摘要
Disclosed is a nail region detection device including: colour camera; image data storage part; colour specification conversion plotting part for converting captured image data from the RGB colour specification system to the HLS colour specification system; a-threshold value setting part for setting and varying a threshold value along the X axis with respect to a first plotting region; second plotting part for replotting in a two-dimensional planar second graph, plotting data items which are equal to or greater than the threshold value and detecting the physical quantity or its ratio in a plurality of second plotting regions in the second graphregion; repeat control part for repeating the processing for replotting the data items; nail determination part for determining, as a nail region, a second plotting region in which the gradient of the amount of variation in the physical quantity or its ratio is equal to or less than a predetermined value.
