PROBLEM TO BE SOLVED: To improve the responsibility for operations and the productivity of programs of a camera employing a microprocessor that controls a running state of the programs using a real time OS. SOLUTION: The tasks of the camera includes a task 1 carrying out the control using a switch operation, a task 2 supplying/moving a film and a task 3 carrying out the calculation for detecting a focus point. The execution priority of the task carrying out a process with high responsibility for the actual time is set higher than that of the task carrying out a process with low responsibility for the actual time, i.e., the highest priority is set to the task 1, and next priority is set to the task 2, and the lowest priority is set to the task 3. |
