Abstract: A variable focal length lens, as well as a focal length adjusting device and an imaging device using the same. A variable focal length lens has a lens, a positive electrode, and a negative electrode.

When a voltage is applied between the positive electrode and the negative electrode, the second layer and first layer are deformed to be pulled to the positive electrode, and thereby the curvature of the variable focal length lens is varied to vary the focal length.

Abstract: The present invention provides a portable image capturing apparatus having also a navigation function while preventing increase in the size and manufacturing cost of the apparatus. As a part for displaying a guide screen of a navigation system, a rear LCD capable of displaying a high-definition image of an image capturing apparatus which can be carried by a user is used. In other words, a part in which a display of a car navigation system is formed can be separated from the car navigation system and used as a digital camera. Therefore, only by connecting the image capturing apparatus to a car navigation system body in a data transmittable/receivable manner without providing most of functions necessary for car navigation for the image capturing apparatus, the car navigation system is formed.

Abstract: The video display apparatus of the present invention detects a vertical picture size steadily and displays a picture from a video signal accompanied by a closed caption, so that the closed caption does not fall out of the display screen. A closed caption decoder extracts a start line code which determines a position from which a horizontal scan starts along a vertical axis of an active picture area of the video signal and an end line code which determines a position at which the horizontal scan terminates. Based on the start line code and the end line code, a vertical picture size is calculated, and position in which the closed caption information is to be displayed is controlled, according to the vertical picture size.
