| <h4>● Overview</h4> |
| This effect reproduces a camera lens blur. The input image is divided into several layers<br> |
| based on the gradation of the Depth reference image, and the RGB values of each divided<br> |
| layer are converted into exposure values, blurred using the Iris shape, and combined.<br> |
| Higher speed is achieved by using the discrete Fourier transform. Before blurring,<br> |
| a process of extending the parts of each layer that is hidden in the foreground with a<br> |
| Median filter can be performed. |
| |
| <h4>● Input Port</h4> |
| <UL> |
| <LI><b>Iris</b> : Connects the image to define the shape of the Iris. The image luminance values<br> |
| will be used for the effect. If no image is connected to the Iris port, no calculation will<br> |
| take place. It's possible to connect 8bit or 16bit RGBA images. |
| <LI><b>Source</b> : Connect the input image. If nothing is connected to the Source port, no<br> |
| calculation is performed. |
| <LI><b>Depth</b> : Connect the Depth reference image. The brightness of each pixel corresponds<br> |
| to the depth. The higher (brighter) the value, the farther away from the camera. |
| </UL> |
| |
| <h4>● Parameters</h4> |
| <UL> |
| <LI><b>On-Focus Distance</b> : If there's a layer in this position, it will look on focus and it will<br> |
| be composed normally. 0 represents the camera position. (Range 0.0-1.0) |
| <LI><b>Bokeh Amount</b> : Maximum size of blur (in scene units). When the focus position and<br> |
| the layer position are 1.0 away from each other, the Iris image is enlarged until the<br> |
| width of this image reaches this value. |
| <LI><b>Hardness</b> : The gamma value of the film. Used to convert between RGB value and<br> |
| exposure. This is equivalent to the increase in RGB value (0.0 to 1.0) when the exposure<br> |
| is increased 10 times. The lower the value, the more the highlights are emphasized.<br> |
| (Range 0.05-3.0) |
| <LI><b>Distance Precision</b> : The number of divisions of the depth reference image. The larger<br> |
| the value, the finer the gradation of the blur size, but the slower the processing.<br> |
| (Range 3-128) |
| <LI><b>Fill Gap</b> : Specifies whether to extend the further segmented layer pixels in order to fill gap. |
| <LI><b>Use Median Filter</b> : Specifies whether to use median filter for the extension. <br> |
| This option is recommended when the depth is distributed discretely. |
| </UL> |

| <h4>● Notes</h4> |
| <UL> |
| <LI>When rendering multiple frames, the Iris and the layers images, must be present within<br> |
| the range of all frames to be rendered. |
| <LI>This effect uses a lot of RAM. |
| </UL> |
| |
| <h4>● License Information</h4> |
| <UL> |
| <LI>This effect uses an open source library called Kiss FFT for the Fourier transform.<br> |
