Description

The present invention is based on a technology that reads a two-dimensional array symbol from an image input unit, decodes the two-dimensional array symbol, and extracts information, and uses the decoded result information as control data of the device or data stored in the device. For the technical field.

In a camera recorder, the texture and expression method of an image that is created after shooting varies depending on shooting conditions and camera recorder setting parameters. Also, since the parameters to be set are diverse, it is very difficult to reproduce the same setting contents. As a conventional technique, setting parameters of a camera recorder are recorded in an external memory typified by an SD card and the like, and the same settings are realized by reading them into other equipment. Since a physical recording medium is interposed, the setting is limited to one unit at a time. As another method, it is also possible to set a plurality of camera recorders at a time without exchanging physical data using a technology such as a wireless LAN. However, when it is realized by a function that is not normally added to the camera recorder such as a wireless ALN, a cost is required.
Therefore, a two-dimensional code, which is an encoding technique often used in a camera-equipped mobile phone, which is an existing technique, is used. This existing technology provides Internet address information and e-mail address information as a two-dimensional code to a user as paper or image information like a camera-equipped mobile phone, and allows the camera-equipped cellular phone to read the two-dimensional code. It is widely used in a form in which two-dimensional code composite processing is performed and converted into address information for use.
In addition, by applying this technology, the operating status and setting status of a device are displayed on the screen as 2D barcode information when the device is activated, and the email is read by the mobile phone with a camera. There is a maintenance method as disclosed in Patent Document 1 in which maintenance can be performed from a remote location.

JP 2007-271806 A

  I want to easily set multiple camera recorders such as shooting conditions at the same time. At that time, without using a physical external recording medium, etc., on the other hand, we would like to use hardware resources provided in conventional camera recorders to reduce the additional cost.

  In the prior art, as shown in FIG. 1, the device information of the projector 101 is projected on the screen 102, the projected image is read by the camera-equipped mobile phone 104, the read two-dimensional code is subjected to complex processing, and e-mail is sent. There is a maintenance method to send the message to the maintenance center and tell the symptom.

  Although it is possible to know the operating state of one device, there is a problem that it is impossible to reflect the setting parameters on that device or to use the same setting for a plurality of devices at the same time.

  Further, in the case of the projector 101 described in the related art example, if the function to project itself does not function, such as when a malfunction occurs, there is a problem that the information path is interrupted because the display itself cannot be performed.

  With respect to the display of the two-dimensional code, the display is output to the liquid crystal display unit of the camera recorder 201 or the external monitor 203 as shown in FIG. On the other hand, regarding the reading of the two-dimensional code, as shown in FIG. 4, the camera recorder 201 is configured to photograph and read the subject two-dimensional code.

  As shown in the configuration diagram of the camera recorder in FIG. 7 in the fourth embodiment, the configuration in actual use is such that a liquid crystal display unit 202 is configured in the camera recorder 501 and an external monitor 203 can be connected. The external monitor 203 can be attached and detached. The internal functions of the camera recorder 501 are shown in the camera recorder function block in FIG. The most important functional element is that it has a parameter 2D code conversion function 505 and a main video 2D code superimposing function 506.

  Each configuration will be described in detail in the best mode for carrying out the invention.

It is possible to notify parameter information such as shooting conditions from a single camera recorder to a plurality of camera recorders, and to perform equivalent shooting condition settings at a time. In order to realize them, the functional elements of the conventional camera recorder are used as they are, and are realized at low cost.

The figure showing the two-dimensional code output of the camera recorder in the present Example 4 The figure showing the 2-dimensional code reading of the camera recorder in the present Example 4.

The best embodiment will be described below with reference to the configuration diagrams of the respective camera recorders of FIGS. 2, 4, and 7.

In the configuration of the camera recorder of FIG. 2, functional blocks of the camera recorder 201 are shown in FIG. A monitor output function and a liquid crystal display function are provided to realize a two-dimensional code output function, and setting parameters inside the camera recorder 201, such as shooting conditions and operating conditions of the camera recorder 201, are selected and determined in advance. It has a function to convert menu information and other information into a two-dimensional code. The converted two-dimensional code is output as an image via a monitor output function or a liquid crystal display function.
Thus, the camera recorder according to claim 1 which can display the internal information as a two-dimensional code is realized. Although the internal information of the camera recorder 201 is a two-dimensional code, this two-dimensional code may be a code that performs error correction, such as a QR code. The encoding method of the two-dimensional code and the combination method when reading the two-dimensional code described later must be made common.

  In the configuration of the camera recorder in FIG. 4, functional blocks of the camera recorder 202 are shown in FIG. In order to realize the input of a two-dimensional code, it has a photographing function and an encoding function, and has a function of recognizing and decoding a photographed image as a two-dimensional code. The arrangement of the data is determined by the arrangement of the black part and the white part of the two-dimensional code, and the binary data is decoded. The decoding method, that is, the decoding of the encoded code described in the first embodiment is performed. If the decoded information is main body information such as shooting conditions, the device settings of the camera recorder 202 can be made by converting the parameters into the parameters of the camera recorder 202 and writing them as setting parameters.

  In addition to the realization method described so far, the camera recorder according to claim 2 is realized by combining with the function of outputting the two-dimensional code described in the first embodiment so that the main body information such as photographing conditions can be outputted and decoded.

  When you start reading, you can start by pressing a button for reading a two-dimensional code separately from this button, such as a shooting start / stop button, or you can press a button to start and stop shooting two-dimensionally. There are several ways to start reading the code. On the other hand, completion of reading is determined to be complete when the code is analyzed and recognized as data as a result of reading the two-dimensional code.

  An embodiment for further improving convenience based on the method described so far will be described below. Embodiments of the camera recorders of claims 3, 4 and 5 will be described.

  The captured image is not only a two-dimensional code but also a subject such as a landscape or a person. A function of superimposing image data obtained by converting a setting parameter into a two-dimensional code on the main video when the main video of the subject such as a landscape or a person is output to the liquid crystal display unit 202 or the external monitor 203; Thus, it is possible to output a main image including two-dimensional code information. It is a camera recorder of Claim 3.

  Two-dimensional codes cannot handle very large data. In the case of large data, the fineness of the image is required so that the two-dimensional code can be accurately read and analyzed. The liquid crystal display unit of the camera recorder 202 is difficult to display a high-definition image, and needs to be relatively small data in order to increase the accuracy of reading a two-dimensional code. Therefore, relatively small data can be handled in a time-sharing manner, and large data can be handled by reconnecting them. Fig. 7 shows an example of 2D code output. The period from 1 to n is performed while switching the 1 / n split display. The first two-dimensional code has a start meaning, and the n-th two-dimensional code has an end meaning. The camera recorder according to claim 4.

  By indicating how long the n-th two-dimensional code is apart from the first two-dimensional code in the first two-dimensional code, the n-th 2 having the meaning of the end after that time elapses. An abnormal system that does not reach the dimension code can be considered. In addition, an abnormal system in which an intermediate two-dimensional code is skipped by considering the number of two-dimensional codes up to the n-th two-dimensional code, that is, n in advance, in the first two-dimensional code is considered. be able to.

  Assuming that there is some abnormality in reading, the error is reduced by resuming from the two-dimensional code indicating the first, that is, the start, next to the two-dimensional code having the meaning of the nth end.

  If all n two-dimensional codes from the start to the end can be read, the decoded data of those codes are connected and handled as a series of data strings, so that a large amount of data, such as photographic image data, can be handled. It becomes. The camera recorder according to claim 5.

Embodiments of the camera recorders of claims 6, 7 and 8 will be described.
The camera recorder outputs a main video obtained by photographing a subject such as a landscape or a person to the liquid crystal display unit 202 or the external monitor 203. At the same time, the video is recorded on a recording medium such as an external memory. On the other hand, a two-dimensional code other than the image of the subject is displayed and output on the same liquid crystal display unit 202 and external monitor 203.
By having a function of superimposing image data obtained by converting setting parameters into a two-dimensional code and a main video obtained by photographing a subject, and having a function of recording the main video including the two-dimensional code on a recording medium, recorded data A camera recorder capable of creating a camera will be described.

  The camera recorder 501 captures the subject 503, and the captured image is recorded on a recording medium via the functional block imaging function, encoding function, and recording function of the camera recorder 501. At the same time, the subject video input to the shooting function is output and displayed on the display unit via the monitor output function and the liquid crystal display function.

  If the subject video is simply output to the display unit without superimposing the two-dimensional code, it is as described above. However, if the two-dimensional code is also to be output simultaneously to the display unit, this subject video and the setting parameters of the camera recorder 501 It is necessary to superimpose an image of a two-dimensional code generated from. With the main video two-dimensional code superimposing function of the camera recorder 501, the superimposition bitmap is regenerated in the output frame memory, and the image data is output to the display unit. Further, by recording the image data, it is possible to record a composite image in which the subject video and the two-dimensional code are superimposed. The camera recorder according to claim 6.

  By repeating the operation of superimposing the image of the two-dimensional code generated from the setting parameter of the camera recorder 501 while changing the two-dimensional code generated when a certain time has passed, the data of the setting parameter is handled in a time-sharing manner. FIG. 7 In the configuration diagram of the camera recorder in the fourth embodiment, a case where it is divided into two-dimensional codes 1 to n is shown.

  The parameter ⇔ two-dimensional code conversion function enables bidirectional data conversion. In addition to the output of the two-dimensional code described above, it also has a function of reading the two-dimensional code and writing setting parameters to the device. That is, it is a camera recorder equipped with both functions of receiving setting information from the outside and setting it as its own setting value, and displaying the setting value of itself and providing the setting information.

  As for recording on a recording medium, a plurality of recording media, for example, recording data for broadcast production that does not include a two-dimensional code is recorded on a large-capacity recording medium, and auxiliary recording image data to be referred to in editing is relatively large A small usage, for example, recording on an SD memory card is also assumed. The camera recorder according to claim 7. When recording from the recording function to the recording medium, if the data input to the recording function is from the encoding function, only the subject image and not the two-dimensional code image is included. On the other hand, if the data input to the recording function is from the main video two-dimensional code superimposing function 506, an image on which the subject and the two-dimensional code are superimposed is recorded.

Use the selection menu in the device setting information to determine on which recording medium only the subject video or the subject video and the two-dimensional code superimposed image is to be recorded. The recording image is selected and recorded on the previous recording medium. The camera recorder according to claim 8.
If the superimposed image of the subject video and the two-dimensional code image is widely disclosed to the user as a photographed sample, for example, it is possible to reproduce the setting conditions photographed by a professional photographer close to the camera recorder as one of promotional activities. It is possible to provide value-added functions.

This is a useful technique in a device that similarly holds setting information in a system that has both an image input system and an image output system such as a camera recorder.
The same applies to the still camera. However, even if the image input system is not a CCD or a CMOS sensor, for example, a two-dimensional code can be similarly read out by a scanner, a copier, a multifunction machine, etc., and an image can be output.
