A vision system includes a variable focal length (VFL) lens system, a light source, an exposure time controller and a camera. The VFL lens system includes a tunable acoustic gradient index of refraction (TAG) lens that is controlled to provide a nominally sinusoidal modulation of a focus position. The light source includes a continuous illumination source connected to a source driver that drives the continuous illumination source based on a quasi-sinusoidal periodic drive function to provide corresponding quasi-sinusoidal periodic intensity modulated light. The camera provides a workpiece image based on an image exposure that inputs workpiece image light that arises from illuminating the workpiece with the quasi-sinusoidal periodic intensity modulated light. Utilization of the quasi-sinusoidal periodic intensity modulated light in combination with the nominally sinusoidal focus position modulation results in uniform image exposures and other advantages (e.g., by avoiding over-exposure at the focus extremes of the TAG lens, etc.).

An electronic apparatus determines that only a first touch operation moved by a predetermined movement amount in a predetermined time period is a valid operation, and determines that another touch operation is an invalid operation, when a user captures an image while looking into a finder. Then, even when a movement amount by which the touch determined to be the valid operation once is moved in the predetermined time period falls below the predetermined movement amount, the electronic apparatus continuously determines that this touch is the valid operation. Even when a Touch-Up is performed regarding the touch determined to be the valid operation, the electronic apparatus continuously determines that the touch determined to be the invalid operation is the invalid operation.

The present disclosure includes an imaging control apparatus, an imaging control method, and an imaging apparatus. The imaging control apparatus includes a focal point detection control circuitry configured to receive first information from a range-finding area of a dedicated phase difference detection sensor and second information from a range-finding area of an image plane phase difference detection sensor, and detect a focal point based on at least one of the first information or the second information.

Embodiments provide a lens driving unit including a base, a housing supported so as to be movable relative to the base, a magnet located on the housing, a pattern coil part including a pattern coil that is located opposite the magnet, the pattern coil part being located on the base, and a sensor part mounted to the pattern coil part for sensing a position or movement of the housing, and the pattern coil part includes a first layer and a second layer stacked on the first layer, the sensor part being mounted underneath the first layer, and the pattern coil being formed on the second layer. Thereby, manufacturing costs may be reduced owing to a reduction in the number of elements, processes, and process management points.

Included are a display control unit configured to display a live view image being imaged by an imaging unit, and to display a display item indicating a degree of in-focus, superimposed on the live view image; an acquiring unit configured to acquire information relating to a degree of in-focus in a focus detecting region; and a changing unit configured to change display positions and display forms of a first indicator and second indicator that indicate a degree of in-focus by a positional display relationship with each other, and a third indicator that indicates a focus position, based on information acquired by the acquiring unit, the first indicator and the second indicator and the third indicator are included in the display item.

An image capture device, pixel, and method of determining a focus setting for an image capture device are described. The image capture device includes an imaging area and a pixel readout circuit. The imaging area includes a plurality of pixels. The plurality of pixels includes multiple pixels in which each pixel of the multiple pixels includes a two-dimensional array of photodetectors and a microlens. Each photodetector in the array of photodetectors for a pixel is electrically isolated from each other photodetector in the array of photodetectors. A microlens is disposed over the array of photodetectors for the pixel. The pixel readout circuit includes, per pixel, a shared readout circuit associated with the array of photodetectors for the pixel and a set of charge transfer transistors. Each charge transfer transistor is operable to connect a photodetector in the array of photodetectors to the shared readout circuit.

The present invention addresses a problem of providing a zoom lens which achieves a longer focal length and has a shorter optical overall length at the telephoto end, and an imaging apparatus provided with the zoom lens. In order to solve the problem, a zoom lens is configured to include, in order from the object side, a positive first lens group G1, a negative second lens group G2, a positive composite positive lens group, and a negative composite negative lens group. The composite positive lens group includes a positive third lens group G3, and is consisting of one or more lens groups having positive refractive power. The composite negative lens group includes a negative A lens group and a negative B lens group having negative refractive power. In the zoom lens, changing focal length is performed by varying distances between the lens groups, and a predetermined condition is satisfied.

A multiple-lens camera has only one image sensor to capture a number of images at different viewing angles. Using a single image sensor, instead of a number of separate image sensors, to capture multiple images simultaneously, one can avoid the calibration process to calibrate the different image sensors to make sure that color balance and the gain are the same for all the image sensors used. The camera has an adjustment mechanism for adjusting the distance between the image lenses, and a processor to receive from the image sensor electronic signals indicative of image data of the captured of images. The camera has a connector to transfer the processed image data to an external device or to an image display. The image display device is configured to display one of said plurality of images.

Examples herein relate to an electro-mechanical system for power cord detection, the system comprising a pin contained in a cavity of a receptacle adapted to receive a power cord, the pin comprising a first conductive pad, a second and a third conductive pads forming an open circuit and separated from the first conductive pad and an electrical circuit. The first conductive pad is adapted to be moved responsive to the power cord depressing the pin and the electrical circuit provides a first output responsive to the first conductive pad shorting the second and the third conductive pads.
