Frame generation apparatus, frame generation method, image synthesis apparatus, image synthesis method, signal generation apparatus, signal generation method, and image transmission system

A frame generation method comprising:

• dividing a video signal into high-order bits and low-order bits for each pixel element;
• generating a first frame including the high-order bits and a second frame including the low-order bits;
• and
• causing an operation of a transmission section of transmitting the second frame to a receiver to stop in a case where information regarding the receiver is prescribed information.

An image synthesis apparatus comprising:

• a pixel extraction section configured to extract high-order bits and low-order bits from, respectively, a first frame and a second frame including, respectively, the high-order bits and the low-order bits that are obtained by a video signal to be received by a receiver being divided for each pixel element in a case where the first frame and the second frame are received from a transmitter;
• an image synthesis section configured to synthesize the high-order bits and the low-order bits to restore the video signal;
• and
• a reception operation control section configured to make control so as to stop an operation of a reception section of receiving the second frame from the transmitter in a case where information regarding the receiver is prescribed information.
