BACKGROUND OF THE INVENTION
The present invention relates to a digital camera and a printing control method using the digital camera.
[0002]
[Prior art]
A digital camera is known in which a digital camera and a printer are directly connected via Bluetooth, USB (Universal Serial Bus), or the like, and a subject image output by the digital camera can be directly printed on the printer. In such a digital camera, generally, print setting information can be designated so as to print a subject image. Here, the time of photographing specifically refers to, for example, the day when the subject image is output, or the date and time. The digital camera generates a print job based on the subject image designated by the user and the print setting information, and outputs the print job to a printer for printing.
[0003]
Among the digital cameras described above, there is known a digital camera that stores in advance layout definition data defining the layout of an image and prints the image in a layout defined by the layout definition data (for example, Patent Document 1). reference.). The electronic camera disclosed in Patent Literature 1 allows a user to select a resume frame or a passport frame as an image, and synthesizes compressed data obtained by compressing an image signal acquired by a photographing unit and an image indicating the selected frame. The printer is printing. Since the electronic camera of Patent Document 1 composites and prints an image showing the selected frame, for example, the frame information (layout definition data) stores a layout such as the size of the frame and the position of the frame on the screen. An image representing the frame is printed at the position specified by the frame information.
[0004]
According to such layout definition data, if the information for printing at the time of shooting is defined, it is possible to perform the combined printing of the shooting time and the subject image in the same manner as the combined printing of the frame image and the subject image. .

[Problems to be solved by the invention]
However, as described above, the conventional digital camera can perform composite printing at the time of shooting without using layout definition data. Therefore, if information for printing the time of shooting is defined in the layout definition data, the time of shooting can be reduced. There is a problem of being printed twice.
FIG. 10 is a diagram illustrating an example of a result 57 printed twice during shooting. In the figure, “2002.1.1” is the time of photographing that is synthesized and printed based on the layout defined in the layout definition data, and “January 1, 2002” is based on the print setting information of the print job. In this case, the image is photographed with composite printing in a predetermined layout.
[0007]
The present invention has been created in view of such a problem, and even when a print job is set to print at the time of shooting, and the shooting time is defined by the layout definition data, the time of shooting can be reduced. It is an object of the present invention to provide a digital camera capable of preventing double printing and a printing control method using the digital camera.
[0008]
[Means for Solving the Problems]

FIG. 7 is a screen transition diagram of screens used for setting a print job. Hereinafter, the flow of processing for setting a print job will be described with reference to FIG.
The image display screen 42 is a screen for displaying a subject image. The image display screen 42 is displayed by performing a predetermined operation. When the selection button 36 (see FIG. 4) is pressed down or up, the subject images stored in the removable memory 20 are displayed in order. When the print button 38 is pressed, a transition is made to the print target setting screen 43.
[0028]
The print target setting screen 43 is a screen for designating selection items for designating a print target. The print target setting screen 43 displays three selection items, “Print this image”, “Print all images”, and “Select and print”, as selection items for specifying the print target. Select one of them. When “print all images” is selected, a plurality of subject images stored in the removable memory 20 are all to be printed. When “Print this image” is selected, the subject image displayed when the printer button 38 is pressed on the image display screen 42 becomes the print target. When “Select and print” is selected, one or more subject images selected on the print instruction screen 44 are to be printed. When setting a print job for continuously printing a plurality of subject images stored in the removable memory 20, “Print all images” or “Select and print” is selected. When “Print all images” or “Select and print” is selected and the print button 38 is pressed, the screen shifts to the print instruction screen 44.
[0029]
The print instruction screen 44 is a screen for instructing printing. The print number display area 47 is an area for displaying the number of prints set for the subject image. When “print all images” is selected and the screen shifts to the print instruction screen 44, 1 is set for the number of prints for all subject images stored in the removable memory 20, and therefore all the print number display areas 47 are displayed. 1 is displayed for the subject image. The number of prints can be arbitrarily changed by a selection button 36. When “Select and print” is selected and the screen changes to the print instruction screen 44, the number of prints is set to 0 for all subject images stored in the removable memory 20, and the user sets the number of subject images to be printed. By setting it to 1 or more, the subject image to be printed is selected. When the menu button 37 is pressed on the print instruction screen 44, a transition is made to a menu screen 45 for setting print setting information such as presence / absence of printing during shooting. When the B button 41 is pressed, the screen transitions to a layout definition data editing screen 46 for selecting layout definition data. When the print button 38 is pressed, subject image information is set so that all images or selected images are to be printed, and processing for causing the printer to print is started.
[0030]
The menu screen 45 is a screen for setting print setting information. The print setting information is information that is uniformly applied to the subject image to be printed.

You can select layout definition data while looking at the screen. When the B button 41 is pressed on the layout definition data editing screen 46, the identification name of the layout definition data displayed on the screen at that time is stored as the identification name of the subject image displayed on the print instruction screen 44 in the association table. Stored in the layout definition data field of the current row. As a result, the subject image, the time of imaging, and the layout definition data are associated with each other.
[0032]
In this embodiment, the subject image, the image capturing time, and the layout definition data are stored in the removable memory 20 in association with each other when the print setting information is set, but are associated with each other when the optical image of the subject is converted into the subject image. May be stored. Specifically, layout definition data may be selected in advance before conversion to the subject image, and stored in association with the layout definition data selected in advance when converted to the subject image.
[0033]
FIG. 1 is a flowchart showing a processing flow of the digital still camera 1.
In S105, the user of the digital still camera 1 presses the shutter button 35 and inputs an instruction to convert the optical image of the subject into a subject image.
In S110, the digital still camera 1 detects that the shutter button 35 has been pressed, and converts the optical image of the subject into a subject image. Specifically, the CPU 25 inputs a predetermined control signal to the scanning control unit 21, scans the electric charge accumulated in the image sensor 13 for a predetermined time, and performs predetermined processing by the CDS circuit 14, the AGC circuit 15, and the A / D converter 16. After the processing, the digital image processing unit 17 converts it into a subject image. Next, the converted subject image is compressed by the compression / expansion processing unit 18 to output the subject image, and the CPU 25 stores the subject image and the time of imaging in the removable memory 20 in association with each other by the reader / writer 19.
[0034]
In S115, the user wire-connects the digital still camera 1 to the printer 2 with a USB cable, for example.
In S120, the user sets subject image information and print setting information to be printed, and presses the print button 38 to instruct the digital still camera 1 to perform printing.
In S125, the CPU 25 generates a print job from the print setting information and the subject image information. At this point, nothing is set in the print job identification information. In the present embodiment, a print job after processing in S130 to S150, which will be described later, is referred to as a print command.
[0035]
In S130, one identification name is acquired from the set subject image information, and whether or not layout definition data associated with the subject image specified by the identification name is defined to be printed at the time of shooting is determined. Determine. Specifically, the determination is made based on whether or not a macro variable is defined in Strings in the DrawStrings line of the script of the layout definition data. When it is defined, the process proceeds to S135, and when it is not defined, the process proceeds to S140.
[0036]
In S135, the CPU 25 sets the subject image to be printed based on the layout definition data at the time of imaging. Specifically, “layout definition data” is designated as the identification information of the line specified by the identification name in the print job.
In S140, the CPU 25 determines whether or not “present” is set for printing at the time of shooting the print setting information. When it is set, the process proceeds to S145, and when it is not set, the process proceeds to S150.
[0037]
In S145, the CPU 25 sets the subject image to be printed based on the print job at the time of imaging. Specifically, “print job” is designated in the identification information field of the line specified by the identification name in the print job.
In S150, the CPU 25 determines whether or not the layout definition data has been determined for all the identification names. If not, the process returns to S130 and repeats the process. If completed, the process proceeds to S155.
[0038]
In S155, the CPU 25 outputs a print command to the printer via the interface unit 28.
FIG. 8 is a diagram illustrating an example of a print command. The print command in the example shown is a command when “Yes” is specified at the time of imaging in the print setting information. As shown in the figure, “layout definition data”, “print job”, etc. are specified in the identification information. Yes.
As described above, the print command is output to the printer 2. When the print command is output, the printer 2 acquires one identification name of the subject image specified by the print command, and the subject image specified by the identification name and the layout definition associated with the subject image. Data is acquired from the digital still camera 1. If “layout definition data” is specified in the print job identification information, the acquired subject image and the captured image are combined and printed based on the layout defined in the layout definition data. At this time, the printer 2 prints at the time of shooting based only on the layout definition data, and ignores the setting even if “Yes” is set for printing at the time of shooting of the print command. If “print job” is specified in the print job identification information, the print data at the time of imaging is preset in the digital still camera 1 as the print data of the subject image generated with the layout defined by the layout definition data. Is printed with a predetermined layout. When nothing is specified in the identification information of the print command, the printer 2 does not print at the time of imaging. The printer 2 repeats the process until printing for all the subject images specified in the print job is completed.
[0039]
Hereinafter, effects of the embodiment will be described.
FIG. 9A is a diagram showing a printing result 55 by the digital still camera 1 according to the embodiment of the present invention.
