Description

  The present invention relates to an image processing system, an image processing method, a program, and a computer-readable storage medium that stores the program in a computer-readable manner, with a structure in which an image processing unit (camera unit) and a main body unit are mounted and separated. It is about.

  FIG. 7 is a block diagram showing a configuration of a conventional image processing system, that is, a so-called integrated digital camera.

  In FIG. 7, reference numeral 701 denotes a lens group, which may be a fixed-focus lens group or a zoom lens group having a predetermined magnification. Reference numeral 702 denotes an image sensor represented by a CCD, and the number of pixels is determined depending on the resolution. A CCD control unit 703 includes a timing generator (TG circuit) that supplies a transfer clock and various control signals to the CCD 702, a CDS / AGC circuit that performs noise removal and gain adjustment processing on the image signal from the CCD 702, and an analog An A / D converter circuit that converts an image signal into a 10-bit or 12-bit digital signal is provided. From this CCD control unit 703, the analog signal input from the CCD 702 is processed by the CDS / AGC circuit, and the image data digitized by the A / D converter circuit is always 30 screens (frames) per second. Is output. Most of the CDS / AGC circuit and TG circuit are controlled by synchronous serial communication output from the digital camera function IC 704.

  Reference numeral 704 denotes a digital camera function IC, which performs image processing such as white balance adjustment, shutter speed and exposure control on the image data from the CCD control unit 703, converts it into a digital signal in Y / Cb / Cr format, and converts it into JPEG. A representative compression process is performed, and the photographed image is stored in a CF card 707 as storage means.

  Connected to the digital camera function IC 704 are a work memory 705 which is a memory for a work area necessary for performing the above processing, a CF card which is a storage means, and a key SW group 708 such as a shutter SW and a mode switching SW. Has been. In many cases, an output for display of the digital camera function IC 704 is NTSC, and an NTSC output IC 708 is connected to output the signal to a display device 709 as display means. A program memory 710 includes a flash memory, a mask memory, and the like in which a program for the digital camera function IC 704 is stored. Reference numeral 711 denotes a lens driving motor unit that performs focus control and zoom control of the lens group 701.

  Next, display signal output of the digital camera function IC will be described. Here, an internal operation in a mode in which only the image is displayed on the display device 709 without pressing the shutter SW in the key SW group 706, which is usually called a finder mode, will be described.

  In the still image shooting mode or the moving image shooting mode, the digital camera function IC 704 outputs data for setting the finder operation to the CCD control unit 703 by synchronous serial communication. Upon receiving the data, the CCD control unit 703 outputs various control clocks corresponding to the finder mode to the CCD 702. In this state, the light information of the subject captured from the camera lens 701 is converted into an electrical signal by the CCD 702 with various control clocks output from the digital camera function IC 704 through the timing generator (TG).

  The electrical signal output from the CCD 702 is converted into a digital signal through the CDS / AGC & AD circuit of the CCD control unit 703 and input to the digital camera function IC 704. Inside the digital camera function IC 704, parameters for each processing such as AE, AF, AWB, etc. are calculated from the digital signal of the image input at a timing of 30 screens (frames) per second, and new parameters are converted into the digital camera function. By resetting the register in the IC 704, sending it back to the CCD control unit 703, and controlling the lens driving motor unit 711, an optimum state for taking an image is set.

  Also, when the digital camera function IC 704 reduces the pixel size necessary for displaying the input image and writes the display data in the display memory area on the work memory 505, the image data written by the image display unit is displayed as the display image. Output as data. This display image data is normally output at a digital camera function IC with a digital output of 13.5 MHz per dot, approximately 640 x 480 dots per screen, 30 frames per second, and YCbCr 4: 2: 2. The

  However, since the NTSC system is the mainstream display means in ordinary digital cameras, most digital camera function ICs are configured to display image data not only with digital output but also with NTSC signals. In the case of the NTSC signal, an image of about 30 frames per second on an original screen of about 720 × 480 is divided into an EVEN frame and an ODD frame and output as about 60 frames per second at about 720 × 240 dots. The NTSC output IC 708 can display an image on the display device 709 by inputting the NTSC signal and outputting a signal for displaying the image on the display device 709.

Next, the operation of each control IC during still image recording will be described.
When the shutter SW is pressed in the still image shooting mode, the digital camera function IC 704 stops the viewfinder operation and transfers data for instructing the mode for taking in all the pixels of the CCD to the CCD control unit 703 by synchronous serial communication. . Normally, the image data output during the viewfinder operation is controlled by the CCD control unit 703 so that the image data output from the CCD 702 is thinned out to about 1/4 in the vertical direction. Control is performed so that the pixel data of all the CCDs 702 are output in several frames.

  The output all pixel data is adjusted in analog level by the CCD control unit 703 and input to the digital camera function IC 704. The digital camera function IC 704 develops data for all pixels on the work memory 705, performs various image processing, then writes JPEG compression and JPEG compressed files to the work memory 705 in the JPEG processing unit, and then The same compressed data is read from the work memory 705 and stored in the CF card 707. After completing the writing to the CF card 707, the digital camera function IC 704 returns to the finder mode again.

Next, the operation of each control IC during moving image recording will be described.
The so-called motion JPEG method has become the mainstream for moving image shooting in conventional digital cameras. When the shutter switch is pressed in the moving image recording mode, the image data input to the digital camera function IC 704 is written into the display memory area as display image data, in the same manner as the data flow in the finder mode described in the above display signal output. It is.

  At the time of still image shooting, JPEG compression processing is performed on the data for all pixels on the work memory 705. At the time of motion JPEG processing, JPEG processing is performed on the display image data written in the display memory area. Do. In the JPEG processing unit inside the digital camera function IC 704, the display image data is converted into a JPEG file, temporarily recorded in the work memory 705, and then transferred to the CF card 707. This process is performed continuously while the shutter switch is pressed, but since the transfer speed to the CF card 707 is limited, the image size is VGA (640 × 480) or less and the frame rate is 15 fps or less. Under the conditions, the continuous shooting time is limited to 15 seconds.

  So far, the conventional integrated digital camera has been described, but most of the separation type digital cameras having a configuration in which the camera portion and the main body portion are separated are separated by the broken line portion 712. In this case, the signal line between the CCD control unit 703 and the digital camera function IC 704 is a signal for synchronous serial communication for controlling the CCD control unit 703, a slight timing control signal, and a digital signal output in parallel from the CCD control unit. This is a control signal for recording means (hereinafter referred to as memory) 714 composed of an EEPROM, a flash memory, or the like for recording image data and information relating to the camera unit.

  When the operator attaches the camera unit to the main unit and inputs the power SW, the digital camera function IC 704 starts initial processing for image shooting. During the initial process, the digital camera function IC 704 communicates with the memory 714, reads the identification code recorded in the memory 714, and determines whether or not the camera unit is genuine. If it is determined that the camera is legitimate, an initial process of the camera unit is executed. After the initial process is completed, a mode selection screen such as an image shooting mode, an image reproduction mode, and a system setting mode is displayed on the display device 709. When the operator selects an image shooting mode using the key SW 706 and presses the key SW 706 for mode setting, the digital camera function IC 704 performs a camera mode switching process, and then displays a viewfinder on the display device 709. Display is done and the camera is ready for shooting.

  There is also a digital camera that has a configuration in which only the display portion is separated, and the display content is controlled by an infrared signal when the display means is not attached, and by an electrical signal via the connector when the display means is attached. . In this case, when the display device 709 and the main body are separated by the broken line portion 713 and the display device 709 is separated from the main body, the digital camera function IC 704 is displayed on the display device 709 with infrared rays output from the infrared output IC 714. Output a signal. When the display device 709 is mounted on the main body, the mounting detection unit 715 outputs a mounting detection signal to the digital camera function IC 704. The digital camera function IC 704 to which the attachment detection signal has been input stops the display signal output from the infrared output IC 714 until then, and outputs the display signal based on the electrical signal from the NTSC output IC 708. In such a case, regardless of connection, the contents and applications to be displayed are the same, and the control signal output means is merely changed.

  With the recent spread of the Internet, a CCD camera that can be connected to a personal computer (PC) via USB or IEEE1394 and a camera module that can be connected to a PDA via a CF card interface are becoming common. Most of these cameras are equipped with CCDs ranging from QCIF size (176 × 144) to VGA size (640 × 480) at most, and the main purpose is that of a network meeting using the Internet. It is used for simple image recording for WEB posting. When a specific application is started on the PC, if the camera module is connected, the captured image is displayed on the application window. If the camera module is not connected, the camera is not connected. Is simply displayed on the application window.

  However, in the conventional image processing system in which the camera unit and the main unit are separated, one is selected from a plurality of camera units having various types of lenses and variations depending on the number of CCD pixels. When the camera unit is replaced, the camera unit settings return to the default settings, and it is necessary to reset the settings such as the image size and compression ratio before shooting. If shooting is started immediately after the camera unit is mounted on the main body and the power is turned on, an unintentional image is shot. This problem occurs similarly even when the identification code can be recorded in the camera unit.

  The present invention has been made in view of the above-mentioned problems, and when the selected image processing unit (camera unit) is connected to the main body to perform shooting, shooting that is not intended by the operator is performed. The purpose is to avoid.

  In order to achieve the above object, the present invention has a structure in which an image processing unit for processing an image and a main body are mounted and separated, and one of the plurality of image processing units for one main body. A connecting means for selecting and attaching one of the two, joining means for joining, a communication means for the main body part and the image processing part joined by the joining means to communicate with each other, and the image processing by the joining means When the main unit and the main unit are joined, the communication unit communicates with the setting unit to notify the main unit of the settable items of the image processing unit. A setting content comparison unit that compares the settable item notified by the notification unit with the setting content for the image processing unit that is already recorded in the main body unit, and the setting result comparison unit Inside Approximate value setting means for setting a more approximate value when it is determined that there is a difference between the settable item notified by the notification means and the setting contents recorded in the setting recording means. An image processing system or the like is provided.

  Specifically, in an image processing system having a structure in which an image processing unit (camera unit) for processing an image and a main body unit are mounted and separated, first, when the power is turned off or the camera unit is separated The setting related to the camera unit performed by the operator on the main unit is recorded. When the camera unit is installed in the main unit or when the camera unit is installed when the power is turned on, the main unit and the camera unit perform communication processing, and the camera unit having any function is installed. The main body part determines whether or not. When it is determined that the same camera unit as that at the time of the previous OFF or separation is attached, the recorded setting is set for the camera unit, while a camera different from that at the time of the previous OFF or separation is attached. When it is determined that the setting has been made, the main body automatically determines the setting closest to the recorded setting and sets the setting for the camera unit.

  In addition, when it is determined that a camera different from that at the time of the previous OFF or separation is attached, a display content that allows the operator to determine the changed setting content on the display unit is output. In addition, when it is determined that a camera different from that at the time of the previous OFF or separation is attached, a mode setting screen is displayed on the display unit so that the operator can determine the changed setting. Further, when it is determined that a camera different from that at the time of the previous OFF or separation is mounted, a warning sound is generated on the display unit so that the changed setting can be determined by the operator.

  According to the present invention, when the selected image processing unit (camera unit) is connected to the main body for shooting, the settable items of the image processing unit and the image processing unit already recorded in the main body Compared with the setting contents for, and when it is determined that there is a different part, a more approximate value is set, so that unintended shooting by the operator can be avoided.
