Method and apparatus for determining flicker in the illumination of a subject

An apparatus for determining flicker in the illumination of a subject, the apparatus comprising:

• an image capture device for capturing a first image frame of said subject and a second image frame of said subject;
• a processing unit adapted to form a third image frame from at least a portion of said first image frame and a corresponding portion of said second image frame, wherein said third image frame comprises reduced subject information relative to the level of flicker;
• and
• a detecting unit adapted to detect a flicker pattern from said third image frame.

A camera operable according to a method of determining flicker in the illumination of a subject, the method comprising the steps of:

• capturing a first image frame of said subject;
• capturing a second image frame of said subject;
• forming a third image frame from at least a portion of said first image frame and a corresponding portion of said second image frame, wherein said third image frame comprises reduced subject information relative to the level of flicker;
• and
• detecting a flicker pattern from said third image frame.
