Abstract:
1. An image processing apparatus comprising: a reception unit that receives first, second, and third encoded image data; a decoding unit that decodes the first encoded image data to generate a main frame; a sub frame generating unit that extracts a low frequency component from the second encoded image data, extracts a low frequency component from the third encoded image data, generates a first sub frame from the low frequency component of the second encoded image data, and generates a second sub frame from the low frequency component extracted from the third encoded image data; and an image signal generating unit that combines the main frame generated from the first encoded image data, the first sub frame generated from the low frequency component of the second encoded image data, and the second sub frame generated from the low frequency component of the third encoded image data, and generates an image signal including the main frame generated from the first encoded image data, the first sub frame generated from the low frequency component of the second encoded image data, and the second sub frame generated from the low frequency component of the third encoded image data; and wherein if a switching key is rotated to left side, (a) the decoding unit decodes the second encoded image data to generate the main frame, (b) the sub frame generating unit extracts the low frequency component from the third encoded image data, extracts a low frequency component from the first encoded image data, generates the first sub frame from the low frequency component extracted from the third encoded image data, and generates the second sub frame from the low frequency component extracted from the first encoded image data, and (c) the image signal generating unit combines the main frame generated from the second encoded image data, the first sub frame generated from the low frequency component of the third encoded image data, and the second sub frame generated from the low frequency component of the first encoded image data, and generates an image signal including the main frame generated from the second encoded image data, the first sub frame generated from the low frequency component of the third encoded image data, and the second sub frame generated from the low frequency component of the first encoded image data, and wherein if the switching key is rotated to right side, (a) the decoding unit decodes the third encoded image data to generate the main frame, (b) the sub frame generating unit extracts the low frequency component from the first encoded image data, extracts the low frequency component from the second encoded image data, generates the first sub frame from the low frequency component extracted from the first encoded image data, and generates the second sub frame from the low frequency component extracted from the second encoded image data, and (c) the image signal generating unit combines the main frame generated from the third encoded image data, the first sub frame generated from the low frequency component of the first encoded image data, and the second sub frame generated from the low frequency component of the second encoded image data, and generates an image signal including the main frame generated from the third encoded image data, the first sub frame generated from the low frequency component of the first encoded image data, and the second sub frame generated from the low frequency component of the second encoded image data.
