Abstract: Provided is a method of controlling a digital photographing apparatus that displays an image of a photograph region on a display panel, generates an image signal of the photograph region in response to signals generated by a shutter release button, and stores image data of the image signal in a storage medium. In an out-focusing mode, the method includes amplifying the blurriness of an out-focusing region by low-pass-filtering image data of regions excluding a setting region within the photograph region.

Abstract: A method for operating a digital photographing apparatus having a touch screen is provided. The method includes: detecting if a menu button for changing shooting information of a digital photographing apparatus has been pressed by a user; displaying icons on a display panel to illustrate which operating modes are currently set; detecting when a user has touched one of the displayed icons and, in response thereto, displaying menu icons that correspond to the touched icon; and, if a menu icon that is desired to be changed is touched among the displayed menu icons, performing a relevant function to change shooting information. According to the above method, shooting information of the camera can be simply changed by operating only the icons displayed on the touch screen. Thus, a unique camera operating method is provided whereby a user can easily and conveniently change and operate shooting information and images.

Abstract: A method of automatically focusing a camera determines a position of a focus lens where an amount of a high frequency in an image signal is a maximum. The amount of a high frequency included in an image signal is measured at intervals of multiple focus motor steps. Three of the measured positions (x1, x2, x3) and their corresponding measured high frequency amounts (y1, y2, y3) are identified, where y2 is the largest of the measured high frequency amounts, and x1 and x3 are the nearest measured positions on either side of x2. A quadratic function f(x) is determined for the high frequency amount with respect to the focus lens position x. A position at which a derivative ? f ? ( x ) ? x of the quadratic function f(x) is zero, is determined to be the position corresponding to maximum high frequency amount. Thus, the driving time of the focus motor can be reduced.

Abstract: In a method of controlling an adaptive menu of a digital camera, at least two menu items are sequentially displayed according to a set display order. An initially active menu item from among the displayed menu items is activated. A user selects a desired menu item. At least one of either the display order of the menu items or the initially active menu item is set according to the number of uses of each of the menu items.
