Description

Combination apparatus for photograping image and method

The present invention relates to a composite photographing apparatus and method, and more particularly, to a composite photographing apparatus for storing images captured by a first and a second imaging unit driven independently of each other on a selected one of the first and second recording media; It is about a method.

In general, a digital still camera (DSC) converts an image incident through a lens into a digital signal and stores it in a recording medium such as a hard disk or a memory card. That is, the photographed image may be stored in the recording medium without recording the film or the like, and the digital image may be directly input to the computer without using a scanner. Such digital still cameras are highly compatible with personal computers, making it easy to edit and modify them, and transfer images taken by connecting to an external computer. In addition, since the digital still camera has the same structure as a general camera, it is easy to carry. That is, the digital still camera includes a lens device, a memory device, a signal modulator, a display device, and the like. However, such a digital still camera is mainly used for capturing still images for reasons such as the capacity of a recording medium for recording an image. That is, although it has a function to shoot some video, it is practically impossible to shoot for a long time. In particular, since there is no device for recording and playing sound together during video recording and playback, it is practically unsuitable for recording and storing and playing video. In order to satisfy this point, recording / reproducing apparatuses, such as camcorders, which record and reproduce images and sounds of a subject photographed on a recording medium such as a tape, are widely used.

The camcorder includes a lens device, a signal conversion device, a deck device for recording / reproducing photographed images, a display device, and the like. Such a camcorder mainly uses a cassette tape as a recording medium, and mounts the cassette tape on a deck device to record a moving picture. In addition, the camcorder is equipped with a microphone device and a speaker device, and can be recorded for more than 1 hour on the cassette tape. Such a camcorder also has a function of capturing still images, but is inferior to the image quality of the digital still camera described above, and thus is mainly used for capturing moving images. In addition, since a camcorder has more functions and a complicated configuration than a digital still camera, it is common that the volume is relatively large and expensive.

By the way, as described above, in order to utilize the functions of the digital still camera and the camcorder, it was necessary to purchase both products. Therefore, the economic burden on the consumer was much. In addition, since there is a distinctive function of each after the purchase, there is a troublesome problem to carry both products.

In order to solve this problem, a digital camera integrated camcorder in which a digital camera and a digital camcorder are integrated into one case has been developed, which is referred to as a digital camera / camcorder or duocam for short.

The duocam needs at least one recording medium for storing the captured image. The recording medium that may be provided in the duocam may be classified into an internal recording medium and a removable recording medium. The built-in recording medium is provided inside the duo cam, so the user does not need to prepare and mount the recording medium separately. However, due to the limitation of the storage capacity, no further recording is possible when the storage space of the recording medium is used up. Therefore, there is a disadvantage in that data already stored is deleted, and the removable recording medium has the advantages and disadvantages of the built-in recording medium. Therefore, it is preferable that the duo cam includes both a built-in recording medium and a removable recording medium. In the case where a plurality of recording media is provided in one photographing apparatus, it is necessary for the user to select a recording medium in which the captured image is stored. Will be generated.

In addition, there may be various types of removable recording media used in the Duocam. The recording media have different image quality and different price when the recorded image is reproduced. There is a need to select a recording medium to be stored. If a plurality of recording media are installed in the duocam, there is no device or system for storing the captured image on the recording media desired by the user, so the duocam arbitrarily stores the image data on any one of the plurality of recording media. If you store the problem, the valuable data recorded by the user may be deleted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to store images captured by the first and second imaging units each independently driven on any one of the first and second recording media. To provide a composite photographing apparatus and method.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a perspective view of a composite photographing apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram of a composite photographing apparatus according to an embodiment of the present invention. 1 and 2, the composite photographing apparatus (duo cam) includes a main body 100, a composite photographing unit 200 connected to the main body 100, and a mode selection switch unit 300.

Referring to FIG. 2, the composite imaging unit 200 may include a digital still camera (DSC) lens unit 211, a DSC imaging unit 221, a DSC lens driving unit 231, and a digital video camcoder (DVC). Video camcorder) lens unit 212, DVC imaging unit 222, and DVC lens driving unit 232. The DSC lens unit 211, the DSC imaging unit 221, the DVC lens unit 212, and the DVC imaging unit 222 may be driven independently because the types of images to be captured may be different. Meanwhile, referring to FIG. 1, the composite imaging unit 200 is provided with a battery mounting unit 22 in which the battery 60 is detachably mounted.

Referring to FIG. 2, the DSC lens driver 231 drives the DSC lens unit 211 under the control of the DSC controller 142. The optical image formed through the DSC lens unit 211 is photoelectrically converted into an electrical signal by the DSC imaging unit 221, and the converted signal is transmitted to the DSC signal processing block 111. The DSC imaging unit 221 reads out data in a progressive (sequential) method, because the progressive method is a method suitable for processing still image data. The progressive method captures still images by capturing one frame at a time instead of dividing the frame into fields, resulting in a very fine picture.

The DVC lens driver 232 drives the DVC lens unit 212 under the control of the main controller 141. The optical image formed through the DVC lens unit 212 is photoelectrically converted into an electrical signal by the DVC imager 222, and the converted signal is transmitted to the DVC signal processing block 112.

The interlaced scheme alternately reads image information of one frame in odd / even fields in 1/60 second increments. Mainly used for shooting. On the other hand, if you capture a fast moving object, you can see that the moving object appears in a horizontal line in the image. This is the difference in phase caused by the movement of the object for 1/60 second. In this case, it is possible to use a filter to eliminate the horizontal lines.

3A to 3E are diagrams provided for explanation of the composite image pickup unit. The composite image pickup unit 200 is rotatably installed at least 180 degrees about the Z axis from the side of the main body 100 by a user's manipulation. According to the rotation angle of the composite image pickup unit 200 with respect to the main body 100, one of the DSC image pickup unit 221 and the DVC image pickup unit 222 provided in the composite image pickup unit 200 performs imaging. The imaging unit positioned in the range R of the upper and lower 45 degrees with respect to the left side of the X axis is to perform imaging.

Although the DSC lens unit 211 and the DSC imaging unit 221 are located within a range of 45 degrees up and down relative to the left side of the X axis, the DSC imaging unit 221 enters the DSC operation mode in which imaging is performed. It works. Referring to FIG. 3C, the DSC lens unit 211 and the DSC imaging unit 221 are located within a range of 45 degrees left and right with respect to the upper side of the Y axis. In this case, the DSC lens unit in the composite imaging unit 200 is included. The DVC lens unit 212 and the DVC image pickup unit 222 symmetrically positioned opposite to the 211 and the DSC image pickup unit 221 are positioned within a range of 45 degrees left and right with respect to the lower side of the Y axis. Therefore, the lens unit and the image capturing unit located within the range R of 45 degrees up and down relative to the left side of the X axis do not exist, and in this case, no image capturing unit performs imaging.

3D and 3E, the DSC lens unit 211 and the DSC imaging unit 221 are positioned within a range of 45 degrees up and down with respect to the right side of the X axis. In this case, the DVC lens unit 212 and the DVC The imaging unit 222 is positioned within a range R of 45 degrees up and down with respect to the left side of the X axis. Therefore, the DVC imaging unit 222 positioned in the upper and lower 45 degrees of the angle (R) with respect to the left side of the X axis performs imaging.

The DVC signal processing block 112 processes image data received from the DVC imaging unit 222 on a field-by-field basis. You can change it. The video / audio signal processing block 182 compresses the digital image data received from the DVC signal processing block 112 into data in the DV format, because the DV format is a method suitable for compressing video data.

JPEG and DV format signals are stored in the memory 121 or in the magnetic tape 122 through the VCR deck 124. The storage path in which signals of JPEG and DV formats are stored in one of the memory 121 and the magnetic tape 122 may be set or reset by a user by a recording medium setting unit (not shown).

The memory 121 may be a built-in memory installed inside the main body 100 or may be a removable IC memory card. An IC memory card is a type of recording medium shaped like a card. The IC memory card stores one or more semiconductor memories in a case and has an interface connector at its end, and is used to expand the storage capacity. IC memory cards used in composite image pickup apparatuses can be classified according to the type of memory stored therein, such as RAM cards and flash memory cards. 4 shows a case where a removable IC memory card is installed.

The display character generator 173 receives a control signal from the main controller 141 and generates a specific character at a specific position of the display 150. In addition, since the captured image is transmitted to the display unit 150 in combination with the character generated by the display character generator 173, the user can check the captured image.

The 1394 interface unit 191 is used to exchange data with other external devices, and is mainly used to interface with a PC. That is, the photographed digital image data may be sent to the PC through the 1394 interface unit 191, and conversely, the digital image data may be received from the PC and recorded on the magnetic tape 122.

Referring to FIG. 1, the display unit 150 includes a viewfinder 151 that displays an image photographed on the main body 100 and an LCD panel 152 provided on the main body 100. Referring to FIG. 2, the display unit 150 receives and displays information on a selected operation mode and a recording mode from a display character generator 173 operating under the control of the main controller 141, and displays a video signal processing block. 181 and an image received from the video / audio signal processing block 182 are displayed.

The recording medium setting unit (not shown) outputs a recording mode signal to the main controller 141 so that the JPEG and DV format signals are stored in the recording medium selected by the user among the memory 121 and the magnetic tape 122. The recording medium setting unit may include a key input unit 130, a display character generator 173, and a display unit 150. The key input unit 130 displays a menu for inputting a command for displaying a menu screen on a display unit, a direction key for moving the cursor with respect to items arranged so as to be selectable on the menu screen, and selecting an item where the cursor is located. A selection key is provided. The key input unit 130 transmits a menu display signal when the user presses a menu display, a cursor movement signal when the direction key is pressed, and an item selection signal when the selection key is pressed, to the main controller 141. The main controller 141 controls the display character generator 173 to display the menu screen on the display unit 150 when receiving the menu display signal, and displays the character generator 173 when the cursor movement signal is received. Control to display the cursor moved to the position at 150. On the other hand, when the main controller 141 receives the item selection signal, the display character generator 173 controls the display unit 150 to display the subordinate menu of the item, and if the subordinate menu does not exist, the menu item. The operation corresponding to the above is executed.

5A through 5B are diagrams for explaining a process of setting a recording medium using a menu screen. As shown in FIG. 5A, when the user presses a menu mark, a menu screen is displayed on the display unit, and the cursor moves to '1. Record media 'and press SELECT. '(1) memory' and '(2) magnetic tape', which are subordinate menus of the recording medium ', are displayed. As shown in FIG. 5B, when the user later moves the cursor to the magnetic tape using the direction key and presses a selection key, the controller sets the storage path so that the video signal formatted on the magnetic tape is stored. do.

The key input unit 131 is provided with a photographing switch unit (not shown). The photographing switch unit outputs a photographing execution signal for capturing any one of a still image and a moving image to the main controller 141. The photographing switch unit sends a still image photographing execution command signal for photographing a still image to the main controller 141. And a moving image shooting switch for outputting a still image shooting switch to be output and a moving image shooting execution command signal for shooting a moving image to the main controller 141. That is, when the user presses the still image shooting switch, the still image shooting execution command signal is output, and when the video shooting switch is pressed, the moving image shooting execution command signal is output to the main controller 141.

The controller 140 is composed of a main controller 141 and a DSC controller 142. The main controller 141 determines whether the current operation mode is the DSC operation mode or the DVC operation mode based on the operation mode signal received from the mode selection switch unit 300. If it is determined that the DSC operation mode, the main controller 141 controls the DSC controller 142 so that the DSC controller 142 controls the DSC lens driver 231 and the DSC signal processing block 111. Therefore, the optical image formed through the DSC lens unit 211 is photoelectrically converted into an electrical signal by the DSC imaging unit 221, and the converted signal is subjected to a signal processing step in the DSC signal processing block 111 to perform a video signal processing block. In 181, the data is compressed into JPEG format data. On the other hand, if it is determined that the DVC operation mode, the main controller 141 controls the DVC lens driver 232, the DVC signal processing block 112, the video / audio signal processing block 182, and the VCR deck driver 123, The optical image formed through the DVC lens unit 212 is photoelectrically converted into an electrical signal by the DVC imaging unit 222, and the converted signal is subjected to a signal processing step by the DSC signal processing block 112 to perform a video signal processing block ( In 182, the data is compressed into DV format data.

The main controller 141 receives the recording mode signal from the recording medium setting unit, determines the recording medium corresponding thereto, and designates a storage path. When the main control unit 141 receives the still image shooting execution command signal from the shooting switch unit, the main controller 141 receives the recorded still image signal. When the compressed JPEG format signal is received and the moving picture photographing command signal is received, the DV format signal obtained by compressing the captured moving picture signal is stored in one of the memory 121 and the magnetic tape 122, respectively.

Referring to FIG. 1, one end of the main body 100, that is, a rear end of the main body 100 exposed in the photographing direction X, includes a speaker 13 for outputting a reproduced sound and an external sound. Microphones 132 are provided respectively.

The mode selection switch unit 300 is installed to operate in conjunction with the composite image pickup unit 200 and outputs a corresponding operation mode signal to the main controller 141 according to the position change of the composite image pickup unit 200. In the present embodiment, since the composite image pickup unit 200 is rotatably installed with respect to the main body 100, the mode selection switch unit 300 outputs an operation mode signal corresponding to the rotation angle of the composite image pickup unit 200. The main controller 141 receives the operation mode signal to determine the current operation mode.

As shown in Fig. 3A, when the DSC lens unit 211 and the DSC image pickup unit 221 are located within a range of 45 degrees up and down relative to the left side of X, the mode selection switch unit 300 is in the DSC operation mode. The signal is output to the main controller 141, the controller 140 operates the DSC imager 221, and the DVC imager 222 is turned off. Meanwhile, as shown in FIG. 3E, when the DVC lens unit 212 and the DVC imager 222 are positioned within an angle of 45 degrees up and down relative to the left side of X, the mode selection switch unit 300 is DVC. The operation mode signal is output to the main controller 141, the controller 140 operates the DVC imager 222, and the DSC imager 221 is turned off.

6 to 9 are diagrams provided for explanation of the mode selection switch unit. FIG. 6 is a perspective view provided to explain a switching switch which is an example of the mode selection switch unit 300 of FIG. 2. Referring to FIG. 6, the changeover switch may include a first terminal and a second connection pattern 161 and 162 provided in the main body 100, and a connection terminal provided in the composite imaging unit 200 to be connected to any one of the connection patterns 161 and 162. 230). In the above configuration, each of the main body 100 and the composite image pickup unit 200 are relatively rotatably coupled to face the holes h1 and h2. Therefore, the connection terminal 230 is in contact with the first connection pattern 161 or the second connection pattern 162 according to the rotation angle of the composite image pickup unit 200 with respect to the main body 100. Here, the first connection pattern 161 is connected to the first port of the main control unit 141, the second connection pattern 162 is connected to the second port of the main control unit 141.

FIG. 7 is a diagram illustrating a state where the DSC image pickup unit 221 is selected by the changeover switch shown in FIG. 6. In this case, as shown in FIG. 7, when the connection terminal 230 contacts the first connection pattern 161, that is, the rotation angle of the composite image pickup unit 200 is in the first range (the connection terminal 230 is X). In the range of 90 degrees up and down relative to the left side of the axis, the binary signal '1', which is a DSC operation mode signal for operating the DSC imaging unit 221, is output to the first port of the main control unit 141, The binary signal '0' is output to the second port of the main controller 141. Accordingly, the DSC operation mode in which imaging is performed by the DSC imaging unit 221 is selected, the control unit 140 operates the DSC imaging unit 221, and turns off the DVC imaging unit 222.

In addition, when the connection terminal 230 is in contact with the second connection pattern 162, that is, the rotation angle of the composite image pickup unit 200 is in the second range (the range where the connection terminal 230 is 90 degrees up and down relative to the right side of the A axis). In the case of 2), the binary signal '1', which is a DVC operation mode signal for operating the DVC imaging unit 222, is outputted to the second port of the main controller 141, and the first of the main controller 141. The binary signal '0' is output to the port.

The first and second connection patterns 161 and 162 may be in contact with the connection terminal 230 at an angle of about 180 degrees. Therefore, any one of the DSC and the DVC imaging units 221 and 222 can be operated at all rotation angles with respect to the main body 100 of the composite imaging unit 200. Preferably, the imaging unit located on the left side of the Y axis in FIG. 6 is driven, and all of them can be driven at the rotation angle included in the position. Accordingly, the DSC and DVC imaging units 221 and 222 are switched on and off by a switching switch based on the Y axis.

FIG. 8 is a perspective view provided as an example of a switching switch as an example of the mode sensing unit 300 of FIG. 2. In addition to the first and second connection patterns 161 and 162 provided on the main body 100, the changeover switch illustrated in FIG. 8 further includes third and fourth connection patterns 163 and 164, and among the connection patterns 161 to 164. It may be configured to include a connection terminal 230 provided in the composite image pickup unit 200 to be connected to any one. Accordingly, the connection terminal 230 is in contact with any one of the first to fourth connection patterns 161 to 164 according to the rotation angle of the composite image pickup unit 200 with respect to the main body 100. Here, the first connection pattern 161 is connected to the first port of the main control unit 141, the second connection pattern 162 is connected to the second port of the main control unit 141, the third and fourth connections The patterns 163 and 164 are not connected to the ports of the main controller 141.

FIG. 9 is a diagram illustrating a state in which no imaging unit is selected by the changeover switch shown in FIG. 8. In this case, as shown in FIG. 9, when the connection terminal 230 is in contact with the third connection pattern 163, that is, the rotation angle of the composite image pickup unit 200 is in the third range (the connection terminal 230 is Y). In the range of 45 degrees left and right with respect to the upper side of the axis, the operation mode signal is not output to the port of the main controller 141. This is also the case when the connection terminal 230 is in contact with the fourth connection pattern 164. Therefore, when the operation mode signal is not received, the control unit 140 turns off the imaging unit in operation, so that both the DSC and the DVC imaging units 221 and 222 do not operate.

At this time, assuming that the first to fourth connection patterns 161 to 164 are provided at an interval of 90 degrees, when the connection terminal 230 is positioned at an angle of 45 degrees up and down relative to the left side of the A axis, the DSC imaging unit ( When the 221 is positioned at an angle of 45 degrees up and down with respect to the right side of the A axis, the DVC imaging unit 222 operates, and is positioned at an angle of 45 degrees left and right with respect to the top of the Y axis, or left and right with respect to the bottom of the Y axis. If it is positioned at a 45 degree angle, neither imager will operate. As described above, the image capturing unit is turned off at an angle of 45 degrees left and right with respect to the Y axis, and the user sets the zoom function so that the DSC and DVC lens units 211 and 212 protrude out of the composite image capturing unit 200. This is to prevent the lens units 221 and 222 from colliding with the main body 100 when the composite image pickup unit 200 is rotated.

FIG. 10 is a diagram provided for describing another example of the mode sensing unit 300 of FIG. 2. Referring to FIG. 10, a mode switch unit 310 is provided on a surface where the composite image pickup unit 200 is in contact with the main body 100, and the mode switch unit 310 has a DSC mode switch 311 and a DVC mode switch ( 312). The DSC mode switch 311 is connected to the first port of the main controller 141, and the DVC mode switch 312 is connected to the second port of the main controller 141. When the composite image pickup unit 200 rotates with respect to the main body, the mode switch unit 310, the DSC mode switch 311, and the DVC mode switch 312 provided in the composite image pickup unit 200 also rotate together.

The DSC mode switch 311 is rotatable in the range of d1 and d2. When the DSC mode switch 311 is positioned in the d1 range (45 degrees to the left and right with respect to the lower side of the Y axis), the binary signal '1', which is a DSC operation mode signal for operating the DSC imaging unit 221, is controlled by the main control unit 141. ) And a binary signal '0' is output to the second port of the main controller 141. On the other hand, the DVC mode switch 312 can be rotated in the range d3 and d4. When the DVC mode switch 312 is positioned in the d3 range (90 degrees to the left of the lower side of the Y axis), the binary signal '1', which is a DVC operation mode signal for operating the DVC imager 222, is the main controller 141. ) And a binary signal '0' is output to the first port of the main controller 141.

11 is a flowchart provided to explain a composite photographing method according to the present invention. Referring to FIG. 11, the main controller 141 determines an operation mode based on the operation mode signal received from the mode selection switch unit 300 (S500).

If it is determined in step S500 that the DSC operation mode, the display unit 150 displays the fact that the composite image pickup device is currently operating in the DSC operation mode and information on the DSC operation mode to inform the user (S511). Then, the DSC image pickup unit 221 photoelectrically converts the optical image formed through the DSC lens unit 211 into an electrical signal and transmits it to the DSC signal processor 101 (S512). The DSC signal processing unit 101 compresses the signal into a JPEG format signal (S513).

The main controller 141 determines the recording mode based on the recording mode signal received from the recording medium setting unit (S514). If it is determined in the memory recording mode in step S514, the main control unit 141 detects whether there is a still image shooting execution command from the shooting switch unit (S5151). When the still image photographing execution command is detected in step S5151, the still image signal is stored in the memory 121 (S5161). On the other hand, when it is determined in the magnetic tape recording mode in step S514, the main controller 141 detects whether there is a still image shooting execution command from the shooting switch unit (S5152). When the still image photographing execution command is detected in step S5152, the still image signal is stored in the magnetic tape 122 (S5162).

On the other hand, if it is determined that the DVC operation mode in step S500, the display unit 150 displays the fact that the composite image pickup device is currently operating in the DVC operation mode and the information on the DVC operation mode to inform the user (S521). The DVC image capturer 222 photoelectrically converts the optical image formed through the DVC lens unit 212 into an electrical signal and transmits the converted optical image to the DVC signal processor 102 (S522). The DVC signal processor 102 compresses the signal into a DV format signal (S523).

The main controller 141 determines the recording mode based on the recording mode signal received from the recording medium setting unit (S524). If it is determined in the memory recording mode in step S524, the main control unit 141 detects whether there is any one of the still image and moving image photographing execution command from the photographing switch unit (S5251, S5253). Here, when the still image shooting execution command is detected, the still image is stored in the memory 121 (S5261). When the moving image shooting execution command is detected, the moving image is stored in the memory 121 (S5263).

On the other hand, if it is determined in the magnetic tape recording mode in step S524, the main controller 141 detects whether there is any one of the still image and moving image photographing command from the photographing switch unit (S5252, S5254). Here, when the still image shooting execution command is detected, the still image is stored on the magnetic tape 122 (S5262). When the moving image shooting execution command is detected, the moving image is stored on the magnetic tape 122 (S5264).

As described above, according to the present invention, by storing the image photographed by the first and the second image pickup unit respectively independently driven to any one selected from the first and second recording media, the user imaged on the desired recording medium It can be selectively saved, and also prevents the problem that the precious video data recorded in advance is deleted.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
