Abstract
The range-finding apparatus includes a light source, an optical receiver, a setting unit, a detector, and a calculation unit. The light source projects light with a first irradiation pattern in a first period and projects light with a second irradiation pattern in a second period. The optical receiver receives light to output a pixel signal. The setting unit sets a reference signal based on the pixel signal in the first period. The detector detects whether or not the pixel signal varies from the reference signal by a first value or more in the second period and outputs a first detection signal indicative of a result obtained by the detection. The calculation unit calculates a distance to a to-be-measured object using the first detection signal.
