Abstract:
A system and method for generating multiple images with rich color acquisition using a plenoptic camera having a main lens disposed in front of a micro array of lenses, a mosaic color filter array and an image sensor, characterized in that it comprises: capturing a first set of images using an ordinary state of an electrically controllable birefringent medium being disposed between said main lens and said micro array of lenses, said ordinary state providing an ordinary ray to each pixel; capturing a second set of images using an extraordinary state of said electrically controllable birefringent medium, said extraordinary state splitting the light from said main lens into an ordinary ray and a extraordinary ray respectively impinging on two adjacent pixels of different colors, said extraordinary ray being shifted by distance of one pixel on said image sensor; performing a weighted subtraction of information about said second set of images from information about said first set of images; and generating a final set of images with rich color information from said weighted subtraction and said first set of images.

Abstract:
Method and devices are disclosed for focusing on tilted image planes. For example, one imaging device includes an objective lens configured to focus a scene at an image plane, the scene having an object plane tilted relative to the objective lens plane and a sensor receive light from the objective lens, the sensor having a plurality of light sensing elements configured to generate image data based on the light received at the sensor. The imaging device also includes a processor and memory component configured to receive the image data, the image data indicative of a first image; receive a tilt parameter indicative of an orientation of a selected non-parallel image plane, and convert the image data to relative image data based on the tilt parameter, the relative image data indicative of a second image focused along the non-parallel image plane.
Abstract:
In an image capturing apparatus, an image sensing device includes a plurality of groups of pixels each including a plurality of photoelectric conversion elements, signals from the plurality of photoelectric conversion elements being readable separately for each photoelectric conversion element via a signal line used in common by each group of pixels. A reading unit performs, on a plurality of groups of pixels, a reading-out operation to reading out a signal as a first signal from part of the plurality of photoelectric conversion elements and a second reading-out operation to mix signals from the plurality of photoelectric conversion elements and read out a resultant mixed signal as an image signal. A generation unit generates one image file including the first signal, the image signal, and defect data indicating a group of pixels for which the first signal is defective while the image signal is not defective.
Abstract:
Various image capture control methods and apparatuses are disclosed. An image sensing unit can be inclined relative to an initial normal line, to change a ratio of pixels distributed along two directions in an effective region of the image sensing unit in which light through a lens that is in an imaging system and corresponds to the image sensing unit is imaged on the image sensing unit. The two directions are perpendicular to the initial normal line and orthogonal to each other, the image sensing unit comprises pixels distributed in array, and the pixels are used for recording multidirectional view information of a same object of a scene. An image of the scene is captured using the imaging system. Proportions of parallax information actually recorded by the image sensing unit in the two directions can be changed, and differential capture of view information in different directions can be implemented.
