Image signal scan-converting function and scan-converting method thereof

A method for scan-converting an image signal, the method comprising:

• storing odd pixels of a progressive scan image signal;
• storing even pixels of the progressive scan image signal;
• and
• adding the odd pixels and even pixels to form an odd field and an even field, thus producing an interlaced scan signal.

A scan-converting apparatus for scan-converting image signals, comprising:

• a first storing unit for storing odd pixels of a progressive scan signal;
• a second storing unit for storing even pixels of the progressive scan signal;
• and
• an adding unit for adding the odd pixels and the even pixels read from the first and the second storing units to form an odd field and an even field to produce an interlaced scan signal.

A computer-readable medium having stored thereon instructions for scan-converting an image signal, the instructions comprising:

• a first set of instructions for storing odd pixels of a progressive scan image signal;
• a second set of instructions for storing even pixels of the progressive scan image signal;
• and
• a third set of instructions for adding the odd pixels and even pixels to form an odd field and an even field, thus producing an interlaced scan signal.

A method for forming an interlaced scan image signal from a progressive scan image signal, the method comprising:

• decomposing a progressive scan image signal into odd and even pixels;
• forming an odd field by adding the even pixels to the odd pixels;
• and
• forming an even field by adding the odd pixels to the even pixels,
• wherein the odd field and even field comprise an interlaced scan image signal.
