Title: Picture estimate device
Inventor: HASEBE TAKASHI
IPC: H04N1/41
Filed: 1987-03-23
Abstract: PURPOSE:To estimate an excellent intermediate tone picture by preparing plural kinds of the scanning aperture with different open area and selecting a density pattern discriminating circuit and a conditional equation discrimination depending on the spatial frequency component of a picture. CONSTITUTION:Plural kinds of scanning aperture being regions set in calculating an intermediate tone level are prepared, and a scanning aperture larger than the referenced scanning opening is selected in case of the low spatial frequency region, that is, in case of a picture such as gradation picture. In this case, which scanning aperture is to be selected depends on whether or not a conditional equation representing no density change in a region to be discriminated is satisfied by using the conditional equation discrimination circuit 70. Thus, in case of a high spatial frequency region, that is, in case of a picture such as a line picture or character picture, a scanning aperture smaller than the reference scanning aperture is selected. Which scanning aperture is to be selected depends on whether or not a condition representing the absence of the change in the density pattern in the region to be discriminated is satisfied by using the density pattern discrimination circuit 60. Thus, an intermediate tone picture close to an original picture is estimated.

Abstract: PURPOSE:To contrive stabilization of signal current by a method wherein the gate potential of an FET is clamped by a clamping circuit consisting of a diode and a resistor, and a resistor to be used for current limitation is inserted between the source of the FET and a negative power terminal. CONSTITUTION:The gate voltage of an FET 13 is applied through the intermediary of a clamping circuit 52 for the stabilization of a signal current, and the clamping circuit is biased by a constant current source 51. Also, a resistor 54 is connected to the source of the FET 13, and the fluctuation of the signal current caused by the variation in environmental condition and the manufacturing deviation of the FET 13 is suppressed utilizing a current negative feed-back effect. Said clamping circuit is composed of a diode 53. Utilizing the temperature dependency of the above- mentioned diode 53, terminal voltage gradually decreases when the temperature of the diode goes up, the gate potential of the FET 13 comes down with the rise of temperature, and the current. As a result, the temperature dependency of the signal current can be erased by setting the current density of the diode 53 in such a manner that the amount of the above-mentioned current attenuation and the amount of current increased by the temperature dependency of the threshold voltage of the FET 13 will be cancelled each other.
