The digital image processing apparatus includes a similarity calculation unit that calculates a similarity by varying a location of a template on one frame image. The similarity calculation unit calculates a second direction similarity by fixing a first direction location of the template in a first direction on the one frame image and by varying a second direction location of the template in a second direction which is perpendicular to the first direction, and then calculates a first direction similarity by fixing the second direction location of the template at a location where the second direction similarity is the highest and by varying the first direction location of the template in the first direction on the one frame image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus and method for tracking a location of a target subject","description":"A digital image processing apparatus has a tracking function for tracking a location variation of a set tracking area on a plurality of frame images.
