An image sensing apparatus invention has an image sensing device for sensing a subject image from a range which is wider than a photographic range, a processor for calculating position information of a subject with respect to the photographic range based on an output from the image sensing device, a discriminator for determining whether photographing is appropriately performed or not, based on information calculated by the processor, and a notifier for notifying a result of determination by the discriminator before photographing. In this structure, appropriate photographing can be performed by referring to the notifying contents of the notifier.
