Embodiment Construction
[0124] Figure 1 is a block diagram of a simplified image acquisition, compression and wireless transmission system of the wireless endoscopy capsule system. The Bayer color format image data output by the image sensor in the wireless endoscopy capsule is directly compressed, and then sent to the channel coding unit, after channel coding, output to the wireless transceiver, and sent to the body in the form of radio waves. The capsule can also receive control command data from the outside through the wireless transceiver, and then send it to the channel decoding unit. The decoded data is output to the control unit, and the control unit controls the next action of the circuit in the capsule according to the received control command.
[0125] Figure 2 is the BAYER format color image array output by the image sensor. The G component data of the image is a diamond shape, and the data volume accounts for 1 / 2 of the entire Bayer image data volume, and the R and B components are rectangula...
