Adaptive Magnifier uses advanced image algorithms that delivers crisp clear photos under any light and color conditions. Magnifier will make the image better viewable by increasing the contrast of every part of the image.

It is a feature rich app with many functionalities waiting for you to discover:

Main algorithm is supported by more visual adjustments like noise removal, gain and exposure controls.
Focus modes: Tap to focus, auto focus, macro, locked, repeat, infinity.
Color, gray and black and white, black & white inverted, blue yellow, black yellow filters.
Additional digital 10x zoom applied on top of phones zoom. (i.e. if you phone has 8x zoom you will have a total of 80x zoom)
Virtual reality mode (VR)
Compass - in horizontal and vertical phone modes.
Angle cross-hair.
Pitch level.
Camera controls like zoom, switch to front face camera, flash and off course fast capture.
Full portrait/landscape support.
Night-scan existing photos from your device.
Edited photos can be used as wallpaper or be shared with any method available, like to Facebook, TikTok or upload to cloud.
A ton of customization options! You can adjust shutter sound, bright screen, volume key functions, record with audio, burst shooting, grid lines, crop guide, video and image resolution, capture size, various display information and many more.

Adaptive magnifier allows you to save photos from camera, record videos and apply effects on photos from gallery.

The algorithm used is now revealed! It is called Adaptive histogram equalization a digital image processing technique used to enhance the contrast of images. It differs from normal histogram equalization in the respect that the adaptive method enhances the contrast locally. Algorithm is greatly used in medical imaging like endoscopes, x-rays, space images from NASA and in general in cases were camera vision is difficult.

Disclaimer: Digital zoom is not real zoom (like optical zoom) and it will produce blurry and unclear images but it can be a good feature when reading text.
