When using HD video cameras in stores a large storage space is needed. The required

storage space can be decreased using motion and a color detection algorithm that

makes the camera records only when a motion or a lighting change occur. So, in this

work a real time motion and color detection is presented based on the difference of

two successive frames of images after dividing the image into blocks, different block

sizes are tested (2×2, 4×4 , and 8×8).YCbCr color system is used for each case with

different thresholds for Cb, Cr, and Y. Good results for the motion detection can be

obtained using Cb, and Cr other than Y, since the coloring components of an image are

exist in Cr, and Cb, which are important for motion detection. Additionally the

components that produce or reflect bright light can be obtained from Y. Consequently

the result of lightening change detection at different illumination conditions is better

using Y more than Cb, and Cr. This means that the best result for both motion, and

lighting change detection is obtained by combining the chrominance (Cb, Cr) and

luminance (Y) components of a video. The data used in this work are collected in an

indoor environment using a laptop webcam under different illumination conditions.
