Correlation test between digital camera parameters and visual noises

Noise and unwanted signals as a response of an imaging process is an important factor in digital imaging systems. The standardization of noise measurement in determining the quality of digital imaging is in International Standard of Organization (ISO15739:2005). Since the amount of noise may vary significantly with exposure time and ISOs, the visibility of noise to human observers depends on the viewing distance, spatial frequency, density, color, and viewing condition. This concept is applied to this study, which is called dasiavisual noise,psila and it is measured by digital camera parameters such as ISOs and shutter speed variables applying the noise reduction option on and off. In this study, we will present the practical digital camera parameter for minimizing visual noise to consumers and expect efficiency of noise reduction from digital camera manufacturers. Furthermore, we can expect the following study to measure the human spatial response related to visual noise recognition.
