Abstract: An image processing system receives an input gradient number m, input image data I(x,y) whose input gradient number is m, and an output gradient number n and calculates output image data O(x,y) having an output gradient number of n on the basis of the following formula (1). O(x,y)=int[?+d(xd,yd)/(gmax+1)] ??(1) When ? is an integer, the output image data O(x,y) is calculated on the basis of a formula obtained by substituting the calculated ?? for ? in the above formula (1), whereas when ? is not an integer, the output image data O(x,y) is calculated on the basis of the above formula (1).

Abstract: An information processing apparatus for allowing a non-networked unit to function as one unit disposed in a network environment. A network adapter obtains detailed profile data on the Internet according to simple profile data obtained from the outside. The network adapter enters service data generated according to these pieces of profile data, in a service discovery server. Then, the network adapter reads the service data from the service discovery server and refers to it to execute an operation for implementing service indicated by the service data by using an interface with a non-networked unit. With this, a function which cannot be implemented if the non-networked unit is not connected to a network is given to the non-networked unit through the network adapter.
