Abstract
In the image capturing apparatus, the optical path difference producing member is disposed on the second optical path. Thereby, at the second imaging device, it is possible to suppress the amount of light on image pickup of an optical image which is focused at the front of an optical image made incident into the first imaging device (front focus) and on image pickup of an optical image which is focused at the rear thereof (rear focus) and also to secure the amount of light on image pickup by the first imaging device. Further, in the image capturing apparatus, based on a scanning velocity v of the stage and an interval d between the first imaging region and the second imaging region, a waiting time is set from image pickup at the first imaging region to image pickup at the second imaging region. As a result, light from the same position of the sample is made incident into the first imaging region and the second imaging region. Thus, it is possible to control a focus position at high accuracy.
