Technology
Method and System for Reducing Noise in a Digital Image and Apparatus Thereof
IP Status
USP 7,324,143
Technology Description
All solid-state detectors are subject to thermal noise that degrades the resulting images. RIT has a patent-pending technology that effectively reduces apparent noise in images made with digital cameras. This noise-masking filter recognizes that noise contributions to images from digital cameras vary with the specific set of pixels in the imaging array. A two-step process is used to greatly reduce the noise while preserving image quality. Advantages of this technology are dramatic noise reduction with minimal artifacts, perceived image quality preserved even at exposure duractions 5 stops longer than recommended for high-end digital cameras, can work with or in place of current noise filters, and that it works with all digital cameras.

Measuring a Lighting Condition and a Method Thereof
IP Status
USP 6,577,395
Technology Description
Accurate color prediction requires information about lighting conditions. Typically this is obtained through use of expensive measuring instruments. The RIT methodology allows one to measure lighting conditions by using a characterized display, reflecting objects and human visual ability. This is a low-cost, simple-to-use methodology with superior results.

Technology
Color Correction & Spectral Estimation Using Multi-Illuminant or Multi-Filter Trichromatic Image Capture
IP Status
Patent pending
Technology Description
The color of images reproduced with photographic cameras and color film or with digital color cameras may not accurately match the colors of the original scene or object. RIT has a methodology to achieve excellent color match under all types of illumination. The problem of metamerism is resolved by using inexpensive tri-chromatic filters in conjunction with computers and color-temperature-controlled illumination. The result is faster image reproduction with faithful color reproduction achieved at lower cost and without the use of inference filters. Applications include professional photography, catalog printing, sales brochures, and control of die mixtures.

Technology
System and Method for Analyzing, Optimizing and/or Designing Spectral Sensitivity Curves for an Imaging Device
IP Status
USP 7,173,657
Technology Description
A system and method for optimizing a set of filters to ensure close reproduction of original colors has been developed. Using metrics to predict the image quality and/or noise sensitivity of the performance of a set of filters means that systems may be designed and compared without the need to build prototypes.

Technology
A Data-Efficient and Self-Adapting Imaging Spectrometry Method and Apparatus Thereof
IP Status
USP 6,920,244
Technology Description
This technology is an extension of 00-04. To achieve faithful rendition of the spectra of colors in a scene or of an object, an optimum set of filters is automatically selected using this technology. This is a substantial improvement over other methods which select three color filters (RGB) with fixed spectral characteristics.

A Method and System for Optimizing the Selection of Camera Spectral Sensitivities
IP Status
USP 7,326,195
Technology Description
This technology is an extension of 00-04 and 00-10. This hierarchical approach is used in developing imaging products to obtain a selected set of filters that best satisfies the RMS criterion. Metrics are arranged in order of importance for faithful color reproduction.

RIT IMPO Number

Technology
Color Profiling Based on Image Quality Criteria
IP Status
Patent Pending
Technology Description
Because the human visual system integrates incident light, different colorant combinations and amounts can result in the identical perceived color. This is known as metamerism. This results in a one-to-many mapping problem in which there are multiple solutions to achieving a specific color value. As the number of colorants increases, the mapping problem becomes more difficult. In this invention all possible colorant combinations are determined that can achieve a specific input value. Thus this method solves the one-to-many mapping problem. The methodology has been successfully demonstrated with six-ink printing but it is applicable to any number of colorants. This invention can be applied in printing, both desktop and on press, when needing to convert from a color specification to colorant amounts.

Technology
A Scheme for Compressing Digital Halftoned Images
IP Status
USP 7,245,778
Technology Description
A novel method to losslessly compress halftone images for storage and communication has been developed. With this algorithm grayscale images are converted to binary. The conversion process allows one to sort the pixels of the halftoned image into a form for which the first-order entropy is quite small. Thus the transformed image can be easily compressed by standard techniques. The resulting compressed file can also be readily uncompressed. The compression-decompression routine could be built into the data path for a printer to allow faster communication from the host computer. A 5-10 factor file size compression ratio is achieved; i.e. the compressed file size is 10-20% that of the uncompressed filed.
