Abstract: An image sensor of an image capture device may capture an image. The captured image may be stored in a buffer of two or more previously-captured images. An oldest image of the two or more previously-captured images may be removed from the buffer. An aggregate image of the images in the buffer may be updated. This updating may involve subtracting a representation of the oldest image from the aggregate image, and adding a representation of the captured image to the aggregate image. A viewfinder of the image capture device may display a representation of the aggregate image.
Abstract: The present disclosure provides techniques for enabling a metadata storage subsystem. A directory of available metadata is created, and the metadata is stored in various system data stores. The metadata is retrieved as requested by a host device, and the metadata is transferred to the host device. Additionally, the metadata is executed.
Abstract: An anti-shake apparatus of a photographing-apparatus comprises a movable-unit and a fixed-unit. The movable-unit has an imaging-device and a position-detecting magnet. The movable-unit can be moved in a first-direction and a second-direction. The fixed-unit has a hall-element unit. The first-direction is perpendicular to an optical-axis of a camera-lens of the photographing-apparatus. The second-direction is perpendicular to the optical-axis and the first-direction. The position-detecting magnet is used for detecting a first location in the first-direction of the movable-unit and a second location in the second-direction of the movable-unit, and has a front-surface which faces the hall-element unit. The hall-element unit has hall-elements which are used for detecting the first location, and has hall-elements which are used for detecting the second location, and faces the position-detecting magnet.

Abstract: A digital camera includes a mirror box having a lens mount to which a photographing lens is mounted; an image pick-up device having an imaging surface for capturing an object image which is focused on the imaging surface through the photographing lens; and a frame positioned inside the digital camera body, the mirror box and the image pick-up device being mounted to the frame. The mirror box is mounted to a surface of the frame. The image pick-up device is mounted to the surface of the frame via at least one support member positioned between the mirror box and the image pick-up device. A ratio of a distance from the lens mount to the frame and a length of the support member is substantially equal to a ratio of a linear expansion coefficient of the support member and a linear expansion coefficient of the mirror box.
Abstract: A monitoring camera with a far infrared capability has a cylindrical body (10), a lens hood (20), a luminous body (30) with multiple far infrared light emitting diodes (LEDs) and a lens cover (40). The lens hood (20) is a hollow cylinder and is divided into an inner segment and an enlarged outer segment (23) communicating with the inner segment. The enlarged outer portion (23) provides an enlarged compartment to hold a larger luminous body (30), which can hold more far infrared LEDs so the monitoring camera can see object at greater visual distances. Additionally, the field of vision the monitoring camera is also greater.
Abstract: A solid-state image sensor for a solid-state image pickup apparatus includes photosensitive cells each having a photosensitive area divided into a main region and a subregion. The subregion is extended to include the position of a virtual pixel. A light-screening layer is formed with optical openings corresponding to the main and subregions, so that light is incident not only to the main region or actual pixel but also to the subregion at the position of the virtual pixel. Spatial information is therefore available even at the position of the virtual pixel in the form of a signal charge.
Abstract: An imaging array having one or more columns of pixels is disclosed. Each pixel includes a photodiode including first and second terminals, a local reset circuit for connecting the first terminal to a column reset line; and a buffer circuit for selectively connecting the first terminal to a column bit line in response to a word select signal. Each column also includes a column reset circuit having an operational amplifier and a low-pass filter. The operational amplifier has a first input connected to the column bit line for that column and a second input connected to a reset signal generator that generates a reset signal during a reset cycle. The output of the operational amplifier is connected to the column reset line during the reset cycle. In one embodiment, the gain of the operational amplifier and the passband of the low-pass filter are varied during the reset cycle.
