A maskless exposure apparatus includes a light source, an optical head including a light modulator and an optical system, and reflecting light from the light source to radiate the light to a substrate to be exposed, a stage supporting the substrate and moving the substrate in a scanning direction, where the substrate is rotated such that a reference line of the substrate is at a first angle with respect to the scanning direction, and an optical head rotating unit rotating the optical head. When patterns are formed on the substrate in a direction of a first row and an nth row that is substantially perpendicular to the reference line, the first angle is set such that illuminations accumulated, by a beam spot array, in first portions and second portions on the substrate respectively corresponding to the patterns of the first row and the patterns of the nth row vary.

A photographing apparatus, and a photographing method thereof. The photographing method of the photographing apparatus determines if an instruction to photograph is input, and if the instruction to photograph is input, displays a live view by using a first data output from a first pixel group included in an image sensor, and combines a second data output from a second pixel group included in the image sensor with the first data and generates a photographed image, and stores the generated photographed image. Accordingly, the user is continuously provided with the live view even after photographing. Specifically, in continuous photographing, since the user is provided with the live view through which he or she can check the moving subject of photography, the user is enabled to compose images as he or she wishes.

Apparatus and method to provide a live view while photographing an image

An image forming apparatus is provided that easily allows for removal of paper jams, reduces space for disposing a locking means of a cover, and saves production costs relative to the locking means of a cover.

Disclosed are an apparatus and a method for controlling a correct position of opening and closing a sub-body (folder) in an automatic foldable mobile communication terminal. A sensor means is arranged in one end of a main-body and the sub-body, for detecting a fully open status or a fully closed status of the sub-body. A sub-body opening and closing drive unit opens or closes the sub-body by activating a drive motor. A current sensing unit is coupled to a control unit for sensing an amount of motor drive current applied to the sub-body drive motor. The control unit measures the motor drive current from the current sensing unit upon an enabling of an automatic opening or closing operation of the sub-body, and then discontinues to drive the sub-body drive motor when the measured amount of the motor drive current is larger than a predetermined current threshold and the sensor means senses either one of a fully open status or a fully closed status.
