Summary:•Reconstruction quality of images was evaluated using compressed ultrafast photography (CUP) system.•Reconstruction quality depends on defect rates.•A multi-directional high-speed imaging system based on CUP system was demonstrated.•The system reconstructed the shape of two images from one swept image. We evaluated the reconstruction quality from a conventional compressed ultrafast photography (CUP) system and demonstrated a multi-directional high-speed imaging system based on the CUP system. We evaluated the defect rate as a function of the reconstruction quality. The results showed that the dependence of the defect rate on the reconstruction quality is similar to that from numerical experiments used to evaluate the mean square error (MSE). The results indicate that the shapes of two images could be reconstructed from one swept image.
