PURPOSE:To eliminate the influence of the reflection of light, a shadow, etc., due to illumination and peripheral electronic parts and to stabilize recognition by calculating a three primary colors RGB distribution vector possessed by every point and grasping the change of the vector. CONSTITUTION:A one-dimensional RGB data memory 6 stores the respective data of three primary colors obtained by extracting the respective one- dimensional data of the three primary colors to be primary data for an inspection from the above-mentioned RGB picture memory 3 at an extracting part 5 by using the data of a CAD data memory 4. Thereafter, a color distribution vector changing angle calculating part 7 calculates the changing angle of the color distribution vector of the three primary colors RGB vector in each picture element from the data of the one-dimensional RGB data memory 6. In this manner, the misregistration quantity of a chip component is calculated, and the mounted state of the chip component is outputted. Thus, the position of the chip component can be accurately judged. |
