DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments using a digital camera or the like will be described below with reference to the drawings, to an imaging device to which the present invention is applied and a method for controlling the imaging device. The camera according to the first embodiment of the present invention has a live view function in which a subject image is photoelectrically converted by an image pickup device, and the acquired image data is displayed as a moving image in real time. The image data can be recorded on a recording medium. In addition, this camera can be connected to a server through a network, and the state of the viewer's image reproduction device can be detected therefrom and fed back to the camera.

FIG. 1 is a block diagram of a digital camera and its surroundings according to the first embodiment of the present invention. A camera 100 used by a user includes a photographic lens 2, an AF (autofocus) control unit 2a, an aperture 2b, an aperture control unit 2c, an image sensor 3, and an analog front end (hereinafter referred to as AFE) unit 4. Yes. The taking lens 2 has a focus lens inside, and forms an image of the incident subject 20 on the image sensor 3.

The AF control unit 2a performs image processing in an image processing unit 5 to be described later, detects an in-focus position of the photographic lens 2, detects it by a so-called hill-climbing method, drives the focus lens, and moves it to the in-focus position. Note that the hill-climbing method is a method for detecting the in-focus position (focus position) from the contrast signal peak of the photographed image. It may be replaced. When the in-focus position is reached by AF, the distance can be determined by detecting the photographing lens 2 at this time. In this case, when the photographing lens 2 is a zoom lens, the distance is determined in consideration of the zoom position and the like.

A diaphragm 2b that provides the effects of a shutter and a diaphragm is provided in or near the photographing lens 2. The diaphragm 2b is opened to a predetermined aperture at the time of photographing, and is closed when the exposure is finished to finish the exposure. The aperture control unit 2c drives the aperture 2b to set the aperture diameter. By changing the aperture, the depth of field of the lens changes, so you can change the expression by adjusting the blurring of the background, etc. Can do. The image pickup device 3 is a CCD or CMOS sensor having a large number of light receiving surfaces (pixels), and receives an image from the subject 20 via the photographing lens 2 and converts it into an image signal.

The analog front end (AFE) unit 4 includes analog-to-digital conversion (AD) means, and converts a signal from the image sensor 3 into a digital signal. The AFE unit 4 performs various processes on the image signal output from the image sensor 3. The AFE unit 4 is also provided with a function of reading several pixels of the image pickup device 3 together and reading them together. For example, when the signal level of each pixel is small, such as 4 pixels (2 × 2) and 9 pixels (3 × 3), several pixel signals can be added to improve the S / N. Sensitivity can also be increased.

Sensitivity can be increased by such processing, and it is possible to devise photography such as increasing the shutter speed. When the shutter speed is high, it is possible to shoot as if the moving subject is stopped. In addition, camera shake and the like can be prevented.

The AFE unit 4 has a function of selecting signals output from the image sensor 3 and can extract image data in a limited range from the light receiving range. In general, when pixel signals thinned out from the pixels of the image sensor 3 are extracted, high-speed reading is possible. Thus, the image signal for composition confirmation is processed at high speed by the image processing unit 5 and displayed on the display panel 8 via the display control unit 8a, thereby enabling framing.

The output of the AFE unit 4 is connected to the image processing unit 5. The image processing unit 5 corrects the color, gradation, and sharpness of the input signal. Further, it has an intensifying unit that amplifies the image signal obtained from the image sensor 3 to a predetermined level and sets the correct gray level and the correct gray level. This is a digital operation so that the digitized signal level becomes a predetermined level. In addition, the image processing unit 5 includes a resizing unit that processes a signal from the image sensor 3 to a size that can be displayed on the display panel 8 so that a live image can be displayed on the display unit in real time. By this function, an image incident on the image sensor can be confirmed prior to shooting, and the timing and photo opportunity at the time of shooting can be determined while viewing this.

In addition, the image processing unit 5 has an image determination function for determining characteristics of an image input from the image sensor using the signal of the image processing unit 5. As the image determination function, a face detection unit 5a for determining a part of a person's face such as eyes and mouth from contour information obtained by processing image information, and using this face detection unit 4a to express facial expressions such as a face. It has a facial expression determination unit 5b for determining and a personal authentication unit 5d for identifying an individual's face and authenticating the individual. The image processing function further includes a distance determination unit 5c that determines the distance of the subject by determining the contrast of the signal level of the image. The image processing unit 5 and its peripheral auxiliary unit are also used to adjust the appearance of the captured image in cooperation with the MPU 1.

In this way, the image processing unit 5 and the peripheral auxiliary units (the face detection unit 5a, the facial expression determination unit 5b, the personal authentication unit 5d, etc.) determine what kind of photograph the user is going to take when taking a picture. Further, it is used to determine the preference of the viewer who sees the picture and optimize the shooting control.

The camera 100 includes a compression unit 6, a recording unit 9a, a recording medium 9, a transmission / reception unit 9c, a transmission destination state determination & database (DB) 9d, a transmission setting unit 9e, a display panel 8, a display control unit 8a, and a multi-image processing unit. 8b is provided. The compression unit 6 compresses the signal output from the image processing unit 5 at the time of shooting. The compression unit 6 includes MPEG (Moving Picture Experts Group) 4 and H.264. A still image compression unit such as a compression unit for moving images including a compression core unit such as H.264 and a JPEG (Joint Photographic Experts Group) core unit is provided. The compression unit 6 also performs image expansion when reproducing an image recorded on the recording medium 9 on the display panel 8.

The recording unit 9 a records the compressed image signal on the recording medium 9. The recording medium 9 is a storage recording medium that can be attached to and detached from the camera. In recording an image signal, time information when a photograph is taken may also be recorded. The shooting time information is measured by a clock unit 1t in the MPU 1 described later, and the MPU 1 associates with the image.

The captured image data recorded on the media 9 or the recording unit 9a is transferred to other devices such as the server 33 that manages images via the communication network 32 such as the Internet, a mobile phone network, and a telephone line by the transmission / reception unit 9c. be able to. The transmission / reception unit 9c is connected to the transmission setting unit 9e, and the transmission setting unit 9e is a designation unit that designates a transmission destination when transmitting an image. The captured image can be sent immediately to a designated destination. At this time, the viewer's preference information may be acquired.

The display panel 8 is composed of, for example, a liquid crystal, an organic EL, or the like, and displays a subject image as a through image (also referred to as a live view display) for observation at the time of photographing, and reproduces and displays an expanded recorded image at the time of reproduction.

The display control unit 8 a controls display on the display panel 8. The multi-image processing unit 8b is a control unit for displaying a plurality of images on the display panel 8. With this multi-image processing unit 8b, it is possible to display characters of the address of the transmission destination and various warnings on the photographed image or the photographed image. The display panel 8 displays a list of images that have been shot and transmitted, and from there, an image to be uploaded to a blog service or the like operated by the server 33, or a layout for uploading and displaying the image on a blog can be selected. You may do it. In addition, the multi-screen display function 8b makes it possible to display various auxiliary displays such as information for assisting shooting and examples of images that the viewer likes.

Further, the display on the display panel 8 is displayed by switching the aspect ratio according to the screen of the transmission device of the transmission destination based on the output of the transmission destination state determination & database (DB) 9d, and shooting is also performed in this aspect. I do it in ratio. For example, when the playback device of the transmission destination has a 16: 9 screen, it takes a picture with that aspect ratio, and when it has a 4: 3 screen, it takes a picture with that aspect ratio and displays the live view on the display panel 8. Displays a frame according to the aspect ratio and shoots only within that range.

The transmission destination state determination & database (DB) 9d is a database that records a tendency such as what device the viewer designated as the transmission destination views. In the present embodiment, based on the information in this database, it is determined whether or not viewing is possible with the playback device at the transmission destination, and the photographer is prompted to take a picture. The transmission destination state determination & database 9d acquires information on the transmission destination state from the server 33 described later.

The camera 100 is provided with an auxiliary light emitting unit 11, a microphone 12, an MPU (Micro Processing Unit) 1, a release switch 1a, a mode switch 1b, and another switch 1c. The auxiliary light emitting unit 11 includes a white LED and a Xe discharge light emitting tube, and the amount of light can be controlled by the amount of current. Depending on the situation, the subject 20 is irradiated with light to prevent lack of brightness and uneven brightness. The microphone 12 collects sound, takes in surrounding audio information, compresses the audio by the compression unit 6, and records it on the recording medium 9 in association with the image data by the recording unit 9.

The MPU 1 is a control unit that controls the entire camera. A release switch 1a, a mode switch 1b, another switch 1c, and a ROM (not shown) storing a program and the like are connected to the MPU 1. A clock unit 1t for detecting the date and time is provided in the MPU 1, and the shooting date and time of the photo is detected and associated with the captured image. Note that the switches 1b and 1c are generically displayed switches, and are actually composed of a large number of switch groups. The MPU 1 is connected to a position determination unit 1d, and the position determination unit 1 detects a position by GPS or the like. Using this detected position, the shooting position at the time of shooting and the above shooting date and time are recorded on the medium 9 together with the image data.

Each switch 1a-1c detects a user's operation, and notifies the result to MPU1 which is a calculation control means consisting of a microcontroller. The MPU 1 switches the operation according to the operation of these switches. Also, the MPU 1 performs a shooting control function for controlling the AF control unit 2a, the aperture control unit 2c, and the like, and a recording control function for recording the acquired image data / acquired audio data in the recording unit 9a and the recording medium 9 at the time of shooting.

The camera 100 configured as described above is connected to a server 33 via a communication network 32, and a personal computer (PC) 34 owned by the user 31 can be connected to the server 33. The server 33 can be connected to a playback device such as a large screen television 34a or a mobile phone 34b. The server 33 determines the usage status of these playback devices, and the determination result is transmitted via the communication network 32. It can be transmitted to the camera 100. The configuration of the server 33 and its peripheral circuits will be described later with reference to FIG.

Next, the operation of the camera configured as described above will be described with reference to the drawings. FIG. 2 is a diagram showing a typical usage state. FIG. 2 shows an example of a grandmother 31 (viewer) who is looking forward to the growth of grandchildren. The grandmother (viewer) 31 looks forward to seeing the grandchild's photos. I'm looking forward to receiving it, but depending on the situation, the image may not be easily seen. For example, when watching a large television (TV) 34a, even if an image is sent to the mobile phone 34b, the power of the mobile phone 34b is turned off or the ring tone is not noticed, and the user keeps going. There are also many. Also, it is nice to watch on a large screen television (TV) 34a because it looks powerful and large, but when you go out you can only watch it on your mobile phone 34b.

In the transmission destination state determination & database (DB) 9d described above, information on playback devices used by the viewer as shown in FIG. 3 is recorded. As will be described later, in the flowchart of FIG. 4, display and warning control are performed so as to determine the device environment that can be used by the transmission partner when using the camera 100 and to prompt the user of the camera 100 to perform shooting suitable for the viewing device of the transmission partner. Is performed by the camera 100. As a result, an image that is easy for the viewer to view can be taken and sent in a timely manner.

The large-screen television (TV) 34a and the mobile phone 34b have different screen sizes and resolutions, and different images suitable for reproduction, such as whether audio can be effectively reproduced. Therefore, in this description, it is assumed that the grandmother (viewer) 31 is always watching the large screen television (TV) 34, and first, the home appliance network determines whether the large screen television (TV) 34a is on. If it is turned on, it captures and transmits a moving image that can withstand a large screen and has a sound recorded. Such a determination result of the playback device status is displayed on the display unit on the back of the camera 100 (see FIG. 2).

However, when the grandmother (viewer) 31 goes out, the power of the large-screen television (TV) 34a is turned off. Therefore, the power-off is determined through the home appliance network, and in that case, an image suitable for the mobile phone 34b (for example, VGA (Video Graphics Array) still image) is transmitted to the mobile phone 34b. Of course, if the grandmother (viewer) 31 has many opportunities to go out, the priority order is reversed, and the power supply of the mobile phone 34b is first determined to increase the priority of image transmission to the mobile phone 34b. You may make it do.

When the mobile phone 34b is turned off, the power source of the large screen television (TV) 34a is determined. If it is turned on, an image to be transmitted to the large screen television (TV) 34a may be taken. . When both of them are off, we will give up sending them on the spot and send them to the mobile phone later, so that the VGA still image is taken and the image is held in the camera.

In this way, control is performed according to the priority order of the device information used by the viewer shown in FIG. 3, but the user is other than the grandmother, and FIG. 3 shows an example of the device used by the grandfather. Here, the grandfather likes to watch on a large screen because his eyes are bad. For example, when both the mobile phone and the large-screen TV (TV) are turned on, the large-screen TV (TV) 34a having a large screen is used. Expect to send to.

If the grandfather uses a personal computer (PC) to enjoy the Internet and mail, even if the large-screen TV (TV) 34a is off, it is displayed on the personal computer (PC) having the next largest screen. I want it. When such a viewer is assumed, the power supply of the personal computer (PC) is checked before the power supply of the mobile phone 34b is checked. When the personal computer (PC) is also turned off, an image is transmitted to the mobile phone 34b.

Further, as can be seen on the screen of a personal computer (PC), the image may be recorded on a server that provides an image storage service or a server 35 of a home server (see FIG. 5). A user of a personal computer (PC) can easily find and view an image recorded in such a place. Therefore, since the image is stored on the mobile phone 34b, a prompting display that prompts browsing is performed. Although lacking in immediacy, it is possible to view images on the large screen that my grandfather likes.

Next, the operation of this embodiment will be described using the flowchart shown in FIG. When the main routine for image shooting is entered, it is first determined whether or not the camera is in shooting mode (S0). If shooting is performed using the camera 100, the shooting mode is determined. For example, if shooting using the camera 100 is not performed such as transmission setting, playback mode, transmission mode, etc., the non-shooting mode is set as step S1. Proceed to

Subsequently, it is determined whether or not transmission is set (S1). This is a determination as to whether or not to perform presetting when transmitting image data to the viewer (eg, grandmother, grandfather) 31. As a result of the determination, if transmission setting is to be performed, a sender is selected from the transmission destinations recorded in the transmission destination state determination & database (DB) 9d (S2), and the transmission destination state determination & database (DB) 9d The recorded contents are referred to (S3). That is, reference is made to the priority and mode / image size of the playback device.

Next, based on the transmission destination state determination & reference result of the database (DB) 9d, it is determined whether or not the power of the device with the higher priority is turned on (S4). In this determination, the power supply state may be detected directly if communication between the camera 100 and the playback device can be performed, but if the playback device is connected to the server 33 via the communication network 32, A power state is detected through the server 33. In the example shown in FIG. 3, if the grandmother is selected as the transmission destination, the high-priority device is the large-screen television (TV) 34a. In step S4, the large-screen television (TV) 34a is It is determined whether or not the power is currently on.

If the result of determination in step S4 is that the power is on, the type of playback device is displayed and a shooting mode is instructed according to the recorded contents of the destination status determination & database (DB) 9d (S5). In other words, the transmission destination state determination & database (DB) 9d stores the optimum mode and image size according to the device. In the case of a grandmother, for example, in the case of a large screen television (TV) 34a, Select HD (high definition size) for the moving image. The shooting mode and the like are automatically set, but may be manually set.

On the other hand, if the result of determination in step S4 is that the device with the higher priority is turned off, the device with the higher priority will not be able to view the image immediately, so the device with the next highest priority is searched. (S6).

Next, it is determined whether or not the device has been searched as a result of the device search in step S6 (S7). As a result of the determination, if there is a device with the next highest priority, the process returns to step S4 to search whether the device is powered on. In this way, it is detected whether or not the power is turned on in order of priority, and if the device is turned on, a shooting instruction is issued in a shooting mode suitable for the device. This photographing instruction is performed by character display or icon display, and the aspect ratio of the screen is performed by changing the effective area 8c (see FIG. 5) of the display screen of the display panel 8.

If it is detected in step S7 that all the playback devices are not turned on, the specific shooting mode is set (S8). That is, in this case, a shooting mode instruction is performed assuming a default device. When there is no target device, the shooting mode assuming the default device is a shooting mode on the premise that recording in the camera or recording to the image storage server is performed.

When the specific shooting mode setting is finished in step S8 or the shooting mode instruction in step S5 is finished, it is next determined whether or not the mode is another mode (S9). This other mode is a mode other than the destination setting, for example, a playback mode or a transmission mode. If any other mode is set, that mode is executed (S11). If no other mode is set, or when the execution of the other mode ends, the process returns and executes from step S0.

If the result of determination in step S0 is that the camera is in the shooting mode, live view display for displaying the image data from the image sensor 3 on the display panel 8 is performed, and at this time, it is necessary for shooting. If, for example, the shutter speed is displayed or if transmission is set, the destination device is also displayed on the display panel 8 (S21).

Next, it is determined whether or not the corresponding image is taken (S22). That is, it is determined whether the shooting is the shooting with the transmission destination set in step S1 (corresponding image shooting, processing in step S22 and subsequent steps) or other normal shooting (processing in step S31 and lower steps). This can be set, for example, by operating a button on the back of the camera. If shooting is performed assuming a transmission destination by button operation, shooting is performed in a mode suitable for the transmission destination. However, in the case of shooting without this operation, the shooting sequence is the same as that of a general camera that records an image in the camera without being aware of transmission.

As a result of the determination in step S22, if it is determined that the corresponding image is not captured, it is next determined whether or not it is other image capturing, that is, whether or not normal image capturing other than the corresponding image capturing is performed ( S31). As a result of the determination, if it is another shooting, or if it is determined that the subject is not a predetermined subject as a result of the determination in step S23, the release button is fully pressed to determine whether or not it is a release operation (S32). ). If the release button is fully pressed as a result of the determination, a shooting operation is performed and normal image data is recorded on the recording medium 9 (S33).

On the other hand, if the result of determination in step S22 is that the image has been taken and there is a destination designation, a live view display that displays the image from the image sensor 3 on the display panel 8 and a person who wants to send a photo If there is device information for viewing (such as the type of device such as a large-screen television, shooting mode, image size, etc.), it is also displayed on the display panel 8 together. Subsequently, it is determined whether or not the current image is a subject that the viewer wants to see, in the example of FIG. 3, whether or not it is a grandmother of the grandmother (S23). This determination is made based on detection outputs from the face detection unit 5a, the facial expression determination unit 5b, the personal authentication unit 5d, and the like.

If the result of determination in step S23 is that the predetermined subject has been requested, the predetermined mode is set (S24). That is, shooting is performed in a mode (see FIG. 3) suitable for shooting and viewing according to the shooting mode stored in the transmission destination state determination & database (DB) 9d. In this step, there is a case where transmission is set in step S1 and, for example, even if it is intended to take a picture of the grandchild, it may be desired to take another subject that has entered the eyes. The image taken in such a case does not need to be transmitted, so the determination in step S23 is made, but it can be omitted.

Once the predetermined mode is set, it is next determined whether or not a release operation has been performed (S25). If the result of determination is that a release operation has been performed, shooting is performed and the captured image data is transmitted (S26). This image transmission is transmitted to a person who wants to show through the transmission / reception unit 9c by operating the transmission setting unit 9e according to the destination device information in the transmission destination state determination & database (DB) 9d.

Note that when all the transmission destination devices are turned off and cannot be transmitted, they are recorded in the memory in the camera 100 without being transmitted, or temporarily stored in the transmission recording unit in the server 33. When shooting in a special mode, tips for shooting may be displayed in step S22 to assist shooting. If it is determined in step S31 that no other image is taken and no release operation is performed in step S32, the process returns.

As described above, in the flowchart of the camera according to the first embodiment of the present invention, the transmission destination is preset based on the transmission destination stored in the transmission destination state determination & database (DB) 9d. (S1-S8). Further, when entering the shooting mode, it is determined whether or not the corresponding image to be transmitted to the transmission destination is shot, and if it is detected as a predetermined subject, it is stored in the transmission destination state determination & database (DB) 9d. Shooting is performed in a predetermined mode. For this reason, it is possible to easily take a photograph suitable for the playback device of the viewer.

Next, the server 33 for acquiring information about the playback device of the viewer will be described with reference to FIG. FIG. 5 is a block diagram showing the server 33 and its surroundings. In the server 33, a communication unit 33a for communicating with the camera 100 is provided. A diary / image recording unit 33b for recording images and comments received by the communication unit 33a is provided. The calendar unit 33i stores calendar information such as events. The display control unit 33c performs display control of content such as images recorded in the diary / image recording unit 33b when accessed from a personal computer.

In addition, the communication unit 33a in the server 33 can be connected to the above-described camera 100, a playback device (a large screen television (TV) 34a or a mobile phone 34b) owned or viewed by a grandmother, a grandfather, or the like through a network or the like. The server 33 can monitor whether or not the playback device is turned on and can be displayed via the communication network 32 and the communication unit 33a. It is also connected to an image storage server 35.

In the server 33, a user information unit 33e and a state determination unit 33f are provided, and user information, power supply and operation state determinations are recorded in association with each other. Further, an alternative database (DB) 33g connected to these parts is provided, and when the target device is powered off, it stores which device is to be replaced. If the other party is a very limited relative, data as shown in FIG. 3 may be recorded directly in the memory inside the camera 100. However, when a large number of viewers are assumed, it is difficult for the photographer to input viewing devices for all viewers. Therefore, it is better to provide a server for creating a database (DB) as shown in FIG. Good.

The server 33 has an appreciation content determination unit 33d, which appropriately monitors the content of the image that the user views (including resolution, file size, format, aspect ratio, etc.), and from this tendency, this alternative database (DB ) Create 33g content. Further, the diary / image recording unit 33b and the calendar unit 33i in the server 33 have a function for inputting and recording a schedule such as a diary, a blog article, an image, a calendar, and the like. It can also be read. Further, when an image cannot be transmitted to each device, the image may be temporarily stored in such a diary / image recording unit 33b.

Since it is configured as described above, when the camera 100 accesses the server 33, it is possible to determine a device that can be viewed by the user and to capture an image suitable for it. For example, in the case of a vertically long screen on the mobile phone 34b and a large-screen TV (TV) 34a having a wide screen, the method of determining the composition at the time of shooting also changes, so that shooting with a composition that matches the playback device is possible. In the example illustrated in FIG. 5, an example of a screen display that can record a high-definition (HD) moving image having an aspect ratio of 16: 9 is illustrated. By operating a switch for transmission setting (not shown) provided on the back of the camera 100, transmission setting can be performed, device information of the transmission partner is sent, and the screen size of the partner device is reflected, Information display as shown in FIG. 5 can be performed by a balloon.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the state of the transmission destination is determined before shooting, but in the second embodiment, the state of the transmission partner device is determined to prompt camera shooting. Since the configuration of the camera 100 and the server 33 in the second embodiment is the same as that of the first embodiment, detailed description thereof is omitted.

The operation in this embodiment will be described with reference to the flowchart shown in FIG. Steps S0 to S3 are the same as in the first embodiment. When the database reference in step S3 is completed, it is subsequently determined whether or not a device with high priority is on (S41). If the high-priority device has been turned on, it is next determined whether or not the priority has been changed (S44). If the priority is changed, a shooting instruction is given (S46). On the other hand, if the priority has been changed, the device information with the next highest priority is searched (S45), and the process proceeds to step S46, where an imaging instruction is given based on the searched device information.

In step S41, when the power of the high-priority device is off, the next-highest-priority device is searched (S42), and it is determined whether or not it is in another mode (S43). Other modes are the same as in step 9 (FIG. 4). If it is not the other mode, the process returns to step S41, and the above steps are repeated. If the other mode is selected in steps S10 and S43, the other mode is executed as in step S11.

If the result of determination in step S <b> 0 is shooting mode, step S <b> 21 and the subsequent steps are executed, but the processing here is the same as in the flowchart of FIG. 4 in the first embodiment, and detailed description thereof is omitted. .

As described above, in the flowchart shown in FIG. 6, the camera 100 constantly monitors whether the power of the destination device is turned on (S41 → 42, 43 → N). Is immediately ready to enjoy the image, the process proceeds from step S41 to step S46, and a shooting instruction, that is, information indicating which device is turned on is displayed to encourage shooting.

In addition, even if the priority of the mobile phone is initially high, the priority may change, such as the viewer's viewing environment changes and he / she wants to watch on a large screen television (TV) 34 from the middle (see FIG. 7). In this case, a priority switching signal may be received (S44 → 45) to prompt transmission to another device.

Next, a third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, transmission information is displayed when a captured image is transmitted while viewing a playback device. That is, in the third embodiment, transmission information indicating that image transmission has occurred is displayed at the corner of the large-screen television (TV) 34a (FIG. 8A), and the captured image is played back in earnest. Start (FIG. 8 (b) → (c)). In this case, for example, when the operation is performed by the remote controller 342 as shown in FIG.

The configuration of the third embodiment is the same as that of the first and second embodiments, but a screen division control unit 34a1 is provided inside the large screen television 34a as shown in FIG. The screen division control unit 34a1 can display two screens, and performs display control of the main screen 340 and the sub screen 341 (see FIG. 8).

Next, the operation of the large screen television (TV) 34a will be described with reference to the flowchart shown in FIG. First, it is determined whether an image is received directly from the camera 100 or via the server 33 (S101). If the result of determination is that no reception has been made, only the main screen 340 is displayed on the display screen of the large-screen television 34a. If it is received as a result of the determination in step S101, a reception display is performed (S102). As this reception display, as shown in FIG. 8A, the transmission source is displayed as text on the sub-screen 341. In addition to this, display may be appropriately performed such as displaying a symbol or the like.

Next, it is determined whether or not playback is OK (S103). Whether or not this reproduction is OK is performed by the remote controller 342 or the like. If playback OK is not performed, the process returns, but if playback OK is performed, the large-screen television (TV) 34a starts playback of an image captured by the camera 100. Subsequently, it is determined whether or not enlargement reproduction is performed (S105). Enlarged reproduction is also performed by the remote controller 342 or the like. As a result of the determination, when enlarged reproduction is performed, the captured image is enlarged and displayed on the main screen, while the television screen is reduced and displayed on the secondary screen 341 as shown in FIG.

If enlargement reproduction is not performed in step S105, it is determined whether or not reproduction is NG (S107). That is, when the photographed image is not reproduced as a viewer, the photographed image is transferred to the next candidate (S108). If the reproduction is to be continued, step S107 is skipped and the process returns.

In addition, when everyone is watching a large-screen TV (TV) 34a, there are cases where it is not desired to display a photographed image. Only when it may be displayed on the screen television 34a, image reproduction on the large screen television 34a may be permitted. In this case, the large screen television 34a may be operated instead of the mobile phone 34b. Such a system is possible by using the second embodiment (see FIG. 6).

In a playback device viewed by many people such as a large-screen TV, the viewer may be confused when the playback of a captured image suddenly starts. However, according to the third embodiment, the photographed image is displayed only when it is permitted after the photographed image is transmitted, so that the above-described problems can be prevented. Can do.

As described above, in each embodiment of the present invention, image transmission is performed when the transmission partner is in a state of viewing an image. Therefore, shooting suitable for the playback device is pursued while pursuing immediacy. It is possible to perform shooting with high satisfaction.

In the embodiment of the present invention, the display information of the camera 100 is displayed on the display panel 8 of shooting information for shooting corresponding to the playback device of the transmission destination, for example, switching between moving images and still images, and the image size. . For this reason, it is possible to perform shooting optimal for the playback apparatus of the transmission destination. Furthermore, in the embodiment of the present invention, when no playback device as the transmission destination is used (when the power is turned off and reception is impossible), the storage device other than the playback device such as the camera 100 or the server 33 is used. I remember it. For this reason, it becomes possible to transmit at a later date.

Furthermore, in the embodiment of the present invention, it is possible to set a plurality of playback devices as transmission destinations, and sequentially determine whether or not the other party is in use. If any playback device is available, it can be transmitted. Moreover, since it is made to perform in order from the reproduction | regeneration apparatus with a high priority in determination of whether it is a utilization state, possibility that it can transmit to the optimal reproduction | regeneration apparatus is high.

In each embodiment of the present invention, when the shooting mode is entered, it is not determined whether the viewer's playback device is in a usable state. However, when live view display is performed in step S21 or the like. Of course, the state of the viewer's playback device may be determined.

The camera in the present embodiment may be a compact camera or a single-lens reflex camera, or may be a camera built in a mobile phone or a PDA. The present invention can be applied to any imaging device that can transmit an image to a playback device.
