Outline of Final Research Achievements

In this research project, we have developed a method for realizing random access to optical imaging parameters that allows the selection of arbitrary focal lengths and viewing directions for each frame of the image sensor. We have also developed a method to realize parallel random-access imaging, in which multiple images with different focal lengths and viewing directions are captured simultaneously. As an application of these techniques, we developed a 100-volume/s high-speed light-sheet microscope and demonstrated its effectiveness in the measurement of swimming cells. We also developed a visual tracking method based on random access in the direction of gaze, and demonstrated its usefulness through experiments.

Academic Significance and Societal Importance of the Research Achievements

本研究を実施したことにより，カメラの視線方向や焦点距離をフレーム毎に自由に選択できる新しい手法を開発，実証することができた．これによって工場における画像検査や自動走行における画像センサが，動的な環境に対してより適応的に撮影条件を選択できるようになり，より多様な条件でロバストに稼働できる画像システムの実現に寄与する．
