4 is a flowchart illustrating an image reproduction method of an image processing apparatus according to an exemplary embodiment of the present invention.

It is determined continuously whether a long play button input has occurred (S100). In FIG. 4, an example of a hotkey for entering a slideshow is to press and hold the play button for a predetermined period of time, for example, 2 seconds or more. This makes it possible to easily enter the slide show even without additional buttons. However, the concept of the hotkey of the present invention is not limited thereto, and a person skilled in the art will understand that a hotkey other than the play button may be implemented to enter the slideshow.

When the long play button is input, a slide show of the stored image is performed (S102).

Conventionally, a slide show was performed by entering a play mode by entering a play button, entering a menu by pressing a menu button (FIG. 3), moving to a slide show menu, and selecting a slide show execution.

However, in the digital camera to which the present invention is applied, a slide show can be immediately performed on an image recorded on a storage medium such as a memory card by a hotkey input dedicated to entering a slide show, for example, a long play button input.

5 is a flowchart for explaining a preferred embodiment of the step S102 shown in FIG.

When entering the slide show mode by the long play button input, first, it is checked whether the memory card is mounted (S200). Step S200 is performed in the case of a digital camera using a removable memory card as an image storage medium. If the image processing apparatus using the built-in memory, such as flash memory, step S200 may be omitted.

When the memory card is mounted, it is checked whether or not an image for performing the slide show exists in the memory card (S202).

If the image exists, the slide show setting value is read (S204). The setting value of the slide show can be set, for example, on the setting menu shown in FIG.

A slide show is performed according to the set value (S206).

It is determined whether to end the slide show (S208). For example, the slide show can be terminated when a key input for releasing the slide show occurs.

As the series of operations shown in FIG. 5 are automatically performed, when a hotkey dedicated to entering the slideshow is input, the slideshow may be immediately performed on the image recorded on the storage medium.

6 shows an example of setting values of a slide show. The user may select a slideshow setting menu and set an interval, repeat, and effect as illustrated in FIG. 6.

Here, the interval refers to the interval of image playback of the slideshow. In the figure, it means that the slide show is performed every three seconds.

Repeat determines whether to automatically restart the slideshow after playing the entire stored image.                     

The effect lets you choose a special visual effect that is displayed in the middle of the slideshow while the previous image disappears and the next image appears. Such visual effects include, for example, an effect in which an image gradually appears, an effect in which the image flies from the upper left, and the like.

FIG. 7 is a flowchart for explaining a preferred embodiment of step S206 illustrated in FIG. 5.

If it is determined that the menu key is input during the slide show (S300) (S302), the slideshow is stopped and the current image conversion menu items are displayed (S304). 6 illustrates image conversion menu items displayed by step S304, which will be described later.

If any one of the displayed image conversion menus is selected by the user's operation, the selected menu item is processed (S036).

Although not shown in the drawing, step S302 may be performed by two operations, a key input for instructing to pause the slide show and a menu key input. Although not shown in the drawing, if a key input indicating a resumption occurs after step S302, the slideshow may be re-run regardless of execution of steps S304 and S306. In this case, the stop / replay input may be implemented by one button.

The embodiment of FIG. 7 is based on the premise of entering the slide show by inputting the hot key (long button) of FIG. 2, but is not limited thereto. Apart from entering the slide show by hot key input, a file management function by menu key input during the slide show is another feature of the present invention.

Conventional digital cameras perform a simple function of pause / resume during a slide show. The present invention further provides a function of performing image file management in addition to the conventional slide show function.

FIG. 8 is an example of an image attribute conversion menu displayed by step S304 of FIG. 7. The image attribute conversion menu may include delete, protect, rotate, resize, digital print order format, and DPOF. Contains the cancel menu.

Protect menu is to protect the image from being erased or to release the protected image.

The Delete menu allows you to delete unprotected files.

The rotate menu is a function for rotating a stored picture in a desired direction, for example, right 90 degrees, left 90 degrees, 180 degrees, and the like.

The resolution change menu allows you to change the size of the saved picture to a smaller size.

The DPOF menu is a function to set the number of stored pictures to be printed out immediately. The user can select the DPOF menu, specify the picture to be printed, the number of prints, the print size, and the like to output to the digital printer.

If the user selects the cancel menu, the user exits the image conversion menu and resumes the slide show.                     

FIG. 9 is a flowchart for explaining another preferred embodiment of step S206 shown in FIG. 5.

If it is determined that the left and right arrow keys are input during the slide show (S400) (S402), the direction of the slide show is changed according to the input direction keys (S404).

The slide show starts according to the settings (interval, repetition, effect) illustrated in FIG. When the slide show starts, it can be implemented to start the progress in the forward direction or the progress direction of the last performed slide show.

9 is based on the premise of entering the slide show by inputting the hot key (long button) of FIG. 2, but is not limited thereto. Apart from entering the slide show by hot key input, another feature of the present invention is a function of changing the progress direction of the slide show by inputting a direction button while the slide show is in progress.

10 is a sequence diagram of an image reproduction method of an image processing apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 10, when a slide show is entered by a long button input, an image is repeatedly displayed according to a set value.

If the menu button is input during the slide show, the file menu for changing image properties is displayed.

When the execution of the selected menu (Delete / Protect / Rotate / Resolution / DPOF) is completed, resume the slideshow.

If the left and right buttons are input during the slide show, the slide show direction is changed accordingly.
