[0001] The invention relates to a system and a method for remotely activating a storage operation of image information, a portable digital device for remotely activating the storage of image information and a recording device.

[0002] In particular, the invention relates to personal portable devices and sports equipment where the user wishes to record image information in the form of video material of processes and situations and to store it for later viewing, editing and sharing with others. Description of the state of the art

[0003] Various approaches to the problem of recording, editing, viewing, and sharing video information with personal devices are known. One such approach is presented in US Patent 8613937, which discusses the management of video information distributed by sending and receiving it with a mobile device. The content is not created or edited by the user in any way; rather, filtering and accounting features are provided for the content itself.

[0004] Another method is described in US patent 8214139, in which a navigation device can be configured to trigger various actions based on GPS positioning, a detected change in location, or acceleration. However, these recording devices are triggered exclusively by position data, with the length of the recording material determined by external conditions.

[0005] Another method is described in US patent application 2013 / 0343729, which discusses a system for semi-automatic video processing. The system is based on an algorithm for evaluating and classifying offered video content, resulting in a compiled and edited version of the input material, which includes selected sequences of the original video material based on actions, facial expressions, etc.

[0006] US 6,359,837 B1 discloses a combination of a camera and a wristwatch and a novel application of a wristwatch including a display device. The camera has a recording device for electronically recording an image of an object and a transmission device for transmitting the recorded image on a radio wave. The wristwatch has a display device capable of displaying the current time and the current image, a playback device for receiving the radio wave from the camera located at a nearby position and for reproducing the image, and a display control device for controlling the display device to display the reproduced image.

[0007] US 2013 / 0250134 A1 discloses a system with a remote control including an interface for receiving commands from a user (e.g., to turn a camera on and off) and a transceiver for transmitting the commands to one or more camera transceivers connected to cameras.

[0008] US 2005 / 0111036 A1 discloses a remote control device that searches for an image data storage device and a printing device that can be used by a user and notifies an image pickup device of device information obtained as a result of this search.

[0009] US 2002 / 0081976 A1 discloses a wristwatch with a wireless communication function, comprising a watch module having a mechanically driven time display element that displays time, a wireless communication circuit that sends and receives data to and from an external wireless device by wireless communication, the wireless communication circuit including a memory that stores data, and a timepiece control unit that controls the time display element to display information in accordance with the stored data.

[0010] US 2014 / 0176775 A1 discloses an imaging device capable of capturing a combined photograph, which is a single image composed of a plurality of images, and capable of displaying a live view image. The device includes a first display section, a second display section, an imaging section for converting an object image into image data, an image processing section for subjecting the image data to image processing, and a combined photograph processing section.

[0011] US 2007 / 0104476 A1 discloses a camera system for photographing an object as a preview photograph and as a regular photograph and for displaying the image of the preview photograph and the image of the regular photograph, comprising a storage section for storing image data as the regular photograph and as the preview photograph of the object photographed by the photographing section, wherein, when a control section controls the photographing section to photograph the object as the regular photograph after the preview photograph, an image display section displays the preview photograph of the object based on the image data previously stored in the storage section.

[0012] US 8 467 270 B2 discloses a smartwatch comprising a wristband, a base, a battery and a first auxiliary component, wherein the base is coupled to the wristband and comprises a housing, a processor and a wireless transceiver in communication with the processor.

[0013] During sporting and outdoor activities, it is often desirable to collect memories in the form of video footage, for example, from an event or a mountain hike. There is no shortage of cameras for recording such material, including cameras built into smartphones or PDAs. The subsequent editing of such video material is time-consuming and laborious. During sports training, too, it would be important for the trainee and / or coach to record certain sequences of a process, possibly multiple times, for later analysis. Longer video sequences are not readily suitable for locating, isolating, and viewing critical process steps, which may last only a fraction of a second.

[0014] There is therefore a need for a system capable of recording video clips only when needed, without significant user effort and without requiring the camera to be held in place. Furthermore, there is a need to minimize necessary editing, giving the video clips a known length and time period close to the triggering event, allowing them to be easily reviewed for acceptance or rejection. DISCLOSURE OF THE INVENTION

[0015] It is therefore an object of the present invention to provide a solution to the above problems, a solution based on two separate devices with a wireless connection between them and sensors connected to one or both of the devices. The system, method, and devices according to the invention offer an efficient solution for collecting only relevant video material in the vicinity of triggered events during a sporting exercise or excursion of any kind. The video clips collected in this way can be easily sequenced to tell a "complete" story, or they can be easily browsed to select the most suitable ones for immediate sharing over a network or for editing.

[0016] The system according to the invention for remotely activating a storage operation of image information comprises: - a first portable digital device having an interface for receiving commands from a user and a memory unit for storing these commands, a processing unit for executing computer programs using the commands as input values, and a wireless transmission unit for communicating with external devices via a wireless connection; - at least one second device comprising a recording device configured to be set to a mode of continuous recording of image information, a memory, and a wireless transmission system for communicating with external devices via a wireless connection.

[0017] The processing unit in the first portable digital device is configured to issue commands containing trigger information to be sent via the wireless connection to the second digital device to instruct the storage of at least a portion of the continuously recorded image information in the memory of the at least one second device, in response to and in accordance with the trigger information.

[0018] The first portable digital device is equipped with at least one sensor or a connection to at least one external sensor device, and is designed to send the commands containing the trigger information based on the sensor signals to cause the storage of image information in the at least one second device.

[0019] In a second embodiment, the second digital device can be equipped with at least one sensor or with a connection to at least one external sensor device and can be configured to transmit sensor signals to the first portable digital device via the wireless connection. The first portable digital device is then configured to issue commands based on the sensor signals that cause image information to be stored in a second device.

[0020] In a third embodiment, the second digital device may be equipped with at least one sensor or a connection to at least one external sensor device and configured to receive commands containing trigger information issued by the first portable digital device via the wireless connection, and to interpret sensor signals that match the trigger information received from the at least one sensor or external sensor device as an input signal for initiating storage of image information. In this case, the first portable digital device does not need to send storage commands in real time via the wireless connection; instead, the second device has received a "pre-warning" from the trigger information sent in advance, indicating at which event or sensor signal value the storage process should begin.

[0021] According to a further embodiment, the first portable digital device may comprise a manual input device for providing the input signal for causing the storage of image information and for issuing storage commands to be sent to the second device via the wireless connection.

[0022] In one embodiment, the first wearable digital device is a wristop computer, a smart watch, a computer-equipped wristwatch, a personal digital assistant, or a dive computer worn on the visitor's wrist. The second device may be a wearable digital camera, a smartphone equipped with a digital camera, or it may be one or more standalone or other digital cameras. The cameras may be constructed or equipped to be waterproof for underwater use during diving operations. In one embodiment, the camera is configured to store image information in the form of video clips in its memory at a predetermined time period before and / or after a save command.

[0023] The portable device according to the invention for remotely activating the storage of continuously recorded image information in a remote device comprises: - an interface for receiving commands from a user, and a storage unit for storing the commands, - a processing unit for executing computer programs using the instructions as input, - a wireless transmission unit for communicating with remote devices via a wireless connection, and - at least one sensor or a connection to at least one external sensor device.

[0024] The processing unit is configured to send, based on sensor signals from the sensor or the connection to at least one external sensor device, commands containing trigger information to be sent via the wireless connection to the external digital device in order to instruct storage of at least a portion of the continuously recorded image information in the remote device in response to and in accordance with the trigger information.

[0025] The portable digital device may further comprise at least one sensor or a connection to at least one external sensor device and be configured to issue commands based on the sensor signals to initiate the storage of image information in the remote device. Alternatively or additionally, the device may include a manual input device for providing the output signal to initiate the storage of image information.

[0026] In one embodiment, the wearable digital device is a wristop computer, a smart watch, a computerized wristwatch, a personal digital assistant, or a dive computer worn on the user's wrist.

[0027] The inventive concept includes, for forming a pair with the portable digital device, a recording device which contains a recording device and is capable of being set into a mode of continuous recording of image information, comprising: - at least one digital camera designed to record image information, - at least one memory, - a wireless transmission system for communicating with remote devices via a wireless connection.

[0028] The recording device is equipped with a device which, in response to a command received via the wireless connection from a remote digital device, is designed to activate the camera in order to store image information in the at least one memory.

[0029] According to one embodiment, the recording device may contain at least one sensor or a connection to at least one external sensor device. It may then transmit the sensor signals to the remote digital device via the wireless connection as input for a process executed therein, which is configured to issue commands regarding the storage of image information.

[0030] In a further embodiment, the recording device may comprise at least one sensor or a connection to at least one external sensor device and be configured to receive commands containing trigger information from the remote digital device via the wireless connection. The recording device then initiates the storage of captured image information when it receives sensor signals from the sensor devices that match the trigger information.

[0031] The recording device can be a portable digital camera or a smartphone equipped with a digital camera. It can be one or more digital cameras, standalone devices, or otherwise separate devices. The cameras can be waterproofed or designed for use in underwater diving operations.

[0032] The recording device may be configured to store recorded image information in the form of video clips in its memory, wherein the information is recorded over a predetermined period of time before and / or after receipt of a storage command.

[0033] The inventive concept also comprises a method for activating a storage operation of image information, comprising the following steps: - Providing a first portable digital camera with a wireless transmission system; - Providing at least one second device with a recording device adapted to be set in a continuous recording mode for image information, with a memory, and with a wireless transmission system; - generating commands in the first portable device to instruct storage of image information in the second device; - transmitting the commands to the second device via a wireless connection using the wireless transmission system; - receiving the commands in the at least one second device and in response to and in accordance with the commands, causing at least a portion of the continuously recorded image information to be stored in a memory of the recording device; - forming sensor signals from at least one sensor device in the first portable digital device; and - Sending the commands containing the trigger information based on the sensor signals via the wireless connection to initiate storage of image information in the at least one second digital device.

[0034] In one embodiment, the method may further comprise the following steps: - in the second device, generating sensor signals from at least one sensor device; - transmitting the sensor signals to the first portable digital device via a wireless connection using the wireless transmission system; - in the first portable digital device, issuing commands based on the sensor signals via the wireless connection to initiate storage of image information in the at least one second digital device.

[0035] In a third embodiment, the method according to the invention may further comprise the following steps: - in the first portable digital device, sending commands via the wireless connection, which commands contain trigger information regarding the storage of image information in the at least one second digital device; - generating sensor signals from at least one sensor device in the second device; - Interpreting sensor signals matching the trigger information received from the at least one sensor device as the input signal for initiating the storage of image information.

[0036] The method according to the invention may include the step of providing, in the first portable digital device, the input signal for initiating the storage of image information and for issuing storage commands for transmission via the wireless connection to the second digital device using a manual input device. In one embodiment, the step of storing, in the at least one second device, image information recorded as video clips of a predetermined length may also be provided, wherein each clip is recorded over a predetermined period of time before and / or after the issuance of a storage command.

[0037] The invention offers considerable advantages as an efficient solution for collecting only relevant video material in the area of ​​triggered events during an exercise or field trip of any kind. The collected video clips are concatenated, thus telling the "complete" story of the event, but it is also very easy to browse through the video clips to select the appropriate clip(s), for example, for immediate sharing over a network or for editing.

[0038] With the present invention, the user spends less time editing video footage to capture the moments they want to save. The inventive concept also saves storage space on memory cards, such as those typically used in digital cameras. The use of pre-built or custom applications to manage image recording allows the user to define the conditions under which recording takes place.

[0039] It is an essential feature of the present invention that the recording device is configured to operate in a mode of continuous recording of image information. When the camera is switched on, it records a certain amount of video material and stores it in memory, with new material overwriting older material, much like a continuous tape recording. Only when a command is issued to initiate storage of the recorded image information is it permanently stored in the camera's memory. This facilitates the storage of video material recorded immediately before the save command is issued, as well as material recorded immediately after the command.The recording period, which is obviously user-configurable and depends heavily on the nature of the event, can use the entire time period for storing the video signal until the save command is issued, with the recording period being centered around the save command. The period can begin with the save command, or there can be a combination of the above possibilities.

[0040] For the purposes of the following description and context, the words "recording" and "capture" are used interchangeably to describe the process of capturing video material, at least temporarily, in a recording device set to a continuous recording mode. The word "storage" and its related derivatives, including "storage," are used to refer to video material or video clips that are actually permanently stored for later viewing, editing, and / or sharing.

[0041] The wireless communication system that creates a wireless connection can be based on radio technologies such as Bluetooth or RFID, or any other short-range communication system. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows the main components of the system according to the invention; Fig. Figure 2 shows a wristop computer and a camera unit according to the invention in greater detail; Fig. Figure 3 shows an example of the system according to the invention when carried by the user; Fig. 4 shows an example of the system according to the invention in which a component of the system is stationary; Fig. Figure 5 shows a schematic representation of video clips recorded according to the invention; Fig. Figure 6 shows a flowchart of a video clip storage procedure according to the invention. DETAILED DESCRIPTION OF THE INVENTION

[0042] Fig. Figure 1 shows the main components of the system according to the invention: a wristop computer 1 and a unit 2 containing a video camera and a general-purpose computer 3 with a connection to an external network (not shown). If the camera unit 2 is a smartphone or tablet computer with a built-in external (internet) network connection, the computer 3 may be unnecessary. Furthermore, not all connections between the devices are necessarily two-way. For example, in some embodiments of the invention, the wristop computer can transmit exclusively to the camera unit 2, but cannot also receive from it.

[0043] The general-purpose computer or an internet-based service can provide a programmable user interface for the wristop computer 1. In addition to the usual data selection and necessary inputs, such as selecting display types and colors for the wristop computer 1, available measurement data is read from the wristop computer 1 to the other computer 3 and various software selected by the user is downloaded. An important task for the user interface available on the computer 3 (or the camera unit 2, if appropriately equipped) is to enable the setting or editing of parameters for the various applications running on the wristop computer.These applications depend on the sensors available for the wristop computer 1 and the user's needs, and the parameters may typically be sensor value trigger levels for activating the camera unit 2, video clip recording times, and the like.

[0044] It can be seen that the two-way connection between the computer system 3 and the wristop computer 1 facilitates a user interface editing system installed in the computer 1, which can be used to edit a user interface of predefined applications running on the wristop computer 1. It is also within the scope of the invention to store the data and customized views in a format that is transferable as files to other devices or social media, or to remote services, for example, on the Internet, for accounting and further processing.

[0045] In Fig. 2, the wristop computer 1 and the camera unit 2 are shown in greater detail. The wristop computer 1 has a processing unit 21 for executing computer programs and applications. A user interface unit 22 receives manual commands entered by the user, for example, via push buttons 26. A memory unit 23 serves to store operating systems, application program code, and received commands. A sensor interface 24 forms a wired connection to one or more built-in sensors (not shown) and / or to a wired or wireless connection (see above) to external sensor devices. Typically, the sensors can be accelerometers, gyroscopes, or other orientation-sensing switches, timers, GPS devices, shock sensors, inclinometers, and the like.

[0046] A wireless transmission unit 25 is required for communication with the camera unit 2 and / or possible external computers 3 via a wireless connection, as indicated by the arrow L. The wireless connection protocol for the connection between the computers and / or between possible remote sensors can be Bluetooth LE or the proprietary ANT+ protocol. These use direct sequence spread spectrum (DSSS) modulation methods and an adaptive isochronous network configuration. Explanatory descriptions of the hardware required for various wireless connection implementations are available, for example, from the Texas Instruments° manual "Wireless Connectivity," which contains IC circuits and associated hardware configurations for protocols operating in the sub-1 and 2.4 GHz frequency bands, such as ANT™, Bluetooth ® , Bluetooth ® low energy, RFID / NFC, PurePath™ Wireless audio ZigBee ®, IEEE 802.15.4, ZigBee RF4CE, 6LoWPAN, WiFi ® , GPS.

[0047] In Fig. Figure 3 depicts a man on a snowboard with a wristop computer 30 attached to his wrist and a camera 31 attached to his forehead by means of suitable fastening means. Obviously, the camera can be attached to any part of the clothing, but also to the snowboard. The wireless connection L creates wireless communication between the two devices 30 and 31. When appropriately programmed, the wristop computer sends commands to the camera 31 to start saving video clips when the ground speed, vertical speed, or acceleration (on a steep slope) exceeds a certain limit, or when gravity (the absence of vertical acceleration) is zero or below a certain limit, which means that the snowboarder is performing a jump through the air.The trigger function can be based on any physical variable that the sensors can detect, whereby the trigger rules can be incorporated through an editing function to account for any combination of such variables, as explained further below in the examples. Editors for designing and editing triggers are known as such from the prior art. In this context, it is also possible and within the scope of the invention to equip the camera 31 with suitable sensors in order to send commands from the wristop computer 30 to the camera 31 in advance, which contain trigger information. During the process, the camera 31 interprets the received sensor signals and attempts to match them with the trigger information. If a match is found, the storage of image information is initiated.

[0048] In Fig. Figure 4 illustrates the use of the present inventive system for one embodiment of alpine skiing, wherein the camera 41 is fixedly installed and the wristop computer 40 is attached to the wrist (or elsewhere) of a user and serves to activate the camera 41 via the wireless connection L so that a clip is saved when the user approaches or passes within the camera's line of sight. In this way, repeated recordings can be made, for example, for training or comparison purposes. It will be appreciated that it is within the scope of the invention to install any number of cameras at a distance from one another or at different angles relative to an event location or along a route. The cameras can be triggered manually or automatically, for example, using a proximity sensor.The conditions at some event locations, such as the takeoff point of a ramp, easily create conditions that can trigger the sensors in the wristop computer 31 to trigger the camera to record the event. Other monitored event locations, such as on board a sailboat, are more likely to be considered for manual or proximity triggering.

[0049] Fig. Figure 5 is a schematic and exemplary representation of video clips VC1...VC6 stored in a semiconductor or magnetic memory. Thumbnail icons T1-T6, which illustrate the content of each of the video clips, can be viewed for an immediate decision on how to proceed with each of the clips. Of course, there are a variety of processing techniques, and it is not necessary for the invention here to deal with the technique of managing video clips in detail.

[0050] Fig. Figure 6 shows a flowchart of a basic video clip storage procedure according to the invention. In step 60, the wristop computer 1 monitors Fig. 2 the sensor signals. If the input signals in a test 61 exceed the preset readout threshold to start storing video material, a command to this effect is issued at 62 and transmitted to the camera unit 2 in step 63. In this example, the camera unit records the next 15 seconds of video material and stores the material together with the previous 15 seconds of recorded video in a video clip, as shown in Fig.5. Obviously, and similarly, the entire length of the clip from the video material recorded before the command could be saved, stopping saving at the command itself. Conversely, the entire length of the clip of video material recorded after the command could be saved, stopping after a predetermined time. EXAMPLES 1. Ski stunts

[0051] The user wants to record the biggest jumps / stunts for his friends. After each successful jump, pressing the button saves 30 seconds of the recorded video footage before the button was pressed. The user can pre-define the length of the saved footage. / / If the user moves and is in free fall for more than 2 seconds: Record a video clip 30 seconds before and 30 seconds after. if(SUUNTO_SPEED > 10 && SUUNTO_C[2] < 1 { ACTIVATE.CAMERA_AFTERTHOUGHT(30); clipsrecorded = clipsrecorded+1; / / show how many clips have been recorded RESULT = clipsrecorded; 2. Use of a fixed and a mobile device

[0052] Here, a user wants to capture short clips without the need / ability to manipulate the camera while driving. Proximity detection can be based on signal strength detection, or it can be location-based using GPS. For example, the Bluetooth Low Energy (BLE) standard enables proximity detection. Other signal strength-based options include ultrasonic detection, for example, in underwater applications, or inductive short-range wireless devices (telemetry devices). With location-based proximity detection, both the wristop computer and the camera can have GPS capability, or only one of the devices can have this capability while driving, provided the location of the stationary device is entered into the GPS navigator.

[0053] Other useful applications include snowboarding with a helmet camera, diving past a stationary camera, and sailing boats past a turning buoy. Filming a skateboard trick with a camera mounted on the helmet is also possible, for example, using the following code: / / When the user approaches the camera, start filming. if(SUUNTO_PROXIMITY < 15 && recording == 0){ ACTIVATE.CAMERA_RECORD(); recording = 1; / / when user is gone, stop recording}else if (SUUNTO_PROXIMITY > 15 && recoreding == 1){ ACTIVATE.CAMERA_STOP(); recording = 0;} 3. Mountain bike

[0054] The user wants to film the downhill sections (at high speed) of a mountain bike ride. They want to control the camera automatically when their hands cannot be removed from the handlebars. if(SUUNTO_SPEED > 30 && recording == 0){ ACTIVATE.CAMERA_RECORD(); recording = 1;}else if (SUUNTO_SPEED < 20 && recording == 1){ ACTIVATE.CAMERA_STOP(); recording = 0;}

[0055] During such a tour, the user will want to record the best views, spots, jumps, etc. The buttons on the wristop computer can then be used to mark the spots for later editing. The markers can be saved in the camera's memory as short clips to allow for faster editing.
