Screen resolution is the number of pixels in an image or digital video. The unit helps gauge a screen or monitor’s video orimage quality. 1080p, 720p, and 4K are popular screen resolutions you’ve likely heard about. You might’ve also heard the term HD tossed around a lot. It’s ...
The human visual system is remarkably tolerant to degradation in image resolution: human performance in scene categorization remains high no matter whether low-resolution images or multimegapixel images are used. This observation raises the question of how many pixels are required to form a meaningful...
(Its estimated street price is $1,999, and it will be available in October.) But don’t worry, if you’re looking for your first digital camera (as I am), you’re in luck. There are seemingly more and more cameras to choose from that have new features, and the prices are going ...
Let’s see how exposure is related to the histogram. What is a Histogram in Photography? In photography, a histogram is a graphical representation of the exposure levels (brightness) within an image. It displays how many pixels in the image have a particular tonal value, ranging from pure bl...
Image sensors come in different sizes. The larger the sensor, the larger the pixels can be, and the more photons each pixel can hold. The result is an image that looks cleaner, with less noise or grain, and typically shows a finer distinction between highlights and shadows. ...
megapixels (MP) or more, and there are some monstrosities with 100MP. I still have memories of walking into camera shops as a teenager and seeing the higher end models having 2 megapixels, and probably in fifty years everyone will have 600MP. So what is a pixel, and how many do you...
Clark assumed optimal visual acuity across the field of view; that is, it assumes that your eyes are moving around the scene before you. But in a single snapshot-length glance, the resolution drops to a fraction of that: around 5–15 megapixels. That's because your eyes have a lot of...
When shopping for a new laptop, one of the most important factors to consider is the screen size. The display screen size is what you’ll be looking at all day, so it’s crucial to choose a size that fits your needs. But with so many options available, how do you determine the idea...
