Single-pixel imaging (SPI) enables image acquisition using a single detector and a set of spatial modulation patterns. However, a large number of measurements are generally required for accurate image reconstruction, resulting in long acquisition times. In this study, we propose adaptive binary random patterns whose reflectance ratios are optimized according to the signal intensity distribution of the target image. Numerical simulations were performed using magnetic field distribution images. The results demonstrated that the proposed adaptive patterns achieved reconstruction quality comparable to that of conventional random patterns while reducing the required number of measurements from approximately 80% to 50%. The proposed method is expected to improve the measurement efficiency of SPI-based imaging systems.
