دراسة الخصائص الاحصائية لكاميرا الهاتف النقال نوع ((Nokia7610 تحت شروط إضاءة مختلفة

Abstract

In the latest decades increase importance of digital image capturing, and increase the communicate the information news especially after large development in computer technology. So, we have been developing a digital camera sensor to get high digital images at low costs. While the different digital camera types are so varying in image capturing quality. This gives different qualities for different conditions. In this study, we analyzed the captured images by cell phone Nokia 7610 camera. Where we captured several images under different lightness conditions, with different resolutions. Then we study the statistical RGB distribution for the homogeneous regions. Then compute the statistical properties for RGB distributions by computing the mean and standard deviation of these distributions. The results shown that the captured image under sunlight give high RGB-means comparing with other lightness conditions, also give low RGB standard deviation for all homogeneous regions. Also, we find the yellow, Green, and Blue targets have only Red histograms for all lightness intensities.
