IPC: H04N5/243
Filed: 1990-05-02
Abstract: PURPOSE:To control a picked-up picture to have a proper exposure and dynamic range by providing an image pickup means, an inverting means inverting the polarity of the output of the image pickup means and a correction means correcting a black reference of the output of the image pickup means attended with the operation of the inverting means so as to implement the exposure control or the like. CONSTITUTION:A clamp level Vref being a black level shift in the negative mode is set as Vref2=Vref1-VEO. Thus, in the relation between an exposure LogH of an output luminance signal from a clamp circuit 14 onto a film and a value equivalent to a luminance signal level, a signal level equivalent to a maximum exposure E0 is obtained from a signal level Ve2 equivalent to a film minimum exposure E2 and a signal level Ve1 equivalent to a film mean exposure E1. A detection circuit 18 uses the output luminance signal of the clamp circuit 14 to apply mean value or peak value detection. Since an exposure controller 20 is driven by the detection output, optimum exposure control is attained.

Title: Protective circuit for cmos ic
Inventor: KAWAI JOJI
IPC: H01L21/8238
Filed: 1988-05-11
Abstract: PURPOSE:To obtain a protector circuit which eliminates a limit resistor from each input terminal of C-MOS IC by connecting a diode between a power terminal and a power line. CONSTITUTION:A protective circuit has a C-MOS IC 1; a resistor 4 and a capacitor 5 which constitutes a differentiating circuit; a diode 3 which clamps an over input voltage to the C-MOS IC 1; and a diode 10. By this means, when a differential input voltage V11 is changed from OV-Vcc, an input voltage to the CMOS IC 1 becomes higher than Vcc. However, due to the diode 10, a current from an input terminal to a power terminal through inside of the IC 1 do not flow. Thus, a current limit resistor is unnecessary to each input terminal and circuit protection against over voltage is obtained.
