IMAGE SIGNAL PROCESSING MODE SWITCHING APPARATUS AND IMAGE SIGNAL PROCESSING MODE SWITCHING METHOD

摘要

According to one embodiment, a decoder outputs a decoded image signal by decoding an encoded image signal in accordance with additional data. A signal processor processes the decoded image signal in a 2D image signal processing mode or a 3D image signal processing mode. A first detector detects whether a specific picture frame of the encoded image signal has been decoded. A second detector analyzes the additional data, detecting whether the encoded image signal pertains to 2D or 3D. When the first detector detects that the specific picture frame has been decoded, the second detector outputs the result of detection to a signal processing mode switch provided in the signal processor.
