Abstract
To provide a displacement sensor device capable of fast data read-out processing. A sensor device includes: a light-emitting element for irradiating an object to be measured with light at a prescribed angle; an image pickup element for shooting the light-irradiated object to be measured at another angle; a normal measurement area setting device capable of setting a normal measurement area in the visual field of the image pickup element; a receiving-light signal detecting device for detecting a receiving-light signal distribution area of the object to be measured from the set normal measurement area; a following-type measurement area setting device for setting at least one following-type measurement area which includes the detected receiving-light signal distribution area and is narrower than the normal measurement area; a displacement measuring device for measuring a target displacement by measuring the following-type measurement area; and an output device for outputting the measured displacement.
