Title: Color solid-state image pickup element
Inventor: KAWAJIRI KAZUHIRO
IPC: H04N5/355
Filed: 1987-12-09
Abstract: PURPOSE:To simplify an external signal processing circuit by setting a charge storage time of each color different depending on a color temperature so as to obtain an output signal with white balance. CONSTITUTION:Each polysilicon electrode scanned by a 2nd drive signal is driven so as to give a different phase difference from the 1st drive signal, that is, different shutter time in response to the color temperature. That is, when the color temperature is high, a shutter time tR of a color R is set longer than that of colors B, G, a transfer gate pulse PG is applied and the stored charge is subjected to field shift. On the other hand, when the color temperature is low, a shutter time of a color G is set longer than that of color R and a shutter time of a color B is set longer than that of color G and a stored charge is subjected to field shift. Then the stored charge sent to a horizontal transfer line 3 is read out of a buffer amplifier 4 during the horizontal readout period. Thus, the apparent color balance is taken and an output whose dynamic range is expanded is obtained.

IPC: G01R19/00
Filed: 1989-11-30
Abstract: PURPOSE:To certainly detect the change of signal to be measured by turning the light incident to an optical probe ON/OFF by a light chopping means. CONSTITUTION:The polarization state of light in an optical probe 34 changes corresponding to the electric field due to the voltage of an electronic device 46 to be measured. Incident light is reflected by a light reflecting surface 34A in the optical probe 34 to reach a polarized light beam splitter 54 to be reflected toward the first photodetector 38. The primary light from an ultrasonic light modulator 36A passes through a beam splitter 56 and a part thereof is reflected at this time and reaches the second photodetector 40. The output of a lockin amplifier 42, that is (output A of photodetector 38-output B of photodetector 40)=C is inputted to a recording apparatus 55 to be displayed and analyzed by a display and analyzing apparatus 57. The correction circuit 44 provided on the output side of the amplifier 42C operates the difference between the output of the amplifier 42C in such a state that no electric field is applied to the probe 34 and the output thereof in an applied state and divides the output difference by the output of the photodetector 38 in such a state that no electric field is applied to the probe 34. As a result, the distortion of a signal waveform based on the ON/OFF in the device is eliminated.
