  • Ultrasonic imaging system and display device
    Publication number: 20030040673
    Abstract: To make it possible to lower the luminance of an LCD to a level suitable for a dark place, either first image data based on which a predetermined image is displayed or second image data based on which the same image is displayed with lower luminance than the predetermined image based on the first image data is transferred to an LCD via a selecting means.
    Type: Application

  • Ultrasonic diagnostic apparatus
    Patent number: 5495846
    Abstract: An object of the present invention is to provide an ultrasonic diagnostic apparatus, which detects a moving part and a stationary part within the same frame and selects a suitable arithmetic averaging coefficient for each of them and thereby keeps well its characteristic to follow up an image and maintains its capability to reduce noises sufficiently. The invention attaining the above mentioned object is characterized by that it comprises:a frame memory for storing old data which are signals received on a previous occasion;a weighting function generator obtaining, for each pixel, differential data as the absolute value of the difference between new data, which are signals currently input thereto, and old data read from the frame memory for calculating arithmetic-averaging coefficients ".omega." and "1-.omega." as weighting functions, which are functions of the new data or the old data and the differential data;a new data multiplier for multiplying, for each pixel, the new data by the data "1-.omega.
