U.K.-based Image Metrics plc, a provider of imaging technology, announced Tuesday it has completed a $4.2 million Series A funding round. New investors are Saffron Hill Ventures, MC Capital Europe (a subsidiary of Mitsubishi Corp.) and a technology fund managed by Close Brothers Investment Ltd. The funding follows an oversubscribed interim round of $803,000, which the company raised in February.

Image Metrics will use the new money to further explore commercial opportunities, particularly in the United States, and expand the business in security, medical imaging and media sectors. The company was advised by Gambit Corporate Finance. Berry Smith was the company lawyer.
