What is a megapixel
Friends, welcome to the Trick On Track blog! Today’s topic is “What is a Megapixel?”
We will also explore the difference between the megapixels of a mobile and a camera.
Have you ever bought a mobile or camera and checked how many megapixels the camera has? You might have heard terms like a 32MP, 48MP, 64MP, or 108MP mobile camera. But do you know whether having more megapixels always guarantees better photo quality? It’s not necessarily true. Let’s dive into what a megapixel really is.
What is a Megapixel?
1 MP equals 1 million pixels. Similarly, 12 MP equals 12 million pixels. An image is made up of millions of tiny pixels, and the more pixels an image has, the better its quality. However, this is only possible when the lens of the mobile or camera is large enough.
How Does It Work?
The main component in a camera is the image sensor, which records photographs. The image sensor is a chip that measures the light passing through the lens. When light strikes this sensor, tiny receptors on it measure the intensity of the light.
The lens also plays a crucial role. The more light that reaches the lens, the better the photograph will be.
What Is the Relationship Between the Lens and Megapixels?
Here’s an example: Imagine a water tap and a hand pump. A hand pump delivers much more water than a tap because it has a larger opening. Similarly, the larger the lens, the more light it can capture, resulting in better image quality.
However, this comparison holds true only to a certain extent. For example, a 12MP camera and a 20MP camera may not always show a significant difference in image quality. It depends on the size of the image sensor. The larger the sensor, the better the picture quality.
Example:
An Apple mobile camera, despite being 12MP, often produces images with better resolution than a 48MP camera. Why? Because Apple’s lens has a smaller aperture, which enhances its performance.
Key Takeaway:
Now you understand that along with a higher megapixel count, the sensor size plays a critical role in determining image quality.
