Description

Technical Field

[0001] This invention relates to a photographic device, and more particularly to a wearable photographic device that can activate the recording function by tapping. Background Technology

[0002] With the development of technology, modern people use various photographic devices to record various situations in their daily lives. For example, when traveling, users can use handheld photographic devices (such as smartphones) to take pictures of scenery and people. When engaging in outdoor sports (such as skiing, rock climbing, etc.), users can use wearable photographic devices to take pictures of the scene in front of them from a first-person perspective, so as to make their hands more flexible. Wearable photographic devices are also often worn by specific personnel (such as law enforcement officers, security personnel, etc.) to record images of specific personnel during their duties. These images are used as objective evidence to facilitate subsequent investigations.

[0003] Existing wearable photography devices typically have at least one control button. When a user presses this control button, the device can be activated to record video, take photos, or perform other functions. However, during the duty of certain personnel, unforeseen circumstances may occur, preventing them from pressing the control button. In other words, the hardware components of existing wearable photography devices are limited, resulting in the failure to record images of unforeseen circumstances in a timely manner, which affects the subsequent investigation of the incident. Therefore, it is imperative to improve existing wearable photography devices. Summary of the Invention

[0004] Existing wearable photography devices have limited hardware components, resulting in images not being recorded in certain situations (e.g., when the user's hands are holding other objects). In view of this, the present invention proposes a wearable photography device comprising: An accelerometer for generating at least one sensing signal; A controller, electrically connected to the accelerometer, receives the at least one sensing signal and generates a control signal; and A lens is electrically connected to the controller, and the lens receives the control signal to start recording video.

[0005] The wearable photography device of this invention incorporates an accelerometer, enabling additional extended functions. For example, the accelerometer can generate at least one sensing signal by tapping, causing the controller to activate the lens to begin recording. Therefore, even when the user is holding other objects, they can still operate and activate the recording function of the wearable photography device. Compared to existing technologies, where buttons are located in specific positions and users may need to locate them by touch rather than press them immediately, the recording activation method of this invention (tapping the device) is faster than the existing method (pressing a button), improving the applicability of this invention. For example, it can be used by specific personnel (law enforcement officers, security personnel, etc.) during their duties. In the event of an emergency, the personnel can quickly tap to activate the recording function of this invention, thus fully recording the video of the emergency as objective evidence.

[0010] To gain a detailed understanding of the technical features and practical effects of the present invention, and to enable its implementation according to the invention, the following detailed description is provided with reference to the embodiments shown in the figures:

[0011] Please see Figures 1 to 3 The wearable photography device of the present invention includes an accelerometer 10, a controller 20, and a lens 30. Specifically, as shown in the figure... Figure 2 As shown, the wearable photography device has a housing 40 with a first surface 41 and a second surface 42 facing each other. The accelerometer 10, the controller 20 and the lens 30 are disposed in the housing 40. The shooting window of the lens 30 is exposed on the first surface 41 of the housing 40 to capture images outside the first surface 41. The second surface 42 is provided with a wearing mechanism 43, which allows the user to fix the wearable photography device to their body.

[0012] The accelerometer 10 is used to generate at least one sensing signal S1. Specifically, the accelerometer 10 can sense the acceleration change of the wearable camera device to generate the at least one sensing signal S1. For example, when a user hits the wearable camera device, the shaking generated by the hitting is transmitted to the accelerometer 10 through the housing 40, causing the accelerometer 10 to also generate the at least one sensing signal S1 due to the shaking. The accelerometer 10 can be, for example, a three-axis accelerometer, but the present invention is not limited thereto.

[0013] The controller 20 is electrically connected to the accelerometer 10 to receive the at least one sensing signal S1, and the controller 20 generates a control signal S2 based on the at least one sensing signal S1. For example, the controller 20 may be a microcontroller (MCU), a single-chip microcomputer, etc., and the present invention is not limited thereto.

[0014] In one embodiment of the present invention, the controller 20 generates the control signal S2 based on the speed at which the wearable camera device is continuously tapped, as described below. The at least one sensing signal S1 includes a first sensing signal and a second sensing signal, meaning that when the user continuously taps the wearable camera device, the accelerometer 10 continuously generates the first sensing signal and the second sensing signal, wherein there is an interval between the generation of the first sensing signal and the generation 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. The controller 20 presets a time threshold and determines whether the interval is less than or equal to the time threshold. When the controller 20 determines that the interval is less than or equal to the time threshold, the controller 20 generates the control signal S2; conversely, when the controller 20 determines that the interval 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.

[0015] In another embodiment of the invention, the controller 20 generates the control signal S2 according to the force of hitting the wearable camera device, as described below. The controller 20 has several preset signal size segments, which are formed by several signal thresholds of different sizes. For example, the signal size segments include a first signal size segment, a second signal size segment, and a third signal size segment. The first signal size segment is between a first signal threshold and a maximum signal threshold. The second signal size segment is between a second signal threshold and the maximum signal threshold. The third signal size segment is between a third signal threshold and the maximum signal threshold. For example, if the first signal threshold is 30 (signal strength units), the second signal threshold is 50 (signal strength units), the third signal threshold is 70 (signal strength units), and the maximum signal threshold is 90 (signal strength units), then the first signal size segment is between 30 and 90 (signal strength units), the second signal size segment is between 50 and 90 (signal strength units), and the third signal size segment is between 70 and 90 (signal strength units).

[0016] The controller 20 can be configured to use one of the several signal size ranges as the criterion 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 several signal size ranges. How the controller 20 is configured to use one of the several signal size ranges as the criterion will be explained further later. When the controller 20 determines that the magnitude of the at least one sensing signal S1 is within one of the several signal size ranges, the controller 20 generates the control signal S2. Conversely, when the controller determines that one of the at least one sensing signal S1 is not within one of the several signal size ranges, the controller 20 does not execute any program and waits to receive the at least one sensing signal S1 again.

[0017] Please refer to the following: 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 into the storage device. The storage device can be, for example, a memory installed in the housing 40, a memory card inserted into the housing 40, etc. The present invention is not limited thereto.

[0018] Please see Figures 2 to 4The wearable photography device may also include a function indicator light 50, which is electrically connected to the controller 20. For example, the function indicator light 50 may be a colored light-emitting diode. The first surface 41 of the housing 40 has a light-transmitting area 410, and the function indicator light 50 is disposed in the light-transmitting area 410. The light of the function indicator light 50 can be emitted through the light-transmitting area 410 to indicate the operating status of the wearable photography device to the user.

[0019] When the lens 30 starts recording video, the controller 20 controls the function indicator light 50 to flash in a breathing pattern. When the lens 30 is not recording video, the controller 20 controls the function indicator light 50 to remain constantly lit. Specifically, when the lens 30 starts recording video, as shown in the image... Figure 2 and Figure 3 As shown, the user can control the lens 30 to stop recording images via a recording stop button 44 on the housing 40. Specifically, when the user presses the recording stop button 44 during the recording process of the lens 30, the controller 20 will be triggered to control the lens 30 to stop recording images.

[0020] Please refer to the following: Figure 4 The wearable photography device may also include a wireless network (WiFi) module 60, which is electrically connected to the controller 20 for connecting the controller 20 to a first external device (not shown). For example, the first external device may be a smartphone. 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 indicator light 50 to blink in a first light color. When the controller 20 is connected to the first external device through the wireless network module 60 and the lens 30 is not recording images, the controller 20 controls the function indicator light 50 to remain constantly lit in the first light color.

[0021] Furthermore, the wearable photography device may also include a Bluetooth module 70, which is electrically connected to the controller 20 for connecting the controller 20 to a second external device. For example, the second external device may be another wearable photography device of the present invention. In other words, the wearable photography device can connect with other wearable photography devices through the Bluetooth module 70 to establish a shooting group. When the controller 20 connects to the second external device through the Bluetooth module 70 and the lens 30 starts recording images, the controller 20 controls the function indicator light to blink in a second light color. When the controller 20 connects to the second external device through the Bluetooth module 70 and the lens 30 is not recording images, the controller 20 controls the function indicator light 50 to remain constantly lit in the second light color.

[0022] The controller 20 can also simultaneously connect to the first external device and the second external device via the wireless network module 60 and the Bluetooth module 70, respectively. When the controller 20 is connected to the first external device and the second external device via the wireless network module 60 and the Bluetooth module 70, respectively, and the lens 30 starts recording video, the controller 20 controls the function indicator light 50 to breathe and flash with a third light color. When no video is being recorded, the controller 20 controls the function indicator light 50 to remain constantly lit in the third light color; conversely, when the controller 20 is not connected to any device through the wireless network module 60 and the Bluetooth module 70 and the lens 30 starts recording video, the controller 20 controls the function indicator light 50 to breathe and flash in a fourth light color. When the controller 20 is not connected to any device through the wireless network module 60 and the Bluetooth module 70 and the lens 30 is not recording video, the controller 20 controls the function indicator light 50 to remain constantly lit in the fourth light color.

[0023] Regarding how the controller 20 is set to use one of the several signal strength segments as the judgment criterion, when the controller 20 is connected to the first external device through the wireless network module 60, the first external device can execute an application (APP). The user can use the application to set the controller 20 to use one of the several signal strength segments as the judgment criterion. For example, when the first external device executes the application, several trigger strength options are displayed on the display screen of the first external device. These trigger strength options correspond to the several signal strength segments respectively. The user can select one of the several trigger strength options to set the controller 20 to correspond to the signal strength segment of the trigger strength option.

[0024] Furthermore, the wearable camera device also includes at least one warning light 80 and a control button 90. The 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... Figure 2 and Figure 3 As shown, the control button 90 is located on the housing 40. When the user presses the control button 90, the controller 20 can detect a voltage change generated by the control button 90, and the voltage change is the trigger signal S3.

[0025] 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 at 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 at a second brightness, and the first brightness is greater than the second brightness. For the user's operation, when the user presses the control button 90 for the first time, the at least one warning light 80 flashes at the first brightness. When the user presses the control button 90 for the second time, the at least one warning light 80 flashes at the second brightness. When the user presses the control button 90 for the third time, the at least one warning light 80 turns off. The at least one warning light 80 is controlled in this cyclical manner.

[0026] It should be noted that during the flashing or constant illumination of the function indicator light 50, when the controller 20 receives the at least one trigger signal S3, the controller 20 will control the function indicator light 50 to turn off and the at least one warning light 80 to turn on according to the at least one trigger signal S3. In other words, the wearable camera does not have a state where the function indicator light 50 and the at least one warning light 80 are turned on at the same time.

[0027] The wearable photography device of this invention incorporates an accelerometer 10, enabling additional extended functions. For example, the accelerometer 10 can generate at least one sensing signal S1 by tapping, causing the controller 20 to control the lens 30 to start recording. Therefore, even when the user is holding other objects, they can still operate and activate the recording function of the wearable photography device. Compared to the prior art, where buttons are located in specific positions on existing wearable photography devices, users may need to find them by touch rather than press them immediately. The recording activation method of the wearable photography device of this invention (tapping the device) is therefore faster than the recording activation method of existing wearable photography devices (pressing buttons), improving the applicability of this invention. For example, it can be used by specific personnel (law enforcement officers, security personnel, etc.) during their duties. In the event of an emergency, the personnel can quickly tap to activate the recording function of this invention and record the complete video footage of the emergency as objective evidence.

Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
