    Abstract: When a SW (113) is not pressed, fetched image data for one frame undergoes an MPEG compression process, and the compressed image data is temporarily stored in a buffer (107d). When the SW (113) is pressed, fetched image data for one frame undergoes a JPEG compression process, and image data for the next and subsequent frames undergo an MPEG compression process and are additionally stored at the end position of the buffer (107d). If a timer has reached a time-out, a JPEG file is generated based on JPEG-compressed data, and an MPEG file is generated based on MPEG-compressed data for a plurality of frames stored in the buffer (107d).

  • Publication number: 20030052995
    Abstract: One embodiment of the present invention provides a method and system for transforming a video bitstream in an interlaced format into a progressive format which can be displayed by a digital television. For example, the present embodiment utilizes the pixel information of a current field, previous field, and future field of the interlaced video bitstream to try to determine what the original content is of the missing lines of the current field. Specifically, the present embodiment utilizes different sets of pixel information in order to estimate the amount of motion that exist within a video bitstream. In this manner, the present embodiment is able to more closely determine the original value of the missing pixels of each field of the interlaced video bitstream. Therefore, the present embodiment provides a de-interlacing function enabling digital televisions to receive interlaced video bitstreams and display them in the progressive format.

  • Publication number: 20030052997
    Abstract: A phase-locked loop is provided which is operable to lock the sampling clock (pixel clock) to the incoming horizontal sync pulse contained within composite video information. Given the input signal is a VCR signal or a normal noise-free signal, there exists two modes of operation, coarse lock mode and fine lock mode, which are used in controlling the phase-locked loop. In the coarse lock mode, coarse corrections are made to a horizontal discrete time oscillator so that a fast lock may be achieve using the fine lock mode. Coarse corrections are based on a normalized sum of weighted pixels collected within a narrow gate window. Lock is achieved when the falling edge is centered within the window. Given the input signal is a television signal having noise, there exists one mode of operation where the flat window phase detector is used instead of coarse lock mode to bring the sync edge to fall within the window, where the flat window normalization constant is tuned.

    Abstract: Liquid crystal on silicon (LCOS) cells include a plurality of pixel elements formed between substrates. Spacers are formed on a portion of some of the pixel elements and positioned in the cell gap. The spacers on each of these LCOS cells reflecting different colors are formed in different locations in each cell. The result is that substantially none of the spacers create overlapping dead spots in a composite image. The spacers are further distributed among these pixel elements such that spacers are absent from some pixel elements and such that there is a substantially uniform thickness in the cell gaps. The reduced severity of the dead spots in the composite image as a result of the spacers in different locations, the reduced size and number of the spacers, and the uniformity in the cell gaps provide higher optical image quality.

  • Publication number: 20030053026
    Abstract: A scanning laser ophthalmoscope incorporates adaptive optics to compensate for wavefront aberrations in the eye. Light from a light source is scanned onto the retina. Light reflected from the retina is detected for imaging and is also used for wavefront sensing. The sensed wavefront aberrations are used to control an adaptive optic device, such as a deformable mirror, disposed in the path of the light from the source in order to compensate for the aberrations.

  • Publication number: 20030053028
    Abstract: An improved ophthalmic instrument including a wavefront sensor that estimates aberrations in reflections of the light formed as a spot image on the retina of the human eye, wherein the wavefront sensor includes at least one subaperture that spatially samples incident light; at least one optical element that focuses each sample to a spot; and an image sensor and image processor for measuring location of the spot. The image sensor captures image data of an pixel subaperture defined around the spot and provides the image data to the image processor. The image processor analyzes the image data to identify a subarray of pixels around a peak in the pixel subaperture, fits a predetermined function to the image data for the subarray of pixels, and derives an estimate for spot location based upon location of the fit of the predetermined function.

    Abstract: An improved ophthalmic instrument including a wavefront sensor that estimates aberrations in reflections of the light formed as a spot image on the retina of the human eye. The wavefront sensor includes a beam splitter operably disposed between a lenslet array and multiple imaging devices. The lenslet array forms a first array of spots, and the multiple imaging devices capture multiple images of the first array of spots for use in estimating the aberrations of the eye in a manner that minimizes the adverse effects of eye movement on the accuracy of such estimates. The beam splitter preferably comprises a prismatic beam splitter that splits light incident thereto into multiple arms. The multiple image devices may capture at least a first image of the first array of spots at best focus and a second image of the first array of spots near best focus for use in dynamically identifying sub-arrays (pixel areas) of the Hartmann spot imaging device (e.g.

    Abstract: An improved ophthalmic instrument including a wavefront sensor that estimates aberrations in reflections of the light formed as an image on the retina of the human eye. A phase compensator, operably coupled to the wavefront sensor, spatially modulates the phase of incident light to compensate for the aberrations estimated by the wavefront sensor. The phase compensator includes a first stage and at least one other additional stage, wherein the first stage compensates for a defocus component of the aberrations, and the additional stage(s) compensate for other higher order components of the aberrations. The first stage preferably comprises a variable focus lens and the additional stage(s) preferably comprise a deformable mirror.

    Abstract: A field flattener having a function of flattening a bent image surface on which an image is formed through an optical system, is composed of a material of which a refractive index is equal to or larger than 2. A sectional configuration of the field flattener cut in an optical-axis direction containing the optical axis is formed to take a stepped shape toward its peripheral edge from the optical axis. An axial height of the stepped portion configuring the surface in the optical-axis direction in this stepped shape is set so as to equal to or larger than twice a wavelength of beams to be used.

    Abstract: An aerial projection system and method having a housing for positioning low cost optical elements capable of generating a three dimensional aerial images at video rates without reflected artifacts or visible display of the display screen. A method for generating the display images is based on a set of rules that eliminate boundary transgressions and maximizes the illusion of a three dimensional aerial image. An optional second display is a transparent imaging panel that acts selectively as a light valve, as a display platform for special effects or for providing the appearance of linear motion towards or away from the observer. An optional third display, also a transparent imaging panel, may be used as a background display device for displaying video rate images that are not projected aerial images.
