  1. 1. I MPLEMENTATION OF STEREOSCOPIC & DUAL VIEW IMAGES ON A MICRO-DISPLAY HDTV Presented By, MAHESH.B.R
  2. 2. <ul><li>INTRODUTION </li></ul><ul><li>HDTV </li></ul><ul><li>Aspect ratio </li></ul><ul><li>Available in 3 types(720P, 1080i, & 1080P) </li></ul><ul><li>How does HDTV give better clarity ? </li></ul><ul><li>More scan lines, more information </li></ul><ul><li>Requirements </li></ul><ul><li>Bandwidth, Receiver Compatibility </li></ul><ul><li>How is it different from conventional TVs ? </li></ul><ul><li>Aspect ratio </li></ul><ul><li>Picture quality </li></ul>
  3. 3. PROGRESSIVE AND INTERLACING SCANNING
  4. 4. DMD-Based Micro-Display HDTV <ul><li>Designed using a ”Spatial Light modulator” called DMD technology. </li></ul><ul><li>This DMD tech has speed advantage. </li></ul><ul><li>In this tech, the typical setup is 720P or 1080P. </li></ul><ul><li>Mirrors are arranged in a Diagonal pattern. </li></ul><ul><li>How the required resolution is obtained? </li></ul><ul><ul><li>The fig shows 1080P </li></ul></ul><ul><ul><li>Image pixel to mirror ratio is 2:1 </li></ul></ul>
  5. 5. Smooth Picture Technology <ul><li>SP displaces mirror array by half a pixel. </li></ul><ul><li>In this approach, ½ of the i/p pixel is written in 1 st spatial position. </li></ul><ul><li>Most importantly, all of these are done at single frame time. </li></ul><ul><li>In SP enabled system, i/p is divided into 2 subframes. </li></ul><ul><li>As an example, for 60 Hz,1080P i/p, each subframe will have 1036800 pixels and the subframe is updated at 120 Hz. </li></ul><ul><li>Original image </li></ul>Implementation of Stereoscopic & Dual View Images on Micro-Display HDTV <ul><ul><li>The fig shows 1080P </li></ul></ul><ul><ul><li>Image pixel to mirror ratio is 1:1 </li></ul></ul>
  6. 6. 3D-View <ul><li>SP technology is the key concept </li></ul><ul><li>Firstly 3D data has to be formatted </li></ul><ul><li>SP algorithm defines time for the left and right images </li></ul><ul><li>Next Shutter glasses are to be synchronized </li></ul><ul><li>Same timing signal </li></ul><ul><li>VESA is used </li></ul><ul><li>Block diagram </li></ul>Implementation of Stereoscopic & Dual View Images on Micro-Display HDTV This fig shows how left and right images are created
  7. 7. <ul><li>The SP algorithm separates the pixels using checker board mask. </li></ul><ul><li>This fig shows how separate images are achieved </li></ul>Implementation of Stereoscopic & Dual View Images on Micro-Display HDTV
  8. 8. ISSUES IN 3D <ul><li>Left and Right data not to be mixed. </li></ul><ul><li>High Extinction Ratio </li></ul><ul><li>Digital input port to get the data. </li></ul>Implementation of Stereoscopic & Dual View Images on a Micro-Display HDTV

  11. 11. LCD Shutter Glasses LCD shutter glasses are glasses used in conjunction with a display screen to create the illusion of a three dimensional image, an example of stereoscopy The glasses are controlled by an infrared, radio frequency, DLP-Link or Bluetooth transmitter that sends timing signal.
