Introduction

Nowadays it is common to confuse the terms real image e virtual image. Although both concepts are closely related to the visual representation of objects, there is a clear difference between them.

Real image

The real image is one that can be observed directly and what is captured by a receiving device, whether our body or a camera, without any intermediation process. This type of image is totally objective and faithfully represents reality.

Examples of real image:

• The image we perceive with our own eyes.
• The photograph taken with an analog or digital camera.
• The image captured by microscopes and telescopes.

virtual image

The virtual image, on the other hand, is a graphic representation created by a computer by manipulating data and applying algorithms. This type of image is completely subjective, since its appearance depends on the software used and the way in which the data is manipulated.

Examples of virtual image:

• Video games and 3D animations.
• Maps and GPS navigation systems.
• Images generated by graphic design and image editing software.

Conclusion

In summary, the main difference between the real image and the virtual image lies in their origin. The first is the result of the direct capture of visual signals from the real world, while the second is a graphic representation generated by a computer through algorithms and processed data.

It is important to take this distinction into account in order to better understand how different computer technologies and applications that use images and graphics work. For example, in the field of architecture and engineering, both real and virtual images are used to present projects and plans.
