Abstract: PROBLEM TO BE SOLVED: To shorten the time for an information area acquisition in individual area acquiring processes and speed up the retrieval of an information area, and to efficiently use a main storage by acquiring the entire information area of individual information area not in K queue structure, but in an array structure. SOLUTION: A process part requests an area acquiring process part 2 to acquire an area for information storage needed for a new certain process each time the process is generated. The area acquiring process part 2 acquires an information area 30 individually on the main storage 3 and links it with information areas 31, which are already structured in array structure, in queue structure. The area acquiring process part 2 calculates an optimum value from the number of the information areas 30, already acquired, which is stored in an acquisition number storage area 20 when the information processor stops. For operation, the information areas 31 which are acquired in the array structure are used when the processor is restarted.  If an information area acquisition request exceeding the size of the information areas 31 in this array structure is made, an information area 30 is newly acquired and linked with the existent information areas 31 in the array structure in queue structure.

On the other hand, a Peano scan processing means 32 scans all the grid points of the discrete coordinate system along a three-dimensional Peano curve with the origin of the discrete coordinate system as a starting point to an ending point on the coordinate axes expressing the luminance components and outputs the information of distance from the starting point to the ending point at the time when the coordinate values of grid points are coincident with the coordinate axes stored in the color coordinate information storage means 31. A luminance value converting means 4 performs arithmetic for multiplying the distance information for a constant and outputs the result to a luminance value output means 5.
