CONTROL DEVICE, OPERATION METHOD FOR CONTROL DEVICE, AND STORAGE MEDIUM
A control device that controls imaging with fisheye cameras disposed on front and rear portions and right and left side portions of a vehicle, the control device comprising: a detection unit configured to detect an orientation of the vehicle; and a control unit configured to control a conversion center position for converting a fisheye image of each of the fisheye cameras into a planar image based on the orientation of the vehicle.
OPTICAL NON-UNIFORMITY COMPENSATION (NUC) FOR PASSIVE IMAGING SENSORS USING MICRO-ELECTRO-MECHANICAL SYSTEM (MEMS) MICRO-MIRROR ARRAYS (MMAS)
A passive imaging sensor includes a plurality of optical elements in which at least one includes one or more Micro-Electro-Mechanical System (MEMS) Micro-Mirror Arrays (MMAs) having a plurality of independently and continuously controllable mirrors that at least tip and tilt in 2 DOF and may tip, tilt and piston in 3 DOF. In an operational mode, the mirrors are tipped and tilted, and possibly pistoned, such that the optical radiation is focused at the pixelated detector to read out an image of the scene. NUC coefficients such as offset and/or gain are applied to either the output signals of the detector or to the image to form the NUC'd images. In a calibration mode, the mirrors are tipped and tilted and/or pistoned to spatially or temporally blur the image or to re-direct the FOV to one or more on-board calibration sources to generate a uniform image from which to calculate and update the NUC coefficients.
OPTICAL SYSTEM WITH DYNAMIC DISTORTION USING FREEFORM ELEMENTS
A method for designing an optical system for providing reliable, robust and successful realization of a distortion variation function is presented. In a preferred embodiment, the proposed distortion variation optical system includes at least two non-symmetrical elements, which are moving in the transverse direction. The proposed freeform lens contains two transmissive refractive surfaces. The freeform elements designed with this method have preferably a flat surface and a non-symmetrical freeform surface. The two plano-surfaces are preferably made to face each other, so that a miniature camera can be offered. The value of the non-symmetrical freeform surface is used to produce variable optical power when the two freeform elements undergo a relative movement in the vertical direction. Using this method, an optical system with an active distortion, smaller form factor, and better imaging quality can be obtained.
Electronic device and method for adjusting color of image data by using infrared sensor
An electronic device and a method for adjusting a color of image data by using an infrared sensor are provided. The electronic device includes a lens, an infrared filter, an image sensor, an infrared sensor and at least one processor operably coupled to the image sensor and the infrared sensor. The at least one processor receives image data that is based on external light passing through the lens and the infrared filter and arriving at the image sensor, from the image sensor, and identifies an intensity of infrared light included in the external light, at least based on sensor data of the infrared sensor, and in response to the identifying of the intensity of the infrared light, adjusts a color of at least portion of the image data at least based on the intensity of the infrared light.
Spectral camera with integrated filters and multiple adjacent image copies projected onto sensor array
A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, an optical duplicator, an array of filters, and a sensor array arranged to detect the filtered image copies simultaneously on different parts of the sensor array. Further, a field stop defines an outline of the image copies projected on the sensor array. The filters are integrated on the sensor array, which has a planar structure without perpendicular physical barriers for preventing cross talk between each of the adjacent optical channels. The field stop enables adjacent image copies to fit together without gaps for such barriers. The integrated filters mean there is no parasitic cavity causing crosstalk between the adjacent image copies. This means there is no longer a need for barriers between adjacent projected image copies, and thus sensor area can be better utilized.
Low profile camera module with image compensation
A low-cost resin lens is disclosed for use in miniature cameras. The resin lens features a low profile that is particularly well-suited to consumer products such as smart phones. The resin lens is mounted to an integrated circuit die that is attached to a standard four-layer substrate. The integrated circuit die includes electronic and/or optoelectronic circuits to support digital image capture, transfer, and processing. Image correction software adjusts the image to correct for distortion introduced by the resin lens.
