摘要： A computer program product for converting from a first floating point format to a second floating point format, each floating point format having an associated base value and being represented by a significand value and a exponent value, comprising an executable algorithm to perform the steps of: determining the second exponent value by multiplying the first exponent value by a predefined constant and taking the integer portion of the result, the predefined constant being substantially equivalent to the logarithm of the first base value divided by the logarithm of the second base value; determining a bias value substantially equivalent to the second base value raised to the second exponent value divided by the first base value raised to the first exponent value; and determining the second significand value by multiplying the first significand value by the bias value.

摘要： An image sensor includes multiple photoactive pixels and multiple dark reference pixels arranged in rows and columns to form a pixel array. A dark signal is read out of one or more dark reference pixels in each column and used to determine a column offset for one or more columns in the pixel array. An offset window is used for each column in the pixel array to define an acceptable maximum dark signal and an acceptable minimum dark signal for each column. The dark signals from each column are analyzed to determine if there are any dark signals outside the offset window. If any of the dark signals are outside the offset window, the dark signal or signals can be compensated for or discarded.

摘要： A method of, and apparatus for, identifying human tissue which is suspected of being physiologically changed as a result of commencement of neoplastic activity or pre-activity, is disclosed. The tissue is preferably irradiated with light at wavelengths of 660 nm and 940 nm. The magnitudes of the reflected, or non-absorbed, light at the two wavelengths is compared, preferably after being normalized by the magnitude of ambient light reflected from the tissue immediately prior to each measurement. The invention finds application in detecting cervical lesions but is also applicable to endoscope inspectable tissues such as the lungs and alimentary canal tissues.

摘要： A method for determining a blended color transform for use in producing printed colors on a color printer having at least four device color channels, comprising: forming first and second color transforms, wherein the first color transform produces printed colors that have a reduced sensitivity to color printer process variations in at least a first region of color space that includes a near-neutral color region, and wherein the second color transform produces printed colors that have a reduced image noise visibility in at least a second region of color space; defining a blending function which computes weighting values for the first and second color transforms as a function of input color values; and using a processor to determine the blended color transform by blending the first color transform and the second color transform, responsive to the blending function.
