Description

  The present invention relates to an electronic device having an imaging function and a television broadcast receiving function.

In recent years, mobile phones with an imaging function have been rapidly developed, and for example, a mobile phone equipped with a solid-state imaging device having 2 million pixels is commercially available. On the other hand, mobile phones with built-in TV tuners have also appeared (Non-Patent Document 1). Here, in the mobile phone with an imaging function, the copyright relating to the image or video taken by itself belongs to the photographer, so it is not possible to copy these or send them to a third party by attaching an email. Usually free. On the other hand, copyrights related to still images or moving images of TV programs are not inherently attributed to the user of the mobile phone, so it is usually not possible to copy these or send them to a third party by attaching an email. There seems to be a limitation.

  Here, since an image obtained by imaging and an image acquired from a broadcast video cannot be distinguished as an image signal, there is a possibility that confusion will occur if they are stored in a memory. For example, in principle, a user who has taken an image can freely distribute or copy an image obtained by imaging. However, in the case of an image obtained from the aired video, distribution may be prohibited without the permission of the copyright holder, but the mobile phone user unknowingly attaches it to a third party by e-mail. In some cases, it may be transmitted, or the entire memory may be transferred to another person, making it difficult to protect the copyright holder.

  The present invention has been made in view of these problems, and an object of the present invention is to provide an electronic device that can achieve both protection of the copyright holder and user-friendliness.

  An electronic apparatus according to a first aspect of the present invention includes an imaging unit that performs imaging to generate first image data, a tuner unit that receives a television signal and generates an image signal from the television signal, and the image signal An electronic device comprising: extraction means for extracting at least a part of the second image data as second image data; and a memory for recording the first image data and the second image data. The image data is recorded in the memory in association with information indicating that it is a different type of data from the first image data generated by the imaging unit, so that the image data is identified based on the information. Therefore, for example, the first image data obtained from the image sensor can be transferred externally, but the second image data extracted by the extracting unit cannot be transferred externally. It is possible to easily perform different handling in sea urchin electronic apparatus side, even while reducing the convenience of the user of the electronic device, it is possible to protect the copyright owner of the rights of the image based on the television signal. In this specification, “image” includes a moving image without sound and a moving image with sound in addition to a still image. In this specification, image data is processed to obtain image data. However, an already processed image signal is treated as the same as the image data.

  The information is preferably included in the incidental information in the second image data, but is not limited thereto.

  An electronic apparatus according to a second aspect of the present invention includes an imaging unit that performs imaging to generate first image data, a tuner unit that receives a television signal and generates an image signal from the television signal, and the image signal An electronic device comprising: extraction means for extracting at least a part of the second image data as second image data; and a memory for recording the first image data and the second image data. Since the image data is recorded in the memory in a different directory from the first image data, the image data can be identified based on the directory. For example, the first data generated by the imaging unit Image data can be transferred externally, but the second image data extracted by the extracting means is handled differently on the electronic device side such that external transfer is impossible. It is possible to carry out the easily, even while reducing the convenience of the user of the electronic device, it is possible to protect the copyright owner of the rights of the image based on the television signal.

  The second image data is preferably recorded in the memory with a file name different from that of the first image data. When the file name is composed of, for example, three alphabetic characters and four or five numbers, the four or five numbers are often assigned in ascending order for each image data. It is preferable to make the image data different from the second image data.

  An electronic apparatus according to a third aspect of the present invention includes an imaging unit that performs imaging to generate first image data, a tuner unit that receives a television signal and generates an image signal from the television signal, and the image signal An electronic device comprising: extraction means for extracting at least a part of the second image data as second image data; and a memory for recording the first image data and the second image data. Since the image data is recorded in the memory with an identifier different from that of the first image data, the image data can be identified based on the identifier. For example, the image data generated by the imaging unit The first image data can be transferred externally, but the second image data extracted by the extracting means can be handled differently on the electronic device side, such that external transfer is impossible. It is possible, even while reducing the convenience of the user of the electronic device, it is possible to protect the copyright owner of the rights of the image based on the television signal.

  The second image data is preferably recorded in the memory with a directory different from that of the first image data.

  ADVANTAGE OF THE INVENTION According to this invention, the electronic device which can make protection of a copyright owner and user's usability compatible can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view (a) and a rear view (b) of a mobile phone T with an imaging function according to the present embodiment. The mobile phone T will be described. As shown in FIG. 1, in the mobile phone T, an upper housing 171 as a case having a display screen 174 and a lower housing 172 having an operation button group 16 are connected via a hinge 173. The imaging unit 100 including a lens and a CCD is built under the display screen 174 on the inner surface side (the side having the display screen 174) of the upper housing 171, and the lens 42 (see FIG. The light can be taken in from the outer surface of the upper housing 171 through 2).

  A mode switch 41 is disposed on the side surface of the lower housing 172. The mode switch 41 is slidable upward and downward from the center position shown in the figure. Normally, the mode switch 41 is at the center position and sets the call mode (or mail transmission mode). When sliding, the control unit 8 (FIG. 2) switches from the call mode to the camera mode accordingly. In the camera mode, imaging can be performed by operating the release switch R. On the other hand, when the mode switch 41 is slid downward, the control unit 8 switches from the call mode to the television mode accordingly. In the television mode, a television image can be displayed on the display screen 174 based on an image signal generated by the TV tuner unit 50 (FIG. 2).

  FIG. 2 is a block diagram showing a configuration of the mobile phone T with an imaging function according to the present embodiment. In the case where the call mode is set, in FIG. 2, in the transmitting unit 2, for example, the voice emitted from the user from the condenser microphone 21 or the like is converted into a voice signal through the microphone 21, and then the voice codec 11, The signal is output to the transmission unit 23 via the channel codec 12 and the modulation unit 22, and transmitted from the diversity antenna 14 to the other party via the external telephone or the like by the SWIC 13. In addition, the transmission unit 23 as a communication unit attaches image data corresponding to the image stored in the FROM 51 or the removable memory card 7 according to an instruction from the control unit 8 under a predetermined condition by attaching a mail. It can be sent to the terminal.

  On the other hand, when the receiver 3 receives a transmission signal from the other party by the SWIC 13 via the diversity antenna 14 and the receiver 31 receives the other party's voice via the demodulator 32, the channel codec 12, and the voice codec 11. It is configured to be heard from the receiver 33 and the speaker 34.

  A TV tuner unit (also referred to as a tuner unit) 50 acquires an analog broadcast signal or a digital broadcast signal (collectively referred to as a television signal) via an antenna (not shown), and generates an image signal based on the analog broadcast signal or digital broadcast signal. Here, the image signal generated by the TV tuner unit 50 is displayed as a visible image on the display screen 174. When the user who views the image signal operates the release switch R, for example, the control is an extraction means. The unit 8 can extract at least a part of the image signal as image data (second image data). The extracted image data is stored in the FROM 51 or the memory card 7 which is a memory selected by the card controller 52. For example, when the release switch R is momentarily pressed, an image signal corresponding to the still image at that moment is used as image data, and when the release switch R is pressed for a certain period, it corresponds to a moving image during that period. Assume that an image signal is image data.

  As shown in FIG. 2, the imaging unit 100 including the imaging element includes a lens 42 on the back side opposite to the front side on which the display screen 174 and the operation button group 16 are provided, and the camera mode is set. In this case, since the photographed image is formed on the image sensor 43 such as a CCD through the lens 42, an image signal output therefrom can be acquired. Although not shown, the lens 42 is configured to be driven in the optical axis direction so as to be in a focused position. In the camera mode, the imaging unit 100 according to this embodiment performs an imaging process by operating the release switch R in the operation button group 16 and performs an imaging process, and image data (first image) obtained by the imaging process is performed. Image data) is stored in the FROM 51 or the memory card 7 selected by the card controller 52. For example, when the release switch R is momentarily pressed, an image signal corresponding to the still image at that moment is used as image data, and when the release switch R is pressed for a certain period, it corresponds to a moving image during that period. Assume that an image signal is image data. Here, the image processing refers to, for example, converting an image signal obtained from the imaging unit 100 or the tuner unit 50 into a video signal composed of luminance and color difference, and performing compression processing using a standardized compression method. A process for obtaining data. Note that the image processing is not limited to this method, and in short, in order to store in the storage unit, data obtained by using some processing on the image signal is handled as image data.

  The detachable FROM 51 and the detachable memory card 7 are for storing image data corresponding to an image captured by the imaging unit 100 and image data corresponding to an image based on a television signal. In addition, the control unit 8 has a work memory. The directory structure described below may be formed in the FROM 51, but will be described assuming that it is generally formed in the memory card 7 having a larger capacity.

  FIG. 3 is a diagram showing an example of a directory structure formed in the memory card 7. In FIG. 3, a “DCIM” directory and a “TVIM” directory are provided in parallel below the “ROOT” directory. Below the “DCIM” directory, the image data relating to the image captured by the image capturing unit 100 is a file such as “IMG... JPG” for a still image and “MOV. Named and stored. On the other hand, in the lower layer of the “TVIM” directory, image data related to an image based on a television signal is “IMG... TV” for a still image and “MOV. A file name is assigned and stored. The file name is not limited to the above.

  Here, in the example shown in FIG. 3, the file identifier (.JPG or AVI) of the image data (first image data) related to the image captured by the imaging unit 100 and the image data related to the image based on the television signal. The file identifier (.TV or TVM) of (second image data) is made different. The file name is determined so that the last four digits are in ascending order in the recording order.

  FIG. 4 is a schematic diagram showing the contents of a file related to image data according to a certain standard. The image data includes an incidental information part including incidental information, thumbnail image data, and main image data. The accompanying information includes a file name, shooting conditions, information indicating the origin called a maker note, and the like. In the present embodiment, the file name related to the image data related to the image captured by the image capturing unit 100 is recorded as “IMG0001.JPG” for a still image, for example, and “MOV0004.AVI” for a moving image. The recorded manufacturer note is also recorded as, for example, “Konica Minolta mobile phone”. On the other hand, the file name relating to the image data relating to the image based on the image signal is recorded as “IMG0001.TV” or the like in the case of a still image, and as “TVM0004.AVI” or the like in the case of a moving image. For example, “TV broadcast” is recorded.

  FIG. 5 is a flowchart showing another example of the operation of the mobile phone T with an imaging function according to the present embodiment. Here, the user may want to send an e-mail attached with an image stored in the memory card 7. However, if the user can do this without limitation, the copyright holder cannot make a profit. Therefore, image data based on image signals cannot be attached to e-mails in principle. However, for example, the user pays the copyright holder side (including deduction from the charge deduction account of the mobile phone). When encryption information (for example, a combination of numbers) is assigned, the limitation is removed by inputting the encryption information using the operation button group 16.

  First, in step S201, the user checks an image stored in the memory card 7 on the display screen 174 after a predetermined input such as a mail destination, and selects an image to be transmitted. Then, the control device 8 reads the file name or maker note from the supplementary information in the image data corresponding to the selected image in step S202, and determines that it is an image photographed by the imaging unit 100. In step S203, the image data is transmitted to the other party as an email attachment.

  On the other hand, when it is determined from the read file name or manufacturer note that the image is an image extracted from the television signal, the control unit 8 waits for input of encryption information. In step S204, when the user operates the operation button group 16 to input a combination of numbers, the control unit 8 authenticates the input number in step S205, and the correct combination of numbers is obtained. If it is determined that it has been input, the control unit 8 transmits the image data to the other party as an email attachment in step S203.

  On the other hand, when it is determined that the correct combination of numbers has not been input, the control unit 8 causes the display screen 174 to display a warning message such as “This image cannot be transmitted” and not attach an email in step S206. To process.

  Since the memory card 7 is detachable, it can be directly accessed from a personal computer by using a memory card reader after being removed from the mobile phone, and can be read out with the directory structure shown in FIG. At this time, if the predetermined software is installed in the personal computer in advance, the directory of the file related to the image data based on the image pickup unit and the directory of the file related to the image data based on the television signal are handled differently. It can be. For example, copying and transfer of files in the “TVIM” directory can be prohibited. In addition, as a hidden file, a file in the “TVIM” directory may not be displayed on the display of the personal computer. As described above, image data may be distinguished based on individual file names and the like.

  FIG. 6 is a diagram showing another example of the directory structure formed in the memory card 7. In FIG. 6, the identifier of the file related to the image data related to the image captured by the imaging unit 100 and the identifier of the file related to the image data related to the image based on the television signal are the same (.JPG or AVI). The file name related to the image data relating to the image based on the television signal is “TVI0001˜” for the still image and “TVM0004˜” for the moving image, while the image data relating to the image captured by the image capturing unit 100. The files can be distinguished from each other by differentiating them from the file, the still image “IMG0001˜” or the moving image “MOV0004˜”.

  According to the present embodiment, it is possible to protect the copyright holder's right over the broadcasted video by preventing illegal distribution or copying while securing the convenience of the user of the mobile phone.

  FIG. 7 is a diagram showing another example of the directory structure formed in the memory card 7. 7, in the directory structure of FIG. 6, a file related to image data based on imaging and a file related to image data based on a television signal are mixedly stored under the root directory. Even in such a case, it is possible to identify whether the file is a file related to image data based on imaging or a file related to image data related to an image based on a television signal from the file name.

  The present invention has been described above with reference to the embodiments. However, the present invention should not be construed as being limited to the above-described embodiments, and can be modified or improved as appropriate. For example, the electronic device is not limited to a mobile phone but also includes a PDA (Personal Digital (Data) Assistants). In addition, the file format of image data related to an image based on a television signal can be distinguished from the image data file based on imaging by making the format different from the so-called Exif format.
