Abstract:
A retention mechanism includes a fixed part including a magnet, and a movable part opposed to the fixed part. A plurality of rolling elements are provided between the fixed part and the movable part, and the movable part is movable in a plane direction. A magnetic material which forms, in combination with the magnet, a magnetic spring is provided on the movable part. The magnetic spring generates a magnetic attraction force which attracts the movable part to the fixed part. The magnetic material is extended along a direction in which magnetic poles of the magnet are arrayed.
Abstract:
A zoom lens includes in order from an object side to an image side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a negative refractive power. At the time of zooming, distances between the lens units change, and a distance between the first lens unit and the second lens unit at a telephoto end is shorter than a distance between the first lens unit and the second lens unit at a wide angle end, and an aperture stop is disposed on an image side of an image-side surface of the first lens unit, and on an object side of an image-side surface of the second lens unit, and the zoom lens satisfies the conditional expressions.
Abstract:
An image pickup apparatus including an image pickup device having a pixel section with a plurality of two-dimensionally arranged pixels and a frame memory which temporarily stores, in an analog manner, analog image data read out from the pixel section and first to third readout control sections which perform first readout control that reads out image data of all pixels obtained through one exposure from the pixel section and stores the image data in the frame memory and perform second readout control that nondestructively reads out a piece of image data of a smaller number of pixels than all the pixels from the image data of all the pixels stored in the frame memory a plurality of times such that the piece of image data each has different object region size.
Abstract:

Abstract:
The present invention is an image pickup apparatus including: an image processing section configured to be capable of outputting a cut-off image (cropped image) corresponding to an optical image formed on a specified area of an image pickup device; an image display device; a touch panel provided on the image display device; and a control section; wherein if the touch panel detects a drag operation during a live view display operation being performed on the image display device, the specified area is caused to relatively move with respect to the optical image according to a movement direction and movement distance of the drag operation.
Abstract:
A communication apparatus includes an operation information converting unit that converts a relative position change between a portable apparatus and a communication apparatus into operation information in order to establish wireless communication with the portable apparatus, a transceiving unit that receives the operation information from the portable apparatus, and a transmission control unit that causes the transceiving unit to establish communication for transmitting content data to the portable apparatus when the operation information received by the transceiving unit matches operation information which is set in advance.
Abstract:
An imaging apparatus generates one piece of image including a moving image and a still image which are continuously shot. The apparatus includes an imaging unit, a still image acquisition instruction unit, a moving image acquisition start instruction unit, a time measuring unit, and a moving image time determination unit. The imaging unit acquires the moving image and the still image. The moving image acquisition start instruction unit instructs to start acquisition of the moving image prior to acquisition of the still image. The time measuring unit measures a time from a start of acquisition of the moving image to acquisition of the still image. The moving image time determination unit determines a moving image time which is a time of the moving image included in the image.
Abstract:
An electronic device includes: a display unit capable of displaying a rotational pathway which rotates on a screen and with which an operation of the electronic device is associated according to a position on the rotational pathway; a touch screen that detects a touch from an outside and receives an input of a positional signal according to a position of the touch; a display controller that converts the position of the touch corresponding to the positional signal received by the touch screen into a position on the rotational pathway and causes a mark to be displayed at the position converted; and an operation controller that controls an operation of the electronic device according to a display position of the mark on the rotational pathway.
Abstract:
A driving device moves a movable lens in a plane direction intersecting at right angles with an optical axis to correct a shake. The driving device includes a movable frame which holds the movable lens, a fixed frame facing the movable frame, three balls held between the movable frame and the fixed frame, a single tension spring which pulls the movable frame toward the fixed frame to press the three balls, and VCMs which move the movable frame relative to the fixed frame. The tension spring is located inside a triangle that connects the centers of the three balls and outside a holding region where the movable frame holds the movable lens.
