Digitizers convert analog or physical input into digital images by using a touch-sensitive scanning surface that sends signals to software. They emerged in the 1950s and have since become important tools for computer-aided design and converting hand drawings into digital formats like textures and animation. Modern digitizers come in different types, with features like resolution, sensitivity, and image recognition varying between tablet-style digitizers that use a stylus for input and more advanced digitizers that leverage lasers or camera pens.

3. What Is a Digitizer?
Digitizers convert
analog or physical
input into digital
images.

4. History
Modern digitizers came
about in the 1950s.
 Digitizers of that era
were often confused with
scanners, as in converting
any image into "digital."

5. Identification
Modern digitizers appear
as flat scanning surfaces.
 The surface is touch-
sensitive, sending signals to
the software.

6. Significance
Digitizers carry out important
work in computer-aided design.
They also help convert hand-
drawn images into textures and
animation.

7. Features
 Important features
when looking at digitizers
are resolution, sensitivity
and image recognition.

8. Types
In addition to the tablet itself,
digitizers have an input stylus that
acts as a pen.
 More advanced designs offer
better accuracy with lasers and even
camera pens.
