像素点以毫米为单位，表示屏幕上相同颜色的磷光点之间的对角线距离。

Dot is measured in millimeters (mm), and indicates the diagonal distance between same-colored phosphor dots on the screen.

在那个距离下，若观看者想看清楚，一个1080p的HD TV电视机(1920像素宽，高1,080像素的屏幕)每个荧幕细节，需要最少69英寸跨对角线。

At that distance, a 1080p HDTV set (with a screen 1, 920 pixels wide and 1, 080 pixels high) needs to be at least 69-inch across a diagonal if viewers are to see all the detail it offers.

该原理将CMOS图像器件获得的分别在横向、纵向和对角线方向存在半个像素错位的四幅图像用软件合成一幅高分辨率图像。

The principle composes four CMOS images taken staggeringly in half pixel offset in directions of horizontal, vertical and diagonal into a new reconstructed high resolution image.
