Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents experimental results on a method to improve the sampling rate in Optical Ccameras. In OCC using general-purpose image sensors, aamera Communication (OCC) by employing multiple major challenge is that the frame rate limits the maximum communication speed. To address this, a method has been proposed that exploits the integration sampling property occurring when an image sensor receives an optical signal. By processing signals from multiple cameras with clock offsets, the method achieves an effectively high frame rate. To verify the feasibility of the proposed method, we conducted experiments using a four-camera image sensor array with clock synchronization and demonstrated the effectiveness of sampling rate enhancement.
