Analyzing an object chenge from a moving picture using time series information of changes between images and by extraction of such information

摘要

An object of the present invention is to construct a sensing system capable of extracting change information as new time series information from a continuous moving picture in a non-contact manner and remotely without requiring a special illuminating and irradiating device and driving the succeeding processing system as required, to clearly show a phenomenon in an arbitrary frequency band existing in the moving picture. The present invention provides an apparatus for and a method of extracting time series image information, which comprises input means for inputting a moving picture of an object, primary processing means for detecting a primary information change in each of corresponding regions of a frame at a time point T0 which is updated and a frame at a time point T1 which is updated in a predetermined relationship with the time point T0 with respect to natural time series information on the moving picture inputted at a predetermined frame rate, secondary processing means for newly arranging the primary information change as an element to create a time-series-signalized primary information change which is arbitrary time series information and extracting a time-series-signalized secondary information change having a physical meaning different from that of the time-series-signalized primary information change as required.
