Abstract
An image pick-up apparatus including a CCDgenerating an image signal, a timing generatorgenerating various kinds of timing signals for controlling operation timings of CCD, a V drivergenerating various kinds of driving signals for driving CCU in response to the timing signals, a power supply circuitgenerating a power supply voltage Vapplied to the timing generator and V driver, and a CPUcontrolling an application of the power supply voltage to the timing generatorand V driverand controlling the operation of the timing generator. The CPUhas a first operation mode, in which the timing generator is set into a standby mode such that a leak current from the timing generator to the V driver is avoided when the power supply Voltage is not applied to the V driver, and a second operation mode, in which the timing generator is set into a normal operating condition after the power supply voltage has been applied to the V driver. It is no longer necessary to provide a buffer at an input of the V driver, and the leak current can be effectively avoided without increasing a cost of the apparatus.
