Abstract: An electronic apparatus incorporating a microcomputer capable of correcting bugs by means of patches. The microcomputer circumvents serious trouble which would usually be produced due to bugs when the power supply is turned on. After the power supply is turned on and initialization of the microcomputer itself is complete, it is determined whether the initialization processing for correcting by patches has ended. If this processing has not yet ended, the microcomputer is inhibited from controlling certain objects (e.g., circuits for driving motors that control the tape transport mechanism of a video camera) which would cause serious trouble if they were to malfunction. The microcomputer control of other objects is not so inhibited. After the end of the initialization for correcting by patches, a program capable of correcting by patches is executed.
