Abstract: A video camera constructed according to one aspect of the focus adjustment device moves a focus lens forward and backward and detects peak values of an AF evaluation value of the focus lens in the forward moving direction and in the backward moving direction. The video camera calculates a correction value based on a difference between the peak value of the evaluation value detected in the forward motion of the lens and the peak value of the evaluation value detected in the backward motion of the lens. The video camera corrects the AF evaluation value with the calculated correction value and detects a focused position of the lens based on the corrected AF evaluation value in moving the lens.

Abstract: In the zoom lens, the second lens group includes at least one surface that is an aspheric surface, and during changing magnification, the second lens group, the third lens group, and the fourth lens group are respectively capable of moving independently, with the position of the aperture moving along a convex trajectory on the optical axis from the image side to the object side during changing magnification.

Abstract: In the imaging apparatus of the invention, a camera assembly 200 including a camera 202 is mounted on and supported by a base 110 in a pivotally rotatable manner in a vertical direction to allow tilting motions of the camera 202. First through fourth rollers 141 through 144 provided in an assembly fixation structure 114 of the base 110 support the camera assembly 200 to allow pivotal rotation of the camera assembly 200. The driving force of a tilting motor 160 built in a pedestal plate unit 130 of the assembly fixation structure 114 is transmitted to frame side faces of the camera assembly 200 via a tilting worm gear shaft 170 and a tilting rotation gear 172 to allow the tilting motions of the camera frame 200. This arrangement of the invention enables further downsizing of the whole imaging apparatus applied to, for example, a security camera.

Abstract: In an imaging device according to one aspect of the invention, an amplitude demand Ac is specified according to a wobbling amplitude Ai required for detection of a hill-climbing direction based on an F value and a wobbling amplitude Ag required for detection of the hill-climbing direction based on an AGC gain. An allowable amplitude Am set for preventing a potential image shake caused by a magnification change with a position shift of a compensator lens in wobbling is specified corresponding to a zoom position and an object distance. When Ac>Am, the control procedure restricts the wobbling amplitude to Am and increases a sampling number of AF evaluation values to be detected at respective positions in wobbling, in order to ensure the sufficient detection performance of the hill-climbing direction. When Ac?Am on the other hand, the control procedure sets Ac to the wobbling amplitude.

Abstract: In response to the user's short press of one preset button, a video camera according to one aspect of the invention reads out preset values stored in an EEPROM and adjusts the pan position, the tilt position, the position of a zoom lens, the position of a focus lens based on the read-out preset values. A movable range of the focus lens is restricted to a specific limited range between a closer direction end and a background position as a previously focused position. Hill-climbing control is then performed in this restricted movable range. This arrangement effectively ensures quick adjustment of the focus position of the video camera.

Abstract: The zoom lens 100 comprises, sequentially from the object side, a stationary first lens group 110 having positive refractive power; a second lens group 120, having negative refractive power, and that moves on the optical axis when changing the magnification; a stationary third lens group 130 that has positive refractive power; and a fourth lens group 140, having positive refractive power. The first lens group 110 comprises six lenses. The second lens L2 is a meniscus lens that is formed so as to have at least one aspherical surface. The aspherical surface of the second lens L2 is formed at the shape wherein there is no displacement in the thickness from the center portion to the edge portion. Doing so enables the effective correction of distortion and off-axis aberration on the wide-angle side, and the provision of a high-performance zoom lens that is small and has a high variable magnification.

The light emitted by the LED light source 160L2 and the LED light source 160R2 lying towards the center zone of the light source array where the light source placement has been thinned out will be reflected by a left outside wall face 171LS and a right outside wall face 171RS respectively, and directed onto the table upper face.

Abstract: An imaging apparatus includes an arm unit that is configured to be inclinable to a table. The imaging apparatus varies the extent of inclination to change an imaging attitude of the video camera between a faraway imaging attitude that is most distant from the table surface and a nearby imaging attitude that is most close to the table surface. When the imaging attitude of the video camera is changed as above, an illumination link mechanism in the imaging apparatus causes a swing motion of a first group of illumination LED and changes a spot to be illuminated by the first group of illumination LED in compliance with the change of the imaging location of the video camera, which changes the imaging attitude.

Abstract: To make more effective use of the circumference of arm rotation while assisting the arm rotation in terms of the rotatability of an arm that holds a camera head, resulting in a more compact device. The imaging device 100 holds a camera head 120 against a table 110 by means of a camera holding arm 140, and the camera holding arm 140 is axially supported rotatably so that the degree of incline relative to the table 110 is variable. A coil spring 260 is incorporated in a through hole 203b, as well as a recess 143k continuous therewith, about the axis of a first subaxial pin 220 aligned with the axis of the arm axial support. The coil spring 260 assists rotation by building up coil spring stress while the camera holding arm 140 (base 143) rotates toward the table 110, and by allowing the coil spring stress to be exerted in the form of assisting force on the arm when the base 143 rotates in such a way that the angle of incline with the table 110 expands.

Abstract: The presentation device 100 comprises a shuttle operation member 170 rotatable in the forward and reverse directions. The shuttle operation member 170 comprises a momentary mechanism, returning automatically to the neutral position when the user releases the hand. When a sub-microprocessor 360 inputs from the shuttle operation member 170 signals representing operating direction and operating angle, on the basis of these signals, it determines a zoom direction and zoom speed, and by giving an instruction to a lens control microprocessor 127 or a picture signal processor IC 300, performs optical zoom or digital zoom. By means of this correction, operability in zoom operations in the presentation device is improved.

Abstract: An imaging apparatus that outputs an image of an object taken by an imaging device to an external display device is disclosed. The imaging apparatus includes a main body, a lid serving as a leg to support the main body, and electronics devices such as a controller within the main body. The lid is rotatably engaged with one end of the main body. In a first configuration, the lid overlaps the main body, and in a second configuration the lid and the main body form a V-shape, such that one end of the lid is separated from the main body. In the second configuration, the main body stands tilted and is supported by the lid, such that they straddle a top surface of the object supporter such as desktop. The imaging unit may thus be pointed toward the object located in the straddled region.

Abstract: Usability of device is improved for an imaging device that images a target object mounted on a table. In order to hold a camera head 120 and an illumination unit 130 with respect to a table 110 on which a target object is mounted, an imaging device 100 coaxially and rotatably supports a camera head holding arm 140 and an illumination unit holding arm 150 at an elevated portion 118, which is located at an inner-left corner of the table 110, such that degrees of inclinations of the arms may be variable with respect to the table 110. The arms are rotatably and axially supported at the elevated portion 118 such that the camera holding arm 140 can rotate with an accompanying rotation of the illumination unit holding arm 150 and the illumination unit holding arm 150 can rotate independently with no accompanying rotation of the camera holding arm 140.

Abstract: A camera-assisted presentation apparatus, which is one of imaging apparatuses, has a table including a fixation member and two extension members, and a camera support assembly with a video camera attached to one end thereof. The two extension members are attached to the fixation member in a pivotally rotatable manner. In a service state of the camera-assisted presentation apparatus, the fixation member and the two extension members are extended to form one identical plane and ensure a wide area, on which a material for presentation is mounted. In a non-service state of the camera-assisted presentation apparatus, the two extension members are folded down to a camera holder member and an arm member of the camera support assembly. This arrangement significantly reduces the whole size of the camera-assisted presentation apparatus in its non-service state and effectively enhances the portability of the camera-assisted presentation apparatus.
