Abstract: Provided are a plenoptic microscope system having a structure in which a microlens array (MLA) is installed between an object and a microscope optical system and a general microscope camera is used as an image sensor, and an image processing apparatus for performing plenoptic imaging with information acquired from the same. In the plenoptic microscope system, an MLA including at least one microlens having a number of apertures (NA) similar to that of an objective lens of a microscope optical system is positioned at the front end of an incidence part of the microscope optical system and the objective lens is positioned at a focal length of the MLA or on an image plane of the MLA. The plenoptic image processing apparatus generates Plenoptic 1.0 and/or 2.0 images.

Abstract: An imaging system including an image acquisition device, a light-field imaging arrangement including an optical meta-device operable to facilitate imaging of a light-field of a target scene, and a structured-light imaging arrangement including an optical meta-device operable to facilitate generation of structured-light to be provided to a target scene to facilitate imaging of the target scene. The light-field imaging arrangement and the structured-light imaging arrangement are operably coupled with the image acquisition device such that the imaging system is selectively operable in, at least, a light-field imaging mode for performing light-field imaging of the target scene and a structured-light imaging mode for performing structured-light imaging of the target scene. The optical meta-device of the light-field imaging arrangement and the optical meta-device of the structured-light imaging arrangement may be provided by the same optical meta-device.

Abstract: A light-field optical image system with dual mode, having a main lens (103), a microlens array (102), an image sensor (101) and a first actuator (201) configured to cause a relative displacement between the image sensor (101) and the microlens array (102) to switch between at least two different optical configurations including: a light-field configuration, in which the image sensor (101) and the microlens array (102) are separated by a first distance (107a) that allows the image sensor (101) to capture a light-field image; and a 2D imaging configuration, in which the image sensor (101) and the microlens array (102) are separated by a second distance (107b), lower than the first distance (107a), that allows the image sensor (101) to avoid the light-field effect.

Abstract: A wearable display system including multiple cameras and a processor is disclosed. A greyscale camera and a color camera can be arranged to provide a central view field associated with both cameras and a peripheral view field associated with one of the two cameras. One or more of the two cameras may be a plenoptic camera. The wearable display system may acquire light field information using the at least one plenoptic camera and create a world model using the first light field information and first depth information stereoscopically determined from images acquired by the greyscale camera and the color camera. The wearable display system can track head pose using the at least one plenoptic camera and the world model. The wearable display system can track objects in the central view field and the peripheral view fields using the one or two plenoptic cameras, when the objects satisfy a depth criterion.

Abstract: Using the techniques discussed herein, a set of images is captured by one or more array imagers (106). Each array imager includes multiple imagers configured in various manners. Each array imager captures multiple images of substantially a same scene at substantially a same time. The images captured by each array image are encoded by multiple processors (112, 114). Each processor can encode sets of images captured by a different array imager, or each processor can encode different sets of images captured by the same array imager. The encoding of the images is performed using various image-compression techniques so that the information that results from the encoding is smaller, in terms of storage size, than the uncompressed images.

Abstract: Using the present solution, it is possible both to determine optical aberrations and/or the topography and to simultaneously or immediately successively record reference images of an eye. Within the scope of the method, the eye is illuminated with different illumination patterns by means of an illumination unit, and the light reflected by the eye is recorded by a plenoptic camera sensor and evaluated by a control and evaluation unit. According to the invention, the eye is illuminated with different illumination patterns which differ in respect of their intensity distribution and illumination direction, the light reflected by the eye is imaged onto the plenoptic camera sensor and the topography and/or optical aberrations and/or reference images of the illuminated eye are determined from the image data of the plenoptic camera sensor on the basis of the utilized illumination pattern. Even though the solution is especially provided for applications in ophthalmology, it can also be applied in other specialist fields and in industry.

Abstract: A stereo imaging system includes an optical assembly and a computational pixel imager (CPI) having a plurality of pixels. Each pixel includes a light sensor and counters that convert a photocurrent from the light sensor to a digital signal. The optical assembly, which directs light from a light field to the CPI, includes an optical field combiner and first and second primary lens assemblies, which are configured to receive first and second portions of the light from the lightfield, respectively, and to direct the first and second portions of the light to the optical field combiner. The optical field combiner includes a modulator configured to modulate the first and second portions of the light and to direct modulated first and second portions of the light onto the CPI. The counters are configured to perform digital signal processing on the digital signal.

Abstract: A multi-camera, multi-view light field endoscope simultaneously captures images of a body cavity using a plurality of camera sensors. The system makes use of input from an eye and head tracker to generate control signals selecting the specific pair of camera sensors that correspond to the user's eye and head position. By selecting only signals from the selected pair, transmission bandwidth, data rate, and system complexity are reduced. Use of the eye and head tracker give the user a look around, autostereoscopic capability with a simple, commercially available stereo display.
