An image pickup apparatus includes an image pickup element that includes a plurality of image pickup pixels and a plurality of focus detecting pixels, a detector configured to detect a phase difference between two images of the object on a secondary imaging plane, and a controller configured to provide focusing based on a defocus amount obtained from a detection result of the detector for a first focus detecting point, and set a correcting value used to correct a defocus amount obtained from a next detection result of the detector so that a difference can reduce between the defocus amount obtained from the detection result of the detector for the first focus detecting point and a defocus amount obtained from the focus detecting pixels for the first focus detecting point of a captured image of the object that has been captured.

A viewfinder display apparatus which can realize superimpose having good visibility without giving uncomfortable feeling to a photographer is disclosed. The viewfinder display apparatus includes an eyepiece lens unit, an a member on which illumination unit which irradiates illumination light, and a plurality of region display sections arranged in a viewfinder optical path respectively to correspond to the focus detection regions. Each of the region display sections includes an outer frame which partially transmits light from an object to display edges of the focus detection regions in the viewfinder field and reflecting region in which reflecting surface which reflects illumination light from the illumination unit to guide the reflected light to the eyepiece lens unit are formed.

A focus detecting device includes a focus detecting sensor having a glass plate affixed to a surface thereof, and a holding member which holds the focus detecting sensor. The holding member is provided with a first abutting surface on which the glass plate of the focus detecting sensor abuts, a second abutting surface on which a side surface of the focus detecting sensor abuts, and a groove, disposed between the first and second abutting surfaces, in which an adhesive for fixing the focus detecting sensor flows.

A network system is constructed by: a first LAN system having first terminal equipment; a second LAN system having second terminal equipment; an intermediate network to connect the first and second LAN systems; first communication equipment to transfer a packet between the first LAN system and the intermediate network; and second communication equipment to transfer a packet between the second LAN system and the intermediate network. To transfer the packet from the first terminal equipment to the second terminal equipment, the first communication equipment converts an address showing a transmission destination of the packet transmitted from the first terminal equipment from an address defined on the first LAN system to an address defined on the intermediate network and transfers the converted address from the first LAN system to the intermediate network. The second communication equipment converts an address showing the transmission destination of the packet on the intermediate network from the address defined on the intermediate network to an address defined on the second LAN system and transfers the converted address from the intermediate network to the second LAN system.

Network system including a plurality of lan systems and an intermediate network having independent address schemes

A still picture recording digital camera including a light quantity limiter for interrupting incident light to the camera; an image pickup unit including a pixel for converting the incident light to an electric pixel signal and outputting the pixel signal as a digital image signal; a signal processor for generating a digital image signal having a predetermined format; a recording unit for recording the digital image signal output from the image pickup unit or the signal processor; the light quantity limiter limiting the incident light quantity to a predetermined quantity and then interrupting the incident light; the image pickup unit outputting a dynamic picture digital image signal when the light quantity limiter is limiting the incident light quantity, and outputting a still picture image signal after the light quantity limiter has interrupted the incident light; and the signal processor performing different signal processing operations when the signal processor has received a digital image signal for a dynamic picture and a digital image signal for a still picture.

A second camera system is different from a first camera system in size of film to be used. While the first camera system is composed of a first camera body having a first camera bayonet mount and using a film of a first size and a first interchangeable lens having a first lens bayonet mount which is connectable to the first camera bayonet mount of the first camera body, the second camera system is composed of a second camera body having a second camera bayonet mount of which a configuration angle of a bayonet claw is different from that of the first camera bayonet mount and using a film of a second size which is smaller than the first size and a second interchangeable lens having a second lens bayonet mount which is connectable to the second camera bayonet mount and of which a configuration angle of a bayonet claw is different from that of the first lens bayonet mount, wherein the configuration angle of the bayonet claw of the second camera bayonet mount is set such that the second camera bayonet mount is connectable to both the first lens bayonet mount and the second lens bayonet mount, and the configuration angle of the bayonet claw of the second lens bayonet mount is set such that the second lens bayonet mount is connectable only to the second camera bayonet mount.

A magnetic disk apparatus has a disk assembly including a single servo disk and a plurality of data disks, a servo-head supporting structure for supporting a servo head and data-head supporting structures for supporting data heads. These heads are so disposed as to cooperate with respective disks. The servo-head and data-head supporting structures are driven by an actuator to move the servo head and the data heads to the required positions on the corresponding disks. The servo-head supporting structure and each of the data-head supporting structures have different proper oscillations to prevent the occurrence of a resonance during a seek operation.
