Disclosed is an imaging apparatus capable of enlarging a portion of an image captured by an imaging device of a fisheye camera and displaying the enlarged image on a display screen with little distortion. The imaging apparatus enlarges a section, which is a portion of an image captured by a fisheye camera, and displays the section on a display screen such that the enlargement ratios of points in the section are different from each other. An image processing method uses a change function that changes the enlargement ratio of a field angle depending on the place is used, and converts a portion of the captured image into a central projection image to generate a display image. The use of the change function makes it possible to generate a display image having high visibility.

Imaging apparatus

In order to provide a paper-feeding stepping motor driving method which inhibits the torque of a paper-feeding stepping motor of a line-type thermal printer, which is driven in response to the divisional energization of heating elements, from excessively increasing during dynamic division printing, and which achieves noise reduction and energy conservation, while a driving signal to be applied to the paper-feeding stepping motor is active, an active pulse is subdivided.
