Title: Apparatus and method of deinterlacing interlaced frames capable of outputting consecutive two deinterlaced frames
Inventor: JUN BYEONG U
IPC: H04N5/44
Filed: 2002-11-22
Abstract: PURPOSE: A deinterlacing system and method are provided to simultaneously output continuous two deinterlaced frames. CONSTITUTION: A deinterlacing system(200) includes a field buffer(210), a shift buffer(220), a frame generator(230), and a light exchange(240). The field buffer receives and buffers four interfaced fields. The field buffer serially outputs the p-th line data of the first field, the p-th line data of the third field, the p-th line data of the second field, and the (p+1)th line data of the second field, or serially outputs the p-th light data of the second field, the p-th line data of the fourth field, the p-th line data of the third field, and the (p+1)th line data of the third field. The shift buffer receives the output signal of the field buffer, converts the line data serially output from the field buffer into parallel line buffer and outputs the first line data to the fourth line data in parallel. The frame generator generates a deinterlaced frame using the four line data items output from the shift buffer. The line exchange selectively exchanges the output signal of a selector(234) of the frame generator and the output signal of a sub-memory(221) of the shift buffer.
