Most of the real world scenes have a very high dynamic range (HDR). Themobile phone cameras and the digital cameras available in markets are limitedin their capability in both the range and spatial resolution. Same argument canbe posed about the limited dynamic range display devices which also differ inthe spatial resolution and aspect ratios.  In this paper, we address the problem of displaying the high contrast lowdynamic range (LDR) image of a HDR scene in a display device which hasdifferent spatial resolution compared to that of the capturing digital camera.The optimal solution proposed in this work can be employed with any camerawhich has the ability to shoot multiple differently exposed images of a scene.Further, the proposed solutions provide the flexibility in the depiction ofentire contrast of the HDR scene as a LDR image with an user specified spatialresolution. This task is achieved through an optimized content awareretargeting framework which preserves salient features along with the algorithmto combine multi-exposure images. We show the proposed approach performsexceedingly well in the generation of high contrast LDR image of varyingspatial resolution compared to an alternate approach.
