A recording apparatus includes: a recording head that performs recording on a recording target medium; a driving mechanism that is capable of causing the recording head to move closer to the recording target medium or move away from the recording target medium; and a controlling section that determines driving amount for one driving operation that is performed by the driving mechanism on the basis of results of a comparison made between a first recording head movement direction that is taken or to be taken in the one driving operation and a second recording head movement direction that was taken in another driving operation that is immediately before the one driving operation and thus precedes the one driving operation.

An image processing device comprising: a determination section that, based on a factor defining a depth representing a permissible range for acceptable state of focus and on parallax computed by a parallax computation section, determines an operation movement ratio for converting an operation amount, that instructs movement of a focusing lens, into a movement amount of the focusing lens by using a function including the operation movement ratio as a dependent variable and an independent variable determined according to the factor and the parallax; and a control section that controls a movement section to move the focusing lens by an amount equivalent to a movement amount determined based on an operation movement ratio determined by the determination section and the operation amount.

A CCD image sensor is fixed on a Y-direction stage that is supported on an X-direction stage. When a piezo driver supplies voltage to an X-direction piezo element and a Y-direction piezo element, the CCD image sensor is moved in X and Y directions. The X-direction position sensor and the Y-direction position sensor detects the position information of the CCD image sensor in X and Y direction respectively, and send the position information to the piezo driver. The piezo driver sets a target movement of the CCD image sensor, and detects the actual movement of the CCD image sensor from the position information. The piezo driver adjusts the output voltage to the X-direction piezo element and the Y-direction piezo element such that the target movement becomes the same as the actual movement.
