Abstract
A photographic apparatus is described which outputs a photographed image immediately to paper by a simple operation. The photographic apparatus includes an electronic camera for electronically acquiring an image, a connection base for removably connecting the electronic camera thereto, the connection base having a function of reading out image data from the electronic camera while the camera is connected thereto, and a printing section for acquiring the image data from the connection base and outputting an image based on the image data to paper.
Description
- 1. Field of the Invention
- This invention relates to a photographic apparatus for outputting an image photographed using an electronic camera such as a digital camera to paper.
- 2. Related Prior Art
- In recent years, a solid state imaging apparatus which makes use of a CCD unit has exhibited remarkable increase in resolution and storage capacity, and efforts are directed to development of an electronic apparatus for electronically fetching an image such as an electronic still camera or a digital video recorder.
- In such a situation as described above, the electronic still camera exhibits such improvement that it is as good as that using silver salt film, and the electronic still camera is utilized not only for general use but also for professional use thanks to a data holding property and facility in after-processing in addition to the improved definition.
- However, when an image is electronically fetched using such an electronic camera as described above, in order to output the image to paper, it is necessary to start up a computer to which a printer is connected and transfer the image data to the printer through the computer.
- Thus, the electronic camera has a problem in that, in order to output image data to paper, a computer must be started up in this manner, and the image data cannot be outputted immediately.
- Further, in order to allow image data to be outputted directly to paper without intervention of a computer, it has been proposed to provide an electronic camera with a printer controlling function or to provide a printer with a function of fetching image data from an electronic camera.
- However, provision of an electronic camera with a function of controlling a printer not only disturbs miniaturization or ease of use of an electronic camera but also invites an increase in cost. On the other hand, if a printer is provided with a function of fetching image data from an electronic camera, then an increase in cost of the printer itself is invited.
- Further, since an electronic camera and a printer are connected to each other by a cable, each time it is intended to perform outputting to paper, connection and disconnection of the cable must be performed. Thus, cumbersome operation is required.
- It is an object of the present invention to provide a photographic apparatus which can output a photographed image immediately to paper by a simple operation.
- In order to attain the object described above, according to the present invention, there is provided a photographic apparatus, including an electronic camera for electronically acquiring an image, a connection base for removably connecting the electronic camera thereto, the connection base having a function of reading out image data from the electronic camera while the camera is connected thereto, and printing means for acquiring the image data from the connection base and outputting an image based on the image data to paper.
- In the photographic apparatus, the electronic camera is removably connected to the connection base, and image data read out from the electronic camera is acquired by the printing means through the connection base and outputted to paper by the printing means. Consequently, when photographing is to be performed, the electronic camera can be removed from the connection base to acquire an image, but when the acquired image is to be outputted to paper, the electronic camera can be connected to the connection base to establish electric connection between the electronic camera and the printing means to allow the printing means to perform such outputting of the image data to paper.
- Consequently, the photographic apparatus is advantageous in that an image photographed by the electronic camera can be outputted to paper without using a computer and can be outputted immediately after it is photographed. The photographic apparatus is advantageous also in that, since transfer or image processing of image data acquired by the connection base is performed, there is no necessity to provide such functions to the electronic camera or the printing means, and consequently, simplification and reduction in cost of the electronic camera and the printing means can be achieved.
- The above and other objects, features and advantages of the present invention will become apparent from the following description and the appended claims, taken in conjunction with the accompanying drawings in which like parts or elements denoted by like reference symbols.

Further, aflash shoe 52 is provided on theadapter 5 so that a flash apparatus (not shown) as a separate member may be attached to theadapter 5. A female thread (not shown) for mounting a tripod on theadapter 5 is formed in a lower wall of theadapter 5. - A battery for the
electronic camera 2 is accommodated, for example, in the grip G of theadapter 5 so that, when theadapter 5 is mounted on theconnection base 3, the battery is charged automatically from theconnection base 3. - The
electronic camera 2 and theadapter 5 are secured to each other, for example, by means of screws, and theshutter button 51 and theflash shoe 52 of theadapter 5 and theelectronic camera 2 are synchronized with each other over a cable C2. - The
electronic camera 2 and theconnection base 3 can be connected to each other by the cable C3 so that, for example, when theadapter 5 is attached to a tripod and photographing is performed with the position of theelectronic camera 2 fixed, image data can be transferred from theelectronic camera 2 at the position to theconnection base 3 over the cable C3. - It is to be noted that, even if the
electronic camera 2 and theconnection base 3 are not connected to each other by the cable C3, if theelectronic camera 2 is mounted onto theconnection base 3 together with theadapter 5 after photographing is completed, then electric connection is still established so that image data stored in theelectronic camera 2 can be transferred in response to an instruction from theconnection base 3. - Referring now to FIGS. 3A and 3B, the
electronic camera 2 is shown in perspective views as viewed from the front side and the rear side, respectively. Theelectronic camera 2 uses a CCD unit (not shown) to fetch image data of an imaging object and stores the image data into an internal memory. In particular, theelectronic camera 2 can fetch an image through a lens L.

adapter 5 is fitted into therecess 31 of theconnection base 3 as shown in FIG. 6B, thencontacts 5 a of theadapter 5 and the other ends of the contact pins 3 b are brought into contact with each other. Consequently, image data acquired by the electronic camera 2 (refer to FIG. 1) can be sent from thecontacts 5 a of theadapter 5 to theboard 3 a of theconnection base 3 through the contact pins 3 b. - FIG. 7 shows an internal construction of the
connection base 3. Referring to FIG. 7, theconnection base 3 includes an interface driver 301 (for example, RS-232C) with theelectronic camera 2, another interface driver 302 (for example, IEEE 1284) with theprinting section 4, a button-LED section 303 including inputting buttons and indicating LEDs, anLCD module 304, aDRAM 305, aflash ROM 306, and aCPU 307. TheCPU 307 and the other components are connected to each other over a data bus and an address bus. - In the
connection base 3 having such a construction as described above, an image data transferring instruction is provided to theelectronic camera 2 through theinterface driver 301 which matches with, for example, the RS-232C. Meanwhile, image data transferred from theelectronic camera 2 is acquired through theinterface driver 301 and cumulatively stored once into theDRAM 305. - The image data stored in the
DRAM 305 is read out in response to a request from the printing section and transferred to the printing section over theinterface driver 302 which matches, for example, theIEEE 1284. - FIG. 8 shows an internal construction of the
printing section 4. In particular, theprinting section 4 includes, as principal components thereof, aninterface driver 401, aninterface controller 402, amemory controller 403, aDRAM 404, acolor pallet 405, amasking ROM 406, aprogram ROM 407, anEEPROM 408, and asystem CPU 409. - Image data outputted from the

DRAM 404 under the control of thememory controller 403 is converted into data for printing (for example, C, M, Y data) through thecolor pallet 405 and is outputted to a print board (PRT BOARD) through themasking ROM 406. - Subsequently, a photographing procedure using the photographing apparatus of the present embodiment is described. First, the user removes the
adapter 5 and theelectronic camera 2 from theconnection base 3 shown in FIG. 1. Such removal can be preformed by a single operation of depressing thebutton 32 shown in FIG. 4. - Then, the user will grasp the grip G of the
adapter 5 and perform photographing of an image object using theelectronic camera 2. FIG. 9 schematically illustrates a manner in which a photograph for certificate is taken. In this instance, theelectronic camera 2 is located at a position spaced by a distance d (for example, approximately 1.5 m) from a person acting as an image object. In this instance, a tripod may be attached to theadapter 5 to fix the position of theelectronic camera 2. - Here, where the
electronic camera 2 is of the manual focus and manual diaphragm type, in photographing in a flashlight emitting mode, first the diaphragm is kept open so that focusing may be performed readily, and then, after focusing is completed, the diaphragm is adjusted manually in accordance with a required flashlight amount immediately prior to release of the shutter. - Since the
display unit 21 is provided on the rear wall of theelectronic camera 2, an image of the imaging object displayed on thedisplay unit 21 can be visually observed by the user, and the focusing described above is performed by the user referring to the displayed image. Further, an automatic exposure adjustment mechanism (AE) operates till an instant at which the shutter is released, and consequently, the display on thedisplay unit 21 does not become dark upon focusing. - It is to be noted that, where the
electronic camera 2 is of the type wherein the diaphragm operates in association with the shutter, no manual diaphragm operation is required. - After such adjustment as described above is performed, the user will depress the
shutter button 51 provided on the grip G of theadapter 5. Alternatively, a shutter operation may be performed using an infrared remote controller or a timer may be used to perform a shutter operation after lapse of a predetermined time. - In response to the depression of the
shutter button 51, an image of the imaging object is fetched into theelectronic camera 2 and stored into the internal memory of theelectronic camera 2. - The image stored in the memory can be displayed on the display unit21 (refer to FIG. 3) in response to a key operation of the
electronic camera 2 and consequently can be confirmed by the user. It is to be noted that this operation may be performed alternatively by an operation of a button of theconnection base 3 side with theelectronic camera 2 mounted on theconnection base 3. - Then, printing of the photographed image is performed. In order to perform such printing, one of the images cumulatively stored in the memory which is to be printed is selected. This selection may be performed by an operation of a key of the
electronic camera 2 or by an operation of a button on theconnection base 3 side after theelectronic camera 2 is mounted onto theconnection base 3. It is to be noted that mounting of theelectronic camera 2 onto theconnection base 3 can be preformed by a single operation of placing and pushing the electronic camera 2 (with theadapter 5 attached thereto) into the recess 31 (refer to FIG. 4) of theconnection base 3. - After an image to be printed is selected, selection of a mode in which printing is to be performed (a divisional number, a color or white/black) and setting of a color tone, a sharpness degree and so forth) is performed by operations of the buttons of the
connection base 3, and then the printing button B6 (refer to FIG. 5) is depressed. - When the printing button B6 (refer to FIG. 5) is depressed, a command is sent from the
connection base 3 to theelectronic camera 2, and image data to be printed is read out from the memory of theelectronic camera 2. - Image data stored in the memory of the
electronic camera 2 is compressed data (for example, JPEG compression). Thus, the image data read out is decompressed by theconnection base 3 and stored into the built-in DRAM 305 (refer to FIG. 7). - Thereafter, the
connection base 3 performs image processing in accordance with the contents of adjustment set in advance (a color tone, a sharpness degree and so forth), a divisional number, and selection of a color mode or a white/black mode, and transfers image data obtained by the processing to the printing section 4 (refer to FIG. 1). It is to be noted that part of such image processing may be performed by theprinting section 4 side by providing such instruction from theconnection base 3 to theprinting section 4. - After the image data is transferred to the
connection base 3, theelectronic camera 2 can be removed from theconnection base 3 to perform some other photographing even before the printing is completed. The timing at which theelectronic camera 2 can be removed can be conveyed to the user by a display of the indicator I (refer to FIG. 5) provided on theconnection base 3. - The printing section4 (refer to FIG. 1) to which the image data has been transferred can perform printing processing to paper based on the image data.
- Here, a printing operation of the
printing section 4 is described with reference to cross sectional views of FIGS. 10 to 13. Theprinting section 4 may be a thermal sublimation type printer and includes, as principal components thereof, apaper tray 411, aplaten 412, aribbon cartridge 413, ahead 414 and ahead motor 414 a as shown in FIG. 10. In the stage of preparation for printing, thehead 414 stands by at a position spaced from aribbon 413 a of theribbon cartridge 413. - If a printing instruction is sent from the connection base3 (refer to FIG. 1) and image data is transferred to the
printing section 4, then apaper sheet 411 a is supplied from thepaper tray 411 and fed to theplaten 412 under the guidance of various rollers and apaper guide 415 as seen in FIG. 11. Thereupon, a leading end of thepaper sheet 411 a is brought into abutment with and held by achuck 412 a of theplaten 412. As a result, when theplaten 412 rotates, thepaper sheet 411 a is wrapped at an accurate position around theplaten 412 without being displaced. - Then, the
head 414 is driven by thehead motor 414 a so that it is brought into a contacting condition with theribbon 413 a as shown in FIG. 12. Then, after thepaper sheet 411 a wrapped around and fed by theplaten 412 comes to the position of thehead 414, thehead 414 is driven based on the image data so that ink of theribbon 413 a is successively transferred to thepaper sheet 411 a. - After the
platen 412 is rotated until an image based on the image data is formed fully on thepaper sheet 411 a, thehead 414 is brought out of contact with theribbon 413 a and theplaten 412 is rotated in the opposite direction as seen in FIG. 13 to its original position. - Then, the
paper sheet 411 a on which the image is formed is fed along adischarge paper guide 416 while it is pressed down by ahold roller 412 b until it is sent into adischarge paper tray 417. The printing of the image onto the paper is completed by such a sequence of operations as described above. - As described above, after an image is acquired by the
electronic camera 2, printing of the image onto paper can be performed simply by operation of theconnection base 3. - It is to be noted that, while, in the embodiment described above, the
electronic camera 2 which principally is in the form of a digital still camera is used, the present invention is not limited to this and can be applied to an electronic camera which alternatively is in the form of a digital video recorder. In this instance, recorded images are reproduced by operation of theconnection base 3, and the reproduction is stopped temporarily at an image to be printed. Then, the image data at which the reproduction is stopped is transferred to theprinting section 4. - Further, while, in the embodiment described above, electric connection between the
electronic camera 2 and theconnection base 3 is established by contact between the contact pins 3 b (refer to FIG. 6) and thecontacts 5 a (refer to FIG. 6) or by means of wiring lines of the cable C3 (refer to FIG. 2), data may alternatively be transmitted in a wireless fashion using infrared rays or the like. - While a preferred embodiment of the present invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
