Abstract:
A camera module can include a lens housing, an imaging unit and a driving motor. The lens housing can include a first lens module, a second lens module and a lens holder holding the first lens module and the second lens module. The imaging unit is located between the first lens module and the second lens module. The imaging unit is in optical alignment with the first lens module and the second lens module. The driving motor is coupled to the lens housing and configured to drive the lens housing to move relative to the imaging unit. When the driving motor drives the first lens module and the second lens module to move relative to the imaging unit, distance between the imaging unit and the first lens module is changed, or a distance between the imaging unit and the second lens module is changed.
Abstract:
An image projection apparatus (1) is an image projection apparatus in which an optical axis of a projection lens (19) for projecting an image and a center position of an image formation area on a light modulation element (32) may be displaced relative to each other, and the image projection apparatus includes electronic zoom means (13) for magnifying or reducing a size of the image formation area on the light modulation element by electronic zooming centered at a predetermined position, and control means (14) for controlling the electronic zoom unit to perform the electronic zooming with the predetermined position as the optical axis.
Abstract:
An image obtaining apparatus has a swing-type optical system, an optical dome and a correction optical system. The swing-type optical system is configured to adjust a photographing direction based on a swinging operation. The correction optical system corrects transmitted light beams through the optical dome to parallel light beams parallel to the photographing direction.
Abstract:
Panoramic and spherical cameras often currently capture respective portions of a scene using a set of lenses that focus images on imagers for sampling by photosensitive elements. Because the images are often circular and imagers are often rectangular, the orientation of the lenses may be selected as a tradeoff between capturing capture the entire image while leaving unused portions of the imager, and maximizing imager coverage to increase resolution while creating cropped image portions that extend beyond the edges of the imager. The techniques presented herein involve displacing the image from the imager center in order to increase a first cropped area and reduce or eliminate a second cropped area. The lenses may also be oriented such that the first cropped area comprises a portion of the composite image that may be acceptable to omit from the composite image (e.g., the user's hand or a camera mounting apparatus).

This invention relates to a method of manufacturing a display device, in particular a security document, comprising the steps of providing m images of an object, wherein m is at least equal to 2, dividing each image into n sets adjacent arrays (11,1, 11,2 . . . 11,n), . . . , (1m1, 1m2, . . . 1mn) of picture elements, spaced at a mutual distance δ, applying the images in an interlaced manner on an image layer in sets of interlaced arrays (111, 121 . . . 1m1), . . . , ( 11n, 12n . . . 1mn) below a lens structure comprising line-shaped lens elements over the image layer with one line shaped lens element overlying a corresponding set of adjacent arrays, characterised in that upon applying the arrays onto the image layer, and/or upon providing the lens elements, each array of picture elements is provided onto the image layer in an out of focus manner to form a blurred array or each array is imaged by the lens elements to form a blurred array, wherein a mutual distance of the edges of adjacent blurred arrays is smaller than the mutual distance δ.
Abstract:
A projection image display device includes a light source; an illumination optical system that uniformly irradiates a surface of an image modulating element (primary image surface) with a light beam emitted from the light source; and a projection optical system that performs with respect to a screen (a secondary image surface) extended projection on image information provided at the primary image surface and modulated by the image modulating element. The projection optical system includes a first optical system having a positive refractive power, and a second optical system having a concave reflecting surface. The first optical system has a common optical axis at which all optical components of the first optical system have rotationally symmetric surfaces, and a screen shift function that causes the secondary image surface to be moved by moving at least one of the optical components of the first optical system substantially perpendicularly to the optical axis.
Abstract:
A projector includes a projector body, a lens module with a lens, and a gear module. The lens module and the gear module are arranged in the projector body. The gear module is operable to adjust a height of the lens and keep an angle of the lens, in response to the gear module being rotated.
