Abstract: There is provided a control unit of an optical apparatus and an image pickup apparatus, which can prevent a shift of an already controlled position of a member when an impact, etc. apply to the optical apparatus. A control unit for an optical apparatus that includes a first member that is movable, an actuator, and a drive mechanism that transmits a driving force of the actuator to the first member, includes a determination part for determining whether the optical apparatus or a second member provided to an apparatus attached to the optical apparatus is to move, and a controller for controlling, prior to a movement of the second member, the actuator from a first state at which the drive mechanism can transmit the driving force to a second state at which the drive mechanism cannot transmit the driving force, when the determination part determines that the second member is to move.

Abstract: In a program executing apparatus, a code reading section reads intermediate codes into a storage unit. A data-reference analyzing section determines whether the operands of instructions in the intermediate codes stored in the storage unit require a data reference. Each data reference is analyzed for instructions requiring the data reference. A code rewriting section rewrites the operands of the instructions according to the analysis information obtained by the data-reference analyzing section. An address updating section updates the addresses of address-related instructions. After all intermediate codes are interpreted, a main interpreting and executing section starts interpreting and executing the intermediate codes.
