(Phase Detection Auto-Focus) A camera technology that uses sets of dedicated light sensors aimed at different areas of the camera lens to measure exactly how out-of-focus the image is, so the lens can be focused quickly and accurately.
Which is better PDAF or AF?
PDAF pros and cons
PDAF uses the phase difference to almost immediately calculate how far the lens needs to travel to achieve focus. Phase detection AF is faster and more accurate than traditional contrast AF.
What are PDAF pixels?
Dual Pixel autofocus is an extension of Phase Detection autofocus (PDAF), featured in smartphone cameras for some years. Essentially, PDAF uses dedicated left-looking and right-looking pixels on the image sensor to calculate whether the image is in focus.
How can I check the quality of my smartphone camera?
Checking megapixel count on an Android phone
Just open the camera app, click the settings icon (the small cog) and you should find the megapixel information listed under the heading “Photo size”.
What does F mean in mobile camera?
Aperture (f/stop): It is the opening of a lens‘ which basically controls the amount of light that can pass. The second most commonly used term in the smartphone camera is aperture.
What is PDAF sensor?
Phase Detection Auto Focus (PDAF)
PDAF Technology uses paired masked pixels on the image sensor, designed to mimic your eyes. The ISP adjusts the camera lenses until both images are synchronized with each other and the subject deemed to be in focus.

Which one is better OIS or EIS?
OIS primarily improves low light photography by physically compensating for hand shake within each single frame, and EIS improves shaky video by maintaining a consistent framing between multiple video frames. OIS is primarily for photo, and EIS is only for video.
What is OIS camera?
Samsung’s Optical Image Stabilization system, or OIS, uses a combination of hardware and software processing that’s advanced enough to deliver clear and sharp photos even in low light thanks to the big sensor on the Galaxy S and Note series.
What does 12mp Dual Pixel mean?
Dual pixel technology effectively divides every single pixel into two separate photo sites. Each pixel consists of two photodiodes that sit side by side next to each other under a micro lens. While focusing, the two photodiodes receive different inputs as they receive light from separate angles.
Is 48 MP better than 12 MP?
The larger the pixel size, the more light each pixel can capture. A 12MP half-inch sensor would produce far cleaner low light shots than a 48MP half-inch sensor, given that every other variable is equal.
How many megapixels is good for a camera?
A decent 6-megapixel camera is good enough for most normal camera usage. Go for higher megapixels only if you wish to use your images for canvas-sized prints or large hoardings. If your interest is in night sky photography, then too a higher megapixel camera can be important.
Is a 64MP camera good?
Benefits of 64MP Quad-Pixel sensors
For instance, Samsung’s 64MP GW1 sensor is 33% larger than its 48MP counterpart. As our experience with 48MP sensors has corroborated, these sensors haven’t been designed for use at full resolution and the 64MP sensors will yield the best results at 16MP resolution.
Which camera aperture is best?
An f/4.0 maximum aperture is generally good in medium lighting levels. An f/5.6 maximum aperture requires good lighting or image stabilization unless outdoors before sunset. If you are shooting landscapes from a tripod, you are likely happy with f/8.0 or f/11.0. That your lens opens wider may be of little importance.
Is a bigger aperture better?
A higher aperture (e.g., f/16) means less light is entering the camera. This setting is better for when you want everything in your shot to be in focus — like when you’re shooting a group shot or a landscape. A lower aperture means more light is entering the camera, which is better for low-light scenarios.
What aperture is best?
Ideally, you would use a lens with a maximum aperture of f/2.8 or wider. When trying to get pinpoint stars, the goal is to let in as much light as possible (the stars are not that bright, after all). The way to increase exposure is to open up the aperture, slow down the shutter speed, and increase the ISO.
What is omnidirectional PDAF?
In photography, an omnidirectional camera (from “omni”, meaning all), also known as 360-degree camera, is a camera having a field of view that covers approximately the entire sphere or at least a full circle in the horizontal plane.
How does mobile camera autofocus work?
Essentially, it’s an auto-focus system based on trial-and-error. The lens on your camera phone is moved back and forth until the position of maximum focus is found for the object. In order to determine when an image is in focus, your smartphone uses an algorithm based on measuring the contrast.
What is laser autofocus?
Laser focus. Laser focus helps cameras find focus even faster than cameras with autofocus only. It finds focus in challenging lighting conditions, such as scenes with low light or contrast. The out-of-the-box-ready feature is a fully automatic solution, requiring neither setting nor programming to work.
