Abstract: During successive approximation analog to digital conversion a series of successive digital reference values is selected that converges towards a digital representation of an analog input signal. An analog reference signal is generated dependent on the successive digital reference values and compared to the analog input signal. The digital reference values are selected dependent on comparison results. In the selection of the digital reference values successive steps between digital reference values are each selected dependent on values of the comparator result from a plurality of preceding recursion cycles. The comparison results define a series of successively narrower ranges of digital values that contain a digital representation of the analog input signal. Use of a plurality of comparator results for selecting the steps in the digital reference values makes it possible to reduce uncertainty about whether the comparison result has settled.

Abstract: A method of displaying digital samples with enhanced image details on a raster display using a limited set of brightness values is provided. Digital samples are interpolated and stored as pixel information in high resolution intensity memory. An adaptive mapping process maps the high resolution intensity information to low intensity brightness information in a manner so as to maximize image details. An equal number of brightness levels from light to dark are allocated in each column along the sweep. An adaptive recombination process combines past and present brightness information in a manner that best preserves image details when the temporal behavior of the display image is changing. A raster display device is employed to display the image which is stored in the display memory as pixels arranged by row and column.

Abstract: A structure with fine details, such as a periodic signal, is displayed on a raster display. To avoid aliasing due to an interference between the details and the columns and row pattern of the raster display each of the points representing the structure to be displayed is allocated to pixels in adjacent columns and/or rows. Allocation occurs by means of a stochastic procedure in which the probability to allocate a point to a pixel is dependent on the position of the point with respect to the pixel. Accumulated pixel-values are converted into a limited number of grey-values by means of an additional procedure that allows for fixed proportions of the pixels to have the same grey-value.
