To easily judge what zoom speed level a device acts at by providing an operation lever for inputting a zoom control command in a zoom means and a setting means for setting the variable speed level of image pickup magnification.

This device is provided with the operation lever 13 capable of changing zoom speed by changing a resistance value according to the moving amount of the lever. A zoom speed setting switch group 12 is a switch group for setting the zoom speed in accordance with the moving amount of the lever 13. By detecting the potential change of a variable resistor due to the movement of the lever 13, a microcomputer 1 judges to what position the lever 13 is moved corresponding to a table previously stored in an RAM 15 based on the detected potential. Furthermore, the microcomputer 1 decides the zoom speed corresponding to the judged position of the lever 13. Then, the decided zoom speed level is displayed to execute zoom control according to the zoom speed level.
