LENS BARREL AND IMAGING DEVICE
A lens barrel has a dial operation member that adjusts an optical function of an imaging optical system, a restriction operation member having a first inclined surface inclined with respect to a movement direction from a release position toward a restriction position, and a cam member provided between the restriction operation member and the dial operation member and having a second inclined surface. In a case where the restriction operation member is moved to the release position, the dial operation member is put into a release state. In a case where the restriction operation member is in the restriction position, the cam member puts the dial operation member into a restriction state.
Lens control apparatus, lens control method, image capturing apparatus, information processing apparatus, information processing method, image capturing system, and computer readable storage medium
A lens control apparatus includes an operation input unit, a communication unit, and a control unit. The operation input unit is configured to accept a user operation. The communication unit is configured to perform communication with an external apparatus. The control unit is configured to perform driving control of a zoom lens in response to a zoom operation accepted by the operation input unit or a zoom control signal received by the communication unit. The control unit is also configured to selectively set a zoom position changing speed for driving control performed in response to the zoom operation and a zoom position changing speed for driving control performed in response to the zoom control signal, the zoom position changing speeds being different from each other.
Control apparatus for vibration motor, vibration apparatus having the same, and control method of vibration motor
A control apparatus to control a vibration motor includes a control unit. The vibration motor includes a vibration body and a contact body contacting the vibration body. The control apparatus applies alternating voltages, generated based on pulse width and frequency of pulse signals, to an electro-mechanical energy conversion element of the vibration motor to cause relative movement between the vibration and contact bodies at a target velocity. The pulse width and the frequency are (i) set such that a first steady velocity exceeds the target velocity, before the relative movement starts, and (ii) changed such that a second steady velocity is less than the first steady velocity, after the relative movement starts, and before an actual velocity at a time of the relative movement exceeds the target velocity. The pulse width or the frequency is controlled such that the relative movement is performed at the target velocity.
Lens module
The invention provides a lens module having a housing, and a focusing support frame, a first base, a second base, and a lens. The focusing support frame is provided with three first guide slots, and the first base is provided with three second guide slots. A first ball is provided between the first guide slot and the second guide slot. The first base is provided with three third guide slots, the second base is provided with three fourth guide slots, and a second ball is provided between the third guide slot and the fourth guide slot. Through stacked focusing support frame and relative movement between the first base and the second base, auto focus and optical image stabilization can be realized. The stable lens movement can be realized through the least number of guide mechanisms and the simplest structure.
Imaging element, imaging apparatus, imaging method, and program
An imaging element incorporates a reading portion that reads out captured image data at a first frame rate, a storage portion that stores the image data, a processing portion that processes the image data, and an output portion that outputs the processed image data at a second frame rate lower than the first frame rate. The reading portion reads out the image data of each of a plurality of frames in parallel. The storage portion stores, in parallel, each image data read out in parallel by the reading portion. The processing portion performs generation processing of generating output image data of one frame using the image data of each of the plurality of frames stored in the storage portion.
DRIVING DEVICE, CAMERA MODULE, AND PORTABLE TERMINAL DEVICE
An embodiment of the present invention relates to a driving device comprising: a second guide part; a first guide part disposed in the second guide part; an optical unit disposed in the first guide part; a first driving part disposed in the optical unit; and a second driving part disposed opposite to the first driving part, wherein the first guide part comprises: a first fixing part coupled to the second guide part; a first moving part connected to the optical unit; and a first connection part for connecting the first fixing part to the first moving part, and the optical unit is tilted about the first connection part by the first moving part.
OPTICAL APPARATUS, IMAGE STABILIZATION DEVICE, LENS BARREL, AND IMAGE PICKUP APPARATUS
An optical apparatus capable of adjusting a position of a lens with a simple configuration that enables miniaturization without deteriorating optical performance. Lens groups are arranged on an optical axis to be movable along the optical axis. A first shaft is arranged in parallel to the optical axis and has a fitting part fit in a predetermined lens group and a first fixing part. A support member rotatably supports the first shaft by holding the first fixing part. A center axis of the first fixing part and a center axis of the fitting part are eccentric. The first shaft is supported by the support member to be rotatable around the center axis of the first fixing part. The predetermined lens group is movable between an image pickup position on the optical axis and a retreat position that is separated from the optical axis by rotating around the first shaft.
