ABSTRACT:
In the teleconference and videophone system, a display apparatus is placed in front of the speaker, and thus a camera cannot be placed in front of the speaker. This causes distortions in the image shot by the camera. With the image signal processing apparatus of the present invention, a parameter detecting unit detects a distortion of a line in a vertical direction in a distortion detecting picture in which the distortion is detected. The image correcting unit corrects an image in a picture to be corrected which is inputted subsequent to the distortion detecting picture, so as to eliminate a horizontal shift of the image corresponding to the distortion of the line in the vertical direction detected by the parameter detecting unit.
