please send correct answer for Q6 Question 4In colour vision what is the Purkinje shift (dark adaptation)?O A move in colour sensitivity towards the blue end of the visible spectrum in low light conditionsO The ability to see colours well at nightO A physical shift of the retina to be closer to the lens in low light conditionsO The reason we see red light more intensely at nightQuestion 5The advantage of the YCrCb colour model over the RGB representation is that:O It allows more colours to be representedO It takes up less spaceO It allows animationO It splits intensity from colour informationQuestion 6JPEG makes use of the fact that human vision is very sensitive to small variations in brightness/colour and less sensitive to the strength of high-frequency brightness changes. This means that:O We are good at seeing small colour changes between neighbouring pixelsO We can not see high-frequency changes in the imageO Low frequency changes appear as edges in the imageO High frequency changes appear blurredo o o o

In JPEG image , the magnitudes of the high-frequency components are stored with a lower accuracy…
