  ...

  async takePicture() {
    if (this.camera) {
      const options = { quality: 0.5, base64: true, skipProcessing: true, forceUpOrientation: true };
      const data = await this.camera.takePictureAsync(options);
      const textRecognition = await RNTextDetector.detectFromUri(data.uri);
      console.log('Text Recognition', textRecognition);
    }
  };

  ...
