Apparatus for improving image quality and method thereof

A method comprising:

• converting image information to one of an unprocessed first image signal and a processed second image signal in accordance with an error value;
• storing one of the converted first image signal and the second image signal;
• analyzing a value of one of the first image signal and the second image signal;
• comparing the analyzed value to a target value;
• calculating an error value if the analyzed value of one of the first image signal and the second image signal fails to match the target value;
• applying the calculated error value to the second image signal;
• and then
• calculating an image quality improving value if the analyzed value of one of the first image signal and the second image signal matches the target value.

An apparatus comprising:

• a digital camera configured to output one of a first image signal non-processed and a second image signal processed by a first control signal by converting image information to digital information, the digital camera including an image sensor configured to convert the image information to the digital information to output the first image signal;
• an image streaming device configured to store one of the first image signal and the second image signal output from the digital camera, the image streaming device also configured to output the first control signal by processing the second control signal the image streaming device including a frame memory configured to store one of the first image signal and the second image signal output from the digital camera;
• and
• a data processor configured to compare a target value to one of the first image signal and the second image signal stored in the image streaming device, the data processor also configured to output the second control signal having an error value in accordance with result of the comparison.
