ABSTRACT:
When a logarithmic spiral function curve exists at a position specified by variables, a filter coefficient corresponding to the position is obtained through calculation using Gaussian function stored in a Gaussian function memory, and the filter coefficient is stored in a filter coefficient memory in association with the position specified by the variables. Retinex processing is executed on original image data using the filter coefficients stored in the filter coefficient memory.
