Spatially differentiated luminance in a multi-lens camera
Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different modulation transfer functions defining varying sharpness based on location within the field of view. The image information received from each lens can be combined to form an image based on the sharpness of the image information received from each lens.
Image pickup apparatus capable of selectively picking up a color image and a black-and-white image
Provided is an image pickup apparatus comprising: a light control mirror element (ace CME) having a function of splitting an incident light flux (LF) into a first LF from reflection and a second LF from transmission and a function of switching between a semi-transmissive/semi-reflective state (s-t/s-rS) and a totally reflective state (TRS); a LF splitting unit causes first and second LFs to be emitted from first and second exit surfaces (ES), respectively; an electrochromic element (EE) switches between a state of transmitting light having a first wavelength range (WR) out of first LF (first state) and a state of transmitting light having a second WR out of first LF (second state); and a control device conducts switching control between a first mode in which LCME is in s-t/s-rS and EE is in first state and a second mode in which LCME is in TRS and EE is in second state.
Systems and Methods for Lensed and Lensless Optical Sensing
A sensing device with an odd-symmetry grating projects near-field spatial modulations onto an array of closely spaced pixels. Due to physical properties of the grating, the spatial modulations are in focus for a range of wavelengths and spacings. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. Pixels responsive to infrared light can be used to make thermal imaging devices and other types of thermal sensors. Some sensors are well adapted for tracking eye movements, and others for imaging barcodes and like binary images. In the latter case, the known binary property of the expected images can be used to simplify the process of extracting image data.
HD Color Imaging Using Monochromatic CMOS Image Sensors Integrated In 3D Package
HD color video using monochromatic CMOS image sensors integrated in a 3D package is provided. An example 3DIC package for color video includes a beam splitter to partition received light of an image stream into multiple light outputs. Multiple monochromatic CMOS image sensors are each coupled to one of the multiple light outputs to sense a monochromatic image stream at a respective component wavelength of the received light. Each monochromatic CMOS image sensor is specially constructed, doped, controlled, and tuned to its respective wavelength of light. A parallel processing integrator or interposer chip heterogeneously combines the respective monochromatic image streams into a full-spectrum color video stream, including parallel processing of an infrared or ultraviolet stream. The parallel processing of the monochromatic image streams provides reconstruction to HD or 4K HD color video at low light levels. Parallel processing to one interposer chip also enhances speed, spatial resolution, sensitivity, low light performance, and color reconstruction.
Luminance source selection in a multi-lens camera
The luminance information of an image captured by a multi-lens camera system can be improved by selecting a luminance information source for each portion of the captured image. Each lens of the camera system can capture an initial image. For each portion of a final image, a corresponding initial image portion can be selected as the luminance information source. The portions of the final image and initial images can be pixels, groups of pixels, or other image portions. The luminance information from the selected initial image portions is combined to form final image luminance information. Chrominance information can also be selected from the initial images to form final image chrominance information, and the final image chrominance information and the final image luminance information can be combined to form a final image.

HIGH RESOLUTION THIN MULTI-APERTURE IMAGING SYSTEMS

The second sensor may have either Clear or standard CFA covered sections. Either image may be chosen to be a primary or an auxiliary image, based on a zoom factor. An output image with a point of view determined by the primary image is obtained by registering the auxiliary image to the primary image.
