3. Android versiyonlari End Android Kamera API Problemleri Cihaz ve Üretici

   Çeşitliliği Karmaşık API

4. CameraX nedir? • Daha kolay kamera uygulamaları geliştirmeye yardımcı •

   Açık kaynak • Alpha

5. Android 5+ End CameraX Tüm köşe senaryolar kapsanmış Arka planda

   Camera2 API kullanan basit API

6. CameraX • Lifecycle ile uyumlu • Portrait, HDR, Night, ve

   Beauty • Eklenti alabiliyor

7. CameraX Ön İzleme Görüntü Analizi Görüntü Yakalama

8. Ön İzleme

9. val viewFinderConfig = PreviewConfig.Builder().build()

10. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder)

11. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder) preview.setOnPreviewOutputUpdateListener

    { previewOutput -> //use previewOutput.surfaceTexture if needed }

12. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder) preview.setOnPreviewOutputUpdateListener

    { previewOutput -> //use previewOutput.surfaceTexture if needed } CameraX.bindToLifecycle(this, preview)

13. val viewFinderConfig = PreviewConfig.Builder().build() val preview = AutoFitPreviewBuilder.build(viewFinderConfig, viewFinder) preview.setOnPreviewOutputUpdateListener

    { previewOutput -> //use previewOutput.surfaceTexture if needed } CameraX.bindToLifecycle(this, preview)

14. Görüntü Analizi

15. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build()

16. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis =

    ImageAnalysis(imageAnalysisConfig)

17. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis =

    ImageAnalysis(imageAnalysisConfig) imageAnalysis.setAnalyzer { imageProxy, rotationDegrees -> //do image analysis }

18. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis =

    ImageAnalysis(imageAnalysisConfig) imageAnalysis.setAnalyzer { imageProxy, rotationDegrees -> //do image analysis } CameraX.bindToLifecycle(this, imageAnalysis, preview)

19. val imageAnalysisConfig = ImageAnalysisConfig.Builder() .setTargetResolution(Size(1280, 730)) .build() val imageAnalysis =

    ImageAnalysis(imageAnalysisConfig) imageAnalysis.setAnalyzer { imageProxy, rotationDegrees -> //do image analysis } CameraX.bindToLifecycle(this, imageAnalysis, preview)

20. Görüntü Yakalama

21. val imageCaptureConfig = ImageCaptureConfig.Builder() .build()

22. val imageCaptureConfig = ImageCaptureConfig.Builder() .build() val imageCapture = ImageCapture(imageCaptureConfig)

23. val imageCaptureConfig = ImageCaptureConfig.Builder() .build() val imageCapture = ImageCapture(imageCaptureConfig) CameraX.bindToLifecycle(

    this, preview, imageCapture, imageAnalyzer)

24. val imageCaptureConfig = ImageCaptureConfig.Builder() .build() val imageCapture = ImageCapture(imageCaptureConfig) CameraX.bindToLifecycle(

    this, preview, imageCapture, imageAnalyzer)

25. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file:

    File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } }

26. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file:

    File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } } val photoFile = createFile(outputDirectory, FILENAME, PHOTO_EXTENSION)

27. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file:

    File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } } val photoFile = createFile(outputDirectory, FILENAME, PHOTO_EXTENSION) imageCapture.takePicture(photoFile, imageSaveListener)

28. val imageSaveListener = object : ImageCapture.OnImageSavedListener { override fun onImageSaved(file:

    File) { //use the image file } override fun onError(useCaseError: ImageCapture.UseCaseError, message: String, cause: Throwable?) { //handle error } } val photoFile = createFile(outputDirectory, FILENAME, PHOTO_EXTENSION) imageCapture.takePicture(photoFile, imageSaveListener)
