Abstract
A camera platform apparatus () sequentially moves an image capturing direction of an image capturing apparatus () with respect to an object to be inspected. The image capturing apparatus () acquires a captured image of each section of the object by performing image capturing in each image capturing direction. A computational operation apparatus () records a focus control position for each section of the object whose image is captured by the image capturing apparatus () in each image capturing direction. In a case where AF is not successful when image capturing is performed on a section whose image is not yet captured, the computational operation apparatus () sets an allowable range of the focus control position for the section for which the AF is not successful based on the recorded focus control positions, and the computational operation apparatus () controls the image capturing apparatus () to perform focus BLK image capturing within the set range.
