One megapixel is equal to one thousandth of a millimeter, or the thickness of a human hair. So if a camera has one thousandth of a millimeter of image resolution, it measures about 8 cm. The exact number of megapixels may vary slightly, and the answer may depend on the camera.
If a camera has 1.8 megapixels, then the lens is 1.8 inches or 10.7 centimeters, so its lens takes up about 1.75 inches of the camera’s field of view.
Here’s another example of different kinds of cameras—a smartphone. Each megapixellated component of a smartphone’s camera has a different amount of light, so we’re not talking about a fixed number of images or the amount of light. Instead, the cameras are different sizes:
Here, the iPhone uses four megapixels per eye. The camera has no sensors and is based on light passing through a chip.
Here, the camera uses one megapixel per eye, which is the same size as the iPhone’s sensor.
The difference between a one megapixel phone and many megapixels does increase resolution, but only by about 10 percent.
Can you read what’s written on these pictures?
To be fair, it’s all computer generated. The actual images are on a single disk mounted on a computer and are read by software that takes a photograph.
But there’s a problem with these images: There are none that are really readable.
The New York Times, in a Sunday front page story, reported that Russian hackers are attempting to plant malware on the computers of people in the U.S. who read or receive news about Russia. They are also attempting to plant malware on the computers of people in other countries, possibly including European ones to try to compromise them.
However, all the evidence that the Times has is about Russian cyberattacks on other countries.
Here is what the U.S. government has done in response to these Russian cyberattacks:
Congress passed the Cybersecurity Act, which requires more cyber-attacks against foreign targets. President Obama signed it into law on Sept. 27 2016, and in February of next
