Patent ID: 8284257

Claim:
An image pick-up apparatus that generates captured images in series, comprising: a specifying unit adapted to specify a subject included in the captured image; a tracking unit adapted to track the specified subject by extracting a region of the specified subject in the presently generated captured image having high correlation with a region of the specified subject in the precedently generated captured image; a display unit adapted to display the captured image on a screen and display identification information showing that the specified subject is tracked; and a setting unit adapted to set a holding time in which the display of the identification information is held according to a sensitivity of an image sensor of the image pick-up apparatus, wherein said display unit continues to display the identification information when the holding time does not lapse after said tracking unit lost the subject, and eliminates a display of the identification information when the holding time has passed after said tracking unit lost the subject, and wherein said setting unit sets the holding time shorter as the sensitivity of the image sensor is set higher.
