Abstract
In a ranging module, a first calculator calculates a distance from a processed signal corresponding to a current pixel. A determiner determines whether the distance calculated by the first calculator differs from a preset limit distance. A re-extractor is configured to, in response to the determiner determining that the distance differs from the preset limit distance, extract pieces of data of processing sections each corresponding to a sweep time of a transmission wave from a time-series of the processed signals saved in a data storage corresponding from a pixel previous to the current pixel in a scanning direction of a scanner to the current pixel while shifting the processing sections one after the other by a time period shorter than the sweep time. A second calculator calculates the distance from the data of each processing section extracted by the re-extractor.
