I finally understood why the circular smartphone camera lens took a rectangular image

Everything that happens has a reason and this is why the camera lens is round and the image is rendered rectangular / square!

When looking at camera lenses on good cameras on smartphones, what are their shapes? Round, that's right. However, the photo is rectangular / square. Have you ever wondered about this strange thing

In fact, things are quite simple because different from many people's misunderstandings, lenses don't directly produce images. Instead, the lens coordinates with another important part in the camera / smartphone to create the image.

In antique cameras, this component is film, while with digital cameras / smartphones, this part is an image sensor.

Not the part that directly creates the image, it works closely with the sensor on the digital device to do this.

When the light reflects back from the subject you are shooting, the light goes into the camera lens and the lens's mission is to 'break' the light and focus it on the film or image sensor.

The first camera manufacturers figured out that circular lenses could make the most of the light collection into the film and therefore the round shape was chosen.

So if the camera lens is round, why are the movies rectangular? Try thinking about all the images you see, whether it's photos, drawings or posters, most of them are rectangular or square.

The reason for this is simple, squares or rectangles make it easier to create photo frames, besides this shape also helps paintings, photos easily hang on walls of the same shape.

Rectangles are the most suitable size of films in a film.

Also, if you've ever seen a film, you probably know its scrolling mechanism every time an image is taken. Therefore, a series of rolled up rectangular pieces of film will be easier and more efficient than oval or any other shape.

Similarly, digital cameras and smartphones also follow this 'style'. Besides, using a rectangular sensor is also said to bring better images.

A circular lens can produce a circular image inside the camera. However, the outer edges of this circular image are likely to be more distorted than those located deep in the center.

This is the result of the work being more bent to reach the edge. Therefore, for better quality images, rectangular sensors cut out the edge of the recorded image from a circular lens.

Simply put, it will retain the best part of the image recorded from the lens.

Technology is truly amazing!
