Title: Method and device for processing energy subtraction
Inventor: TAKEO HIDEYA
IPC: G01N23/04
Filed: 1995-04-20
Abstract: PURPOSE: To obtain a subtraction image with high image quality by reducing the effect of beam hardening sufficiently even when a degree of the beam hardening differs from each part of an object and reducing the production of an artifact even in the edge where density changes steeply. CONSTITUTION: Two image signals Dorg(1), Dorg(2) with a different energy state are read out of an internal memory, an unsharpened mask signal calculation means 31 calculates a mean image signal Dmean between the two image signals Dorg(1), Dorg(2), and an unsharpened mask signal Lu is calculated on an image signal by using an unsharpened mask of a rectangle longitudinally long and having a short side in a direction crossing the edge of the image. Since the mask signal Lu is based on the unsharpened mask having a short side in a direction crossing the edge, the device easily follows a steep density change in the edge and the production of an artifact in the edge is suppressed by setting a subtraction parameter on the mask signal Lu.

Title: Nonlinear preemphasizing circuit
Inventor: IDETA HIROSHI
IPC: H03G7/00
Filed: 1982-06-01
Abstract: PURPOSE:To obtain an output signal after accurate nonlinear preemphasis processing regardless of the amplitude of an input signal by emphasizing the high frequency component of the input signal. CONSTITUTION:A signal inputted to an input terminal 11 is applied to the base of a transistor (TR)12 and its high frequency component is emitter-peaked by a capacitor 17 and resistors 16 and 15 to obtain an output at the collector side of the TR12. When the values of a resistor 20 and current sources 21 and 22 are selected adequately so that when said input signal is not applied, the collector potential of the TR12 is equal to the emitter potential of a TR19, the high frequency component of said input signal after the emitter peaking of the TR12 is amplitude-limited by the two-way clipping circuit consisting of diodes 23 and 24. The amplitude-limited high frequency component of said input signal is applied to the base of a TR and mixed with said input signal applied to the base of a TR25 at a mixing ratio determined by resistors 26 and 27 and the extent of the emitter peaking, obtaining an output signal at an output terminal 19. Namely, the emitter potential of the TR19 is made constant and only the high frequency component of said input signal appears at the collector side of the TR12. Therefore, a sufficient dynamic range to an input signal which contains a high frequency component superposed on a large-amplitude low frequency component is obtained. This circuit is IC-implemented suitably.

Filed: 1979-07-26
Abstract: PURPOSE:To make superimposition display easy to see by limiting a display level by providing a display level control metnod for a superimposition display screen part. CONSTITUTION:Peak detecting circuit 70 receives clamp videlo signal S2 output from a character receiving circuit and then outputs peak detection signal S5 with its high frequency component eliminated by erasure characteristics selected at need. Mixing circuit 71 subtracts the level of signal S5 from that of video output signal S1 in the high-level period of video gate signal S3 and further adds character pattern signal S4 to the difference signal, thereby outputting picture signal S6 including the obtained sum signal S4. Namely, this output signal is held at a level without subtraction in the low-level period of signal S3 and reduced in level to half in the high-level period of signal S3, and signal S4 is superposed upon it to obtain the picture signal. This signal S6 is mixed with a chroma signal to obtain a video signal, which has  been superimposed on the basis of the character signal, on CRT.
