What are Megapixels on a Digital Camera?

Updated Jun 27, 2022 11:12 PM

What are megapixels on a digital camera? Megapixels are the representation of pixels in millions. For example, one megapixel represents one million pixels. When light flows through a camera lens such as the Carl Zeiss Vario-Sonnar T lens, the image sensor captures it in the millions of light-capturing cavities known as photosites. The photosites are light collectors on the image sensor that are represented in columns and rows. So, if a professional or beginning photographer uses a top-rated camera with say 8MP, it means that they will capture pictures with about eight million small squares of details per inch.

KEY TAKEAWAYS:

  • Megapixels are the representation of resolution in a digital camera.
  • High megapixels does not mean that you get a clearer picture, it only means that you can enlarge and crop images without exposing individual pixels.
  • Do not purchase a camera because of high megapixels. Instead, buy a camera like a Canon EOS that has a large sensor, better lens quality, and a compelling image processor.

What is the Relationship Between Pixel Size and Megapixels?

At the center of your camera, e.g., a Carl Zeiss camera, is an image CMOS or CCD sensor that comes in different sizes for different cameras. Large image sensors have larger pixels because they can collect a lot of light. With better lighting conditions, the collection of light can lead to clearer photographs.

When light flows through a camera lens such as the Carl Zeiss Vario-Sonnar T lens, the image sensor captures it in the millions of light-capturing cavities known as photosites.

You can determine the size of an image sensor, for instance, the Carl Zeiss camera image sensor, by looking at the diameter of the lens, e.g., the Carl Zeiss Vario-Sonnar lens. Now, a smartphone with 8MP crams eight million pixels in a very tiny sensor. In contrast, a large camera sensor like the 20.2-megapixel camera sensor with eight million pixels would have large pixels. The pixels in this camera hold more light without causing noise and blurs. But realistically, a camera with digital or optical zoom, and a large camera sensor today will have more megapixels.

There are smartphone cameras with 108MP and a higher resolution than good DSLRs like the Canon EOS camera. However, the pixels have to fit in a tiny sensor compared to the sensor of full-sized cameras. As a result, the pixel size in smartphone cameras is smaller.

Advanced compacts, mirrorless cameras, and pro & semi-pro DSLRs come with very large image sensors, providing large pixel sizes. The most common sensor sizes are the Full-Frame (36mm x 24 mm) and APS-C (approx. 22mm x 15 mm). As a result, an 8MP DSLR offers a superior image to an 8 MP compact camera. In the same way, the compact camera, e.g., the -HX99 18.2MP Compact Digital Camera (Silver) or the Sony DSC-W830/W800/W810 digital camera will provide gorgeous images with brilliant colors than a smartphone camera. 

Other cameras use digital rangefinder mechanisms to focus and shoot quality pictures. While most of these cameras were popular in the recent past, you can still learn what digital rangefinder cameras are.

How Many Megapixels Do I Need?

Generally, people prefer to go with more. The reason is that each pixel contains information about the light and color of the subject. The more information the Carl Zeiss camera sensor captures, the better the resolution of the final image. In addition, you can choose to get a Lecran vlogging camera with smile detection sensitivity and capture the beautiful smiles of your family members, friends, or even clients.

A 16MP Nikon COOLPIX should technically produce a better image quality than an 8MP camera. The video products you get with a 16X digital camera will have a pop color, especially with better light conditions. The difference between an 8MP and a 20MP image from a compact or pocket camera may not be different when you look at their detailed photos on the screen. But if you print the detailed images in various sizes, you will see the quality and difference in the results.

Although digital camera megapixels increase each year, the image sensor size remains the same. Therefore, there is a threshold, where more pixels in a sensor like the Panasonic Lumix DC-FZ80 sensor do not translate to a better image. However, you can have better image quality with larger pixels in a large camera 1.0 Type stacked CMOS sensor or CCD image sensor.  This is why you should have a pretty good understanding of what the advantages of a digital camera are so that you can take advantage of them.

F.A.Q.

Does it mean that more megapixels translate to better image quality when shooting a panoramic image of wide landscapes with a digital camera (Black)?

No. A camera with fewer megapixels, better image sensors, and quality lenses can produce sharp images than a camera with more megapixels.


Can I use digital point-and-shoot cameras like the Panasonic Lumix DC-FZ80 with a high megapixel for my artwork?

Yes. The more megapixels in the image digital, the more details the camera records. So, point-and-shoot cameras with high image resolution can enable you to print larger prints without worrying about the visibility of the picture’s pixel structure.


What is the ideal MP for a digital camera?

Although professional photographers will choose to go for cameras with 20+ megapixels for quality image and video products, a 12MP camera can still offer quality digital pictures.
