Title: Gamma correction circuit
Inventor: NAKATANI AKIRA

Filed: 1991-10-23
Abstract: PURPOSE:To avoid black painting-out even when extremely mixing a high luminance part and a low luminance part like a photographic image in case of backlight so as to surely enable a correction by controlling the diagonal point of a clip circuit having various inclinations by a control means such as a CPU or the like and adding the respective clip characteristics. CONSTITUTION:When there is one clip block 7 at an input terminal 1, a rectangular pulse signal having a negative polarity is turned to the clip characteristics of input and output signals. The inclination of the characteristic becomes the gain =1-Rf/Rk of an adder 8. When black extension changeover switches 16-1 and 16-2 are turned off, for the input/output characteristic of the entire circuit, outputs (a)-(d) of blocks 7-1-7-(n) are added. The gain of the low luminance part is changed by a ratio ¦-Rf/R1¦ between smallest additive resistance 9-1 (R1) and feedback resistance 10 (R1). The switches 16-1 and 16-2 are turned on/off by a CPU 12, the additive resistance is switched, only the gain of the low luminance part is switched so as to be enlarged, the input/output characteristic excepting for the low luminance part is controlled by the CPU 12 so as not to be changed and therefore, a black painting-out phenomenon is improved.

Abstract: PURPOSE:To enable the displacement of a piezoelectric device sample to be measured in a non-contact condition and at a high speed by driving one of an objective lens and the sample in an optical axis direction, and measuring the displacement of the sample due to the expansion or contraction thereof via voltage application. CONSTITUTION:An objective lens 36 is positioned by a lens actuator 70 in an optical axis direction, and a piezoelectric device sample 34 for measurement is driven in the optical axis direction of the objective lens 36 and in a direction orthogonal therewith. Then, a measuring beam is converged upon the sample 34 and reflected light from the surface of the sample 34 is made incidental to a heterodyne interference optical system for monitoring the wave front of the measuring beam. Also, a relative interval between the lens 36 and the surface of the sample 34 is changed to keep the constant wave front of the beam at all times, thereby measuring a change occurring on the sample 34 as a change in the aforesaid relative interval. Namely, when voltage is applied to the sample 34, distortion takes place thereon due to a piezoelectric effect, and the displacement of the sample 34 due to expansion or contraction caused thereby can be measured in a noncontact condition and at a high speed.
