ReFrame – The EPaper Camera
摘要
reFrame 是一款实验性相机，配备六色 ePaper 显示屏，拍摄后照片需 15 秒逐色显现，效果介于报纸半调与老式游戏机之间。关机后屏幕仍保留照片，只有拍新照片才能清除，闲置时作为桌面相框。硬件与软件完全开源，基于树莓派 Zero、Pi Camera 3 和 4 英寸 E Ink Spectra 6 显示屏，用户可按 GitHub 指南自行组装。照片同时保存数字版本，可通过网页仪表板下载原始与抖动处理后的图片。项目由 Kaloyan Kolev 发起，目前不对外销售，未来可能接受个人订单。
荐读理由
项目提供了完整的开源硬件与软件架构，但依赖特定硬件（树莓派、E Ink 屏），除非你正在做类似硬件产品，否则难以直接迁移到 AI 工程或软件创业项目中。它更多是创意启发而非可复用工具。
原文
reFrame is an experimental camera with a color ePaper display. Designed to capture and display one photo at a time, making every frame deliberate and memorable.
reFrame's ePaper display has six pigments, so photos are dithered before they display on the screen.
The dithered photos look somewhere between a newspaper halftone and an old video game.
The processing is part of the fun: you watch the colors come in one by one, like a digital polaroid.

After you press the shutter, each photo takes 15 seconds to fully appear. The display uses electrical charges to physically move ink particles into place.
With ePaper, the photo on screen stays there even after powering off.
The only way to clear the screen is to take a new photo.

When not in use, reFrame doubles as a desk photo frame. Your last photo stays on screen, and the processing gives each image a unique, almost print-like quality.
With the help of APOSSIBLE, we sent the camera to four professional photographers around the world.

Build your own reFrame
reFrame's hardware and software are open source. The camera uses only off-the-shelf components, so you can build one yourself. Everything you need is on GitHub.
Frequently asked questions
who's making this?
reFrame is a passion project by Kaloyan Kolev and friends.
can i buy one?
not yet! the current version of reFrame was designed as an open source project, so you can build your own following the guide on GitHub. i hope to start taking individual orders in the near future.
what's inside?
a Raspberry Pi Zero, Pi Camera 3, 4" eInk Spectra 6 color display and a battery.
do the photos get saved?
yes! the photos you take with reFrame are saved digitally. While the ePaper display remains the primary way to experience each shot, you can also download both the original and dithered versions of each photo using a web dashboard.
