Patent ID: 8035701

Claim:
An image tuning system comprising: an image processing device; and a computer that is external to the image processing device, wherein the image processing device comprises: an image sensor (IS) receiving external image data; a parallel unit (PU) receiving and outputting parallel image data from the computer; a first multiplexer (MP) receiving the parallel image data and an output of the IS; an image signal processor (ISP) receiving an output of the first MP; a serial unit (SU) receiving and outputting serial image data from the ISP; and a second MP receiving an output of the first MP, an output of the ISP, and an output of the SU, wherein during a first mode, the ISP receives and processes an output of the IS from the first MP to output a first processed image signal, the second MP outputs the first processed image signal, and the computer calculates a tuning parameter from the first processed image signal, wherein during a second mode, the second MP receives and outputs an output of the IS from the first MP to output an un-processed image signal, and the computer stores the un-processed image signal as a stored image signal, and wherein during a third mode, the computer outputs the stored image signal, the PU outputs the parallel image data based on the output stored image, the first MP outputs the parallel image data to the ISP, the ISP processes the parallel image data to output a second processed image signal to the SU, the SU outputs the second processed image signal as the serial image data to the second MP, the second MP outputs the serial image data, and the computer adjusts the tuning parameter using the serial image data.
