Abstract: A cellular phone is capable of telephone-calling with an external device, and includes an antenna by which to communicate with the external device; a lens; an image sensor that outputs an image signal; a display; a loudspeaker; and a processer. The processor controls the display to display an announcement of an incoming call from the external device after receiving a calling signal via the antenna, and in a case that the calling signal is received during operation of the image sensor in a moving image mode, the processor permits communication between the cellular phone and the external device via the antenna and using the loudspeaker and a microphone of the cellular phone after the announcement of the incoming call is displayed by the display and after the processor receives an instruction from an input device of the cellular phone to allow starting of the telephone-calling with the external device.

Abstract: A sub-mirror which deflects a focal point detection light flux passing through an area off the optical axis of a photographing optical system toward the optical axis and a second deflection member that deflects the focal point detection light flux deflected by the sub-mirror to allow it to advance roughly parallel to the photographic optical axis are provided. A pair of light fluxes achieved by deflecting the focal point detection light flux twice are guided to an image sensor to form a pair of subject images on the image sensor. The focal adjustment state is detected based upon the extent to which the pair of subject images are offset.

Abstract: A focal point detection apparatus that includes a sub-mirror constituted of a concave mirror and performs focal point detection in the phase difference detection method is capable of implementing a focal point detection over a wide range. A light flux for focal point detection having passed through a semi-transmissive reflecting member and a reflecting member constituted of the concave mirror described above enters a focal point detection optical system. A correction optical system provided between the semi-transmissive reflecting member and the reflecting member constituted of the concave mirror corrects an offset of the direction along which the light flux for focal point detection advances caused by the reflecting member constituted of the concave mirror, in conformance to the image height at the focal point detection position. By utilizing this correction optical system, it becomes possible to reduce the size of the focal point detection apparatus while assuring a large focal point detection area.

Abstract: A focus detection device for precisely mounting a deflection member in a module body with high reliability. A module body retains a focus detection optical system. A portion of a hollow portion, through which a focus detection light beam passes, is formed by an aperture in the exterior of the module body. A deflecting member, which deflects the optical path of the focus detection light beam, is located in the aperture. A biasing member bias the deflecting member and restrains the deflecting member in a fixed location on the module body. A lens aggregate which has multiple lenses formed into a single body on the same substrate is forced against a support member in the module body to touch at contact areas. The contact areas on either the lens aggregate or the support member includes first, second and third protuberances.
