Summary:We propose a method for determining a code set based on the reflectance of the scene in the coded exposure photography technique using multiple color LEDs with same power. Coded exposure imaging affects image brightness, which affects motion deblurring performance. Thus, the performance of the motion deblurring depends on the duty cycle of the code. Previously, since the image was modulated with a single code, the duty cycle of the code considered only the overall brightness of the scene. The coded imaging with multiple color LEDs can consider the brightness of each color channel, allowing the code set to be further optimized based on the reflectance of each color in the scene. We demonstrated the effectiveness of our method by comparing it with conventional methods and confirmed that the average PSNR increases by 2.2dB.
