Samsung Patents a Camera That Blends Old Photos With Live Shots

By Patentlyze Team · Updated Jul 3, 2026

Samsung is patenting a way for your phone camera to blend a photo already sitting in your gallery with a brand-new live shot, creating a merged double-exposure image in one step.

What Samsung's multi-exposure blending actually does

Double-exposure photography is a classic darkroom trick where two different images are layered together into one ghostly, dreamlike photo. Phones can already do this, but it usually means shooting both images in the same session.

Samsung's patent describes a system that lets you pick any old photo from your camera roll and merge it with whatever your camera is pointing at right now. The phone's processor automatically adjusts the stored photo to fit the aspect ratio of the new shot before blending them together, so the proportions line up cleanly.

The result is a single combined image that pulls from two completely different moments in time. You could, for example, layer a landscape you shot last summer onto a portrait you're taking today, and the phone handles the sizing and blending for you.

How the processor matches and merges the two images

The patent describes a four-step image pipeline running on the device's processor:

• First image: A live capture pulled directly from the phone's image sensor.
• Second image: Any photo already stored in the device's memory (your gallery).
• Third image: A version of the stored photo that has been resized or cropped to match the aspect ratio of the live shot, so both images are geometrically compatible for blending.
• Fourth image: The final output, created by synthesizing (layering) the live shot and the adjusted stored photo together.

The key technical step is that aspect ratio normalization happens automatically. When you shoot a photo in 4:3 but your gallery photo is in 16:9 or a square crop, the system figures out how to transform the stored image so it can merge cleanly with the new capture.

The claim language specifies that the third image must be "capable of multi-exposure synthesis" with the first, which suggests the processor is doing more than a simple resize. It may also be adjusting opacity, alignment, or tone so the blend looks intentional rather than jarring.

What this means for Galaxy camera features

For Samsung, this fits squarely into the camera differentiation race among flagship Android phones. Galaxy devices already ship with a range of creative shooting modes, and a gallery-to-live-shot blending tool would be a natural addition to that lineup, giving photographers a reason to stay in Samsung's own camera app rather than reaching for a third-party editor.

For you, the practical upside is that double-exposure effects that currently require desktop editing software or a separate app could become a one-tap in-camera feature. The fact that the processor handles the aspect ratio mismatch automatically is the part that matters most: today, combining two differently sized photos into a coherent blend takes real manual effort.
