In this process, the luminance of the image is compressed, which can cause the contrast of the image to drop, and accordingly the solid appearance of the image to decrease.</p> <p>In such situations, <strong>KNEE APERTURE</strong> reproduces the sharpness and solid appearance of the image, enhancing only the signals compressed by the KNEE function (Fig. 2). Although this function may seem similar to the <strong>DETAIL</strong> function, the two differ in that DETAIL emphasizes the entire luminance range of the signal, while KNEE APERTURE emphasizes signals only in the highlight areas that were compressed by the KNEE function. </p> <p align="center"><img src="kneeaperture.gif" width="493" height="169"></p> <p>. </p> <p align="right"> </p> </td> <td align="right" valign="top"><img src="../../../_gfx/leiste_r.gif" width="2" height="100%"></td> <td valign="top"><table> <tr> <td width="10" height="0"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="10" height="1"></td> <td width="150"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="150" height="1"></td> </tr> <tr class="subnavigation"> <td rowspan="10" align="right" valign="top"> </td> <td valign="middle" class="navi_2gr"><a href="01.intro-digital-basics.htm"><font color="#FFFFFF">Intro</font></a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2gr"><a href="gamma.htm">Gamma</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="dynamic_range.htm">Dynamic Range</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="blk-gamma.htm"><font color="#CCCCCC">BLK-Gamma</font></a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="y_blk-gamma.htm">Y BLK-Gamma</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="knee.htm">Knee</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="knee-sat.htm">Knee Saturation</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="knee-aperture.htm">Knee Aperture</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="detail.htm">Detail</a></td> </tr> <tr class="subnavigation"> <td valign="middle" class="navi_2we"><a href="crispening.htm">Crispenng</a></td> </tr> <tr class="subnavigation"> <td align="right" valign="top"> </td> <td valign="top" class="navi_2we"><a href="level-depend.htm">Level Depend</a></td> </tr> </table></td> <td align="right" valign="top"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="15" height="1"></td> </tr> <tr> <td> </td> <td> </td> <td class="story"> </td> <td> </td> <td> </td> <td> </td> </tr> </table>   <table width="1080"border="0" cellspacing="0" cellpadding="0"> <tr> <td><img src="../../../_gfx/spacer.gif" width="1" height="1" /></td> <td><img src="../../../_gfx/spacer.gif" width="390" height="1" /></td> <td><img src="../../../_gfx/spacer.gif" width="250" height="1" /></td> <td><img src="../../../_gfx/spacer.gif" width="300" height="1" /></td> <td><img src="../../../_gfx/spacer.gif" width="10" height="1" /></td> </tr> <tr class="siteinfo"> <td height="25"><img src="file:///Systemania/Library/WebServer/Documents/_gfx/spacer.gif" width="10" height="1" /></td> <td valign="middle" align="left"> tomimages:::: <a href="../../../impressum.htm"><font color="#FFFFFF">Impressum</font></a> | <a href="../../../kontakt.htm"><font color="#FFFFFF">Kontakt</font></a> | ©2007 Thomas Bresinsky</td> <td> </td> <td valign="middle" align="right"><a href="http://www.neue-horizonte-film.de"><font color="#FFFFFF">Neue Horizonte Film:::: und Medienproduktion</font></a></td> <td><img src="../../../_gfx/spacer.gif" width="1" height="20" /></td> </tr> </table>  </div>  </div>  </body> </html>
