Therefore, preliminary sampling is performed to prepare for actual shooting.

Step: # 610 # 611 # 612 # 613 Wide W: Preliminary sampling Preliminary sampling --- Normal N: Setting position Setting position Setting position Setting position TeleT: Predictable ------ Predictable −−−−−

By using the method disclosed in Japanese Patent No. 50743, it is possible to process and display as a prediction result without actually performing zooming. When the main subject is included when estimating the composition and only the size is desired to be viewed, the preliminary sampling used for display need not be performed in order to improve the quick shooting performance.
