Embodiments of the invention provide a camera module including a lens barrel part in which a plurality of lenses are stacked, a housing having the lens barrel part disposed therein, and an infrared -cut filter provided in the housing and disposed at a lower portion of the lens barrel part. Each scan includes taking measurements of blood flow in the area of interest substantially simultaneously from different angles. The resulting golf ball has high coefficient of restitution at high and low impact speeds and low compression for controlled greenside play. The first routine can include a \u201cTRANS\u201d procedure, a \u201cMIN\u201d procedure, and checkcell tests.
