First recorded.

When the menu button 16 is pressed, the mode shifts to the menu mode, and the menu corresponding to the number is displayed on the LCD 15 along with the number, such as "1: composition ratio setting". At this time, the predetermined menu is highlighted ( ST12). In this menu mode, pressing the down button 17a or the up button 17b (hereinafter collectively referred to as the "selection button 17") switches the highlighted menu, and pressing the release button 13 causes the inverted menu to be displayed. The mode is switched to the current menu. Pressing the selection button 17 selects a menu, and pressing the release button 13 shifts to the menu mode. The same applies to the selection of a selected image and the setting of the composition ratio in the submenu selection described later. is there.

Then, the selection button 17 is pressed to select "1: composition ratio setting", and the release button 13 is pressed to shift to the composition ratio setting mode (ST14). When the mode shifts to the combination ratio setting mode, the display screen is switched to the combination ratio setting mode display screen, and submenus “1: composite image selection”, “2: combination ratio setting”, and “3: shooting” are displayed on the LCD 15 and , A predetermined submenu is highlighted (ST16).

The mode is shifted to the composite image selection mode in which the selection button 17 can be pressed to select the selected image (ST1).

Now that the shooting preparation has been completed, "3: shooting" is selected from the above-described submenu displayed on the LCD 15, and the mode is shifted to the shooting mode (ST18).

When the release button 13 is pressed, shooting is performed in the state set as described above (ST40). When this photographing is completed, only the current image is recorded on the memory card at the m-th position shown in FIG. 6 described above, and an order describing the combination destination file name indicating the selected image n and the combination ratio data indicating the combination ratio. File is created automatically,
The order file is recorded at a predetermined address of the same memory card so as to correspond to the m-th image. With this, if the memory card is taken out of the camera 10 and brought into the lab, and the print order of the m-th image is ordered, the device for reading the order file provided in the lab is used.
The selected image n to be combined and the combination ratio data are read from the order file corresponding to the th image, and the read selected image n and the current image recorded at the mth position are read from the memory card, and according to the combination ratio. Selected image n
And the m-th image are combined and printed. By recording only the m-th current image in this way, it is possible to have only the m-th current image printed without performing image synthesis. The m-th image to be recorded on the memory card may be not only the current image but also a composite image itself synthesized by the camera 10. Then, the composite image can be printed without referring to the order file, and the lab does not need to have a special device for reading the order file.

The above explanation is based on the selection button for setting the combination ratio.
Although the description has been made with reference to FIG. 17, the present invention is not limited to this. For example, a combination ratio setting lever 30 as shown in FIG. 7A is provided in the camera 10, and the combination ratio is set by sliding the lever 30. You may do so. FIG.
As shown in (B), there are provided a selected image level setting lever 31 for setting the output level of the selected image and a current image level setting lever 32 for setting the output level of the current image. May be individually set, and the images may be combined at the set level.

The above description has been made on the case where no means for adjusting the output level of the composite image is provided. Therefore, in the above-described camera 10, the output level of the synthesized image cannot be adjusted unless the output levels of the selected image and the current image are individually set and the images are synthesized at the set level. Was.

The digital still camera according to the present invention may further include output level adjusting means. For example, as shown in FIG. 8, if an output level adjusting unit 40 is provided between the image synthesizing unit 26 and the display unit 27, and the level of the output signal S3 of the image synthesizing unit 26 is adjusted,
The output level of the composite image can be easily adjusted. And for this adjustment, for example, FIG.
As shown in the figure, the same composition ratio setting lever as in FIG.
An output level adjustment lever 33 may be provided next to 30 and a mode for adjusting the output level of the composite image may be added in step 18 in the above example.

The output level adjusting means 41 is provided between the synthesizing ratio setting means 25 and the image synthesizing means 26 as shown in FIG. 9 without being limited to the example shown in FIG. After the adjusting unit 41 further adjusts the set combining ratio of each image, the adjusted combining ratio may be input to the image combining unit 26.
