An image processing apparatus includes an image display element, an instruction position detection unit for accepting an instruction operation from a user through an operation face provided to a display screen of the image display element and detecting and outputting an instruction position of the instruction operation with respect to the operation face, a storage unit for storing and holding image data of images, and a display control unit for performing a control for displaying an image in accordance with the stored and held image data on the image display element, in which when the user performs a continuous movement on the operation face, the display control unit performs a control for scrolling the display image while being reduced together with images before and after the display image in accordance with a direction of the operation determined on the basis of a detection output from the instruction position detection unit.

In the systems and methods of the present invention a multifocal multiphoton imaging system has a signal to noise ratio (SNR) that is reduced by over an order of magnitude at imaging depth equal to twice the mean free path scattering length of the specimen. An MMM system based on an area detector such as a multianode photomultiplier tube (MAPMT) that is optimized for high-speed tissue imaging. The specimen is raster-scanned with an array of excitation light beams. The emission photons from the array of excitation foci are collected simultaneously by a MAPMT and the signals from each anode are detected using high sensitivity, low noise single photon counting circuits. An image is formed by the temporal encoding of the integrated signal with a raster scanning pattern. A deconvolution procedure taking account of the spatial distribution and the raster temporal encoding of collected photons can be used to improve decay coefficient. We demonstrate MAPMT-based MMM can provide significantly better contrast than CCD-based existing systems.

An in-camera two-stage compression implementation is described that reduces the latency between snapshots to a fraction of that otherwise required by other systems that either process complete compression following each snapshot or that incorporate heavy, bulky, and expensive RAM hardware capable of maintaining several raw luminosity records (unprocessed file containing a digital image). In the 1st stage compression the raw luminosity record is quickly, yet partially, compressed to available RAM buffer space to allow a user to expeditiously capture a succeeding image. When the higher-priority processes, the user shooting pictures, and stage one compression subside, a 2nd stage compression, which is slower but more effective, decompresses the earlier partially-compressed images, and re-compresses them for saving in flash memory until they are distributed to a remote platform to be finally converted to the JPEG2000 format.

The present invention describes methods and cassettes for cell-based toxin detection and organ localization. The cassettes includes an array containing cells and a matrix of openings or depressions, wherein each region of the substrate enclosed by the opening or depression in the matrix forms a domain individually addressable by microfluidic channels in the device.

A video stream may be edited such that hot spots and their attributes may be added to the video stream. Hot spots and their attributes may be stored in a generic database. A translator may generate the hot spot information in a specific code for a specific application, such as properly formatted for a specific set top box hardware configuration, a specific language, or a specific look and feel of the hot spots. Additionally, a template may be used to define selected parameters of the hot spots, and the template may be changed such that the translator can create enhanced video streams in several different formats based on the templates.

A method for simulating aerial images is provided where the integrand of a transmission cross-coefficient (TCC) integral is formed from defocused paraxial pupil transfer functions, and contour integration is performed over the boundary of the intersection of the offset pupil functions and the source function. Preferably, the paraxial pupil functions are approximated by a second order Taylor series expansion. The integrand is preferably parameterized in terms of the angles subtending the arcs of the boundary of the integration region, and the integrand is further approximated by an expansion of analytically integrable terms having an error term that substantially monotically decreases as the number of expansion terms increases. Additional factors such as aberrations and amplitude variations can be included by using functions that are simply multipied with the defocused paraxial pupil functions in the integrand. The integrands provide fast computations of TCC integrals that are accurate to within a desired tolerance.

The invention comprises a robotic microscope system and methods that allow high through-put analysis biological materials, particularly living cells, and allows precise return to and re-imaging of the same field (e.g., the same cell) that has been imaged earlier. This capability enables experiments and testing hypotheses that deal with causality over time intervals which are not possible with conventional microscopy methods.

A wide-angle zoom lens with as few as two plastic elements codes the wavefront produced by the imaging system such that the imaging system is substantially invariant to aberrations related to misfocus. Signal processing is used to decode the wavefront to form the final image. A first type of zoom lens configuration uses as few as two lens elements. In this type, image processing may be modified to take into account the positioning of the lenses.

There is provided an image-taking method and apparatus capable of quickly taking an image in which a human face is in focus. When an instruction to take an image is input, multiple images are taken with different focus positions. A human face in each of the images is detected, an area enclosing a detected human face is set as a focus evaluation area, and a focus evaluation value is calculated. Once focus evaluation values for all the images taken have been calculated, the image with the highest focus evaluation value among the images is chosen and recorded. Thus, an image in which the human face is in focus can be readily taken without having to perform cumbersome operations such as an image choosing operation.

An adaptive scanning optical microscope has a scanner lens assembly for acquiring images from different parts of an object plane and for forming a preferably curved image field having at least some aberration which varies as a function of the part of the object plane from which the image is acquired. A steering mirror selects the field of view and steers light from the object and along a light path from the object plane to a final image plane. An adaptive optics element receives the steered light from the object and compensates for the field position dependent optical aberrations and additional optics are along at least part of the light path for conditioning and focusing the light as it moves from the steering mirror, past the adaptive optics element and to the final image plane.

MRI operates by passing current through gradient coils to create a magnetic field. Creation of the magnetic field requires a relatively high current which causes a large heat build up within the MRI, especially in the patient space. The present invention provides for a hollow conductor through which a coolant can be passed directly during the application of current.
