HLS Add Ino\medskip

\par

\normalsize

Add atmosphere (Noise) using values of the specified channel from reference image.\par

Hue, Lightness, Saturation, and Alpha will change.\\

\par

The cell image tone, Hue, Lightness, Saturation, and Alpha will have added noise,\par

use this to be able to adapt the background picture.\par

When painting with the same image, the noise of each dot will be a single tone.\par

Otherwise, the user can provide a reference image as noise,\par

for calculating the noise component of the image, to determine the atmosphere.

\\

\par

Since the processing for a still image is only two-dimensional, if you have the need\par

for a three-dimensional video, another consideration, processing (?) Is required.\\

\par

The Alpha channel will determine the strength of the effect. Thus,\par

masked edges of Alpha will retain their state if they are smooth.\\

\\

-{-}- \ Inputs \ -{-}-\\

Source\par

Connect the image to process.\\

Noise\par

Connect the image for adding the noise by the HLS value for each Pixel.\\

Reference\par

Connect the reference image to put the strength of the effect into each Pixel.\\

\\

-{-}- \ Settings \ -{-}-\\

From RGBA\par

Specify whether to use the channel for the (Noise) Reference image.\par

Choose from one of the \textquotedbl Red\textquotedbl \ \textquotedbl Green\textquotedbl \ \textquotedbl Blue\textquotedbl \ \textquotedbl Alpha\textquotedbl \ channels.\par

The default value is \textquotedbl Red\textquotedbl .\\

\\

Offset\par

The offset value for the Pixel value of the (Noise) Reference image.\par

Choose a Pixel value (8 or 16bits) as a value away from zero, you can specify a value\par

between -1.0 and 1.0.\par

Pixel values do not change when the same value is specified here.\par

Depending on the magnitude of the reference Pixel value, values will change.\par

The default value is 0.5.\\

\\

Hue\par

It specifies the intensity of the color (Hue) change.\par

The value will scale with the Offset value.

\newpage

\thispagestyle{empty}

\ \vspace{-0.2em}

\par

You can use a value from -1.0 to 1.0.\par

The image will not change when the value is 0.\par

The default value is 0.0.\\

\\

Lightness\par

Specify the strength of the brightness (Lightness) change.\par

The default value is 0.25.\par

Other options are the same as \textquotedbl Hue\textquotedbl .\\

\\

Saturation\par

Specify the strength of the chroma (Saturation) change.\par

The default value is 0.0.\par

Other options are the same as \textquotedbl Hue\textquotedbl .\\

\\

Alpha\par

Specify the strength of the opacity (Alpha) change.\par

The default value is 0.0.\par

Other options are the same as \textquotedbl Hue\textquotedbl .\\

\\

Premultiplied\par

When ON, RGB is already set to Premultiply\par

(The value of Alpha channel is multiplied in advance RGB channels)\par

and processes as an image.\par

At that time, and added to the Alpha processing, you may not get the correct image.\par

The default setting is ON.\\

\\

Reference\par

Choose how Reference image values put the strength of the effect into each Pixel.\par

An image is connected to the \textquotedbl Reference\textquotedbl \ of the input,\par

Choose from Red/Green/Blue/Alpha/Luminance/Nothing.\par

Choose Nothing when you do not want this effect, it will turn off the connection.\par

The default setting is Red.
