Abstract

PROBLEM TO BE SOLVED: To provide an imaging device that, when selecting a transmission image, is capable of facilitating selection of the transmission image by not displaying an image not to be transmitted.SOLUTION: An imaging device capable of transmitting/receiving an image compares identification information of a connection destination device with identification information of a transmission source device added to the image, and when they match each other, performs control so that the image is not reproduced.

Description

  The present invention relates to a control device and the like related to an imaging device such as a digital camera, and more particularly to image display in image transmission / reception between photographing devices and execution control during transmission / reception.

  Conventionally, in image transmission / reception between imaging devices such as digital cameras, the transmission side device manages the identification number of the reception side device and the transmitted image using a management file, and manages the presence / absence of untransferred images. An imaging apparatus that performs control that does not transmit twice is realized (see Patent Document 1).

  In addition, an image pickup apparatus that stores the image transmission source and performs control so that the image is not transmitted to the transmission source is realized by adding the identification information of the transmission side device to the file name of the image received from another apparatus. (See Patent Document 2).

JP 2005-51682 A JP 2006-079551 A

  However, if the transmission information is managed as a separate file, the image cannot be managed by a device capable of directly writing the image on a storage medium such as a personal computer. In addition, if a character is added to the original file name of a copy of an image taken by another device on a recording medium, the image does not conform to the DCF standard, and thus an image such as a reproduction cannot be processed in an imaging device such as a digital camera.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an imaging apparatus that makes it easy to select a transmission image by not displaying an image that is not transmitted when the transmission image is selected.

In order to achieve the above object, the present invention provides:
In an imaging device capable of transmitting and receiving images,
When the identification information of the connection destination device matches the identification information of the transmission source device added to the image,
Control is performed not to reproduce the image.

  According to the present invention, the camera identification number of the transmission source is written in the image, and the identification number is confirmed at the time of transmission, so that the image sent from the other party can be prevented from being sent back.

[Example 1]
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram illustrating a configuration example of an information processing system in the present embodiment.

  In FIG. 1, the imaging device 100 is connected to the imaging device 400 via a network 500. In this embodiment, an example in which a wireless LAN is used as the network 500 will be described. Note that the network that can be used for the network 500 is not limited to a wireless LAN. For example, the network 500 may be a network using infrared communication or a network using BlueTooth (registered trademark). Alternatively, another wired network may be used.

  First, the imaging device 100 will be described. FIG. 2 shows a configuration of the imaging apparatus 100. In this embodiment, a digital camera that is an example of the imaging apparatus 100 will be described. Note that the imaging apparatus 100 is not limited to a digital camera. For example, it may be a personal computer, a mobile phone, or a so-called tablet device.

  The control unit 101 controls each unit of the imaging apparatus 100 according to an input signal and a program described later. Note that instead of the control unit 101 controlling the entire apparatus, a plurality of hardware may share the processing to control the entire apparatus. The imaging apparatus 100 according to the present exemplary embodiment can acquire image data by the control unit 101 controlling an imaging unit 102 described later. Further, it has a function of displaying a normal menu screen and an image reproduction screen on the display unit 106 by operating the operation unit 105.

  The normal menu screen is a screen that the control unit 101 displays on the display unit 106 when a menu button is pressed on the operation unit 105 to be described later. The normal menu screen includes selection of the size of image data to be acquired and communication. There are menus for selecting functions, setting the brightness of the display unit 106, selecting a language to be displayed, and the like, and a screen that allows the user to change or execute the function settings of the imaging apparatus 100 by operating the operation unit 105 It is. In this embodiment, the communication function can be set on the menu screen. The image playback screen is a screen that the control unit 101 displays on the display unit 106 when a playback button is pressed on the operation unit 105 described later, and is a screen on which image data can be viewed using the display unit 106 described later. It is. The imaging unit 102 performs an imaging process.

The imaging process is a process of converting subject light imaged by a lens included in the imaging unit 102 into an electrical signal, performing noise reduction processing, and outputting digital data as image data. The captured image data is stored in the buffer memory, and then a predetermined calculation is performed by the control unit 101 and recorded on the recording medium 110. Further, when image data is recorded on the recording medium 110 by the imaging process, the initial value of the identification information is set by writing the identification information of the own device.
The non-volatile memory 103 is an electrically erasable / recordable non-volatile memory, and stores a program to be described later executed by the control unit 101.

  The work memory 104 is used as a buffer memory that temporarily holds image data picked up by the image pickup unit 102, an image display memory of the display unit 106, and a work area of the control unit 101.

  The operation unit 105 is used by the user to instruct the operation of the imaging apparatus 100. The operation unit 105 includes, for example, a power button for instructing power ON / OFF of the imaging apparatus 100 and a release switch for receiving an instruction to perform imaging processing. Further, it includes an operation member such as a menu button for displaying the above-described normal menu screen, a playback button for displaying the above-described image playback screen, a cross key for receiving an operation during screen display, and a touch panel.

  The display unit 106 displays a through image at the time of imaging, displays captured image data, and displays characters for interactive operation. In the present embodiment, the control unit 101 controls the image data output from the imaging unit 102 to be continuously displayed on the display unit 106 while sequentially updating as a through image. Thereby, the display unit 106 sequentially displays the image data captured by the imaging unit 102 in real time. Note that the display unit 106 does not need to be included in the imaging apparatus 100, and the imaging apparatus 100 may be connected to the display unit 106 and has at least a display control function for controlling display on the display unit 106.

  The communication unit 109 is a connection unit for communicating with other devices. The imaging apparatus 100 according to the present exemplary embodiment can exchange data with the imaging apparatus 400 described later via the communication unit 109. In the present embodiment, the communication unit 109 is a wireless communication unit, and the control unit 101 can perform wireless communication with the imaging device 400 via an antenna. The communication unit 109 is also used when the imaging apparatus 100 is connected to a network such as the Internet.

  The recording medium 110 can record image data output from the imaging unit 102 and subject information acquired through the communication unit 109. In this embodiment, image data will be described as an example of handling in the form of an EXIF JPEG image. In the EXIF JPEG image format, thumbnails and attribute information (metadata) can be recorded in the header of the image data. The recording medium 110 may be configured to be detachable from the imaging apparatus 100 or may be built in the imaging apparatus 100. That is, the imaging apparatus 100 only needs to have at least a means for accessing the recording medium 110.

  The above is the description of the imaging device 100. Next, the imaging apparatus 400 that can communicate with the imaging apparatus 100 will be described. In this embodiment, a digital camera that is an example of the imaging apparatus 400 will be described. Note that the imaging apparatus 400 is not limited to a digital camera. For example, it may be a personal computer, a mobile phone, or a so-called tablet device. Since the imaging apparatus 400 has the same configuration as that of the imaging apparatus 100, description thereof is omitted.

  The above is the description of the imaging device 400 that can communicate with the imaging device 100.

  Next, communication functions provided in the imaging apparatus 100 will be described. The imaging apparatus 100 includes a camera connection mode that is a function of connecting to the imaging apparatus 400 via the network 500.

  While the image capturing apparatus 100 is connected to the image capturing apparatus 400 in the camera connection mode, the image capturing apparatus 100 can function to select and transmit image data recorded on the recording medium 110 using the PTP protocol. Further, while the image capturing apparatus 100 and the image capturing apparatus 400 are connected in the camera connection mode, it is possible to receive image data using the PTP protocol and write the image data on the recording medium 110. When either one of the imaging apparatus 100 transmits image data to the imaging apparatus 100, the other is receiving image data, and the image cannot be transmitted during that time.

  At that time, display indicating that image data is being transmitted is displayed on one display unit 106, and display indicating that image data is being received is displayed on the other display unit 106. While the imaging apparatus 100 is connected to the imaging apparatus 400 in the camera connection mode, operations other than transmission and reception of image data cannot be performed. This is because when the camera connection mode is transmitted and received in the background so that the user can perform other operations such as shooting, the image is captured to the recording medium 110 while the image data is being received. This is because complicated control such as avoiding contention in the writing process and avoiding contention to the communication unit 109 due to execution of the transmission process during reception is necessary, thereby simplifying the control.

  The above is the description of the communication function that the imaging apparatus 100 includes.

  Next, a playback control method during connection in the camera connection mode will be described based on the flowchart of FIG. When the connection process in the camera connection mode is completed, the control unit 101 starts an image display process.

  In step S301, the identification number of the connection destination camera is stored, and the process proceeds to step S302. In step S302, it is determined whether there is a reproduction candidate image. For example, if there is no image on the recording medium 110, it means that there is no reproduction candidate image. In addition, even if the image to be reproduced is not found even if the image on the recording medium 110 is checked once in the flowchart of FIG. 3, there is no reproduction candidate image. If applicable in step S302, the process proceeds to step S307, a message indicating that there is no image to be reproduced is displayed on the display unit 106, and the process ends. On the other hand, if not applicable, the process proceeds to step S303.

  In step S303, when the reproduction candidate identification number is acquired, the process proceeds to step S304. In step S304, the identification number of the connection destination camera is compared with the identification number of the reproduction candidate. That is, it is confirmed that the reproduction candidate image is not an image received from the connection destination. If they do not match, it is not a received image from the connection destination, so the process advances to step S305 to display a reproduction candidate image on the display unit 106, and the process ends. On the other hand, if they match in step S304, since the received image is from the connection destination, the process proceeds to S306.

  In step S306, the reproduction candidate is changed. For example, the next reproduction candidate image is set as a new reproduction candidate, and the process proceeds to step S302.

  The flowchart of FIG. 3 is executed not only when the connection process in the camera connection mode is completed but also when the image feed is operated by the operation of the operation unit 105.

  Next, a transmission control method in the camera connection mode will be described based on the flowchart of FIG.

  When the image displayed on the display unit 106 in S305 is instructed to be transmitted by operating the operation unit 105, the control unit 101 starts an image transmission process.

  In step S401, the identification number of the image to be transmitted is changed to the identification number of the own device, the image is transmitted in step S402, and the process ends.

  As described above, in this embodiment, control is performed so that images received from the connection destination are not displayed during playback when connected in the camera connection mode. Thus, the user can instruct transmission of an image to be transmitted without transmitting the received image.

[Example 2]
In the present embodiment, an example will be described in which all images are displayed during reproduction when connected in the camera connection mode, and an image received from the connection destination cannot be transmitted. The configuration of the present embodiment is the same as that of the first embodiment in both FIG. 1 and FIG.

  Further, since the playback method in the camera connection mode is the same as the normal playback, the description thereof is omitted.

  A transmission control method in the camera connection mode will be described based on the flowchart of FIG.

  When transmission of an image displayed on the display unit 106 is instructed by an operation of the operation unit 105, the control unit 101 starts an image transmission process.

  In step S501, the identification number of the connection destination camera is stored, and the process proceeds to step S502.

  In step S502, the identification number of the reproduced image is acquired, and the process proceeds to step S503.

  In step S503, the identification number of the connection destination camera is compared with the identification number of the reproduced image. That is, it is confirmed that the image being reproduced is not an image received from the connection destination. If they do not match, it is not a received image from the connection destination, and the process advances to step S504. On the other hand, if they match in step S503, the received image is from the connection destination, so the process proceeds to S506, a warning is displayed on the display unit 106, and the process ends.

  In step S504, the identification number of the image to be transmitted is changed to the identification number of the own device, the image is transmitted in step S505, and the process ends.

  As described above, in the present embodiment, all images are displayed during playback when connected in the camera connection mode, and control is performed so that images received from the connection destination cannot be transmitted during transmission. Accordingly, the user can instruct transmission of an image to be transmitted without erroneously transmitting the received image.

[Example 3]
In the first and second embodiments, the example in which the determination process is performed on the transmission side has been described. In the present embodiment, an example in which the determination process is performed on the reception side will be described. The configuration of the present embodiment is the same as that of the first embodiment in both FIG. 1 and FIG.

  Further, since the playback method in the camera connection mode is the same as the normal playback, the description thereof is omitted.

  A reception control method in the camera connection mode will be described with reference to the flowchart of FIG.

  When the control unit 101 detects an image reception request, it starts an image reception process.

  In step S601, the identification number of the own device is acquired, and the process proceeds to step S602.

  In step S602, information on an image to be received is received, an identification number is acquired, and the process proceeds to step S603.

  In step S603, the identification number of the own apparatus is compared with the identification number of the received image. That is, it is confirmed that the image to be received is not an image transmitted from the device in the past. If they do not match, the image has not been transmitted from the device in the past, and the process advances to step S604. On the other hand, if they match in step S603, since the image has been transmitted from the apparatus in the past, the process advances to step S607 to cancel reception, and the process ends.

  In step S604, an image is received. In step S605, a connection destination identification number is acquired. In step S606, the connection destination identification number acquired in step S605 is written in the received image, and the process ends.

  As described above, in this embodiment, control is performed so that the image receiving side does not receive the image in the camera connection mode. As a result, the user can avoid receiving an extra image on the receiving side.
