The present invention relates, in general, to an apparatus and method for converting interlaced field image data into progressive image data in image processing techniques and, more particularly, to an apparatus and method for performing intra-field interpolation for a de-interlacer, which calculates a direction in which pixel values are changed using the variations and correlations between the pixel values of the regions on two lines in one field, and outputs an interpolated value depending on the direction, thus enabling a field to be interpolated in the change direction.

A filter, in particular, a finite impulse response (FIR) filter having a variable data input and output rate is disclosed. The FIR filter includes a first-in first-out (FIFO) architectural buffer, an address generator for circularly generating respective addresses for FIFO of data items and providing the addresses to the buffer, a filter for performing filtering on data items having different rates, which are input from the buffer, and outputting one or more data, and a controller for controlling address generation of the address generator and controlling transfer paths of data items for filtering of the filter. It is possible to variably control the input and output rate of filtering data by the FIR filter.

Disclosed is a video restoring apparatus and method thereof enabling to improve a video mode by interpolating field data. The present invention includes the steps of: identifying whether a scene on an image sequence is changed by receiving field data; detecting whether a 3:2 pull-down mode exists in the image sequence; generating a first interpolated frame by interleaving a field to be interpolated and adjacent fields each other when there is the 3:2 pull-down mode; generating a second interpolated frame by de-interlacing the field to be interpolated and the adjacent fields each other when there is not the 3:2 pull-down mode, and selectively outputting one of the first and second interpolated frames.

A video format converting apparatus which optionally converts the sizes of input and output videos includes a mode generator for generating a control signal of required data flow and a clock required for format conversion by determining a format conversion structure after receiving format data of input and output videos, a format converter of which input/output data path is controlled to a corresponding operation mode by the control signal, for independently format converting the input video synchronized with the clock in vertical and horizontal directions, and a plurality of multiplexers for providing proper video to the format converter in accordance with the signal of the mode generator. When various kinds of input videos are format converted to various kinds of output videos, it is possible to reduce the capacity of required hardware and the capacity of the memory. Thus, a minimum memory band width is required.
