Abstract
A section deriving unit ( ) derives a section to which a digital input value DIN belongs and outputs a section number IVN, and a computation parameter output unit ( ) outputs a computation Parameter CPA corresponding to IVN. A computation unit ( ) performs a given computation based on DIN and CPA and outputs the result of the computation as a digital output value DOUT. Any DIN-DOUT conversion characteristic that the user requires can be obtained by setting a delimiter information storage unit ( ) and a computation parameter storage unit ( ) as appropriate. The computation unit ( ) could, for example, perform a calculation DOUT=a X +a X + . . . a X+a , based on computation parameters a to a . This look-up table device can be used for gamma compensation or depth cueing conversions.
