Abstract
An output video signal is derived from an input video signal generated by an image sensor in response to an image formed on only part of the image sensor. The output video signal is derived in response to only the portion of the input video signal generated by the part of the image sensor on which the image is formed. The input video signal additionally includes a portion generated by the part of the image sensor on which the image is not formed. An image signal generating apparatus is provided in which the image sensor is mounted, and which includes a detachably-attached image-forming device. When attached to the image signal generating apparatus, the image-forming device forms the image on the part of the image sensor. A frame of the input video signal is received from the image sensor. The frame of the input video signal has a structure and includes an image portion generated by the part of the image sensor on which the image is formed, and an external portion generated by the part of the image sensor on which the image is not formed. The image portion of the frame of the input video signal is identified, and the identified image portion is extracted from the frame of the input video signal to provide the image portion of a frame of the output signal which has a frame structure substantially similar to the frame structure of the input video signal.
