After performing gamma conversion and known image processing, A / D conversion is performed, and this is stored in the buffer memory 17. The buffer memory 17 is composed of two frame memories 17a and 17b. When one frame memory 17a is performing data compression processing or the like, the other frame memory 17b receives image data from the image processing unit 16. Can be written.

The data communication unit 13 includes a data compression unit 18,
It comprises an identification / instruction data generation unit 19 and a mobile phone unit 20. The data compression unit 18 uses the frame memory 17
One frame of digital image data is read from one of a and 17b, and the image data is compressed at a compression ratio of about 1/10 to 1/20 and the JPEG (Joint Photgraphic Experts Gro
up) Compress. The compressed image data is stored in the mobile phone unit 20.
Sent to Note that the data compression method is not limited to JPEG, and another well-known compression method may be used.

The identification / instruction data generation unit 19 generates identification number data (ID data) for identifying a camera user and print instruction data corresponding to various print commands input from the key input unit 21. These identification / instruction data are sent to the mobile phone unit 20. The print instruction data includes index print instruction data, single frame print instruction data, print size data, print number data, print reception instruction data, image data storage instruction data, image data medium recording instruction data, and in addition to these, Special print instruction data such as panorama print and trimming print can also be input. When these print instruction data are set in advance, they are stored in the memory and are output until the contents are changed thereafter. The print receipt instruction data indicates a desired print receipt time and a receipt method such as mailing, home delivery, or over-the-counter delivery.

The mobile phone unit 20 associates the compressed image data with the identification / instruction data, and transfers the data to the laboratory through the well-known mobile phone line 11, and the modem 24 and the mobile phone. And 25. Since the mobile phone 25 only transfers image data and identification / instruction data in the present embodiment, the call function is omitted. If there is a public telephone line or public telephone line available nearby, a connection terminal to a line port of a public telephone or the like is provided so that wired data transfer is possible. The data transfer is automatically performed after completion of each processing such as image pickup, image processing, image recording, data compression, etc., whereby the image data and the identification / instruction data are stored in the pre-registered print facility 11 of the laboratory store. Is transferred. In this way, when the image capturing is completed, this image data is transferred to the print facility 11 of the lab store together with the identification / instruction data, so that it does not matter what the storage capacity of the recording medium is, unlike a conventional camera. Unlimited shooting is possible even with frames. A frame identification number is attached to each image data in order to identify each frame. The frame identification number may be data obtained by photographing the date and time, instead of simply counting up the number of photographed frames.

Further, the data communication unit 13 has a browsing mode for browsing the image data transferred to the laboratory store. In this browsing mode, the camera 9 accesses the image storage file 31 of the lab store, and the index image or single frame image of each frame taken so far is taken into the camera 9 side, and this is read by the electronic viewfinder or display of the camera 9. Further, it is selectively displayed on a display separate from the camera.

A printing facility 10 for printing on the basis of the transferred image data is installed in the lab store.
The printing facility 10 includes a data receiving unit 30, an image storage file 31, a digital printer 32, a bill issuing printer 33, and a system controller 34.

The data receiving unit 30 is a modem 35 connected to a telephone line, and a data converting unit 3 for decoding the data from the modem 35 into image data and identification / instruction data.
6 is comprised. The image data and the identification / instruction data from the data conversion unit 36 are stored in the image storage file 31 by the system controller 34 using the identification data as search data.

Based on the print instruction data, the system controller 34 controls the digital printer 32 to create the hardware copy 45, as shown in FIG. First, the print reception desired time is read out of the print instruction data, and the image data is read out and digitally printed from the data when the print reception desired time is imminent. At that time, the one-frame print instruction data, the index print instruction data, the print size data, and the number-of-prints data of the print instruction data are read, and each printing is performed according to these instruction contents. In addition, the back side printing machine 42 can identify the identification number and the bar code of the identification number by the hard copy 4.

In 3, the customer name is specified from the identification number, and the contents of the invoice such as the customer name, the delivery date and time, the delivery place, and the amount of money are printed. Since the identification number and its bar code are also recorded on the invoice, the completed hard copy 45 can be grouped for each identification number by automatically reading them, and the hard copy 45 and the invoice can be automatically collated. Has been 1
They are put together and packed in bags. The hardware copy 45 packed in a bag is sent by mail based on the print receipt instruction data.
Delivery methods such as home delivery and over-the-counter delivery are specified and sorted. Then, these are mailed, delivered to the home, or delivered over the counter according to each sort.

Further, the system controller 34 reads the image data storage instruction data out of the print instruction data, and if the image data storage instruction data is instructed, the image data is not erased for a predetermined period of time without being erased. Save it. As a result, the image can be viewed and downloaded from the camera 9 or through personal computer communication. In the case of the print instruction data only and there is no instruction to save the image data, the corresponding image data in the image storage file 31 is deleted at the stage when the printing and the print verification are completed. Further, in the case of the image data in which the image data medium recording instruction data is recorded, after the image data is written in the large capacity storage medium such as MO, CD-ROM, MD, the corresponding image data in the image storage file is erased. To do.

As shown in FIG. 2, the digital printer 32
Is provided with a printing exposure unit 40 of a scanning exposure system using laser light. The print exposure unit 40 prints and exposes each frame by scanning the printing beam in the width direction of the color paper 41 in synchronization with the feeding of the color paper (silver salt color photosensitive material) 41. Further, in the case of an index image, a large number of images are reduced and printed in a normal one frame size.

On the back surface of the color paper 41, an identification number and its bar code are printed by the back printing machine 42 at positions corresponding to the print target frames. The identification number and the bar code are used for matching the hard copy with the bill. The printing exposure unit 40 may use a surface exposure method or a line exposure method using another CRT, a liquid crystal display panel or the like, in addition to the scanning exposure method using laser light. Also, after printing, a cut mark is recorded in the margin of each frame by a marker 43 such as a puncher. The color paper 41 which has been printed and exposed is developed by a paper processor 44, as is well known, and cut off for each frame based on a cut mark to form a hard copy 45.

Although the above embodiment uses the photographic print type digital printer 32, a heat development transfer type color printer, a color ink jet printer, a color thermal printer or a color laser printer may be used.

In the above embodiment, the image data is digitally printed, but in addition to this, character data and document data input by a word processor or the like are sent to a laboratory store by personal computer communication or the like, and the image data sent earlier is transmitted. These characters and document data may be image-synthesized and printed. Also, instead of synthesizing images of characters and document data,
Using the back printing machine 42 as shown in FIG.
You may print on the back surface of No. 5.

Further, high resolution image data may be obtained by using a pixel shifting method. For example, the image area sensor of the image pickup unit is moved by a piezoelectric element or the like on the image formation screen in a range narrower than one pixel interval to sequentially pick up images, and image data having a resolution higher than the number of pixels of the image area sensor is artificially obtained. obtain. In this case, the data representing the pixel shift position (x, y coordinates) and the corresponding image data are transferred to the laboratory store. Then, instead of encoding the image data alone, the inter-image difference data is encoded by utilizing the fact that the correlation between the sequentially-shifted pixel-shifted images is high (since the same scene is captured). By using the method of encoding the inter-image difference data in this way, the amount of stored and transferred data can be reduced. At a laboratory store, high-resolution image data is created and printed by pixel complementation processing using pixel-shifted position data and corresponding image data. At this time, image processing such as smoothing and enhancement may be added as necessary.

Further, the present invention may be applied to a video camera for taking a moving image. Almost the same scene appears before and after the frame image at a certain time. When the screen is completely stationary, the noise generated between the imaging input system and the recording system can be effectively removed by taking the average value of a plurality of frame images during the stationary time. Further, when the screen is moving (when the screen is moved within a predetermined allowable range), the moving image has the effect of the pixel shift. Therefore, by using the image data of the frames before and after the print target frame for the pixel complementing process, pseudo high resolution image data is obtained. In this case,
Although it is necessary to find the direction and the moving distance on the pixel, the direction and the moving distance can be found by performing local matching between frames. For example, when an image n frames after the image at a certain time has moved by (dx, dy) pixels on the pixels of the image area sensor, the pixels are shifted by (dx / n, dy / n) per frame. Can be regarded as a thing. Note that dx represents the amount of movement in the x-axis direction, and dy represents the amount of movement in the y-axis direction. Then, the frame image at the timing when the pixel shift amount (dx / n, dy / n) takes a value that is not an integer is used as the pixel complementing data.

In the above embodiment, the data communication unit 13 is provided integrally with the digital still camera 9, but these may be separable. Further, a call function may be added to the data communication unit 13 so that the camera and the mobile phone can be used in common. Further, in the above embodiment, the camera 9 and the printing facility 10 are connected by the mobile phone line 11, but in addition to this, they may be directly connected by radio.

In the above-described embodiment, the print instruction data is input on the camera side and transferred together with the image data. However, the print instruction data is registered in advance in the laboratory and only when there is a change, this May be contacted later by telephone or the like. Further, the shooting condition data may be transferred together with the image data. The photographing condition data includes photographing date / time, photographing lens focal length, subject distance, subject irradiation light source type, weather, temperature, etc. By using these at the time of printing, print quality can be improved. Further, when instructing additional printing, since the image data has already been transferred, the identification data and the number of prints are printed by the camera 9 using the printing equipment 1.
It is sufficient to transfer the data to 0, so that additional printing can be easily performed.

Although the above embodiment is a print system between an individual user and a laboratory store, it may be applied to a print system between a photographer at a newspaper company or a television station and the head office. In this case, an image with immediacy can be easily obtained.

In the above embodiment, the digital still camera 9 is composed of the still camera body 12 and the data communication section 13, but in addition to this, an IC card can be mounted,
Image data may be stored in this. In this case, the printing service may be provided by submitting the IC card to a lab store, if necessary. Further, it is possible to pass only the image data from a camera or an IC card to a lab store near the place where the user is out and receive or deliver a print from the lab store near his / her home. In this case, the IC card stores the customer identification number and, if necessary, data such as address and name.

In the above-described embodiment, the identification data and the instruction data are transferred together with the image data for each photographing, but in addition to this, as shown in FIGS. 3 and 4, the data is compressed by the digital still camera 49. It is also possible to provide a data memory 22 for storing a plurality of frames of image data, and transfer the data after photographing a plurality of frames. In this case, the data memory 22 is provided between the data compression unit 18 and the mobile phone unit 20. Then, the image data and the print instruction data are stored in the data memory 22 in association with each other. In FIG. 3, the same components as those in FIG. 1 are designated by the same reference numerals. This still camera body 5
Reference numeral 0 includes an image display circuit 51 and a liquid crystal display panel 52, and the captured image can be confirmed on the liquid crystal display panel 52.

In addition to the image data and the print instruction data, the data memory 22 also stores unique data such as identification number data for identifying the camera user and destination telephone number data. Note that these unique data may be registered in the destination memory of the mobile phone unit 20 instead of being stored in the data memory 22, and may also be stored in the internal memory of the system controller 14.

In the case of collectively transmitting the data of a plurality of photographed frames, the user identification number data is also transferred in addition to the image data, the frame identification data, and the print designation data of the series of frames. The transfer of this user identification number is
As in the above embodiment, identification data for each frame,
In addition to sending the image data and the print instruction data, each image data and these print instruction data may be collectively transferred by using the identification data as a footer. It is convenient to transfer each data for each shooting frame because it is not necessary to transfer the transferred shooting frames again when the communication line is cut off due to a radio wave interference during the transfer. In this case, when each frame is normally received, the printing equipment transmits a normal reception signal after the reception of each frame is completed.
As a result, if the line is disconnected during communication, it is sufficient to retransmit from the interrupted frame, and communication costs can be reduced. In FIG. 4, when data is not normally received, data is transferred until it is normally received.
A limit may be set on the number of times this data is retransmitted. In this case, an alarm is generated when the number of times exceeds a certain number. Further, the user identification number data and the frame number identification data may be used in combination, and in this case, the user and the shooting frame can be identified by one identification number.

The image data of a plurality of frames recorded in the data memory 22 is transferred after a certain number of frames are photographed as shown in FIG. 4, or when a certain amount of data is accumulated in the data memory 22. Alternatively, the data may be transferred. Also,
The accumulated image data, identification data, and print designation data may be transferred after a lapse of a certain time after the photographing is completed. Further, the manual transfer mode may be set and manual data transfer may be performed appropriately. In addition, when transferring the data, if the camera 9 is in an incommunicable area such as a building or an underground mall, the data transfer standby mode is automatically set. In this data transfer standby mode,
Data transfer is performed when the camera 9 enters the communicable area.

When the image data transmission is completed and a normal reception signal is received from the receiving side, the transmission record is recorded in the data memory 2.
After being stored in the predetermined area 2, the transmitted image data and its print instruction data are automatically deleted from the data memory 22. The transmission record data includes transmission date / time data, transmission frame identification number data, print reception designation data, and the like. In addition to automatic deletion, these data may be deleted manually. Also,
Instead of sending a normal reception signal from the reception source, when the reception is normal, the reception shop may issue a reception ID number and the reception source may transmit the reception ID number. In this case, the camera side stores the received reception ID number in the data memory 22.

The transfer destination of the image data is not only transferred to the one registered in the camera in advance, but also the image data transfer destination list is stored in the data memory 22 of the camera, and the data is selected from these to select the data. You may transfer. In this case,
A reception facility 60 as shown in FIG. 5 is provided for each area.
The reception facility 60 is generally installed in a lab store, but it may be installed independently.

The reception facility 60 comprises a data receiving section 61, a temporary storage file 62, a recipient data decoding section 63, a retransmitted data generating section 64, a retransmitted file creating section 65, a data transmitting section 66, and a system controller 67. ing. The data receiving unit 61 and the data transmitting unit 66 are composed of modems 70 and 71 and data converting units 72 and 73. The transmission data from the digital still camera 49 received by the data receiving unit 61 is stored in the temporary storage file 62 and is also sent to the recipient data decoding unit 63.
The receiver data decoding unit 63 decodes the receiver from the transmission data and sends the receiver data and the identification data to the retransmission data generator 64. The retransmitted data generating unit 64 creates retransmitted data with the recipient as the destination, based on the recipient data, and sends this and the identification data to the retransmitted file creating unit 65. Based on the identification data, the retransmitted file creating unit 65 reads the image data of the corresponding identification data and the print instruction data from the temporary storage file 62, and creates a retransmitted file with the print recipient as the destination. The retransmitted file created is the data transmission unit 6
6 is sent to the print facility 10 of the intended print recipient via the dedicated line 75. Therefore, since the printing is performed at the print receiver, the user can receive the print in the shortest delivery time. The transmission of the retransmitted file may be performed by using the private line 75 or by using a network such as the Internet using a general public line.

The transfer destination of the image data may be automatically selected based on the current position information of the camera. Entering the current position information of the camera is easy, the photographer himself
It is performed by keying in a place name or the like with the key input unit 21. In this case, the place name and the image data transfer destination are associated with each other and stored in the memory of the camera, and the image data transfer destination is specified from the place name. In the case of a camera equipped with a global positioning system (GPS), the current position is specified based on this GPS signal, and the transfer destination is specified based on this. In addition to this, in the case of the mobile phone unit 20 for which the receiving base station information can be obtained, the location of the receiving base station may be an approximate current location. In this way, by selecting the data transfer destination closest to the current position of the camera, the communication cost when using the mobile phone line can be minimized. Further, by inputting the current position information, a list of a plurality of image data transfer destinations close to the current position may be displayed on the liquid crystal display panel 52, and a desired data transfer destination may be selected from these. .

The print recipient information of the print instruction information is set at a predetermined place, for example, at home or the nearest DP.
In addition to the reception shop, the camera may change the print recipient each time. In this case, the place name and the print receiving destination data may be stored in the camera in advance in association with each other and automatically selected based on the current position information of the camera. Similar to the transfer destination of the image data, the print receiving destination may also specify the nearest receiving place or the like based on the place name data, the GPS signal, and the receiving base station information. In this case, by inputting the desired print receipt time as the print receipt instruction data, it becomes possible to receive the print at the designated place at the designated time when traveling or the like. Further, by inputting the current position information, a list of a plurality of print receivers close to the current position may be displayed on the liquid crystal display panel 52, and a desired receiver may be selected from these.

In the above embodiment, the photographed image data is compressed and transferred. However, in addition to this,
Although the transfer efficiency is reduced, the image data may be transferred as it is without being compressed. Further, the captured image data may be transferred after being confirmed on the display of the camera.

[0039]

According to the present invention, since image data is transferred,
It is possible to suppress an increase in the storage capacity of image data in the camera. Moreover, since it is only necessary to store at least one screen of image data, the number of image data for one screen can be increased accordingly, and high resolution image data can be obtained. Further, since the photographer is not restricted by the memory capacity, he / she can perform high-quality image pickup many times without limitation.

Further, since the image data is transferred and stored in a large-scale storage file at the transfer destination, it is possible to save the trouble of bringing a negative film or a recording medium to a DP reception shop or the like in order to obtain a print. You can In addition, at DP reception shops and lab stores, without manual reception processing,
Reception processing, sorting, billing processing, etc. can be performed automatically.

Further, since the photographing condition data is transferred together with the image data, the print quality can be improved by printing using the photographing condition data. Further, by providing the camera with the storage unit for storing the captured frame and the recording unit for the transfer image data, it is possible to take a new image even during the transfer image processing. In addition, high-resolution image data can be obtained and the amount of stored and transferred data can be reduced by performing image pickup by the pixel shift method and encoding difference data between sequentially photographed pixel shift images.

Since the camera is equipped with the data communication unit for transferring the image data of the subject, the identification data corresponding to the image data, and the print instruction data, it is not necessary to visit a DP reception shop or the like to easily order prints. it can. Moreover, since the data is transferred after the photographing is completed, a quick print process can be performed. Further, since the identification data is composed of the user identification data and the shooting frame identification data, the transferred image data can be surely identified.

The data communication unit is provided with storage means for storing image data for a plurality of frames, and the data communication unit automatically transfers the image data for a plurality of frames stored in the storage means after photographing a fixed number of frames or a fixed amount of data. Therefore, the storage means is not filled with image data. Besides, photo film and I
It is not necessary to prepare a recording medium such as a C card each time, and printing can be easily performed.

When the normal reception signal from the receiving side is received after the data transfer, the image data having the data transferred stored in the storage means is deleted, so that the image data can be transferred successfully due to communication failure or the like. The image data will not be deleted when there is not.

When a plurality of data transfer destinations are stored and the data communication unit selects a data transfer destination close to the current position of the camera based on the current position data of the camera, the data communication unit can be used when a mobile phone line or the like is used. Communication costs can be reduced. Similarly, a plurality of print recipients are stored, and the data communication unit selects a print recipient near the current position of the camera based on the current position data of the camera, and uses this print recipient data as print instruction data. By including and transferring the data, it is possible to specify a recipient in the vicinity, and it is possible to obtain a print photograph more quickly. Further, the current position information of the camera can be automatically and easily input by inputting the receiving base station information or the GPS signal. The camera configuration can be simplified by manually inputting the current position information.
