The spacial and size distributions of the small solar system bodies are important to investigate the processes of the solar system formation. They orbit near the Earth, so that they appear to move in the celestial sphere. Usually, more than three images are used to detect moving objects, but we detect them with two images because we can also make use of the data by other observations than surveys for small bodies. And we have originally developed the automatic detection program to analyze the data rapidly. This time, we have analyzed the r'-band data by Suprime-Cam on the Subaru telescope over the 1.9 square-degree field. The limiting magnitude was 24.4 mag. We detected 287 moving objects, and the slope of the cumulative size distribution obtained by them agreed with past researches.
