An image generation system which generates an image including no temporal and spatial missing images, includes: a processor that executes a program; and a memory that stores the program executed by the processor. The processor calculates spectral correction parameters for transformation between a first image and a second image using the first image and the second image of different resolutions having captured the same area on the ground; calculates temporal change correction parameters for correction of temporal changes using two second images captured at different times; and generates a missing image of the first image from the second image captured at a time different from the first image using the spectral correction parameters and the temporal change correction parameters. t t TIME I------------------------------------------ ------------------ 1 SATELLITE IMAGE 1 A10(t) B11(t) L --------------------------------------------------------------------------- I -------------------------------------------------------- | SATELLITE IMAGE 2 AC(t- LOD A|(t) A|(t ) BB 2 (t) -B 20(t) NO TEMPORAL I - NO CHANGE SPECTRAL CHANGE TEMPORAL CLOUD (2) - ______ CHANGE (4) T d '2 d , dia d=2A|()Aft) dl=f,(A|(t) -A (t) ds =f2 (A 2(t)-A() (3) (5) F-------------------- --------- SATELLITE IMAGE 3 A1|(t A|(t) SIMULATE ------- B(t) B B f(t)= B|(t)+ d2+d, Af(t)=A10(t)+d3 + d B(ti)=B20(ti)+d L ----------------------------------------- SIMULATION IMAGE 0: NON-CLOUD AREA, 1: CLOUD AREA An~t)--> TIME SATELLITE IMAGE |
