Abstract

PURPOSE:To realize uses for correcting and expanding a pitcure of a sea area on a ground-surface process by a satellite with no fruitless process and with a processing time shortened, by providing a decision device and arithmetic unit for interpolation of data on sampled values. CONSTITUTION:This processor consists of storage register groups 5a to 5d for coordinate information on sampling points, registers 6a to 6d stored with data at each coordinate, subtracters 9 and 10, multiplier 11, address 12 and 13, decision device 1, weight-function arithmetic unit 3, accumulator 4, interlocking selectors 2a and 2b, etc. By device 1, it is discriminated whether at least three of contents zi-1, zi, ...zi+2 of registers 6a to 6d are equal or not; when three values are equal, z of the value is set to register and selector 2b is so driven so that it will be connected to resister 6 which has one value of the rest unequal to z . When values of register 6a to 6d are all equal, on the other hand, the value z is set to register 8 and then, selector 2b is connected to any register 6.
