Filed: 1984-02-24
Abstract: PURPOSE:To perform the symmetrical conversion of picture without receiving the effect of an edge angle by giving the nonlinear processing to a notice picture element and changing the level of the notice picture element to a prescribed level. CONSTITUTION:The levels of a notice picture element and its left, upper, right and lower picture elements are referred to as X, A, B, C and D respectively. Then, a function (f) and a difference Dh in horizontal direction of a picture via defined as formulae 1, 2 respectively. In other words, when differences X-A and X-C have the same code, the difference having larger absolute value is defined as an edge. While the sum of both differences is obtained when both differences have different codes. Then an edge area can be separated from a fixed sloping area. In the same way, a differential Dv of the vertical direction is defined by an equation (3) and a composite differential Dc is defined from differentials Dh and Dv and by an equation (4). Thus the constant conversion processing is possible regardless of angles by introducing a non-linear processing into acomposite difference such a way. Then a signal Y is obtained from an equation (5) after a picture element X is converted, where (n) means a coefficient for control of edge detection. Then the contrast can be controlled by varying the (n).

Title: Magnetic display device
Inventor: MITANI SHIGEO
IPC: G09F9/37
Filed: 1989-02-14
Abstract: PURPOSE:To give variation to the attracting state of magnetic particles and to vary the gradations of light and shade of a display image by varying the intensity or application time of a display magnetic field. CONSTITUTION:A microprocessor 8 sends a control signal for raising the voltage of a variable voltage power source 1 to put a column switching circuit 3 and a row switching circuit 5 in operation and a coil 7 is fed with electricity where printing is performed. Then the applied voltage is high, so a current which flows through the coil 7 increases, a produced magnetic field becomes intense, and the number of attracted magnetic particles increases, so that a thick image is displayed. When the control signal is sent so that the voltage of the variable voltage power source 1 falls to the contrary, the current flowing through the coil 7 decreases, the produced magnetic field becomes weak, and the number of attracted magnetic particles decreases, so that a thin image is displayed. Thus, gradations of light and shade of the display image can be varied by varying the intensity of the display magnetic field.
