ImageMultiply

multiplies each channel value in image by a factor x.

gives an image in which each pixel is the product of the corresponding pixels in

and

If the image dimensions are different, ImageMultiply multiplies into the center of .

If or is a single-channel image, its values are multiplied by the values in each channel of the other image in ImageMultiply.

If and are both multichannel images, the values in each channel are multiplied separately.

ImageMultiply gives an image with the same underlying data type as image, clipping or truncating values if necessary.

ImageMultiply gives an image with the largest type of either or , clipping or truncating values if necessary.

For binary images, ImageMultiply effectively finds the logical AND of pixel values.
