Abstract
In an imaging field changing apparatus capable of changing three or more imaging fields having different aspect ratios, a changing order can be set such that one of two imaging fields having largest rate of change in aspect ratios during imaging field changing is changed to the other of the two imaging fields. The imaging fields are exemplified as a standard size, a panorama size, and a high-vision size. Aspect ratio changing is performed such that the standard size is changed to the panorama size. A change in imaging field can be easily recognized. For example, when a change is to be made between the standard size and the panorama size, the upper and lower portions are cut or trimmed and the right and left portions are widened to emphasize wideness.
