Abstract: The invention relates to multicore fiber imaging, such as used in endoscopy. Methods are described for processing images captured with such systems to achieve an improved depth of field image or extract 3D information concerning the images, without requiring the addition of additional optical components.
One method for generating an image from light received by an imager via a multiplicity of waveguides includes receiving a digital image containing a plurality of pixels, the digital image including a plurality of regions within it wherein each of said regions corresponds to a waveguide core. Each region includes a plurality of pixels, and a first subset of pixels within each region is defined which at least partly correlates with light having been received at a corresponding core in a first spatial arrangement, the subset including less than all of the pixels within a region. A first image is generated from the first subset of pixels from said regions, combined to form an image over the whole waveguide array. The first spatial arrangement may correspond to a measure of angular dimension of the incident light for that region.
In addition to increased depth of field, the modified images provided by the invention allow 3D visualisation of objects, eg. using stereographs or depth mapping techniques.

Abstract: The disclosure describes various aspects of an architecture for light emitting elements in a light field display. In an aspect, a light field display can include multiple picture elements (e.g., super-raxels), where each picture element includes multiple sub-picture elements monolithically integrated on a same semiconductor substrate. Each sub-picture element has a respective light steering optical element and includes an array of light emitting elements (e.g., sub-raxels) that produce the same color of light. The light steering optical element can include at least one microlens, at least one grating, or a combination of both. Separate groups of light emitting elements can be configured and a directional resolution of the light field display can be based on the number of groups. The light field display also includes electronic means configured to drive the light emitting elements in each sub-picture element.

Abstract: According to various embodiments, an electronic device including at least one camera module is provided. The electronic device comprises: a lens unit; and an image sensor that can image light that has passed through the lens unit and convert same into a digital signal. The image sensor comprises: a micro lens array unit composed of a plurality of regularly-arranged micro lenses that can image at least a portion of the light on a specific light receiving element; at least one type of spatially divided color filter array unit that is composed of a plurality of colors and can selectively transmit light; a light receiving unit composed of a plurality of light receiving elements that convert, into an electrical signal, light of a wavelength selectively incident from the color filter array unit; and a data calculation unit that calculates the electrical signal of the light receiving unit. The one color filter corresponds to the one micro lens, and a plurality of sub-light receiving units including at least one light receiving element correspond to the one micro lens. The plurality of sub-light receiving units may comprise: a first sub-light receiving unit for receiving a first light beam of incident light; a second sub-light receiving unit that is disposed side by side with the first sub-light receiving unit in a first direction and receives a second light beam adjacent to the first light beam of incident light; and a third sub-light receiving unit that is disposed in the direction opposite the first direction with respect to the first sub-light receiving unit and receives a third light beam adjacent to the first light beam of incident light. Various other embodiments are possible.
