Abstract
The present invention provides a camera with a blur warning function which does not widely vary in feeling of use between film-loading and film-unloading. In this camera, a film loading sensing section senses whether a film is loaded or not, a focal length sensing section senses a focal length of a lens, and a camera shake sensing section senses a camera shake. In response to outputs of the film loading section, the focal length sensing section and the camera shake sensing section, a blur amount of an image formed on a film surface is computed by an image blur computing section. A blur warning section gives a warning of an image blur amount in response to an output of the image blur computing section. The information of the blur warning section is controlled by the image blur computing section in accordance with at least information of the film loading sensing section.
