Artificial intelligence (AI) is everywhere, and if you haven't yet got an AI-powered smartphone, you probably soon will do. Is it all just marketing hubris, or is AI in a smartphone – and particularly, in its camera – something we should all aspire to have? With the term AI increasingly being used not only in smartphones, but in all kinds of cameras, it pays to know what AI is actually doing for your photos.
What is AI?
AI is a genre of computer science that examines if we can teach a computer to think or, at least, learn. It's generally split into subsets of technology that try to emulate what humans do, such as speech recognition, voice-to-text dictation, image recognition and face scanning, computer vision, and machine learning. What’s it got to do with cameras? Computational photography and time-saving photo editing, that’s what. And voice-activation.
Voice-activated cameras
The ability for a computer to understand human speech is a form of AI, and it's been creeping onto cameras for the last few years.
Smartphones have been offering Google Now and Siri for a few years, while Alexa is entering homes via the Amazon Echo speakers. Action cameras have jumped on that bandwagon in recent years, with the GoPro action cameras and even dash cams able to take actions when you utter simple phrases such as 'start video', 'take photo' and so on.
AI software
AI is about new kinds of software, initially to make up for smartphones’ lack of zoom lenses. “Software is becoming more and more important for smartphones because they have a physical lack of optics, so we’ve seen the rise of computational photography that tries to replicate an optical zoom,” says imaging analyst Arun Gill, Senior Market Analyst at Futuresource Consulting. “Top-end smartphones are increasingly featuring dual-lens cameras, but the Google Pixel 2 uses a single camera lens with computational photography to replicate an optical zoom and add various effects.”
