Definitions

• Figure 5 shows a fifth view of the user interface at the third point in time which highlights the ability to add and show additional operators and/or filters in other operator bars;
• Figure 6 shows a sixth view of the user interface at the first point in time which highlights the ability to change exposure and contrast levels;
• Exposure is changed for a given region by moving the top slider of the given region.
• Contrast is changed for a given region by moving the bottom slider of the given region in the all-regions control section 34. Comparing to Figure 1 , only the exposure and contrast for region 10 are changed. Note that the exposure and contrast levels are set for each operator separately in this implementation. This means that the exposure and contrast levels will remain the same for the entire set of frames that is operated on by an operator. Of course, the regions are expected to change from frame to frame, depending on the pixel intensity values, but the exposure and contrast settings remain the same.
• anchor points it is also possible to add or delete anchor points.
• the advantages will typically be similar to changing anchor points. For instance, sometimes a user can add more anchor points in order to have finer control over the tone mapped image.
• the upper bars and lower bars will change the exposure and contrast parameter for each region, defined by the weight images. From the end user's viewpoint, upper bars change brightness and lower bars change contrast.
• two extra global parameters i.e. all-regions control section 34
• Moving the global exposure bar will change the exposure parameters for all regions and moving the global contrast bar will change the contrast parameters for all regions.
• These two global bars can be used in situations, for example, in which the end user would like to change the global brightness or contrast. For instance, if the user finds out that the tone mapped picture is too bright, the user does not need to decrease the exposure parameter for each region separately. Instead, the user can move the global exposure bar to the left, which will result in moving of all upper (exposure) bars to the left for each region simultaneously.
• a device such as for example, a pre-processor, an encoder, a transmitter, a receiver, a decoder, a post-processor, a set-top box, a cell-phone, a laptop or other personal computer, a PDA, or other consumer communications equipment, containing a processing device of Implementation 8.
