Abstract
A variable focal length lens device includes an image-detection-condition setting unit configured to set image detection conditions. The image-detection-condition setting unit is configured to set, as image detection conditions, a combined mode of repeating an image detection loop including at least one multi-plane-image-detecting operation and at least one single-plane-image-detecting operation. In the multi-plane-image-detecting operation, a plurality of values of the focal length, at each of which the image detection is performed, are set in one cycle in which the focal length of the variable focal length lens is varied. In the single-plane-image-detecting operation, a single value of the focal length, at which the image detection is performed, is set in one cycle in which the focal length of the variable focal length lens is varied.
