Title: Imaging apparatus
Inventor: IDE HIDEKAZU
IPC: G02B7/08
Filed: 2002-09-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide an imaging apparatus which can realize a focusing sensitivity with adequate operability in the case of a manual focusing operation.  <P>SOLUTION: The imaging apparatus is provided with a focusing ring such that manual focusing operation can be made. In rotating the focusing ring, the focal length changes but if a focus evaluation value is large like in a curve Cb indicating the relation between the respective focal lengths and the actual moving quantity of the focusing lens, and more particularly if the value exceeds Pmax, the actual moving quantity of the focusing lens is suppressed. The actual moving quantity of the focusing lens per unit displacement volume of the focusing ring is thereby decreased when the ring is moved closer to a focusing position and therefore the focusing can be eventually performed with high accuracy. Consequently, the adequate operability and the focusing sensitivity in the manual focusing operation can be realized.  <P>COPYRIGHT: (C)2004,JPO
