OBJECTIVE IMAGE QUALITY TESTING SYSTEM OF DIGITAL IMAGE MEDIA, CAPABLE OF TESTING THE IMAGE QUALITY OF A SOURCE IMAGE AT A RECEIVING END BY INSERTING A TEST SIGNAL INTO AN IMAGE SIGNAL FOR TRANSMITTING AND A DEVICE THEREOF

摘要

PURPOSE: An objective image quality testing system of digital image media and a device thereof are provided to test image quality without being affected by existing broadcasts while broadcasting by inserting and transmitting a test signal into the transient effect area (TEA) of a source image and detecting and analyzing a test signal from images received and recovered.;CONSTITUTION: A test signal generating part (202) tests the quality of an image. A signal inserting part (206) inserts the test signal into the predetermined domain of the TEA at each frame of a source image. A time code inserting part (204) adds a time code including the frame identification information to the generated test signal. An image quality testing device (30) detects and analyzes the test signal from a decoded image signal for testing and outputting the quality of the image.;COPYRIGHT KIPO 2013;[Reference numerals] (202) Test signal generating part; (204) Time code inserting part; (330) Test signal output unit; (340) First image quality measuring unit; (342) Second image quality measuring unit
