Next, the functional configuration of the electronic circuit of the digital camera 2 will be described with reference to FIG.
In the monitoring (through image display) state in the photographing mode which is the basic mode, the photographing optical axis of the lens optical system 22 constituting the photographing lens in which the focus position and the aperture position are moved by driving the motor (M) 21. A CCD 23, which is an image sensor disposed behind, is scan-driven by a timing generator (TG) 24 and a CCD driver 25, and outputs a photoelectric conversion output corresponding to a light image formed at fixed intervals for one screen.

  The photoelectric conversion output is appropriately gain-adjusted for each primary color component of RGB in the state of an analog value signal, then sampled and held by a sample hold circuit (S / H) 26, and digital data by an A / D converter 27 The color process circuit 28 performs color process processing including pixel interpolation processing and γ correction processing in the color process circuit 28 to generate a digital luminance signal Y and color difference signals Cb and Cr (YUV signals), and DMA (Direct Memory). Access) controller 29.

  The DMA controller 29 once uses the luminance signal Y and the color difference signals Cb and Cr output from the color process circuit 28 by using the composite synchronization signal, memory write enable signal, and clock signal from the color process circuit 28 once. And the DMA transfer to the DRAM 31 used as a buffer memory via the DRAM interface (I / F) 30.

  The control unit 32 includes a CPU, a non-volatile memory in which an operation program executed by the CPU is fixedly stored, a work memory, and the like. The control unit 32 controls the overall control operation of the digital camera 2. After completion of the DMA transfer of the color difference signal to the DRAM 31, the luminance and color difference signal (YUV signal) is read from the DRAM 31 via the DRAM interface 30 and written to the VRAM 34 via the display control unit 33.

  The display control unit 33 periodically reads the luminance and color difference signals from the VRAM 34, generates a video signal based on these data, and outputs the video signal to the display unit 35.

  The display unit 35 is composed of a color liquid crystal panel with a backlight, and is disposed on the back side of the digital camera 2 main body. The display unit 35 functions as a monitor display unit (electronic finder) in image shooting mode, and performs display control. By performing display based on the video signal from the unit 33, an image based on the image information taken in by the CCD 23, which is the image sensor at that time, is displayed in real time (through image display).

  In this way, when a through image that can be taken at that time is displayed in real time on the display unit 35, when a shutter key that constitutes a part of the key input unit 36 is operated at a timing at which still image shooting is desired, Generate a trigger signal.

  In response to the trigger signal, the control unit 32 cancels the DMA transfer of the luminance and color difference signals for one screen currently taken in from the CCD 23 to the DRAM 21, and again the aperture value and shutter speed according to appropriate exposure conditions. Then, the CCD 23 is driven to scan to obtain luminance and color difference signals for one screen and transfer them to the DRAM 31. Thereafter, this path is stopped and the state is changed to the storage and storage state.

  In this storage and storage state, the control unit 32 outputs the luminance and color difference signals for one frame written in the DRAM 31 through the DRAM interface 30 for each of Y, Cb, and Cr components of 8 pixels × 8 pixels horizontally. Are read in units called basic blocks of the data and written in a Joint Photographic Coding Experts Group (JPEG) circuit 37. The JPEG circuit 37 is an ADCT (Adaptive Discrete Cosine Transform), which is an entropy coding system. Data compression is performed by processing such as conversion.

  The obtained code data is read out from the JPEG circuit 37 as a data file of one image, and written into a memory card 38 provided as a storage medium of the digital camera 2.

  The memory card 38 includes a flash memory, which is a non-volatile memory, enclosed in a card-like casing and is detachably attached to the digital camera 2.

  Then, along with the compression processing of the luminance and color difference signals for one frame and the completion of writing all the compressed data to the memory card 38, the control unit 32 activates the path from the CCD 23 to the DRAM 31 again.

  The control unit 32 is connected to a key input unit 36, a strobe drive unit 39, a power supply control unit 40, and a USB interface (I / F) 41.

  The key input unit 36 is composed of the above-described shutter key and other keys, and signals accompanying these key operations are sent directly to the control unit 32.

  The strobe driving unit 39 charges a large-capacity strobe capacitor (not shown) during still image shooting, and then drives the strobe light emitting unit 43 to flash based on control from the control unit 32.

  The power supply control unit 40 is used to control the charging of a built-in rechargeable battery (not shown) such as a lithium ion battery, which serves as an operation power supply for the digital camera 2, and supply the generated power of the built-in rechargeable battery to the other circuits. The power line in the USB cable 12 is connected.

  The USB interface 41 performs communication control when image data and other data are transmitted / received to / from an external information device connected via the USB connector 42 disposed on the bottom surface of the digital camera 2, for example, the document table 1. Do.

  In addition, when the digital camera 2 is mounted on the document table 1 and used as a document camera, the USB interface 41 receives various control signals including switching between a static display and a through display under the control of the document table 1. The image data obtained by receiving and photographing based on the control is transmitted and output to the document stand 1 side.

  In addition to the normal shooting mode, a moving image can be shot by operating the operation mode key of the key input unit 36. At the time of shooting this moving image, after the shutter key 16 of the key input unit 36 is operated for the first time, the above-described storage of the still image data in the memory card 38 is executed continuously in time, and the shutter When the second operation of the key 16 is performed or a predetermined time limit, for example, 30 seconds elapses, a series of still image data stored in the memory card 38 is converted into a motion JPEG movie data file (AVI file). ) Set the memory again.

  In the playback mode, the control unit 32 selectively reads out the image data stored in the built-in memory 38, and the JPEG circuit 37 compresses the image data that has been compressed by a procedure completely opposite to the procedure of data compression in the shooting mode. The decompressed image data is held in the DRAM 31 via the DRAM interface 30, and then the content held in the DRAM 31 is stored in the VRAM 34 via the display control unit 33, and the display control unit 33 periodically receives the VRAM 34. The image data is read out to generate a video signal and output to the display unit 35.

  If the selected image data is not a still image but a moving image, playback of the individual still image data constituting the selected moving image data file is executed continuously in time, and all still images are When the reproduction of the image data is finished, only the still image data positioned at the head of the moving image data is reproduced and displayed until the next reproduction instruction is given.

Next, the operation of the above embodiment will be described.
In this embodiment, the automatic correction unit 11a in the control unit 11 on the document stand 1 side mainly performs recognition and setting based on the connection with the digital camera 2, and the user starts the digital camera. Suppose that it is performed sequentially while operating No. 2.

FIG. 8 is a diagram for explaining the processing contents that are executed mainly when the automatic correction unit 11a receives the connection detection signal from the USB interface 12 in a state where the digital camera 2 is mounted on the camera mounting unit 1d.
At the beginning of the operation, the document table ID information is read from the user setting data 14b of the storage unit 14 (step M01), and the document table ID information is read from the document table conversion data 14d of the height adjustment unit 15 (step M01). M02), the two document table ID information are compared to determine whether or not they match (step M03).

  Here, when it is determined that the two document table ID information matches, the user has set in advance, so the shooting distance information of the eyelid set in the user setting data 14b is read out and temporarily stored. 14a is temporarily held (step M04).

Next, the zoom field angle of the lens optical system 22 of the digital camera 2 connected to the camera mounting portion 1d is corrected as set (step M05).
FIG. 6 is a subroutine showing the detailed processing contents relating to the correction of the zoom angle of view. First, the zoom setting value information (A) and the shooting distance information (C) are read from the user setting data 14b (step S01).

Next, the shooting distance information (D) temporarily stored in the temporary storage unit 14a is read (step S02), and the corrected zoom information (E) is expressed by the following equation.
E = A * C / D (1)
(However, E: Zoom information after correction,
A: Zoom set value information,
C: Shooting distance information
D: Shooting distance information. )
(Step S03).

  Thereafter, the camera ID information is received from the connected digital camera 2 (step S04), and a plurality of camera conversion data 14c are searched based on the camera ID information (step S05), and whether there is matching data or not. Judgment is made (step S06).

  If it is determined that there is data corresponding to the camera conversion data 14c, then zoom MAX value information and zoom MIN value information are read from the corresponding camera conversion data 14c (step S07) and calculated in step S03. The zoom information E is compared with the zoom MAX value, and it is determined whether or not the zoom information E is equal to or greater than the zoom MAX value (step S08).

  If the zoom information E calculated in step S03 is greater than or equal to the zoom MAX value, the zoom information E is reset using the zoom MAX value (step S09).

  If the zoom information E is less than the zoom MAX value in step S08, the zoom information E calculated in step S03 is compared with the zoom MIN value, and whether or not the zoom information E is equal to or smaller than the zoom MIN value. Is determined (step S12).

  Here, when the zoom information E is larger than the zoom MIN value, it is determined that the correction of the zoom information E is not necessary, and the setting is not made to rewrite the contents, but it is determined that the zoom information E is equal to or smaller than the zoom MIN value. In this case, the zoom information E is reset using the zoom MIN value (step S13).

  In this way, after performing correction processing for rewriting the information zoom information E within the range indicated by the zoom MAX value information and the zoom MIN value as necessary, the zoom information E is output again from the temporary storage unit 14a and the zoom of the user setting data 14b. Re-set as set value information (step S10).

  In addition, the camera ID information received from the digital camera 2 in step S04 is updated and stored in the user setting data 14b (step S11), and the subroutine in FIG. 9 is terminated and the process returns to the main routine in FIG. To do.

  If there is no camera ID information received from the digital camera 2 in step S06, the digital camera 2 is mounted on the document table 1 and used as a document camera. After performing some error processing on the assumption that it cannot be performed (step S14), the subroutine of FIG. 9 is terminated.

  Further, in place of the error process in step S14, a new registration process for newly registering the digital camera 2 in the document table 1 including other information including the camera ID information of the digital camera 2 may be performed. .

  However, in the main routine of FIG. 8, after the zoom setting value information corrected in the subroutine of FIG. 9 is overwritten in the user setting data 14b (step M06), the zoom setting value information is transmitted to the digital camera 2. The zoom lens in the lens optical system 22 is moved by the motor 21 so that the zoom angle of view matches the set value (step M07).

  Thereafter, the contents read out in step S02 of FIG. 9 are newly set in the shooting distance information of the user setting data 14b (step M08), and the digital camera 2 is used as a document camera for use with the digital camera 2. Then, a process for updating the set value for macro shooting is executed (step M09).

  FIG. 10 is a subroutine showing the detailed processing contents related to the update of the macro shooting setting value. First, camera ID information is received from the digital camera 2 (step S31). Based on the camera ID information, a plurality of camera conversion data 14c are searched (step S32), and it is determined whether there is matching data (step S33).

  If it is determined that there is data corresponding to the camera conversion data 14c, then macro shooting presence / absence information is read from the corresponding camera conversion data 14c (step S34), and the digital camera 2 performs macro shooting from the read contents. It is determined whether or not the model is capable of performing (step S35).

  If it is determined that the model is capable of performing macro shooting, the macro shooting setting value of the user setting data 14b is read and output (step S36), and the subroutine of FIG. To return to the main routine of FIG.

  If it is determined in step S35 that the digital camera 2 is a model that cannot perform macro shooting, a process of outputting using the content that the macro shooting setting value is turned off is executed (step S37). This completes the subroutine of FIG. 10 and returns to the main routine of FIG.

  When there is no corresponding camera ID information received from the digital camera 2 in step S33, the digital camera 2 is mounted on the document table 1 and used as a document camera. After performing some error processing on the assumption that it cannot be performed (step S38), the subroutine of FIG. 10 is terminated.

  Further, in place of the error processing in step S38, new registration for newly registering the digital camera 2 in the document table 1 including other information such as camera ID information of the digital camera 2 and macro shooting setting value information is performed. Processing may be performed.

  However, in the main routine of FIG. 8, after the macro shooting setting value updated in the subroutine of FIG. 10 is written over the zoom setting value information in the user setting data 14b (step M10), the macro shooting setting value is set. Is also sent to the digital camera 2 to set the macro shooting on the digital camera 2 side, specifically, the motor 21 moves the focus lens in the lens optical system 22 to a predetermined macro shooting position (step M11). The processing by the automatic correction unit 11a in FIG.

  Thereafter, the document table 1 having the digital camera 2 mounted on the camera mounting portion 1d is caused to function as a document camera, and an image of a document document or the like placed on the document placement portion 1a is photographed and subjected to appropriate image processing. The image signal can be output to the projector device.

  As described above, when the digital camera 2 is mounted on the document table 1 and used as a document camera, the initial setting of the user necessary for the combination of the model of the document table 1 and the digital camera 2 is simplified, and immediately It is possible to shift to a shooting operation.

  In addition, in the above embodiment, the initial setting including the detection of the mounting of the digital camera 2 on the side of the document stand 1, which is one external device, and the subsequent model discrimination as seen from the digital camera 2 that performs shooting, etc. Since the processing is executed, so as to reduce the burden of control on the digital camera 2 side that performs general-purpose shooting, so that the document table 1 performs specialized initial settings including unique control as a document camera. In addition, finer settings can be made.

  Further, in the above embodiment, data of a plurality of models of digital cameras are stored on the side of the document stand 1 which is one external device connected to the digital camera 2 and the digital camera 2 is actually connected. In this case, it is assumed that a function for executing control such as initial setting is provided, but data storage for each external device, connection detection and initial setting control are all performed on the digital camera 2 side. It may be executed.

  FIG. 11 illustrates a first modification of the present embodiment that realizes such a function. This figure shows a circuit configuration of a digital camera 2 'in which a part of the circuit configuration of the digital camera 2 shown in FIG. 7 is changed. The parts not shown here have the same configuration as in FIG. Shall.

  That is, the control unit 32 ′ is provided with an automatic correction unit 32a equivalent to the automatic correction unit 11a of the control unit 11 of FIG. 3 and a storage unit 51 equivalent to the storage unit 14 of FIG.

  The storage unit 51 includes a temporary storage unit 51a, user setting data 51b, camera conversion data 51c, and document table conversion data 51d. The storage unit 51 includes a plurality of types of document prints on which the digital camera 2 'can be mounted. Consists of conversion data for the table.

  In this way, although the burden of the digital camera 2 for performing shooting is somewhat increased by providing the function of detecting and controlling the connection of the document stand 1 or the like, which is an external device, on the digital camera 2 'side, the digital camera 2 can centrally manage all the operation controls, so that it is possible to quickly shift to the photographing operation without taking time to transmit and receive control data to and from the document table 1 or the like.

  Further, various data relating to the document table 1 and the digital camera 2 are stored in an external storage medium, for example, a memory card, and the memory card is mounted on the document table 1, for example, not the document table 1 or the digital camera 2 By doing so, it may be possible to perform initial setting or the like by combination with the digital camera 2.

  FIG. 12 illustrates a second modification of the present embodiment that realizes such a function. This figure is a substitute for the circuit configuration of the document table 1 shown in FIG. 3, and the same reference numerals are used for the same parts and the description thereof is omitted.

  Thus, while the storage unit 14 ′ includes only the temporary storage unit 14 a, user setting data 61 a, camera conversion data 61 b, and document table conversion data 61 c are stored in the memory card 61 that is detachably mounted.

  Here, the camera conversion data 61b includes conversion data for a plurality of models of digital cameras that can be mounted on the document table. Similarly, the document table conversion data 61c also includes a plurality of models of document tables on which the digital camera can be mounted. Consists of conversion data.

  As described above, the removable memory card 61 stores the conversion data of both the digital camera and the document table as the weapon base, so that the memory card 61 itself can be easily rewritten by a personal computer or the like. Therefore, it is possible to easily cope with version upgrades for each model and increases in the models themselves, and the system expandability can be further improved.

  In the above embodiment, the case where the document table 1 and the digital camera 2 are combined and used as a document camera including the first and second modifications has been described. However, the present invention is not limited to this. Any system can be used as long as it has a system configuration in which the camera body and other external devices are connected and used.

  For example, it is not limited to either a digital camera using a solid-state image sensor such as a CCD or a silver salt camera using a silver salt film. Information such as the GN (guide number) of each external strobe and the presence / absence of zoom function of the illumination angle is stored in advance along with the corresponding strobe ID information on the camera body side, and when the external strobe is newly attached It is also possible to detect this and search for the corresponding information from the strobe ID information to control the light emission amount and zoom angle during strobe shooting.

  For example, when the strobe is composed of a combination of LEDs of a plurality of RGB colors, only the R (red) LED emits a little more light than the normal setting state, or only the B (blue) LED is emitted. The user can save settings such as strong flashing and so on for each flash unit in the camera, flash unit, or a separate storage medium. Once set, replace the flash unit. Even so, it is possible to quickly shift to appropriate shooting.

  Also, for example, it can be applied to an electric tripod that has an electric pan head, and the expansion and contraction of the leg portion can be electrically controlled. The leg length and the facing angle to the subject determined in advance by mounting the camera Etc. can be set.

  Furthermore, in the above-described embodiment, not only the setting is performed corresponding to one content stored in advance at the time of the initial setting, but also the setting operation while performing a flexible correction according to the user setting data or the like. Therefore, it is possible to construct a camera system that is more user-friendly by reflecting the user's intention of shooting at that time.

  In addition, since the conversion data stored in the storage unit can be appropriately rewritten, in this respect as well, the user's intention to shoot is similarly reflected, and a more convenient camera system is constructed. Can do.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention in the implementation stage. In addition, the functions executed in the above-described embodiments may be combined as appropriate as possible. The above-described embodiment includes various stages, and various inventions can be extracted by an appropriate combination according to a plurality of disclosed structural requirements.
