IPC: G06T9/00
Filed: 1990-03-16
Abstract: PURPOSE:To reduce a data quantity of a 2-dimension scalar data by utilizing Laplacian as to a given 2-dimension scalar data to send the data and applying interpolation processing depending on the relation of a function provided with the Laplacian. CONSTITUTION:An edge detection section 1 uses a brightness and a chromaticity of a picture to detect a border on a picture. An area division segmentation section 2 segments an area on a horizontal scanning line based on information relating to the detected edge. A phi extraction processing section 3 obtains a Laplacian  phi corresponding to a scalar data phi in a segmented area. An information compression processing section 4 extracts a function f(i) representing the Laplacian  phi and a value phi(i, j) as to a minority value in the area to compress the information. An interpolation processing section 5 obtains a value phi(i, j) at each point on each horizontal scanning line based on the result of compressed information through interpolation to reconstitute the original 2-dimension scalar data. Thus, the data quantity is reduced.

Thus the error signals are emitted and received at table 27 to index ΔVF/ΔIP corresponding to the voltage and the current of tube 8 then, with multiplication by the error signal to be memorized 28. Then D/A conversion 29 is given to the memory contents for correction toward reduction of the error via DC stabilization power source 19. The memory contents is then applied to the filament via inverter 20 and transformer 11. As a result, the filament current flows to obtain the prescribed tube current to be controlled to hold the set value even with the up-down change of the tube voltage. At exposure of the X-rays, stored memory 28 is drawn out and undergoes D/A conversion 29 to control the output of filament  stabilization current 19. Thus, the filament voltage features another new value.
