Title: Driving device for image pickup element
Inventor: TANI NOBUHIRO
IPC: H04N5/378
Filed: 1988-12-21
Abstract: PURPOSE:To eliminate the difference of smear levels in a movie mode and a still mode by outputting a sweeping-out signal from a pulse signal output means at every field when a sweep-out requesting means is turned on. CONSTITUTION:To an image pickup means 11, a periodical accumulation control means and reading signal are periodically outputted from a pulse signal output means 13 at a normal time and a signal charge is transferred from a vertical transferring part at usual speed. On the other hand, at the time of electronic shutter operation, a forcible accumulation control signal is outputted from a control means 14 to the image pickup means 11 and a sweep-out requesting signal is outputted to the pulse signal output means 13. Then, the unnecessary charge of a light receiving part is transferred to the vertical transferring part and swept out in a short time. At the time of the movie mode, when a sweep-out requesting signal output means 25 is operated, a sweep-out signal is outputted from the pulse signal output means 13 at every field and the unnecessary charge remaining in the vertical transferring part is swept out in a short time. Thus, the smear level is made uniform in the movie mode and still mode.

Title: Sense circuit
Inventor: MUTO SHINICHIRO
IPC: G11C11/419
Filed: 1991-12-06
Abstract: PURPOSE:To prevent the flowing of a steady-state current after an input potential changes and thereby to reduce power consumption by a method wherein MOSFET for current control of which the conductivity type is different from a load is inserted in series to the load. CONSTITUTION:When potential V1 and V2 of input terminals T1 and T2 are high, resistances of nMOSFETs M2, M4 and M6 are low and, therefore, the resistances of pMOSFETs M1 and M3 lower as well. Consequently, a steady- state current flows through Path 1 and Path 2. When the potential V2 of the terminal T2 turns low, the FET M4 is put in an OFF state and no current flows through the Path 2. Since the resistance of the FET M4 becomes high, moreover, no current flows either through the Path 1. When the potentials V1 and V2 are low, the resistances of the FETs M2, M4 and M6 are high and no steady-state current flows through the Paths 1 and 2. Although the resistance of the FET M2 turns low when the potential V1 becomes high, the resistance of the FET M6 remains high and no current flows through neither of the Paths 1 and 2.
