If you have a picture in 120 megapixel resolution and open it in Image View app, then zoom it to 100%, you will need a week to scroll it up and down on your regular LDC monitor 🙂
Canon announced that have developed an APS-H-size(29.2 x 20.2 mm) CMOS image sensor capable of recording 120 megapixel images (13,280 x 9,184 pixels)- the world’s highest level of resolution for its size. The new sensor has pixel count nearly 7.5 times larger and offers a 2.4-fold improvement in resolution, than their commercial available CMOS sensor of the same size. It also offers a Full HD (1,920 x 1,080 pixels) video output capability and makes possible a maximum output speed of approximately 9.5 frames per second, supporting the continuous shooting of ultra-high-resolution images. The sensor can output Full HD video from any approximately one-sixtieth-sized section of its total surface area.
But for now, Cannon didn’t announce details when the first DSLR with the new sensor will hit the market. I only know that you’ll need to buy a lot of SD cards for every one shot you’ll do 🙂
