- "JPEG output at 0.9 quality for captured photos"

- "Default to back camera (environment) for mobile paper note photos"
|
|
- "Stop camera stream immediately after capture to save battery"

patterns-established:
|
|
- "Camera modal: full-screen black background with centered preview"

|
- "Capture flow: live preview -> capture -> review -> retake/confirm"

# Phase 03 Plan 03: Camera Capture Summary
|
|
|
|
**Full-screen camera modal with getUserMedia, photo capture via canvas.toBlob, and comprehensive feature detection**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-01-29T14:26:55Z
|
|
- **Completed:** 2026-01-29T14:28:23Z
|
|
- **Tasks:** 2
|
|
- **Files created:** 1
|
|
|
|
## Accomplishments
|
|
- CameraCapture modal component with live camera preview
|
|
- Photo capture using canvas.toBlob (JPEG at 0.9 quality)
|
|
- Preview captured photo with retake/confirm options
|
|
- Camera stream properly stopped on close and after capture
|
|
- Front/back camera switching for mobile devices
|
|
- Comprehensive feature detection and error handling
|
|
- Upload integration via fetch to ?/uploadImage action
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: CameraCapture component with getUserMedia** - `8248e0c` (feat)
|
|
- Task 2 (feature detection) was implemented within Task 1 as the functionality was integrated
|
|
|
|
## Files Created/Modified
|
|
- `src/lib/components/CameraCapture.svelte` - Full camera capture modal component (313 lines)
|
|
|
|
## Key Functions Implemented
|
|
- `startCamera()` - Initialize camera stream with getUserMedia
|
|
- `stopCamera()` - Clean up camera stream and video element
|
|
- `capturePhoto()` - Capture frame to canvas and convert to blob
|
|
- `retake()` - Clear capture and restart camera
|
|
- `confirmAndUpload()` - Upload captured photo to server
|
|
- `switchCamera()` - Toggle between front and back camera
|
|
- `handleClose()` - Clean shutdown with proper cleanup
|
|
|
|
## Feature Detection
|
|
- `hasCameraSupport` - Check for navigator.mediaDevices.getUserMedia
|
|
- `isSecureContext` - Verify HTTPS (required for camera except localhost)
|
|
- `NotAllowedError` - Camera permission denied by user
|
|
- `NotFoundError` - No camera available on device
|
|
- 10 second timeout - Prevent indefinite loading state
|
|
|
|
## Decisions Made
|
|
- **JPEG at 0.9 quality:** Balance between file size and quality for uploaded photos
|
|
- **Default back camera:** Most users will photograph paper notes, back camera is more useful
|
|
- **Stop camera after capture:** Save battery while user reviews photo
|
|
- **Full-screen modal:** Typical camera UI pattern, black background
|
|
|
|
## Deviations from Plan
|
|
|
|
**Task 2 merged into Task 1:** All feature detection and error handling was implemented as part of Task 1 since it made more sense to build the complete component with proper error handling from the start rather than retrofitting it.
|
|
|
|
## Issues Encountered
|
|
|
|
None.
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- CameraCapture component ready for integration into entry detail view (03-04)
|
|
- Works with uploadImage action from 03-02
|
|
- Proper cleanup prevents camera indicator from staying on
