    Abstract: PURPOSE: An apparatus and a method for detecting format of an image signal are provided to detect 2:2 pull-down image format by a relatively simple construction. CONSTITUTION: An image signal is inputted to the first and second SAD(Summed Absolute Difference) value calculation units(100,110) and the image signal comprises time continuous plural fields, that is, a current field, a previous field and a next field. The first SAD value calculation unit(100) calculates the first SAD value on the basis of the pixel values of the current field and the previous field. The second SAD value calculation unit(110) calculates the first SAD value on the basis of the pixel values of the current field and the next field. A pattern generation unit(120) compares with the first and second SAD values and then produces check patterns according to the comparison result. A pattern analysis unit(130) stores th check pattern by a field, compares the stored check patterns with the previous stored check patterns and discriminates whether the inputted image signal is 2:2 pull down format image.

    Abstract: PURPOSE: A deinterlacing apparatus and a method therefor are provided to deinterlace a still region and a motion region in a field to be interpolated, thereby improving the quality. CONSTITUTION: A previous field buffer(106), a current field buffer(104), and a next field buffer(102) sequentially store each field of video signals which are consecutively inputted. A zero movement estimator(130) calculates an SAD(Sum of Absolute Differences) value by search units with a standard of the next field stored in the next field buffer and the previous field stored in the previous field. A still region/film mode detector(140) judges whether a predetermined search area is a still region or a source of the video signals is a film based on the SAD value. A three-dimensional interpolation unit(120) adaptively outputs a temporal interpolation value and a spatial interpolation value based on motion information. An adaptive selection unit(150) outputs deinterlacing results based on output of the previous field, the next field, and the three-dimensional interpolation unit according to output signals of the still region/film mode detector.

    Abstract: PURPOSE: A deinterlacing apparatus and method are provided to carry out appropriate interpolation according to a degree of motion and a direction of a boundary in the case of an area having a motion to improve picture quality. CONSTITUTION: A deinterlacing apparatus includes a motion detector(110), an intra-field interpolator(140), an inter-field interpolator(150), and a soft switch(160). The motion detector extracts a degree of motion between a previous field and a next field to calculate a weight. The inter-field interpolator detects a direction value included in pixel values of pixels surrounding a pixel to be interpolated of a current field, and calculates an interpolation value using the surrounding pixel values according to the direction value. The inter-field interpolator calculates an interpolation value that is obtained by averaging pixel values of the previous field and next field corresponding to the pixel to be interpolated. The soft switch mixes the output value of the intra-field interpolator with the output value of the inter-field interpolator using the weight.

    Abstract: PURPOSE: A deinterlacing device and a method therefor are provided to have a quick processing speed by simultaneously calculating an interpolation value and a weight value using an estimation motion vector and selecting one between the interpolation value and the weight value. CONSTITUTION: A motion compensation unit has motion compensation auxiliary units(100a-100n), the first and second multiplexers(200,250) and a motion selecting unit(150). The motion compensation unit performs a motion-compensated temporal interpolation according to a plurality of estimated motion vectors on the basis of a previous field and a next field, generates interpolation values about pixels to be interpolated, and outputs one of the interpolation values as the first interpolation value. A spatial interpolation unit(300) generates the second interpolation value about the pixels using pixel values of peripheral pixels of the pixels to be interpolated. An output unit(350) mixes the first interpolation value and the second interpolation value using a certain weight value, and outputs the mixed interpolation value.

    Abstract: PURPOSE: A system and method for detecting a motion are provided to detect a moving region and a still region easily and rapidly while preventing the generation of a spurious still region in the current field to be interpolated. CONSTITUTION: A motion detection system includes a motion detection part(100), a motion counter part(150), a motion counter buffer part(200), and a moving expansion part(250). The motion detection part sequentially receives a plurality of continuous fields and detects a motion information value representing whether there is a motion for each block/pixel of the currently received field. The motion counter part corrects motion information value for each pixel/block, stored in the motion counter buffer part, according to the motion information value detected by the motion detection part. The moving expansion part expands a motion information value from a moving pixel to adjacent pixels using the motion information value stored in the motion counter buffer part.
