Camera Test
Grant camera permissions. Check the video feed for defects, frame rate, and sensor noise.
Does this photo look clear and sharp?
Check for blur, distortion, color issues, or artifacts
How to Use This Test
Grant Camera Permission
Click 'Start Camera' and allow camera access when your browser prompts you. Ensure no other application is currently using the camera.
Check the Live Preview
Verify the video feed shows a clear, well-lit image. Check for focus quality, color accuracy, and that the correct camera is active (front or rear on mobile).
Take a Snapshot
Click 'Take Snapshot' to capture a still image from the camera feed. This freezes the current frame on a canvas for closer inspection.
Rate Your Camera
If the snapshot looks sharp and clear, tap 'Video Feed Flawless'. If the image is blurry, dark, or distorted, select 'Camera Defective'.
What Your Results Mean
Video Feed Flawless
Your camera produced a clear, focused image with accurate colors. The camera hardware and driver are functioning correctly.
Camera Defective
The camera feed showed significant issues — blurriness, distortion, black screen, or severe noise. This indicates a potential hardware or driver problem.
Image is Dark or Overexposed
Poor exposure can indicate a dirty lens, incorrect lighting, or auto-exposure malfunction. Try adjusting your lighting and cleaning the lens before concluding it's a hardware defect.
Camera Feed is Laggy or Choppy
Low frame rate in the preview can be caused by USB bandwidth limitations (for external webcams), high CPU usage, or insufficient lighting forcing the camera to use slower exposure times.
Common Problems and Fixes
Camera shows a black screen
Close other applications that might be using the camera (Zoom, Teams, FaceTime). Check browser and OS camera permissions. On Windows, go to Settings > Privacy > Camera. On macOS, check System Preferences > Security & Privacy > Camera.
Camera feed is extremely blurry
Clean the camera lens with a soft microfiber cloth — fingerprints and smudges are the most common cause of blur. If the lens is clean but the image remains blurry, the autofocus mechanism may be failing.
Wrong camera is active (rear instead of front)
Some browsers default to the rear camera on mobile. The test requests the user-facing camera, but you can switch cameras in your OS settings. On mobile, ensure 'facingMode: user' is respected by your browser.
Snapshot appears stretched or distorted
Aspect ratio issues can occur if the camera's native resolution doesn't match the display container. This is typically a cosmetic issue with the preview and doesn't affect the actual camera sensor quality.
USB webcam not detected by the browser
Ensure the webcam is plugged into a working USB port. Try a different port or cable. Check Device Manager (Windows) or System Information (macOS) to verify the device is recognized. Restart the browser after connecting.
Frequently Asked Questions
Why does the browser ask for camera permission?
Browsers require explicit user consent before any website can access your camera. This is a mandatory privacy protection. Click 'Allow' when prompted — permission is only granted for the current session and revoked when you close the tab.
Is my camera feed recorded or uploaded to a server?
No. The camera feed is processed entirely in your browser using the MediaDevices API. The snapshot is rendered on an HTML canvas element and stored locally in your device memory. Nothing is transmitted to any external server.
The camera feed is black or shows an error. What should I do?
First, check if another application is using the camera — close video call apps like Zoom or Teams. Verify camera permissions in your browser and OS settings. Try refreshing the page. If the issue persists, the camera hardware may be defective or physically obstructed.
Why is my camera image mirrored or reversed?
Most front-facing cameras display a mirrored preview by default, similar to looking in a mirror. This is a standard UX convention. The actual snapshot captured may or may not be mirrored depending on the browser implementation.
Does this test work with external USB webcams?
Yes. The browser accesses whichever camera is set as the default in your OS. Connect your USB webcam before starting the test and ensure it's selected as the default camera in your OS camera settings.
What resolution does the camera test use?
The test uses your camera's default resolution as negotiated by the browser. Most built-in webcams default to 720p (1280x720) or 1080p (1920x1080). The actual resolution depends on your camera hardware and browser capabilities.
My camera image is blurry. Is this a hardware problem?
Blurriness can be caused by a dirty lens (clean with a microfiber cloth), autofocus failure, incorrect focus distance, or low resolution. Try cleaning the lens first. If the image remains blurry across different distances and lighting conditions, the autofocus mechanism may be failing.
