Claim 10:
11. An apparatus for detecting surface characteristics on incoming food objects, comprising:
a first imaging device for capturing two-dimensional image data and a second imaging device for capturing three-dimensional image data of a food object;
at least one image processing unit configured to:
utilize either one of said 2D or said 3D image data in determining whether a potential defect is present on the surface of said incoming food object, where, in case such a potential defect property is detected, determining a surface position of said potential defect;
utilize the remaining one of said 2D or said 3D image data in determining whether an actual defect is present on the surface of said incoming food object at said determined surface position; and
in case the potential defect property is detected and no actual defect is present, indicate a false-positive result of the actual defect obtained from the 2D image data, the false-positive result being defined as a wrong indication of the actual defect on the surface of said incoming food object;

an output unit for outputting defect related data in case both of said 2D and said 3D image data indicate that an actual defect is present on the surface of said incoming food object at said determined surface position;
wherein the first imaging device is arranged to acquire the two-dimensional image data before the second imaging device acquires the three-dimensional image data;
wherein the second imaging device is arranged to acquire the three-dimensional image data before the first imaging device acquires the two-dimensional image data.
