Abstract
In an image processing apparatus, an input image is synthesized with a stored image supplied from a storage unit and having been shifted so that the positions of the pixels in the image areas of the input image and of the stored image, associated with a telop, will coincide. The level distribution of the pixel values of the input image is maintained in the telop.
Claims11
A method of processing an input digital image signal, said method comprising the steps of:
- storing a digital image signal;
- extracting a signal representing a specific area from the digital image signal stored;
- detecting a motion of the specific area based on the input digital image signal and the extracted signal representing a specific area;
- synthesizing the input digital image signal and the digital image signal stored in said storing means so as to align a position of the extracted specific area and a position of a corresponding area represented by the input digital image signal;
- and
- updating the digital image signal stored with a signal obtained in the synthesizing step.
