Claim 5:
6. A method for capturing an inspection image of a board on which multiple components are disposed with a fixed focus type camera, the method comprising:
acquiring height information of the multiple components, the height information stored in a management device and based on mounting schedule information of the board;
setting a reference position separated from a top surface of the board by a distance corresponding to a height of each of the components, acquired from the height information, according to a predetermined setting method such that an imaging surface of each component within an imaging range of the camera is included in a depth of field of the camera the predetermined setting method using a most frequent value of the heights of the respective components as the distance, and in a case where there are multiple most frequent values when using the method of setting the reference position by using the most frequent value as the predetermined setting method, multiple reference positions are set by using each of the multiple most frequent values;
moving the camera up or down relative to the board such that the camera focuses on the reference position, and then capturing the inspection image; and
controlling the camera such that the inspection image is captured at each of the multiple reference positions.
