The present invention relates to a method and a device for controlling a digital image processing device, and more particularly, to a method and a device for controlling a digital image processing device in which a captured image is displayed on a specific region of an image pickup device or an image display device. .

Typically, the digital image processing apparatus includes all devices that process images of a digital camera, a PDA (personal digital assistant), a phone camera, a PC camera, or the like, or use motion recognition sensors. The digital image processing apparatus receives a desired image through the image pickup device, displays the input image on the image display device, and displays the image on the image display device, and stores the image as an image file according to the user's selection of the image.

In a typical digital image processing apparatus, a desired image is photographed as an image file having a preset size. In this case, the user may select the size only from among already specified sizes. Therefore, the user cannot set the image to any size desired by the user.

In addition, an image of the entire photographing element or the image display element or a predetermined specific region is stored as an image file at the time of photographing. Therefore, the user cannot arbitrarily select a desired region and photograph. In a technique such as division shooting, the user may not photograph by setting an area of a photographing element or an image display element other than a preset divided region.

Therefore, the user cannot capture a region image of various shapes, sizes, and positions, such as to express an image with the top and bottom cut off, or to photograph the image capturing area only in the center.

In the conventional digital image processing apparatus, there is a problem in that the image cannot be set to any size desired by the user, and the user cannot set the desired region of the image capturing device or the image display device.

An object of the present invention is to provide a method and a device for controlling a digital image processing apparatus, by which a user can arbitrarily set a region of an image so as to capture region images of various shapes, sizes, and positions.

The present invention provides a method of capturing an image to be photographed and storing the image as an image file having a preset image size, wherein the image is captured in a preset imaging area of the imaging device; Displaying the captured image on a preset display area of a display element; And storing the captured image in the image size, wherein at least one of the imaging region, the display region, and the image size can be set by a user setting. do.

Preferably, the imaging area and the display area are determined by setting coordinate values of the starting point, width of the area, and height of the area.

Preferably, the image size is reset according to the ratio of the width and the height of the imaging area and the display area.

The display area is an area in which the captured image is to be displayed among all the effective display areas of the display element, and the entire effective image pickup area of the image pickup device corresponds to the total effective display area of the display device, and the image pickup area corresponds to the display area. It is preferable to reset according to the display area.

Another aspect of the present invention provides a control apparatus of a digital image processing apparatus for capturing an image to be captured by the control method of the digital image processing apparatus and storing the image to be stored as an image file of the image size.

According to the present invention, in the digital image processing apparatus, the user can arbitrarily set a region of an image to photograph, thereby capturing region images of various shapes, sizes, and positions.

That is, the user image size menu or the user image area selection menu may be activated by the direction button 21 and the menu-OK button 22, and the user may set desired settings.

Wide angle-zoom button W or telephoto-zoom button T widens the view angle or narrows the view angle depending on the input. In particular, it can be used to change the size of the selected exposure area. In this case, when the wide-zoom button W is input, the size of the selected exposure area is reduced, and when the tele-zoom button T is input, the size of the selected exposure area may be increased.

A digital image signal from the digital signal processor 507 is temporarily stored in a DRAM (Dynamic Random Access Memory) 504. The EEPROM (Electrically Erasable and Programmable Read Only Memory) 505 stores algorithms and setting data such as a boot program and a key input program required for the operation of the digital signal processor 507. In the memory card interface 506, a user's memory card is detached.

The digital image signal from the digital signal processor 507 is input to the display panel driver 514, which causes the image to be displayed on the display panel 25.
