Abstract: Provided is a microwave plasma discharge lamp apparatus which includes a rectangular waveguide having a rectangular shape one end of which is closed and the other end is open and receiving a microwave through an opening to put out linearly polarized microwaves; a discharge lamp; a resonator cavity, formed in a cylindrical shape, one end of which is open, which is disposed to surround the discharge lamp, and which is made of a conductive mesh, thereby allowing the passage of the light from the discharge lamp; and a phase shifter, which has a cross-shaped waveguide opened in a propagation direction of the linearly polarized microwaves, is disposed between the other end of the rectangular waveguide and one end of the resonator cavity, and receives the linearly polarized microwaves from the rectangular waveguide to generate elliptically polarized microwaves in the cylindrical resonator cavity. The elliptically polarized microwaves discharge the discharge lamp.

Abstract: A method of controlling a digital photographing apparatus to enlarge and reproduce an image is provided. The method includes determining whether an instruction is given in an image reproduction mode, dividing the input image into a predetermined number of blocks when it is determined that the instruction is given, enlarging the small image corresponding to a specific block from among the predetermined number of blocks, and displaying the enlarged small image on an entire screen.

Abstract: A digital photographing apparatus and a method of operating an image pickup device reduce generation of smear. The image pickup device includes a matrix of photoelectric converters which generate charges from incident light, vertical transfer paths for reading charges generated in the photoelectric converters and for transferring the read charges in a vertical direction, and a horizontal transfer path for transferring the charges on the vertical transfer paths in a horizontal direction. The method includes: applying vertical and horizontal transfer signals for causing the charges generated in photoelectric converters defining a subset of rows of the photoelectric converters to be read by the vertical transfer paths and to be transferred in the horizontal direction along the horizontal transfer path; and providing a predetermined period of time in which the horizontal transfer signals are not applied to the horizontal transfer path while charges are being transferred to the horizontal transfer path.

Abstract: A method of controlling a digital photographing apparatus to display an image is provided. The method includes obtaining an input image from an image input unit, and displaying, on a display unit, each of a plurality of display regions of the input image to be enlarged as an enlarged image.

Abstract: A method of controlling a digital photographing apparatus in which a portion of an input image is enlarged and displayed as a display image on an image displaying unit so that a user may determine the clarity of the input image. The digital photographing apparatus receiving the input image having a resolution of a first pixel number and displaying the display image on the image displaying unit having a resolution of a second pixel number. The method includes: receiving the input image; and deciding on an enlarged display region that is to be enlarged from the input image, setting the enlarged display region into at least two display images, and continually displaying the display images on the image display unit.

Abstract: A camera operating apparatus and method are provided. The apparatus includes a signal processor for rotating and storing a shot image so that a storage direction of the image shot with the camera rotated 90° or 180° may be a reference storage direction. The shot image is stored in such a way that a storage direction of the image shot with the camera rotated may be the reference storage direction, which provides convenience that a user needs not to rotate the camera to check the shot image when playing the image.

Abstract: A method for operating a digital camera is provided. Particularly, the method provides for increasing image storage space by changing the resolution of a stored image when photographing a new image. The method includes: displaying images stored in the storage space on a thumbnail screen when a menu for changing a resolution is selected; selecting from the images displayed on the thumbnail screen an image whose resolution is to be changed; and changing a resolution of the selected image when the selection of the image is completed.
