WIRELESS IMAGE TRANSFER SYSTEM AND WIRELESS IMAGE TRANSFER METHOD

摘要

A wireless image transfer system includes an image quality judgement unit configured to judge reception states of a first image transmitted in a first frequency band by a first image wireless block and a second image transmitted in a second frequency band by a second image wireless block and image qualities of the received images; and a second control unit configured to sort the reception states into a good state, a bad state, and an intermediate state, select a first image signal in the good state, steadily operate the second image wireless block and periodically operate the first image wireless block in the bad state, and select an image with a better quality from the first image signal and a second image signal and output the selected image in the intermediate state.

主权项

1. A wireless image transfer system comprising a transmitter and a receiver, the transmitter comprising:
a first image wireless block configured to wirelessly transfer an image signal in a first frequency band; a second image wireless block configured to wirelessly transfer the image signal in a second frequency band different from the first frequency band; and a first control unit configured to control the first and second image wireless blocks, and the receiver comprising: a third image wireless block configured to receive a signal transmitted by the first image wireless block to obtain a first image signal; a fourth image wireless block configured to receive a signal transmitted by the second image wireless block to obtain a second image signal; a reception state acquisition unit configured to acquire information of a reception state in the third image wireless block; an image quality judgement unit configured to judge image qualities of images based on the first and second image signals obtained by the third and fourth image wireless blocks, respectively; and a second control unit configured to sort the reception state in the third image wireless block into a good state, a bad state, and an intermediate state based on the information of the reception state, select the first image signal from the third image wireless block in the good state, steadily operate the second image wireless block and periodically operate the first image wireless block in the bad state, and select an image with a better quality from the first and second image signals and output the selected image in the intermediate state.
