This image and the sharpest short-exposure frame are then sent through neural networks, which choose between these two images (my edit: 12 MP + 12 MP = 24 million pixels analysis) for the best pixel to ultimately represent this photo.
Three of the standard-exposure shots which display the best color, tones, and other low-frequency data are then fused with the long-exposure frame to compose a single image. Therefore, the sharpest image of this series is chosen to move on to the next step. The short exposure shots are meant to freeze time and bolster high-frequency details like grass blades or stubble on a person’s face. A ninth picture is then taken with a long exposure when the shutter button is triggered.
Of the eight images, four are taken with standard exposure, and four with short exposure. Much like Apple’s Smart HDR, Deep Fusion relies on object and scene recognition, as well as a series of eight images captured before you click the shutter button. (NOTE: A14 likely is able to do below stuff even better because the huge Neural Engine of A14 is gigantic and much more advance than A13.) What is Deep Fusion? This is for A13 (iPhone 11) but applies to A14 (iPhone 12) as well. If view HDR is off in the settings of the photos app, it doesn’t flicker.Īnyone notice this yet on the 12 pro? It’s very minor and livable but want to make sure it’s somewhat normal. I read this HDR/flickering was an issue on the 11 pros too. Is this what’s happening here? I never saw this little delay to create the final image before on the XS.Īlso, I noticed that if “view HDR” is set to on in the photos app and I open up a photo that was taken that has HDR, there’s a little flickering as if it’s trying to adjust but then it stops. I remember reading that the more complex camera system takes different readings with each lens and then puts it all together to create one nice image. It’s like a slight delay as the phone is creating the image. I noticed that right after I take a regular photo and then open it up to preview it, it’s blurry at first then quickly gets sharp and the colors / exposure fluctuates and shifts a little. I got a 12 pro yesterday (coming from an XS) so never really used the new camera system.
