Frame processors are functions that are written in JavaScript (or TypeScript) which can be used to **process frames the camera "sees"**.
Inside those functions you can call **Frame Processor Plugins**, which are high performance native functions specifically designed for certain use-cases.
For example, you might want to create a QR code scanner **without writing any native code**, while still **achieving native performance**:
For example, you might want to create a [Hotdog/Not Hotdog detector app](https://apps.apple.com/us/app/not-hotdog/id1212457521) **without writing any native code**, while still **achieving native performance**:
```jsx
function App() {
const frameProcessor = useFrameProcessor((frame) => {

const qrCodes = scanQRCodes(frame)
console.log(`Detected QR Codes: ${qrCodes}`)
const isHotdog = detectIsHotdog(frame)
if (isHotdog) {

* Creating **color filters** with depth-detection
Because they are written in JS, Frame Processors are **simple** and **easy to create** while still maintaining **native performance**. (Frame Processors can run up to 1000 times a second!) Also, you can use **over-the-air updates** to tweak the Hotdog detector's sensitivity without pushing a native update.

Frame Processors require [**react-native-reanimated**](https://github.com/software-mansion/react-native-reanimated) 2.2.0 or higher.

### Interacting with Frame Processors
Since Frame Processors run in Worklets, you can also easily read from, and assign to [**Shared Values**](https://docs.swmansion.com/react-native-reanimated/docs/shared-values):
