So before you choose the Side by Side (Full) as the output 3D mode, you should check whether the device supports the output video resolution first. If you choose the Side by Side (Full), the output video frame for the left/right eye will be at a 1280*720 resolution, which means the resolution of the output video will be 2560*720. If you choose the Side by Side (Half-width), the output video frame for the left/right eye will be at a 640*720 resolution, and the resolution of the output video will be 1280*720.
Let's take a 720p (resolution of 1280*720) source video as an example to see the difference between Side by Side (Half-width) and Side by Side (Full) It then displays these upscaled individual frames alternately in a frame-sequential manner.
When TV receives this 3D Side by Side signal, it splits each frame to extract the frame for each eye, and then rescales these individual frames to a full HD resolution using upscaling algorithms.
In 3D Side by Side, one frame consists of two halves on the left and right, with the entire frame for the left eye scaled down horizontally to fit the left-half of the frame, and the entire frame for the right eye scaled down horizontally to fit the right side of the frame.
And you can play the 3D video on common TV, computer monitors, and even the common portable devices.
To watch the Anaglyph 3D video, what you need is just a pair of archetypical 3D glasses. Glasses with colored filters in each eye separate the appropriate images by canceling the filter color out and rendering the complementary color black." In a subtractive light setting, the two images are printed in the same complementary colors on white paper. Anaglyph 3D is the earliest method to present theatrical 3D, as it requires less specialized hardware.Īccording to Wikipedia, "In an anaglyph, the two images are superimposed in an additive light setting through two filters, one red and one cyan. Among these 3D image flavors, red/cyan is the most popular one. AnaglyphĪnaglyph refers to color filtered 3D pictures including amber/blue, red/green, red/blue and red/cyan. General 3D Movies ModesĬommon 3D film modes include Anaglyph and Split Screen. We call this principal "Polarizing Theory".Īccording to this principal, if we make two separate images of a same picture from two eyes' visual angle difference, and show these two separate images simultaneously - one to each eye, we can feel the stereoscopic effect of the image with the help of special projection hardware and/or eyewear like 3D glasses. Although the difference is small, after being transferred to brain via retina, our brain can use this small difference to produce far or near depth thus to produce stereoscopic effect. There are about five centimeters between left eye and right eye and two eyes' visual angle are different when seeing something except when starring at the front. Human visual can tell far or near distance because of the distance between two eyes. What are 3D and 3D Movies?ģD movies mainly make use of human eyes' visual angle difference and convergence to produce stereoscopic effect. It is a concept relative to 2D (something only has width and height).ģD movies refer to the motion pictures adding stereoscopic vision. 3D (three-dimensional) means something that has width, height and depth (length).
