  • Patent number: 7995138
    Abstract: Maximum and minimum aperture sizes are regulated with regard to a diaphragm in order to secure predetermined optical capability in an optical unit which includes a taking lens and the diaphragm. In normal taking, the diaphragm is used within a normal taking range from the maximum to the minimum aperture sizes. In the present invention, an aperture size which is larger than the maximum size and a size which is smaller than the minimum size (extra aperture size or extra small size) are respectively set at outside the range that secures the capability. The aperture sizes of the diaphragm at outside the specified range are used at least for one of the following: automatic exposure (AE) adjustment, auto focus (AF) adjustment, electronic zoom, displaying a moving image, taking for recording the moving image, and taking under a low resolution by thinning out pixels.

  • Patent number: 7675478
    Abstract: The camera reads identification information of the user, which is contained in an identification card, through a card reading part. The camera connects automatically to a server designated in accordance with the read identification information through a communication interface. Then, the camera transmits and stores the data of recorded images to the designated server. The camera retrieves the image data stored in the server, and reproduces and displays the image on an image display at the back of the camera. A plurality of cameras in which the same user's identification information is set can be controlled altogether in the image-recording and reproduction by one camera. One camera in which the identification information of a plurality of user's is set can distribute the recorded image data to the servers of the users simultaneously.

  • Patent number: 7667768
    Abstract: An image-capturing apparatus is capable of capturing a three-dimensional image and a high quality panoramic image as the need arises, and is portable if it is used as a single lens camera that captures a normal two-dimensional image. A second image-capturing unit having an image-capturing optical system is detachably connected to a first image-capturing unit, which is capable of functioning as an image-capturing apparatus by itself, through joints and a connector. The second image-capturing unit can extensively connect to other units, which have the similar connecting structure. Information is transmitted between the units through a slot for an external storage device. There is provided a means for adjusting the positions of images captured by the second and subsequent image-capturing units with respect to an image captured by the first image-capturing unit.

  • Patent number: 7471888
    Abstract: A cellular telephone handset has a built-in image pickup device. A lid shaped reception unit is slidable on a transmission unit or main body between closed and open positions, lies on a first surface of the main body when in the closed position, and uncovers at least part of the first surface when in the open position. An image sensor to pick up an image is contained in the main body. A first lens element receives object light incident thereon. Plural second lens elements in the main body have an optical axis extending in a sliding direction of the lid shaped reception unit, for introducing the object light to the image sensor. A path bending prism introduces the object light to the second lens elements by changing an optical path of the object light from the first lens element. An optical path length of the second lens elements is changeable.
