Publication number: 20130242080Abstract: A hermetically sealed digital electronic camera that is designed to operate both on land and underwater to great depths, and method of making same. The present invention is a camera which is hermetically sealed by being totally encapsulated, preferably by being cast in plastic, with no seals, holes, joints, penetrating pins, wires or other objects. Wireless means are used for communicating information, electrical power and control signals. The invention is impervious to atmospheric contamination and absolutely incapable of leaking under water to great depths and pressures. In an alternate embodiment camera optics are not encapsulated but are immersed in water when the encapsulated digital camera is placed in water.Type: ApplicationFiled: December 10, 2012Publication date: September 19, 2013Applicant: DIGITALOPTICS CORPORATION INTERNATIONALInventor: Philip Kossin

Patent number: 8537234Abstract: A method for imaging includes receiving an input image that includes a matrix of pixels (32) having input pixel values. The input pixel values are processed so as to detect a region of saturation in the input image. A first image filtering operation is applied to the input pixel values of at least the pixels that are outside the region of saturation, so as to generate first filtered pixel values. A second image filtering operation is applied to the input pixel values of at least the pixels that are within the region of saturation, so as to generate second filtered pixel value. An enhanced output image is generated by stitching together the first and second filtered pixel values.Type: GrantFiled: May 6, 2008Date of Patent: September 17, 2013Assignee: DigitalOptics Corporation InternationalInventors: Anatoly Litvinov, Yoav Lavi, Uri Kinrot

Patent number: 8310587Abstract: Imaging apparatus includes an image sensor, which is adapted to generate an input image in response to optical radiation that is incident thereon. A processing engine is configured to apply a digital filter to the input image so as to generate a filtered image, the digital filter having a kernel, which has a kernel width that is greater than five pixels. An optical assembly is arranged to focus the optical radiation onto the image sensor with a point spread function (PSF) such that no more than a first threshold percentage of energy emitted from a point object and focused by the optical assembly falls within a first region of the image sensor having a first width that is five times the pitch of the image sensor, while at least a second threshold percentage of the energy emitted from the point object and focused by the optical assembly falls within a second region, which contains the first region and has a second width corresponding to the kernel width.Type: GrantFiled: December 3, 2008Date of Patent: November 13, 2012Assignee: DigitalOptics Corporation InternationalInventors: Ziv Attar, Yoav Yadin, Alex Alon

Patent number: 8154636Abstract: An image enhancement circuit (26, 60, 190, 260) includes an input interface (64, 262), which is operative to accept a stream of input pixel values belonging to pixels (32) of an input image. The input image includes a plurality of different input sub-images including respective subsets of the pixels, such that the input pixel values of the pixels in the different input sub-images are interleaved in the stream. A plurality of filter cells (92, 144, 206, 222, 238, 364) are connected in a two-dimensional array configuration and are arranged to separately filter the input pixel values of each of the input sub-images with respective two-dimensional deconvolution kernels so as produce respective output sub-images that include output pixel values. A multiplexer (88, 332) is coupled to multiplex together the output pixel values of the output sub-images so as to produce a filtered output image.Type: GrantFiled: December 17, 2006Date of Patent: April 10, 2012Assignee: DigitalOptics Corporation InternationalInventors: Elchanan Rappaport, Yoav Lavi, David Drori, Uri Kinrot
