Saludos vicbit,

Gracias por utilizar los Foros de Discusión de National Instruments. Puede utilizar el IMAQ Merge Overlay VI. Le comparto algunos links útiles que le pueden servir como referencia:

IMAQ Merge Overlay VI:

Makes a nondestructive overlay part of the image content. This process creates a destructive overlay. The VI then removes the nondestructive overlay. The resulting image is an RGB image.

How to use Merge Overlay:
If you have a 10-bit image that you are attempting to merge with a text overlay, this works fine if the image is acquired as an 8-bit image. However, if you try to acquire the image as a 10-bit image, copy it, and merge the overlay into the copy, the intensities of all pixels are increased significantly, making the text illegible. This problem repeats if you try to cast the image into 8-bits as well. In order to get a detailed and increased resolution of the 10-bit image, you should use the IMAQ Image Bit Depth function to specify the bit-depth of the new copy of the image. Use this function and specify a bit-depth of 10, and then use the Overlay Text and Merge Overlay functions to create your new image.

Quedo al pendiente, saludos cordiales.
