As shown in (c), the I / F circuit 30 of the printer 301
2 is a structure capable of infrared communication, the camera body 101
The configuration may be such that the printer and the printer 301 are directly connected by wireless.

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

[1] Input of drawing information To input drawing information, the CPU 113 executes the drawing information maintenance processing program stored in the MEM 114, and the drawing information is input through the liquid crystal monitor 102 and the operation display unit 116. It is done by

FIG. 3 shows a flow chart of the drawing information maintenance processing. When the drawing information maintenance processing mode is designated through the operation display unit 116, the corresponding program is executed by the CPU 113.

First, the liquid crystal panel 1 of the liquid crystal monitor 102.
The maintenance mode selection screen is displayed in 19 and "1
The user is prompted to select a desired maintenance mode from "input", "2 record", "3 delete", and "4 end", and when the user selects the desired maintenance mode, the process proceeds to the next step according to the selected maintenance mode (S30).
1). Here, input indicates a process of newly inputting drawing information, recording indicates a process of storing the input drawing information in the MEM 114, deletion indicates a process of deleting the drawing information stored in the MEM 114, and end indicates a drawing. This shows the end of the information maintenance processing mode.

When "4 end" is selected in step S301, the process ends.

In step S301, "1 input", "2"
If either "record" or "3 delete" is selected, the process proceeds to step S302, the corresponding process 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 is prompted to input drawing information in accordance with 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 FIG.
As shown in (b), the drawing information can be easily input by displaying the resolutions of several types of printers or the paper size / direction of the printers and allowing the user to select and input.

However, in this embodiment, the offset value and the magnification are automatically selected by the CPU 113 for the following reasons. That is, in the present invention, the main purpose is to directly transfer image data to an image forming apparatus such as a printer without the intervention of a computer, in other words, how to easily transfer the image data from the camera body 101 to the printer 301. Since it is intended, there are several offset values O
The X, OY and the magnification n are prepared in advance in the MEM 114 to simplify the calculation in the layout determination process described later.

FIG. 5 shows the relationship among 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 photographed by the digital still video camera (width W X pixel of height H) is fixed, and the recording paper size, recording paper direction, and resolution are fixed (known) at the time of output request. Therefore, since the printing range on the recording paper at the pixel level is already known, the offset values OX and OY are first selected, and the size nW × nH (printer 3
The layout determination process described later can be easily performed by calculating whether the image area output at 01) falls within the print range.

Next, when "2 record" is selected in step S301, the drawing information input by "1 input" is stored in the MEM 114. When "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 shows a flowchart of print processing by the image data output system of the digital still video camera of the first embodiment. In the figure, the process on the digital still video camera side is described as "DSVC:", and the printer 3
The processing on the 01 side is described as “printer:”.

When the print processing mode is selected on the operation display unit 116 when executing the print processing, the CPU 11
3 executes the flowchart of FIG.

First, the user selects the desired output image using the liquid crystal panel 119 and the operation display section 116 (S
601), and when a print request is subsequently input (S60)
2), the CPU 113 controls the printer 30 via the communication I / F unit 122, the I / F device 201, and the I / F circuit 302.
It communicates with the control unit 305 of No. 1 to determine whether the printer 301 is ready for preparation (S603).

If the printer 301 is not ready, the printer 301 shifts the printer 301 to the usable state (S604). On the other hand, if the preparation is OK, it is determined whether or not the drawing information is stored in the MEM 114 (S605), and if it is not stored, the drawing information maintenance process is executed (S606). in this case,
The user inputs drawing information according to the flowchart shown in FIG. 3 and records it in the MEM 114.

If the drawing information is stored in the MEM 114 in step S605, the image development determination processing of FIG. 7 described later is executed, the image development processing time is predicted from the drawing information, and the digital still video camera prints. 301
It is determined whether or not the image can be followed, and if it is not possible, there is a free space for expanding the image in the memory card 103, and if there is free space, the image is expanded to the memory card 103. If there is no free space, a stop command is output (S607).

Subsequently, it is determined whether or not a cancel instruction is output in the image expansion determination processing (S608), and if the stop instruction is output, the processing is ended as it is. On the other hand, if the stop command is not output, the layout determination process of FIG. 8 described later is executed, the offset value and the magnification are determined from the drawing information, and the pixel clock (synchronization signal) is calculated (S609), and the image is displayed. Printer 301 based on clock
(S610) and the printer 301
The image data expanded to (or while expanding the image data) is transmitted (S611).

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

The digital still video camera repeats step S611 until the transmission of all the image data is completed, and when the transmission is completed, the operation proceeds to step S614 (S614).
613). In step S614, the printer 301
When the end of transmission is input, the recording paper is forcibly ejected and the processing ends. After the transmission is completed, the digital still video camera side also ends the processing.

Here, the image development determination processing 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). If it is possible to follow, the printer 3
Since it can be transferred to 01, the processing is ended as it is. On the other hand, if the image cannot be tracked, 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. From memory card 10
It is determined whether or not there is a free space for expanding the image in 3 (S705).

If it is determined in step S705 that there is free space, the image is developed and converted into data in a state of being drooped to the printer 301 (simple transfer state),
Write to the memory card 103 (S706). When the expansion is completed (S707), the process is ended.

On the other hand, when it is determined in step S705 that there is no free space, the liquid crystal panel 119 displays a replacement instruction of the memory card 103, an image deletion instruction in the memory card 103, and a selection display of stop / continue. , Prompt the user for selection (S708). Here, the operation display unit 11
If stop or continue is selected via step 6, step S7
At 09, it is determined whether or not it is a cancellation. For example, the user may replace the memory card 103 or the memory card 103
After erasing the image inside, if continuation is selected via the operation display unit 116, steps S703 to S70
5 is executed, and it is determined again whether the data can be expanded to the memory card 103. When the user selects the cancel, the 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 uses the MEM1
The drawing information stored in 14 is loaded (S80
1) Determine the print range (width TW x height TH) on the recording paper based on the recording paper size and orientation, set the fixed image area (width W x height H) of the digital still video camera, Specific OX, OY is selected as a candidate (a-th candidate) from several kinds of offset values OX, OY, and then a specific magnification n is selected as a b-th candidate from several kinds of magnifications n (S80).
2).

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

On the other hand, if it is not within the print range on the recording paper in step S803, it is determined whether or not 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, step S804. Then, the process ends.

As described above, according to the first embodiment, the drawing information of the printer 301 is input in advance, and the MEM 11
4, the digital still video camera converts image data to be sent to the printer 301 into image data suitable for the printer 301 based on the drawing information, and uses a synchronization signal suitable for the printer 301.
