Add iPhone-Style Panorama Feature

Job ID: 40233138

Budget: $30 – $250 USD

We need an Android developer to add iPhone-style panorama to the Open Camera app (open source: https://opencamera.org.uk/).
Goal: Implement panorama in Open Camera so it works like iPhone: guided on-screen motion, smooth horizontal panning, and one stitched panorama image.

• Works seamlessly on both the front and back cameras.
• Guides the user with the same arrow-line UI Apple uses, keeping motion smooth and level.
• Captures a continuous series of frames, stitches them on-device, and outputs one high-quality image without pushing memory limits.

You’ll work only against the official Open Camera codebase (or a clean fork you create). I’ll take your branch and merge it into our own app later.
