Abstract
A self-diagnostic camera is disclosed which checks the state of each of components operating to take a picture and, upon detecting the occurrence of an abnormal operation, stops the camera operation, reads a corresponding error code from an error code storage unit, and adds the error code to an error history storage unit through an add and update unit. When the storage capacity of the error history storage unit is reached, error codes already stored are transferred to the memory in the add and update unit. Address shift is then made to remove the least recently stored error code and add the most recent error code to the end. The updated error codes in the memory are written again into the error history storage unit. The error codes are read to outside as required.
