latent image

[′lāt·ənt ′im·ij]
(graphic arts)
An invisible image produced by the physical or chemical effects of light on the individual crystals (usually silver halide) of photographic emulsions; the development process makes the image visible, in the negative.

latent image

An invisible image typically of electrical charges. For example, in a copy machine, a latent image of the page to be copied is created on a plate or drum as an electrical charge.

Different densities constituting the visible processed silver image originate from the latent image of the crystals.
Combination of high voltage of scorotron net (-850V) applied on photoconductor drum to charge it on uniform potential and the strength of laser power (laser strength 12) to selectively discharge preset areas on photoconductor produces an electrostatic latent image (potential difference) of the original document on the surface of drum.
The traditional method for developing the CR latent image was to use a laser beam "flying-spot" that was deflected by an alternating mirror across the advancing PSP imaging plate in a raster fashion.
Some high schools instead opt to print report cards on paper imbedded with a latent image such as the word "void"--that shows up on photocopies or computer scanned images of the documents.

The light from your scene actually changes the electrical charge in each silver halide crystal, making an invisible image, or latent image, that is sensitive to film developer (a chemical used to develop film).
The database has a total of 258 latent cases; each case includes the latent image, the matching tenprint image, and four sets of minutiae that have been validated by a professional team of latent examiners.
In photography, "the image is already immanent in the exposed film, and the process of development simply makes this latent image apparent.
Wilson insists that "the microscope both undermined confidence in the manifest image of the world and, in supplying a glimpse of a latent image, gave sense to the idea of a nonoccult interpretation of nature" (p.
A latent image, invisible to the eye and composed of positive electrical charges, is formed on this drum.
Upon exposure the plate stores a latent image which is then scanned by the ScanX.
