[Example 1]
FIG. 1 is a block diagram of a digital still video camera and an image data output system of the digital still video camera according to the first embodiment, and is roughly divided into a camera main body 101 and an I / F (interface) device 201 of the digital still video camera. And a printer 301.

  The camera body 101 is connected to a liquid crystal monitor 102 capable of displaying captured images and various information and a memory card 103 for recording the captured images.

  The camera body 101 includes a lens unit 104 including a lens, autofocus (AF), aperture, filter, mechanical mechanism, and a CCD (charge) that converts an image input via the lens unit 104 into an electrical signal (analog image data). Coupling element) 105, A / D converter 106 that converts analog image data input from CCD 105 into digital image data, and digital image data input from A / D converter 106 is divided into color difference and luminance for various processing, IPP (Image Pre-Processor) 107 that performs data processing for correction and image compression / decompression, DCT (Discrete Cosine Transform) 108 that performs orthogonal transformation, which is a process of JPEG-compliant image compression / decompression, and JPEG compliance Huffman encoding / decoding (Huffman Encoder / Decoder) coder) 109, a compressed image and an MCC (Memory Card Controller) 110 for temporarily storing digitalized audio that has been captured from the microphone 111 and recording / reading it to the memory card 103 simultaneously, and a microphone ADPCM (Adaptive Differential Pulse Code Modulation) 112 that performs digital conversion of the voice input by 111 and performs compression / decompression processing, CPU 113 that controls the above-described units, and MEM 114 that is a work memory for the system including ROM and RAM, , A remote control function unit 115 having a remote control reception function, an operation display unit 116 for performing key input of various buttons and switch groups and controlling display of a liquid crystal monitor (a liquid crystal panel 119 to be described later), and supplying power to the above units Battery 117, optical low-pass filter 118, / F201 and a communication I / F unit 122 for communicating with the.

  The liquid crystal monitor 102 includes at least a liquid crystal panel (LCD) 119 and a speaker 120. Reference numeral 121 denotes a battery for the liquid crystal monitor 102.

  The I / F device 201 plays a role of inputting image data or the like from the communication I / F unit 122 of the camera body 101 and transferring it to the printer 301. Therefore, the configuration of the I / F device 201 depends on the configurations of the communication I / F unit 122 of the camera body 101 and the printer 301, and is not particularly limited.

  The printer 301 includes an I / F circuit 302 for performing communication with the I / F device 201, an engine unit 303 including a printer engine, and an operation display unit 304 for displaying and inputting various information. , And a control unit 305 for controlling the above-described units.

  In the first embodiment, the liquid crystal monitor 102 and the operation display unit 116 constitute drawing information input means of the present invention, and the MEM 114 corresponds to the drawing information storage means of the present invention, and the CPU 113, IPP 107, DCT 108, coder 109 and MCC 110. The conversion sending means of the present invention is constituted by the above.

  Further, in the first embodiment, as illustrated in FIG. 2A, a configuration in which cables are connected between the camera body 101 and the I / F device 201 and between the I / F device 201 and the printer 301 is taken as an example. As will be described, as shown in FIG. 2B, the communication I / F unit 122 of the camera body 101 is configured to be capable of infrared communication, for example, and infrared communication can be similarly performed on the I / F device 201 side. A configuration in which the communication unit 202 is disposed and the camera main body 101 and the I / F device 201 are wirelessly connected may be employed. Also, as shown in FIG. 2-3, the I / F circuit 302 of the printer 301 may be configured to be capable of infrared communication, and the camera body 101 and the printer 301 may be directly connected wirelessly.

  In the above configuration, the operation will be described in the order of [1] input of drawing information and [2] print processing by the image data output system of the digital still video camera.

[1] Input of drawing information The drawing information is input by causing the CPU 113 to execute a drawing information maintenance processing program stored in the MEM 114 and inputting the drawing information via the liquid crystal monitor 102 and the operation display unit 116. Is called.

  FIG. 3 shows a flowchart of the drawing information maintenance process. When a drawing information maintenance process mode is designated via the operation display unit 116, the CPU 113 executes the corresponding program.

  First, a maintenance mode selection screen is displayed on the liquid crystal panel 119 of the LCD monitor 102. The user is prompted to select a desired maintenance mode from “1 input”, “2 record”, “3 delete”, and “4 end”. When the desired maintenance mode is selected, the process proceeds to the next step according to the selected maintenance mode (S301). Here, the input indicates a process for newly inputting drawing information, the record indicates a process for storing the input drawing information in the MEM 114, the deletion indicates a process for deleting the drawing information stored in the MEM 114, and the end indicates a drawing. Indicates the end of the information maintenance processing mode.

  When “4 END” is selected in step S301, the processing is ended as it is.

  If any one of “1 input”, “2 record”, and “3 delete” is selected in step S301, the process proceeds to step S302, the corresponding processing is executed, and the process returns to step S301 again.

  For example, when “1 input” is selected, a menu screen for inputting drawing information is displayed on the liquid crystal panel 119, and the user inputs drawing information according to the display. The drawing information to be input includes paper size, paper direction, resolution, magnification, offset value (print start position on recording paper), and the like. Specifically, as shown in FIGS. 4A and 4B, the resolution of several types of printers or the paper size / direction of the printer is displayed, and the user can select and input the drawing information easily. It can be performed.

  However, in this embodiment, the CPU 113 automatically selects the offset value and the magnification for the following reason. That is, the present invention mainly transfers image data directly to an image forming apparatus such as a printer without using a computer, in other words, how easily image data is transferred from the camera body 101 to the printer 301. For this purpose, several types of offset values OX and OY and a magnification factor n are prepared in the MEM 114 in advance to simplify the calculation in the layout determination process described later.

  FIG. 5 shows the relationship between the image area of the digital still video camera, the offset value on the recording paper, the magnification, and the image area output by the printer. As shown in the figure, the image area (width W × height) taken by the digital still video camera is shown. H pixels) are fixed, and the recording paper size, recording paper direction, and resolution are fixed (known) when an output request is made. Accordingly, since the print range on the recording paper at the pixel level is known, the offset values OX and OY are selected first, and the size nW × nH (image area output by the printer 301) with the default magnification n is included in the print range. By performing such calculations, layout determination processing described later can be easily performed.

  Next, when “2 recording” is selected in step S301, the drawing information input in “1 input” is stored in the MEM 114. If “3 delete” is selected, the drawing information stored in the MEM 114 is deleted.

[2] Print Processing by Image Data Output System of Digital Still Video Camera FIG. 6 is a flowchart of print processing by the image data output system of the digital still video camera according to the first embodiment. In the figure, the processing on the digital still video camera side is described as “DSVC:”, and the processing on the printer 301 side is described as “printer:”.

  When executing the print process, when the print process mode is selected on the operation display unit 116, the CPU 113 executes the flowchart of FIG.

  First, when the user selects a desired output image using the liquid crystal panel 119 and the operation display unit 116 (S601) and then inputs a print request (S602), the CPU 113 displays the communication I / F unit 122, I / F. Communication is performed with the control unit 305 of the printer 301 via the F device 201 and the I / F circuit 302, and it is determined whether or not the printer 301 is ready (S603).

  If the printer 301 is not ready, the printer 301 is shifted to the usable state on the printer 301 side (S604). On the other hand, if the preparation is OK, it is determined whether drawing information is stored in the MEM 114 (S605), and if not, drawing information maintenance processing is executed (S606). In this case, the user inputs drawing information according to the flowchart shown in FIG.

  If drawing information is stored in the MEM 114 in step S605, an image development determination process shown in FIG. 7 to be described later is executed, the image development processing time is predicted from the drawing information, and the digital still video camera follows the printer 301. It is determined whether or not it is possible, and if it is not possible to follow, it is determined whether or not there is enough free space in the memory card 103 to expand the image. If there is no capacity, a stop command is output (S607).

  Subsequently, it is determined whether or not a stop instruction is output in the image development determination process (S608). If the stop instruction is output, the process ends as it is. On the other hand, if the stop command is not output, a layout determination process shown in FIG. 8 described later is executed, an offset value and a magnification are determined from the drawing information, and a pixel clock (synchronization signal) is calculated (S609). Synchronization adjustment is performed with the printer 301 based on the clock (S610), and the developed image data (or while developing the image data) is sent to the printer 301 (S611).

  When the image data is input from the digital still video camera, the printer 301 draws an image on the recording paper (S612).

  The digital still video camera repeats step S611 until transmission of all image data is completed, and when transmission is completed, the process proceeds to step S614 (S613). In step S614, when the printer 301 inputs the end of transmission, the recording paper is forcibly discharged, and the process ends. After the transmission is completed, the digital still video camera side also ends the process.

  Here, the image development determination process will be described with reference to FIG. The CPU 113 predicts the image development processing time from the drawing information stored in the MEM 114 (S701), and determines whether the digital still video camera can follow the printer 301 (S702). Here, if it is possible to follow, the image can be transferred to the printer 301 while being developed, so the processing is ended as it is. On the other hand, if it is impossible to follow, the image capacity after expansion is calculated (S703), the remaining capacity (free capacity) of the memory card 103 is calculated (S704), and the image capacity after expansion and the remaining capacity of the memory card 103 are calculated. It is then determined whether there is enough free space in the memory card 103 to expand the image (S705).

  If it is determined in step S705 that there is a free space, the image is expanded, converted into data in a state of flowing to the printer 301 (simple transfer state), and written to the memory card 103 (S706). When the development is finished (S707), the process is finished as it is.

  On the other hand, if it is determined in step S705 that there is no free space, a replacement instruction display for the memory card 103, an image erasure instruction display in the memory card 103, and a display for stopping / continuing are displayed on the liquid crystal panel 119 to the user. Selection is prompted (S708). If cancel or continuation is selected via the operation display unit 116, it is determined in step S709 whether or not the operation is cancelled. For example, when the user replaces the memory card 103 or deletes the image in the memory card 103 and then selects continuation via the operation display unit 116, steps S703 to S705 are executed and the process returns to the memory card 103 again. It is determined whether or not deployment is possible. If the user selects cancel, a cancel command is sent (S710), and the process ends.

  Next, the layout determination process will be described with reference to FIG. First, the CPU 113 loads the drawing information stored in the MEM 114 (S801), determines the printing range (width TW × height TH) on the recording paper based on the recording paper size and direction, and the digital still video camera. A fixed image area (width W × height H) is set, a specific OX, OY is selected as a candidate (a-th candidate) from several offset values OX, OY, and then from several magnifications n A specific magnification n is selected as the b-th candidate (S802).

  Next, when the selected offset values OX and OY are used as the image area size (width nW × height nH) output by the printer 301 determined by the selected magnification n, the print range (width TW × height) (TH), it is determined whether or not (S803). Here, if OX + nW <TW and OY + nH <TH, it is within the printing range on the recording paper, so the layout is completed using the selected magnification n and offset values OX, OY (S804), and the process ends. .

  On the other hand, if it is not within the printing range on the recording paper in step S803, it is determined whether there is a next candidate (S805). If there is a next candidate, the process returns to step S802, and if there is no next candidate, the process proceeds to step S804. The process ends.

  As described above, according to the first embodiment, if the drawing information of the printer 301 is input in advance and stored in the MEM 114, the digital still video camera transmits the image data to be sent to the printer 301 based on the drawing information. Since it is converted into image data suitable for the printer 301 and sent out using a synchronization signal suitable for the printer 301, the image data can be directly transferred to the printer 301 without a computer. Therefore, a computer is not required, and image data of a digital still video camera can be output to a recording sheet with an inexpensive configuration.

[Example 2]
In the digital still video camera of the second embodiment, a plurality of drawing information is stored in the MEM 114 in advance corresponding to the type of printer (here, a connectable printer), and the liquid crystal panel 119 and the operation display unit 116 are used. The desired drawing information is selected, and the CPU 113 converts image data to be sent to the printer 301 into image data suitable for the printer 301 based on the drawing information, and sends it using a synchronization signal suitable for the printer 301. Is. The configuration of the second embodiment is the same as that of the first embodiment, and only different parts will be described here.

First, a plurality of frequently used printer drawing information is recorded on the memory card 103 using an external computer (S901). The recorded memory card 103 is attached to a digital still video camera (DSVC) (S902), drawing information is stored from the memory card 103 to the MEM 114 (S903), and then the drawing information in the memory card 103 is deleted (S903). S904). In this way, drawing information is stored in the MEM 114 in advance.

  FIG. 10 is a flowchart of print processing by the image data output system of the digital still video camera of the second embodiment, which is basically the same as the flowchart of the first embodiment shown in FIG. The process of is shown. In the figure, the process on the digital still video camera side is described as “DSVC:”, and the process on the printer 301 side is described as “printer:”.

  First, when the user selects an image to be output and subsequently inputs a print request (S601, S602), the CPU 113 determines whether the printer 301 is ready and shifts the printer 301 to a usable state. (S603, S604). If the printer 301 is in a usable state (preparation OK), it is determined whether drawing information is stored in the MEM 114 (S605), and if not, drawing information maintenance processing is executed (S606).

  On the other hand, when the drawing information is stored in the MEM 114 in step S605, the name of the drawing information stored in the liquid crystal panel 119 is displayed (S1001), and the user selects the drawing information (S1002). Here, when the user selects drawing information, image development determination processing is subsequently performed (S607), and the subsequent steps S608 to S614 are executed in the same manner as in the first embodiment.

  As described above, according to the second embodiment, drawing information of the printer 301 is stored in the MEM 114 in advance, and by selecting the drawing information of the printer 301 used when performing the printing process, the digital still video camera can Based on the drawing information, image data to be sent to the printer 301 is converted into image data suitable for the printer 301 and sent using a synchronization signal suitable for the printer 301. Therefore, the printer 301 can be directly used without using a computer. Image data can be transferred to Therefore, a computer is not required, and image data of a digital still video camera can be output to a recording sheet with an inexpensive configuration.

  In addition, since the drawing information includes specialized information, a general user may be confused. However, the drawing information of each printer (image forming apparatus) is collectively managed in advance using a computer, via the memory card 103. Since a plurality of images can be loaded into the MEM 114, even when a user who does not have specialized knowledge uses a digital still video camera, the printing process can be easily performed. Further, it is possible to greatly reduce the labor of inputting drawing information.

The process of is shown. In the figure, the process on the digital still video camera side is described as “DSVC:”, and the process on the printer 301 side is described as “printer:”.

  First, when the user selects an image to be output and subsequently inputs a print request (S601, S602), the CPU 113 determines whether the printer 301 is ready and shifts the printer 301 to a usable state. (S603, S604). If the printer 301 is in a usable state (preparation OK), the CPU 113 inquires the control unit 305 of the printer 301 to the printer 301 side and determines whether or not there is a drawing information holding function (S1201).

  If it is determined in step S1201 that the printer 301 side does not have a drawing information holding function, the drawing information maintenance process in step S606 is executed, and the drawing information is input on the digital still video camera side. S614 is executed.

  On the other hand, if it is determined in step S1201 that the printer 301 has a drawing information holding function, the process advances to step S1202. In step S <b> 1202, the control unit 305 of the printer 301 stores the current setting state (drawing information) in the drawing information storage unit 306. On the other hand, the CPU 113 inputs the drawing information stored in the drawing information storage unit 306 from the printer 301 and stores it in the MEM 114 (S1203). Thereafter, the subsequent steps S608 to S614 are executed as in the first embodiment.

  As described above, according to the third embodiment, the drawing information is set in the drawing information storage unit 305 on the printer 301 side, whereby the drawing information can be set easily and quickly. If the format specification of the drawing information is determined, the drawing information can be used from other devices (for example, a computer).
