Abstract:
A built-in flash pop-out mechanism comprises a shaft member movable along a first axis; an arm member where one end is pivotally fixed at an end of the shaft member about a second axis; a flash-support member pivotally fixed at the other end of the arm member about a third axis; a first biasing member biasing the shaft member along the first axis; a second biasing member biasing the arm member about the second axis; a third biasing member biasing the flash-support member about the third axis. The built-in flash is extended from a camera body with coplanar motions that pop out the built-in flash to increase its distance from an optical axis. The motions include a translation of the shaft member along the first axis and rotations of the arm member and flash-support member about the second and third axes.
Abstract:
A digital camera includes an imaging system which performs a photographing operation and records captured image files in a buffer memory; an AF system which performs a focus-state detection process, in which the AF system detects a focus state, and a focusing lens group driving process, in which the AF system moves a focusing lens group to an in-focus position; and first and second switches which actuate the AF system and the imaging system, respectively. While the first and second switches are held ON, the digital camera performs a continuous shooting process in which the imaging system repeatedly performs the photographing operation and the AF system repeatedly performs the focus-state detection process. Upon the buffer memory becoming full during the continuous shooting process, the imaging system suspends the photographing operation and the AF system performs the focus-state detection process and the focusing lens group driving process.
Abstract:
A photographic apparatus comprises a monitor, a face detector, and an electronic zoom controller. The monitor displays a first through-image based on image data. The face detector performs face detection on an image of an area displayed on the monitor, based on the image data. The electronic zoom controller performs first electronic zoom control that enlarges and displays a second through-image corresponding to a predetermined area including a face area detected by the face detector, to the size of a display area of the first through-image, on the monitor. The electronic zoom controller performs second electronic zoom control that enlarges and displays an intermediate through-image corresponding to an intermediate area including the predetermined area and larger than the predetermined area, to the size of the display area of the first through-image, on the monitor, before performing the first electronic zoom control.
Abstract:
A zoom lens system includes a positive first lens group, a negative second lens group, a positive third lens group, and a positive fourth lens group, in this order from an object. Upon zooming from the short focal length extremity to the long focal length extremity, the distance between the first and the second lens groups increases, and the distance between the second and the third lens groups decreases. The third lens group includes a positive first sub-lens group and a negative second sub-lens group, in this order from the object. The first sub-lens group comprises a positive lens element provided at the most object-side thereof and a cemented lens provided at the most image-side thereof. The cemented lens includes a positive lens element and a negative lens element, in this order from the object.
Abstract:
A variable power lens, having first and second lens groups, includes first and second lens group support frames, a linear guide ring, first and second lens group drive rings which rotate to move the first and second lens group support rings in the optical axis direction relative to the linear guide ring, a drive ring coupler which couples the first and second lens group drive rings with each other to prevent relative rotation therebetween while allowing relative movement therebetween in the optical axis direction; and a drive-ring movement controller which integrally rotates the first and second lens group drive rings via the drive ring coupler without relatively moving in the optical axis direction when a power-variation operating member is operated, and moves one of the first and the second lens group drive rings in the optical axis direction without rotating when a focus operating member is operated.

Abstract:
An imager is provided having an imaging sensor and a focusing detector. The imaging sensor reads stored charges in a positive or negative direction and outputs image data created from the read charges. The comparator calculates a differential between first image data output by said imaging sensor and second image data output by the imaging sensor immediately after the first image data is output, and determines whether the differential is larger than a first threshold value. The composer creates composite image data from the data of two images output by the imaging sensor. When the comparator determines that the differential is larger than the first threshold value, the composer creates composite image data from the second image data and negatively scanned image data that is obtained by scanning the second image in a direction that is opposite to the scanning direction of the second image data.
Abstract:
A catalog page generation system, comprising a first generation circuit, a first determination circuit, and a second generation circuit, is provided. The first generation circuit generates a catalog page of objects included in a first directory or a first folder. The first determination circuit determines whether or not a second directory different from the first directory or a second folder different from the first folder exists. The second generation circuit generates existence information if the first determination circuit determines that the second directory or the second folder exists. The existence information indicates the existence of another directory or another folder of the same level as the first directory or the first folder.
Abstract:
An imager is provided having an image-capturing device, a display, and a view angle controller. The image-capturing device captures a subject image and outputs an image signal. The display displays a through image consisting of multiple images continuously displayed. The view angle controller controls a view angle of an image so that a ratio of an area of a subject in an area of an image is maintained at a certain value when the display displays a through image.
Abstract:
A focus detection optical system includes a condenser lens positioned behind an expected image plane of a photographing lens, an auxiliary lens positioned behind the condenser lens, and a separator lens including a pair of lenses behind the auxiliary lens. An object image formed on the expected image plane is divided into two images by the pair of lenses and reformed on a pair of areas on a sensor.
