Abstract:
A CCD camera system capable of a multi-media response, comprising:a lens part for focusing optical signals of an object; a prism means for splitting the focused optical signals of said lens part into a first beam and a second beam; first and second CCDs for respectively converting the first and second beams into electrical signals, and having mutually different color filter arrays consisting of a complementary color stripe pattern and an effective number of pixels corresponding to an international standard; first and second sampling/holding means for carrying out sampling and holding functions to remove unnecessary signals such as noises from the output video signals of said first and second CCDs and outputting analog video signals; first and second analog-digital converting means for converting the analog video signals output by said first and second sampling/holding means into respective digital signals for carrying out digital signal processing; and a CCD video signal processing means for directly receiving the digital signals output by said first and second analog-digital converting means and calculating a sum of and a difference between the digital signal output by said first analog-digital converting means and the digital signal output by said second analog-digital converting means so as to generate brightness signals and color signals, wherein said CCD video signal processing means common since a first arithmetic means for adding the respective digital signals output by said first and second analog-digital converting means and outputting a corresponding signal; a second arithmetic means for subtracting the respective digital signals output by said first and second analog-digital converting means and outputting a corresponding signal: a brightness signal generating means for receiving the signal output by said first arithmetic means to generate a brightness signal; and a color signal generating means for receiving the signals output by said first and second arithmetic means to generate color signals by utilizing an internal color difference signal matrix.
