press it immediately, the starting recording mode (beating the body) of the wearable camera of the utility model is therefore faster than the starting recording mode (pressing the button) of the existing wearable camera, which improves the applicability of the utility model, for example, for use by specific personnel (law enforcement personnel, security personnel, etc.) during on-duty, when an emergency occurs, the specific personnel can beat quickly to start the recording function of the utility model, and complete recording of the image picture of the emergency, as objective evidence.
[0031] The above merely is preferred embodiment of the present application and does not limit the present application in any form, although the present application has been disclosed as above with the preferred embodiment, however, is not used to limit the present application, any skilled person in the art, without departing from the scope of the technical scheme of the present application, can make some changes or modifications to the above disclosed technical content for equivalent embodiments of equivalent changes, but as long as the content of the technical scheme of the present application is not deviated, according to the technical essence of the present application, any simple modification, equivalent change and modification of the above embodiments are still within the scope of the technical scheme of the present application.
