1. An image capturing apparatus comprising: an image capturing section; a moving image capturing control section for causing the image capturing section to capture a moving image including a plurality of frame images; a still image capturing instruction reception section for receiving an instruction to capture a still image when the image capturing section continuously captures the plurality of frame images; a still image capturing control section for causing the image capturing section to capture the still image at a timing after the capturing instruction reception section receives the instruction to capture the still image and before the image capturing section captures a frame image following the last frame image captured when the still image capturing instruction reception section receives the instruction to capture the still image; a still image capturing timing recording section for recording a still image capturing timing at which the image capturing section captures the still image; a frame image before/after image capturing extracting section for extracting the frame image captured before and the frame image captured after the still image capturing timing recorded by the still image capturing timing recording section from the plurality of frame images captured by the image capturing section: a frame image generating section for creating a frame image at the timing at which the image capturing section captures the still image based on the frame image captured before and the frame image captured after the still image capturing timing extracted by the frame image before/after image-capturing extracting section; an image memory for storing the moving image and the still image captured by the image capturing section and the frame image generated by the frame image generating section; and an image storage control section for preferentially deleting the frame image stored in the image memory, which is created by the frame image generating section than the moving image and the still image stored in the image memory, which are captured by the image capturing section when the amount of space for storing a moving image or a still image newly captured by the image capturing section runs short in the image memory, and for causing the image memory to store the moving image or the still image newly captured by the image capturing section.
