Patent ID: 8908756

Claim:
An image transmission apparatus for wirelessly communicating with an external apparatus, comprising: an image pick-up unit configured to output a pixel signal corresponding to an amount of incident light; a first image data compression unit configured to compress an image frame data, which corresponds to the pixel signal output from the image pick-up unit, by a lossy compression to output a compressed image frame data; a second image data compression unit configured to compress the image frame data by a lossy compression, which is at a lower compression rate than the lossy compression by the first image data compression unit, to output a compressed image frame data, or to output the image frame data that is uncompressed or compressed by a lossless compression; a transmission unit configured to wirelessly transmit the compressed image frame data, which has been compressed by the lossy compression and output by the first image data compression unit, as a first image data to the external apparatus through wireless communication, the transmission unit being configured to wirelessly transmit the compressed image frame data, which has been compressed by the lossy compression and output by the second image data compression unit, or the image frame data, which is uncompressed or compressed by the lossless compression and output by the second image data compression unit as a second image data; a manipulation unit configured to output a disconnection signal to disconnect a wireless communication by the transmission unit in response to an external manipulation; and a control unit configured to receive the disconnection signal from the manipulation unit and before instructing the transmission unit to disconnect the wireless communication in response to the disconnection signal, determining whether the transmission of the second image data by the transmission unit has been completed and instructing the transmission unit to complete the transmission of the second image data if the transmission of the second image data has not been completed and after completion of the transmission of the second image data, instructing the transmission unit to disconnect the wireless communication with the external apparatus.
