ADVANTAGE OF THE INVENTION According to this invention, when imaging | photography of broadcast images , such as a television , fails, the camera and image transmission system convenient for imaging | photography can be provided again .

Hereinafter, a preferred embodiment will be described using a camera to which the present invention is applied and an image transmission system according to the drawings. In this embodiment, when a TV image being received by one-segment broadcasting or the like is shot, the server searches for a high-quality image based on the shooting timing (date and time information) and its composition, and the searched high-quality image is a camera. So that the camera can record high-quality images. In addition, using data communication such as one-segment broadcasting, billing is made for broadcast data including re-broadcast time information, and a warning is issued when re-broadcasting in the received broadcast data.

  FIG. 1 is a block diagram of a digital camera and its surroundings according to an 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 an operation, 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. For cameras that allow the user to switch the shutter speed and control the exposure appropriately by controlling the aperture and sensitivity, if the shutter speed is generally slowed down, for example, when shooting a river flow, the water flow stretches like a thread. Can be described. If the shutter speed is increased, even if the same river flow is photographed, that moment can be captured, and the moment when the splashes rise and the state of ripples can be reproduced in detail. Even in sports photography, if the shutter speed is increased, the movement of the subject can be stopped and the facial expression can be clearly captured.

  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 5b 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. For example, a shape determination unit 5a that detects the shape of what is being imaged from the contour information obtained by processing the image information, and a face detection unit 5d that checks the characteristics of the image and detects the position of the main subject. Included in this system. This is for optimizing the shooting control by determining what kind of photo the user is going to take at the time of shooting.

  The image processing unit 5 has a function of determining the contrast of the image described above, and controls autofocus in conjunction with the focusing unit of the photographic lens. The distance of the subject, the distance of the background, and the like can be determined based on information on the lens position when the photographing lens 2 is focused. Furthermore, the image processing unit 5 is connected to a broadcast receiving unit 5c that receives a TV broadcast. The broadcast receiving unit 5c can reproduce the received image and display it on the display panel 8. The user can switch the broadcast display mode by operating switches (1a to 1c) described later. As a result, in addition to the images acquired by the photographing lens 2 and the image sensor 3, this broadcast image can be photographed while being monitored.

  However, since the image taken at this time is a signal sent for moving image viewing, the image quality is not sufficient for viewing as a still image. Therefore, as will be described later, a higher-definition image is acquired again via the data transmission / reception unit 9c based on the image obtained at this time. At this time, the broadcast accompanying data included in the obtained broadcast signal may be simultaneously acquired and recorded.

  The camera 100 also includes a compression unit 6, a recording unit 9a, a recording medium 9, a data transmission / reception unit 9c, a rebroadcast timing transmission request unit 9d, a display panel 8, a display control unit 8a, and a multi-image processing unit 8b. Yes. 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 the image signal, in addition to the broadcast-accompanying data, time information at the time of taking a picture may be recorded together. The photographing time information is measured by a clock unit 1t in the MPU 1 described later, and the MPU 1 associates with the image.

  The photographed image data recorded on the media 9 or the recording unit 9a is transferred to another device such as a server 34 for managing images via the communication line 32 such as the Internet or a mobile phone by the data transmission / reception unit 9c, or a television set. An image can be transmitted to the server 34 of the broadcast station 33 that performed the broadcast. The image transmitted to the server 34 can be immediately shown to the third party 31, and communication can be promoted while viewing the image.

  Of course, the transmission operation to the server 34 may include a transmission setting means for designating the transmission destination, but the broadcast reception unit 5c transmits the data to the access destination based on the data broadcast obtained when the television broadcast is received. Also good. Further, the data to be transmitted at this time may be not only an image but also a data transmission requesting to send information at the time of rebroadcast when there is an image missed by the user. For this reason, a rebroadcast timing transmission requesting unit 9d that generates data for requesting transmission of rebroadcast timing information is arranged between the data transmitting / receiving unit 9c and MPU1.

  The display panel 8 is composed of, for example, a liquid crystal or an organic EL, and displays a subject image for observation at the time of photographing, and displays an expanded recorded image at the time of reproduction. The display panel 8 displays television broadcast images received via the broadcast receiver 5c and the data transmitter / receiver 9c.

  The display control unit 8a 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. By this multi-image processing unit 8b, it is possible to display characters of a destination address and various warnings on the captured image and the captured image. The re-broadcast timing information and the like are also displayed by the multi-image processing unit 8b. The display panel 8 displays a list of images that have been taken and transmitted, and from there, an image to be uploaded to a blog service or the like operated by the server 34, or a layout for uploading and displaying the image on a blog can be selected. You may do it.

  The camera 100 is provided with an auxiliary light emitting unit 11, 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 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.

  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. Further, whether or not to display a code indicating the address of the site server 51 on the display panel 8 is performed by detecting changes in these switches. Further, the MPU 1 functions as a shooting control unit that controls the AF control unit 2a, the aperture control unit 2c, and the like during shooting.

  Next, with reference to FIG. 2, an explanation will be given focusing on the exchange of images and information among the camera 100 with a television (TV) reception function, the broadcasting station 33 and the server 34. FIG. 2 is a diagram illustrating a system for acquiring a high-quality still image including the camera 100, the broadcasting station 33, and the server 34.

  In the broadcasting station 33, there are a detailed image A41, a detailed image B42, and the like as high-quality still images corresponding to moving images to be broadcast in programs and commercials, and these images are stored in the storage unit. The broadcast database 43 stores data such as the broadcast date and time of these programs and commercials. In addition, a one-seg unit 44 is provided for transmitting programs and commercials as one-seg broadcasting.

 In addition, the server 34 operated by the broadcasting station 33 or operated by the one that cooperates with the broadcasting station 33 receives a high-quality image transmission request, a re-broadcast timing transmission request, and the like from the camera 100. On the other hand, a transmission / reception unit 45 for transmitting images and information such as high-definition images and rebroadcast timings is provided. The transmission / reception unit 45 can communicate with the camera 100 via a communication line such as the Internet or a cellular phone network.

  In addition, a reception determination unit 46 and an image determination unit 47 are provided in the server 34. The reception determination unit 46 is a determination unit that receives a signal such as a transmission request from the camera 100 and determines the content thereof. Further, when receiving a high-quality image transmission request from the camera 100, the image determination unit 47 searches and determines the corresponding high-quality image from the detailed image A41, the detailed image B42, and the like.

The operation of the system according to this embodiment will be described with reference to FIG.
First, the broadcasting station 33 performs one-segment broadcasting of programs and commercials from the one-segment section 44. The one-segment method is not sufficient for viewing still images in terms of image quality, but when this one-segment broadcast is received by the one transmitting / receiving unit 5c of the camera 100 ("a" in FIG. 2), it is reproduced and displayed on the display panel 8. .

  When the photographer displays a favorite image in the one-segment broadcast image displayed on the display panel 8, for example, when an idol in the broadcast image has a favorite expression, the release is performed in the same manner as a normal camera. Press the switch and perform shooting operations. At this time, a signal indicating the push-in timing and a captured low-quality broadcast acquisition image 48 are transmitted to the broadcast station 33 via the data transmission / reception unit 9c ("A" in FIG. 2). This transmission timing is performed when the camera 100 enters a hot spot and wireless transmission becomes possible, or when the camera 100 is connected to the Internet via a PC. Further, if transmission is possible between the camera 100 and the mobile phone, transmission may be performed at the time of shooting using a mobile phone communication network.

  The broadcast station 33, in advance, provides a high-definition image (may be a high-definition image) that can withstand still image viewing corresponding to each frame of the moving image, in addition to the image for broadcasting the moving image in the one-segment unit 44, the detailed image A41, the details Prepared as image B42 and the like. In addition, when a high-definition image is broadcast with the image quality for one-segment broadcasting being dropped, a still image may be generated from the original image.

  When the timing information transmitted from the camera 100 via the route “a” in FIG. 2 and the low-quality image are received by the transmission / reception unit 45, a high-quality still image of the frame broadcast at that timing is searched and searched. The high-quality still image is transmitted to the camera 100 (“c” in FIG. 2). Here, the signal from the camera 100 is determined by the reception determination unit 46, and the image determination unit 47 performs an image search based on the determination result. The retrieved high-quality still image 49 is sent to the user of the camera 100 via the transmission / reception unit 45 and the communication line 32 such as the Internet.

  The reception determination unit 46 determines whether the user is requesting rebroadcast information. As a result of the determination, if the rebroadcast information is requested, the contents of the broadcast database (DB) 43 are searched, and information such as the rebroadcast date and time is transmitted from the transmission / reception unit 45 to the camera 100.

  By adopting such a configuration, a high-quality still image 49 corresponding to this image is retrieved from the broadcast acquisition image 48 that is not so high in definition, and transmitted to the camera 100 via the communication line 32. An image with better image quality can be acquired while taking a TV image.

  Further, when the shooting is missed, the camera 100 can acquire the timing of the rebroadcast by making use of the characteristics of the broadcast that can repeatedly receive the content. That is, it is possible to request the data of the next broadcast time information, and it is possible to try shooting at a better timing, or another image (detail image A41 or detail image B42) in which the same idol appears. It is possible to enjoy the shooting of different facial expressions and poses.

  In the description of the present embodiment, a diagram is shown in which the functions are distributed to the broadcasting station 33 and one server 34 in order to avoid a burden on only the broadcasting station 33. It may be possible to obtain only the broadcast DB from the broadcast station by having separate contents. For example, the CM of company X may be managed by server X, and the CM of company Y may be managed by server Y. In this case, using a data communication function in one-segment broadcasting or the like, information on services performed there may be transmitted for each server, and the desired service may be received by accessing the server. Of course, the functions of the server 34 may be concentrated on the broadcasting station 33.

  Note that the image data of the broadcast acquired image 48 is used in order to prevent another image from being sent due to an error in the broadcast timing. This is because there is a possibility that the timing at which the broadcast station 33 transmits the moving image and the timing at which the camera 100 acquires the moving image may not match, so that the high-quality still image is searched using the image data as well. I have to. However, if there is no error in the broadcast timing and reception timing, this system can be established with only timing information. With such a service, there is an advantage that an improvement in shooting opportunities with a camera improves shooting skills, and broadcast stations and CM creators can repeatedly view the content.

  Next, the operation of the camera 100 will be described using the flowchart shown in FIG. First, when the camera control flow starts, it is determined whether or not a broadcast is received (S1). This is a determination as to whether or not the photographer has operated the operation switches 1b and 1c of the camera 100 to switch to the one-segment broadcasting reception mode. As a result of the determination, if the broadcast is not received, the process proceeds to step S2 and subsequent steps in order to perform normal camera control.

  Step S2 and subsequent steps are normal photographing operations, and photographing and recording with the original camera are performed using the photographing lens 2 and the image sensor 3 of the camera. First, it is determined whether or not shooting is performed, that is, whether or not the release button is pressed and the release switch 1a is turned on (S3). If the result of the determination is that the image is taken, the image of the subject imaged on the image sensor 3 is photoelectrically converted to obtain image data (S3). Subsequently, the acquired image data is recorded in the recording unit 9a or the medium 9 (S4), and the process returns when the recording is completed.

  In step SS2, if it is not shooting, it is next determined whether or not to reproduce (S11). If the result of determination is playback, the image data recorded on the recording unit 9a or the medium 9 is displayed on the display panel 8 (S12). The image reproduced here is an image photographed through the photographing lens 2 or an image transmitted and acquired from the broadcasting station 33 or the like as described with reference to FIG. In addition, you may comprise so that image transmission can be performed from the data transmission / reception part 9c by setting transmission to the image reproduced | regenerated here. Each of the above steps is a generally performed shooting and transmission flow.

  In the present embodiment, a person appearing on a television broadcast screen can be displayed on the display panel 8 and can be photographed as if in front of the eyes, as in normal photographing with a camera. When such a broadcast reception mode is set, as a result of the determination in step S1, it is determined that the broadcast reception mode is set, and the process proceeds to a television shooting flow in step S21 and subsequent steps.

In the television shooting flow, first, a television station is selected, and the broadcast receiving unit 5c reproduces a television signal from the broadcast wave and displays a television image on the display panel 8 (S21). Next, it is determined whether or not shooting is performed, that is, whether or not the release button is fully pressed (S22). As a result of the determination, when a shooting operation is performed, a part of the broadcast moving image is temporarily recorded at the timing when the release button is operated based on the moving image received by the broadcast receiving unit 5c (S24).
Since the image recorded here is based on a moving image, the image quality is poor. For this reason, temporary recording is performed in this step.

  Next, the shooting timing is recorded together with the shooting (S25). The photographing timing is performed based on the output of the clock unit 1t in the MPU1. As described above, the shooting timing is recorded and transmitted to the server 34 later, and is used when selecting an image desired by the user when acquiring a higher quality image than the broadcast image. At the same time, an access destination signal of the server 34 or the like when requesting an image may be acquired.

  Subsequently, it is determined whether or not the setting of the broadcast reception mode has been canceled (S26). If the broadcast reception mode has not been canceled, the process returns to step S21 to repeat the above steps. In order to obtain a high-quality image corresponding to the image obtained in the above-described television shooting flow, it is only necessary to connect to the network and execute step S31 and the subsequent steps. Details will be described later.

  In step S26, if the result of determination is that the broadcast reception mode has been cancelled, it is determined whether or not data reception has been performed (S35). This is because a high-quality still image or rebroadcast information is transmitted from the server 34 when an image request is made in step S32 described later. In step S35, it is determined whether or not these data are received, and if received, the received data is recorded (S36). In step S35, if no data is received for a predetermined time, the process returns.

  If the result of determination is that it is not playback mode, it is next determined whether or not the date and time of rebroadcast has come (S15). In step S34, a request for rebroadcast timing transmission regarding the rebroadcast date and time is requested to the server 34. When information regarding the rebroadcast date and time is acquired in step S36, whether or not this rebroadcast date and time is determined. Judgment is performed.

  If the result of determination in step S15 is not the date and time of rebroadcast, the process proceeds to step S31 and subsequent steps, and a high-quality image corresponding to the image obtained in the television shooting flow is obtained. First, it is determined whether to connect to the network and perform an image request operation (S31). This is performed by detecting whether the broadcast image recorded in steps S22 to S25 does not request a high-quality image from the server 34 and the camera 100 is in an environment where the server 34 can be accessed. .

  If an image request is made as a result of the determination in step S31, communication based on the access destination information described above is performed, and the temporarily recorded broadcast image and shooting timing are transmitted (S32). As a result, the server 34 connected to the network searches for a still image that the photographer wants to photograph and transmits the image data and the like. When the camera 100 receives image data or the like, step S35 described above is branched to Y, and the received image data or the like is recorded in step S36.

  Next, it is determined whether a rebroadcast request is to be made (S33). In this step, when it is desired to take a picture again by re-broadcasting due to a shooting mistake or missed shooting, the setting is performed by the operation switches 1b and 1c. Determine whether or not. As a result of the determination, if a request has been made, the rebroadcast timing transmission request unit 9d transmits the request to the server 34 (S34). At this time, the same person appears, but if there is another version of the commercial, that version may be selected. Such information is acquired and displayed at the time of data reception in step S35 described above. If this request is made during access to the server 34, the server 34 sends the rebroadcast date / time data, so that it is recorded in the aforementioned step 36.

  If it is determined in step S15 whether or not it is a rebroadcast date and time, it is a rebroadcast date and time. (S16). This is because if the broadcast image is suddenly reproduced during the original photographing as a camera, the original photographing as a camera is hindered. Therefore, if the result of determination is that shooting is in progress, a warning is displayed (S17), and reproduction of this broadcast image is prohibited. On the other hand, if the image is not being photographed, the process proceeds to step S21, where the above-described steps are executed to reproduce the rebroadcast image and photograph.

  Thus, according to the camera of the present embodiment, both real shooting and virtual shooting using broadcast images can be enjoyed. Even when virtual shooting has failed, it is possible to enjoy another shooting opportunity based on the next chance information or another version broadcast information. In addition, according to the present embodiment, even if the broadcast image is simply passively watched, if a good scene is found, it can be taken immediately, and even if it does not work, the next chance is enjoyed. It is possible, and there is no need to go out to find a shooting scene somewhere.

  Next, the operations in the broadcasting station 33 and the image management server 34, that is, the control of the image transmission destination server 34 to which the camera 100 transmits images will be mainly described with reference to the flowchart shown in FIG.

  FIG. 4A shows the flow of the broadcasting station 33. When the broadcasting station 33 reaches a predetermined time (S101), it broadcasts a predetermined program or CM (S102). The server 34 obtains a database 43 of programs to be broadcast at this predetermined timing, sends a high-definition image suitable for a still image from the data and shooting information transmitted from the camera 100, and also announces a rebroadcast. Send data.

  The operation of the server 34 is shown in FIG. As described above, in step S <b> 32 (FIG. 3), the camera 100 accesses the net and transmits shooting information including a temporarily recorded image and shooting timing to the server 34. Therefore, first, it is determined whether or not this shooting information has been operated (S111). As a result of the determination, if shooting information has been received, the timing information can be used to determine which program and commercial the user wanted to shoot and whether re-broadcasting was desired. Therefore, first, an image search is performed from candidate images (detailed images) based on the shooting timing and the temporarily recorded image, and the corresponding detail image is transmitted to the camera 100 via the network (S112).

  Further, it is determined whether or not the camera 100 has requested re-broadcast date / time information (S113). As a result of the determination, if requested, information on the date and time when the program or commercial is broadcast next time is transmitted from the broadcast database 43 of the broadcast station 33 via the network. Based on this information, the camera 100 receives, reproduces, or issues a warning during the next broadcast, and allows the user to recognize that the rebroadcast shooting timing has come.

  As described above, in the present embodiment, in cooperation with the service of the broadcast station 33 and the server 34, it is possible to capture not only actual shooting but also a virtual image, and a camera that doubles enjoyment can be provided.

  That is, in this embodiment, the broadcast receiving unit 5c that receives the first image (broadcast image 48) broadcast from the broadcast station 33, the display panel 8 that reproduces and displays the first image, and the display panel 8 The release switch 1a for instructing to take an image displayed as a still image, and a second image (detailed image A41, details) prepared by the broadcasting station 33 based on information according to the operation timing of the release switch 1a. A data transmitting / receiving unit 9c for acquiring the image B42) is provided.
