To preferentially provide an image with an excellent observation by estimating an observation condition with a simple method.SOLUTION: An image compression section 13 compresses image data 54 as compression image data 55. A storage part 15 stores an observation ID 52 used for identification of the compression image data 55, the compression image data 55, and a compressibility ratio 56 of a ground so as to be associated with each other. A command acquisition part 14 acquires transmission image designation information 57 containing the plurality of observations ID 52 corresponded to each of the plurality of compression image data 55 transmitted to an earth station 10. A transmission order determination part 20 determines a transmission order 58 for transmitting the plurality of compression image data 55 to the earth station 10 on the basis of the compressibility ratio 56 corresponded to each of the plurality of observations ID 52 contained in the transmission image designation information 57. A transmission part 17 transmits the plurality of compression image data 55 to the earth station 10 in accordance with the transmission order 58.SELECTED DRAWING: Figure 1
【課題】簡便な方法で観測条件を推定し、観測条件の良い画像を優先的に提供することを目的とする。【解決手段】画像圧縮部13が、画像データ54を圧縮画像データ55として圧縮する。記憶部15が、圧縮画像データ55の識別に用いられる観測ID52と圧縮画像データ55と地表の圧縮率56とを対応付けて記憶する。コマンド取得部14は、地上局10に伝送する複数の圧縮画像データ55の各々に対応する複数の観測ID52を含む伝送画像指定情報57を取得する。伝送順序決定部20は、伝送画像指定情報57に含まれる複数の観測ID52の各々に対応する圧縮率56に基づいて、複数の圧縮画像データ55について地上局10へ伝送する伝送順序58を決定する。伝送部17は、伝送順序58に従って、複数の圧縮画像データ55を地上局10に伝送する。【選択図】図1
