Description

Technical Field

[0001] The present application relates to a digital movie camera, which includes an electronic image sensor for generating an image signal, and a control component that, in response to a recording instruction, generates a sequence data stream representing a sequence of consecutive frames based on the image signal of the image sensor, and sends the sequence data stream to a sequence storage device to store the sequence data stream. Background Art

[0002] The image sensor of a movie camera generates an image signal based on incident light. The image sensor may have a two-dimensional matrix of photosensitive sensor elements, particularly a color filter structure arranged, for example, according to the Bayer pattern (RGGB). The movie camera may have an integrated objective lens (lens) that images a scene image on the image sensor or an objective lens mount for fixing an interchangeable objective lens. Each frame in a sequence of consecutive frames may be, for example, a corresponding full frame or half frame, which includes only complete image content and another half frame.

[0003] In film production (also known as cinematography), a large number of sequences of moving images are first recorded, and usually, a sequence of sounds associated with the sequence of moving images is also recorded. Among them, as part of post-production, the recorded image material and sound material are selected, processed, and structured so that the produced movie has its final form. This post-production is also called film editing, or synonymously film montage, shot assembly, or sequencing.

[0004] For film editing, it is necessary to mark different recorded sequences of moving images during recording so that they can be easily identified during subsequent post-production.

[0005] Usually, a so-called clapperboard is used to mark sequences of moving images. A traditional clapperboard includes a slate on which identification information to be recorded is marked. In addition, the clapperboard also has two boards that can be struck together to produce a striking sound. Since the movie image sequence and the sound sequence are usually recorded by different devices during cinematography, clear reference points or synchronization marks are required in film editing to associate the sound sequence with the image sequence at precise positions. With the help of the clapperboard, such reference points can be set in the image sequence and the sound sequence. At this reference point, the two boards of the clapperboard are struck together in the image sequence, and a striking sound can be heard in the sound sequence. Electronic clapperboards are also common. In an electronic clapperboard, information and / or time codes can be displayed through an electronic display device (such as an LED digital display).

[0006] If the image sequence and the sound sequence are not recorded by different devices, or if the sound sequence is not recorded at all, then an acoustic-optical clapping signal is not required. In this case, the identification information is simply written on the slate recorded by the movie camera.

[0007] To record a marked sequence of moving images, generally the recording operation of a movie camera is first started. Among them, a sequence data stream is generated according to the image signal of the image sensor, and when necessary, a clapperboard or slate is held up and clapped in the recording area (field of view) detected by the camera, and then the clapperboard or slate is moved away again so that the camera can record the actual sequence of moving images. During this process, the camera is always in a working state.

[0008] However, this method is not feasible in some cases. When using a telephoto lens, if macro shooting is required or if the camera is mounted on a lift, it is usually impossible to first shoot the clapperboard and then the scene in a continuous manner. In this case, it can be useful to first shoot a short sequence of moving images that only records the clapperboard, also known as the "pre-shoot" of the clapperboard, and then move the camera to the actual recording position for scene recording and adjust the camera settings (such as focus position, focal length, etc.) as needed. Between recording the clapperboard and the actual sequence of moving images, the camera is paused or made inoperative, and then the necessary parameter settings, machine assembly, and alignment are carried out.

[0009] This method has proven useful in analog movie cameras that record a sequence of frames linearly on a photochemical film. However, in the case of digital movie cameras, this approach is no longer applicable. The sequence storage device for digital cameras records in a non-linear manner, so separate moving image clips (segments) must be created for each sequence of moving images. When implementing the above "pre-shoot", the digital movie camera first creates a first segment containing the shot of the clapperboard or slate, while recording the actual scene in a second segment. However, the second segment corresponds to a separate data packet and has no direct relationship with the first segment. Therefore, how to quickly and clearly identify each piece of movie footage remains a problem. Summary of the Invention

[0010] An object of the present application is to provide a digital movie camera that can better associate the recorded scene with the identification of the recorded scene (especially in the form of the recorded clapperboard or slate).

[0011] This object can be achieved by a digital movie camera having the following features.

[0012] According to the digital movie camera of the present application, the control component is used to generate an identification image data set representing at least one scene identification image according to the image signal of the image sensor in response to identifying an image recording command, and cache the identification image data set in the buffer memory. Thereafter, the control component is further used to generate a sequence data stream identifying a continuous frame sequence (i.e., a moving image sequence) according to the image signal of the image sensor in response to a video recording instruction, and transmit the sequence data stream to the sequence storage device for storing the sequence data stream. The control component can also be used to insert the cached identification image data set into the subsequently generated sequence data stream, so that in the reproduction of the sequence data stream, the scene identification image is before the continuous frame sequence, and the sequence data stream (including the inserted identification image data set) forms a closed data stream that can be transmitted to the sequence storage device.

[0013] In other words, in the first step before generating the sequence data stream, an identification image data set is generated and cached in response to the identification image recording command. In the subsequent second step, the cached identification image data set is inserted in response to the video recording instruction.

[0014] Therefore, before recording an actual scene (movie scene) and generating the corresponding sequence data stream, first an identification image data set that can contain information to identify the scene later is generated. So the identification image data set can include, for example, the reproduction of a clapperboard or an information board. The identification image data set becomes part of the sequence data stream by being inserted into the subsequently generated sequence data stream. The continuous frames of the scene recorded in chronological order in response to the video recording instruction are encoded in the sequence data stream. The identification image data set is inserted into the subsequently generated sequence data stream so that, with respect to this chronological order, the scene identification image represented by the identification image data set is before the scene represented by the sequence data stream. In this way, the identification image data set and the sequence data stream can be clearly linked to each other.

[0015] Here, the term "reproduction of the sequence data stream" therefore means that for the sequence data stream decoded as expected or according to the convention, and for the frames represented herein reproduced as expected or according to the convention, the scene identification image appears before the scene. Thus, on a common reproduction device (such as a display screen), the scene identification image (which can be, for example, part of post-production) will be reproduced first and then the scene.

[0016] The thus generated closed data stream, that is, the sequence data stream including the inserted identification image data set, can be stored as a closed data packet in the sequence storage device, so that the frame sequence can be stored without fragmentation.

[0017] The sequence storage device can be integrated in a movie camera. Alternatively, it can be designed as an external sequence storage device, such as a video recorder, that can be connected to the movie camera, which can be connected by cable or wirelessly. In both scenarios, the sequence storage device can include at least one connector that can be accessed externally for one or more exchangeable storage media (such as removable memory cards) or at least one fixedly installed storage medium (such as at least one memory chip). Additionally, the sequence storage device can also have its own controller for controlling the storage process.

[0018] The caching of the identified image data set can be performed in a buffer memory present in or connected to the control component. In particular, the buffer memory is a volatile or non-volatile buffer memory, such as one or more memory chips.

[0019] The control component can include, for example, an integrated circuit, a microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), or a field-programmable gate array (FPGA).

[0020] According to an embodiment, the movie camera can have at least a first operating element and a second operating element. Among them, the actuation of the first operating element triggers the generation of an identification image recording command, and the actuation of the second operating element triggers a video recording instruction. The first operating element can be, for example, a fixedly assigned button or a randomly assigned key (soft key or virtual button). The second operating element can be, for example, a general recording button (REC button), especially a so-called toggle button, where the first actuation starts the recording, and the subsequent second actuation stops the already started recording. Therefore, two distinct operating elements can be provided, both of which are connected to the control component of the movie camera. Alternatively, a single operating element that can be actuated in different ways can be provided. For example, a short actuation (such as shorter than 1 second) can trigger a video recording instruction, while a long actuation (such as longer than 1 second) can trigger an identification image recording command. Generally, various types of operating elements can be provided, such as buttons, switches, knobs, or slide keys.

[0021] In particular, due to the actuation of the second operating element, any existing / previously generated / cached identified image data set can be inserted into the sequence data stream. If no such identified image data set exists, only the scene is recorded upon actuation of the second operating element; thus ensuring that the movie camera according to the present application can be used like a traditional movie camera when not allowing separate recording of scene identification images, for example, in a situation where the spatial conditions of the movie set allow the clapperboard or information board to be briefly lifted and then removed within the recording area.

[0022] Alternatively or additionally, the movie camera may have a control input through which an identification image recording command can be received from outside the movie camera and transmitted to the control unit of the movie camera. Thus, the identification image recording command can also be triggered from outside the movie camera, for example, by a camera assistant using a remote control unit separated from the movie camera. Such a remote control unit can be connected to the control input of the movie camera wirelessly (especially via radio) or wired (especially via cable). The remote control unit can also be used to transmit a video recording instruction to the movie camera, especially in the same way as the identification image recording command, through the same control input. This type of remote control unit is disclosed in German Patent DE19629484A1 and PCT Patent Application WO2010 / 046237A1.

[0023] According to another advantageous embodiment of the present application, the control unit of the movie camera is used to transmit a sequence data stream including inserted identification image data sets to a sequence storage device so that the sequence data stream can be stored in a single data packet, especially in a single file. For this purpose, the sequence data stream is transmitted to the sequence storage device as a closed data stream (especially a continuous data stream) and stored in a non-fragmented manner. Therefore, both the original sequence data stream representing the actual scene and the inserted identification image data sets can be stored in the same data packet, especially in the same file. The data packet or the file can be saved, for example, in one of the formats ARRIAW, ProRes, RAW, XAVC, XF-AVC.

[0024] The movie camera preferably has a sequence storage device, where the movie camera is used to store the sequence data stream in a single data packet, especially in the form of a so-called container file. A container file or container format is a data structure through which individual data streams of possibly different formats can be combined into a data stream, for example, to form the container file (multiplexing). A container usually contains data of different formats. Thus, taking the so-called AVI container as an example, it is known to include, for example, an MPEG-4 video track created by the Xvid codec and an MP3 audio track created by an encoder such as LAME. Some container formats can also include other data, such as subtitles, menu structures, or other audio tracks. Preferably, the container file is processed for insertion with the help of the control unit and / or the sequence storage device, especially together with other data or data streams, such as an audio data stream or metadata.

[0025] According to another embodiment, the control unit of the movie camera is used to compress the sequence data stream before or during storage. In this regard, lossless or lossy data compression processing can be used, and data compression can be performed both in the control unit and the sequence storage device.

[0026] In some embodiments, the inserted recognition image data set is located at the beginning of the sequence data stream. Thus, when post-processing the recorded sequence data stream, the recognition image data set stored therein can be visualized as quickly as possible to enable effortless recognition of the recorded scene.

[0027] According to one embodiment, the recognition image data set represents a single scene recognition image. In particular, only a single scene recognition image is generated in response to a recognition image recording command, and only the single scene recognition image is also inserted into the sequence data stream.

[0028] Alternatively, the recognition image data set can represent a scene recognition sequence including multiple frames. The scene recognition sequence can consist of multiple consecutively captured frames or multiple copies of a single frame. The scene sequence can thus be a recorded short film or a series of scene recognition images based on a single scene recognition image that is subsequently copied. In this regard, the number of images in the scene recognition sequence can be a preset default value or can be changed by the user. For example, the number of images can be determined by a corresponding setting in a setup menu or also by the actuation duration of an operating element set for generating the recognition image recording command.

[0029] According to another embodiment of the present application, one or more frames existing in the original sequence data stream can be replaced with the inserted recognition image data set; in particular, the number of frames to be replaced can be equal to the number of images in the recognition image data set. In some embodiments, the first frame or multiple frames exactly at the beginning of the original sequence data stream can be replaced with the recognition image data set, and the replaced frames can also be discarded. Since the recognition image data set must be directly stored first after generating a recording instruction, but the sequence data stream with scene images can already be stored at this moment, at least the need for necessary buffering of the sequence data stream is reduced in this design. Replacing each frame with the inserted recognition image data set can be achieved by a control component of the movie camera.

[0030] According to another embodiment, the control component can be used to initiate the generation and storage of the sequence data stream only in response to a recording instruction and not in response to a recognition image recording command.

[0031] Once the recognition image data set is generated and cached, a relevant signal can be sent to the user of the movie camera via a corresponding symbol in the electronic viewfinder of the movie camera and / or via another external visual display (which can be particularly arranged at a first operating element).

[0032] According to another embodiment, the control component can be used to store the recognized image dataset in the buffer memory until the control component receives a recording instruction; thereby ensuring that it is not necessary to directly receive the recording instruction after generating and caching the recognized image dataset, but there may also be a time delay in this case.

[0033] According to yet another embodiment, the control component of the movie camera can be used to delete the recognized image dataset due to the actuation of the associated operating element before inserting the recognized image dataset into the subsequently generated sequential data stream; thereby preventing the inadvertently insertion of recognized image datasets that may be incorrectly generated or are no longer needed into the subsequently generated sequential data stream. Thus, repeatedly actuating the above-mentioned first operating element, or actuating the operating element for a long time, can, for example, delete or overwrite the previously generated and cached recognized image dataset. For example, the recognized image dataset is recorded when the operating element is actuated for the first time, the previously recorded recognized image dataset is deleted when actuated for the second time, and a new recognized image dataset is recorded when actuated for the third time. Alternatively, a short first actuation of the operating element can record the recognized image dataset; a long second actuation can delete the previously recorded dataset, and a short second actuation can cause the new recognized image dataset to overwrite and replace the current image dataset. Alternatively, a third operating element can also be set as the "delete button" for the recognized image dataset.

[0034] According to still another embodiment, the control component of the movie camera can be used to control the playback device to reproduce the scene recognition image corresponding to the cached recognized image dataset. Thus, in particular, the user (such as a photographer) can assure himself that the correct scene recognition image is cached and available for the subsequent recording of the sequential data stream (corresponding to the moving image sequence) before triggering the recording instruction. The playback device can be, for example, an integrated monitor or an electronic viewfinder of the movie camera, or an external monitor (connected wirelessly or wired) to the image signal output of the movie camera. In particular, the reproduction of such a scene recognition image can be triggered by the actuation result of the corresponding operating element that is at least indirectly connected to the control component of the movie camera.

[0035] Independent of the described movie camera, the present application also relates to a remote control component for remotely controlling a remote control component associated with a movie camera of the described type. The remote control component is used to selectively generate and transmit an identification image recording command or a video recording instruction to the associated movie camera. The identification image recording command includes an instruction to generate an identification image data set representing at least one scene identification image, and the video recording instruction includes an instruction to generate a sequence data stream representing a sequence of consecutive frames. The remote control component may have an evaluation and control device for selectively generating an identification image recording command or a video recording instruction. The evaluation and control device may include, for example, any type of integrated circuit or microprocessor. The remote control component may also have a signal output through which the generated identification image recording command and the generated video recording instruction can be transmitted wirelessly (in particular by radio) or wiredly (in particular by cable) to the associated movie camera.

[0036] Similar to the above explanation regarding the movie camera, such a remote control component may have a first operating element and a second operating element. Actuation of the first operating element triggers the generation and transmission of an identification image recording command to the movie camera and its transmission to the display. Actuation of the second operating element triggers the generation and transmission of a video recording instruction to the movie camera. Alternatively, the remote control component may also have a single operating element that can be actuated in different ways to selectively generate and transmit an identification image recording command or a video recording instruction to the movie camera.

[0037] The remote control component can also be used to remotely control a camera for security purposes, particularly to remotely control the corresponding objective lens actuation (drive) motor (e.g., adjusting the focus position, focal length, or aperture). In this embodiment, the remote control component has at least one movable operating element (e.g., an adjustment wheel) for setting an objective lens control command. The evaluation and control device of the remote control component is used to generate a corresponding objective lens control signal based on the set objective lens control command and transmit it to the movie camera.

[0038] On the other hand, the remote control component can be configured as described above regarding the movie camera and can also be configured as described in German Patent DE19629484A1 and PCT Patent Application WO2010 / 046237A1.

[0039] Other advantageous embodiments of the present application can be derived from the description and the drawings. Description of the Drawings

[0040] The present application will be described below with reference to embodiments and the drawings, where the drawings include the following:

[0041] Figure 1 is a schematic block diagram of a digital movie camera according to the present application;

[0042] Figure 2 It is a schematic diagram of a sequence data stream. Detailed implementation

[0043] Figure 1 Schematically shown is a digital movie camera 10 having an objective lens 12, which can be configured as an interchangeable lens or can be fixedly connected to the movie camera 10. The objective lens 12 images the images captured by the image sensor 14, which can be, for example, a CMOS image sensor or a CCD image sensor. The image sensor 14 converts the captured images into an electronic image signal and transmits it to the control unit 16.

[0044] The control unit 16 is used to receive, process, and transmit the image signal. In addition, the control unit 16 can also be used to receive control commands from different components of the movie camera 10 and / or transmit control commands to these components. The control unit 16 can have a modular design. The control unit 16 is connected to a buffer memory 18 that caches image data sets (which can include single images or short image sequences), that is, the control unit can store the image data sets in the buffer memory 18 and can also read them out again.

[0045] The control unit 16 is also connected to a sequence storage device (here simply referred to as the storage device 24), and is connected to a connection member 28 for an external storage device or a sequence storage device, so as to transmit the image signal in the form of a sequence data stream 40 to the storage device 24 for storage or to an external storage device connected to the connection member 28. In this embodiment, the storage device 24 includes a swappable storage medium 26, such as a solid-state memory. In a variant embodiment of the movie camera 10, it is also possible to selectively provide only the internal storage device 24 or only the connection member 28 for the external storage device.

[0046] In order to monitor and check the images acquired by the image sensor 14, an electronic viewfinder 30 connected to the control unit 16 and equipped with an electronic image display device (display) can be provided.

[0047] In addition, the control unit 16 is connected to a first operating element 20 and a second operating element 22 that can be designed as, for example, push buttons. Alternatively or additionally, the first operating element 20 and the second operating element 22 can also be provided outside the movie camera 10, especially on a related remote control component.

[0048] The working modes of the movie camera 10 will be elaborated in more detail below with reference to Figure 1 and Figure 2 The working modes of the movie camera 10 will be elaborated in more detail below with reference to

[0049] Before the recording scenario, an identification image data set capable of identifying the subsequently recorded scenario must first be generated. To this end, a clapperboard or information board on which the information required to identify the next scenario is written or displayed is first photographed.

[0050] To generate this identification image data set, the user of the movie camera 10 first actuates the first operating element 20, i.e., he / she briefly presses the button on the first operating element 20, thereby triggering an identification image recording command that can cause the control unit 16 to generate an identification image data set based on the image signal of the image sensor 14. In this embodiment, the identification image data set only includes a single scenario identification image 42, and this scenario identification image 42 includes a reproduction of the clapperboard or information board.

[0051] In a variant embodiment, due to the actuation of the first operating element 20, a scenario identification sequence with multiple frames can also be captured, where the length or number of frames can be a preset default value or a user-defined preset value. The length of the scenario identification sequence can be determined, for example, by a corresponding menu entry or by the actuation duration of the first operating element 20. It is also conceivable that a first brief actuation of the first operating element 20 causes the capture of the scenario identification sequence, and another actuation stops the capture.

[0052] The obtained identification image data set with the scenario identification image 42 or the scenario identification sequence is transferred from the control unit 16 to the buffer memory 18 for caching. Subsequently, the movie camera 10 can be used to record the actual scenario, which can, for example, include changes in the position of the movie camera 10 or changes in the objective settings (such as focal length, focus).

[0053] In a variant embodiment, it is possible to signal whether there is an identification image data set in the viewfinder 30 and / or signal whether there is another display device at the movie camera 10. For example, the signaling in the viewfinder 30 can be achieved by fading in the corresponding symbol in the image display device.

[0054] If the current actual scenario is to be recorded subsequently, the movie camera 10 or the recording operation of the movie camera 10 can be started by actuating the second operating element 22, i.e., by transmitting a video recording instruction to the control unit 16. After receiving the video recording instruction, the control unit 16 starts to generate a sequence data stream 40 and transfers it to the storage device 24 and the connection member 28. In this regard, the scenario identification data set with the scenario identification image 42 is first transmitted, and immediately thereafter, the frames 44A - 44C of the actual moving image sequence generated due to the video recording instruction are transmitted.

[0055] As long as the recording operation of the movie camera 10 is started to shoot a scene, the sequence data stream 40 is stored as a closed data stream on the storage medium 26 and / or the sequence data stream 40 is stored in the form of a closed data packet or a closed file on the storage medium of an external storage device connected to the connection member.

[0056] The recording of the sequence data stream 40 can be ended by actuating the second operating element 22 again, thereby closing the data packet or file. Repeatedly generated recording instructions generate new data packets or new files. Adding additional frames to an already closed file is technically impossible or at least not allowed so as to be able to distinguish different scenes.

[0057] Therefore, Figure 2 In the figure, the scene recognition image 42 is shown first in chronological order from left to right, and then the continuous sequence 44A - 44C of each image.

[0058] In summary, the cached recognition image data set is inserted into the subsequently generated scene sequence data stream, so that in the reproduction of the sequence data stream 40, the scene recognition image 42 of the recognition image data set is before the continuous frame sequence 44A - 44C (as Figure 2 shown), and the sequence data stream 40 including the inserted recognition image data set forms a closed data stream.

[0059] Here, the term "reproduction of the sequence data stream" means that when the sequence data stream 40 is decoded as expected and the frames 42, 44A - 44C represented herein are reproduced as expected, the scene recognition image 42 appears before the scenes 44A - 44C.

[0060] The data packet or file generated by the storage of the sequence data stream 40 may even include other data, such as metadata (such as the time data or setting data of the camera). These other time or metadata can be stored at any desired location in the data packet or file, especially can be stored in multiple locations, particularly at the beginning of the data packet or file.

[0061] The first frames 44A - 44C have been directly generated after triggering the recording instruction by operating the second operating element. However, at this time, the recognition image data set must be saved first. To prevent the loss of the frames of the generated moving image sequence, a constantly existing buffer memory or an additional buffer memory can be used to cache the moving image sequence. Or, the frames of the generated moving image sequence can be discarded until the recognition image data set has been completely inserted into the sequence data stream 40 and stored.
