During the meeting session, the smart board camera can deliver unprecedented clarity, even after zooming in on the speaker. 12MP provides enough space for image compression with higher signal-to-noise ratio. While we have a Full HD video conference, the image sensor would calculate based on the light information collected in more than 4 pixels to form a single pixel. Therefore, the proportion of electrical noise in the circuit would be greatly reduced, increasing the clarity and saturation of the image.
