The noise rejection unit rejects noise in current digital image data and previous digital image data at a same pixel position as in the current digital image data. The comparator compares the current digital image data and the previous digital image data of which noises are rejected within a reference value, changes the current digital image data based on a comparison result, and outputs a result indicative thereof.

Abstract: A method of controlling a display apparatus displaying a picture according to an input video signal including a horizontal synchronous signal and a vertical synchronous signal includes setting one or more exclusive display modes, setting whether to apply an auto-adjustment function to the video signal, determining a display mode of the video signal according to the horizontal and vertical synchronous signals when the auto-adjustment function is set to operate, and performing the auto-adjustment function when the determined display mode is not equal to any one of the one or more exclusive display modes. The display apparatus and the control method thereof selectively perform the auto-adjustment function according to the display mode of the input video signal.

Abstract: An apparatus and a method that controls a position of a caption. The apparatus includes: a caption processing unit, which identifies a non-signal area (B) including the caption using a control signal, identifies an image data area (A having the same size as the non-signal area (B), on a screen, and displays caption data of the non-signal area (B) on the image data area (A); a controller, which outputs a control signal positioning the captions to be lost in an enlarged presentation mode on the screen; and a signal processing unit, which performs image signal processing so that the caption data is displayed with predetermined images on the image data area (A).

Abstract: A display apparatus to store a broadcasting signal or a video signal and/or an audio signal in an external storage medium, and reproduce signals from the external storage medium includes a receiving processor, a controller, and an output unit. The receiving processor receives a video signal and/or an audio signal. The controller stores a video signal and/or an audio signal received using the receiving processor in the external storage medium in real time, if a user requires storage of the received video signal and the audio signal. The controller reproduces the stored video signal and/or audio signal from the external storage medium if the user requires reproduction of the video signal and/or the audio signal stored on the external storage medium. The output unit outputs the reproduced video signal and/or audio signal.

Abstract: Disclosed is a method for manufacturing refined fish oil by introducing a novel process into a phospholipid-deprived fish oil which is obtained by mixing fish oil with water and a monosodium glutamate (MSG) by-product with stirring, fermenting the mixture in the presence of urea, processing the mixture with steam, and centrifuging the mixture to separate water and phospholipids from the fish oil. The method further includes the steps of measuring acid value of the separated fish oil to neutralize the fish oil with NaOH, washing the deaciding fish oil with warm water, and drying the washed fish oil in vacuum; mixing the dehydrated fish oil with powders of earthworm excrement to absorb the fish oil into the powders, subjecting the mixture to reaction at least 30° C. or higher for 0.

The animal feed manufacturing method includes the steps of adding urea to fish oil together with a monosodium glutamate (MSG) by-product and fermenting the fish oil, separately removing water and phospolipid contained in the fermented fish oil, adding quicklime to the separated fish oil and cooling the quicklime-added fish oil via gumming and salting-out processes, and thereby obtaining powdered animal feed using a cooling roller or presser.

Abstract: A high definition image projector is provided for modulating light using an acousto-optic tunable filter according to image signals and projecting the modulated light on a screen. An image is obtained by modulating a light beam by pixel units according to the image to be displayed and directly projecting the modulated light beam on the screen in corresponding pixel units. High quality images can thus be displayed on a large screen. By adopting a high-output light source, a high luminance image can be obtained.
