DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital camera for recording an image photographed by an imaging device as digital data on a recording medium.

[0002]

2. Description of the Related Art Conventionally, there has been known a digital camera that records an image photographed by a CCD (solid-state imaging device) as digital data on a recording medium such as a memory card or a built-in memory. In a digital camera of this type, when a user presses a shutter button, image data of an image captured by a CCD is converted into digital data and then compressed by a well-known compression method, thereby obtaining compressed image data. Is recorded on the memory card as an image file. At this time, a serial number is assigned to the image file in the order of image capturing.

A digital camera of this type can switch and display a plurality of images recorded on a recording medium by a predetermined number of images, for example, nine images on an LCD (liquid crystal display). FIG. 9 illustrates an example in which nine images displayed on the LCD are switched by an image switching operation by the user. In FIG. 9, the images captured by the CCD are not shown, and the numbers in the figure represent the numbers of the image files. For example,
When the user presses the left arrow key in a state where the images Nos. 1260 to 1268 are displayed on the LCD as shown in FIG.
Images from No. 1262 to No. 1262 are displayed on the LCD. On the other hand, when the user presses the right arrow key,
As shown in (c), images 1266 to 1274 are displayed on the LCD. In this way, the user can display a target image on the LCD by performing an image switching operation while looking at the LCD.

[0004]

By the way, the number of images that can be recorded on a memory card has increased due to the recent development of memory technology.
Some can record about 0 images. However, in the conventional digital camera, as shown in FIG. 9, one image switching operation switches only nine images displayed on the LCD to nine images shifted by six before or after. Therefore, if the target image is an image taken hundreds or more before or after nine images displayed on the LCD, the image switching operation must be performed many times in order to display the image on the LCD. It has to be repeated, the operation is complicated, and there is a problem that it takes time until the image is displayed on the LCD. For example, if the target image is an image taken 300 images after nine images displayed on the LCD, the user must repeat the image switching operation 50 times. Therefore, an object of the present invention is to provide a digital camera capable of displaying a target image on an image display device with a simple operation and in a short time.
