An image stabilization actuator is used to displace a movable unit in a first direction, and a position in the first direction when an AF-axis position detection signal reaches a peak value is detected. Similarly, the image stabilization actuator is used to displace the movable unit in a second direction, and a position in the second direction when the AF-axis position detection signal reaches a peak value is detected. A reference position based on the position in the first direction and the position in the second direction thus obtained is stored. Correction information indicating a relationship between a displacement amount, from the reference position, of the movable unit displaced by the image stabilization actuator and a correction amount of the position detection signal is stored.

A display control device uses frame rate control, and converts m-bit input data (m is an integer) representing brightness of each pixel, to n-bit output data (n is an integer, n&#x3c;m), to control brightness of each pixel. A first frame rate controller generates a plurality of first tone data according to the input data, and outputs the generated data in a time division manner for each predetermined first timing. A second frame rate controller generates a plurality of second tone data according to the input data, and outputs the generated data in a time division manner for each predetermined first timing. Rate of change of brightness represented by the first tone data with respect to the input data, and rate of change of brightness represented by the second tone data with respect to the input data are made different.
