Light Scope - Lux Meter
LightScope is a comprehensive solution providing professional light measurement and analysis using your device's camera sensor.

【Key Measurement Features】
• Illuminance (lux) Measurement: Calculates accurate illuminance by analyzing EXIF data from the camera sensor. Illuminance is derived using the formula: (F-number² / (Exposure Time × ISO)) × Calibration Factor.
• Luminous Intensity (candela) Calculation: Automatically calculates the luminous intensity of a light source based on the set distance. Uses the formula: Illuminance (lux) × Distance².
• Color Temperature (K) Analysis: Precisely measures color temperature in the range of 1500K~15000K by converting RGB values to XYZ color space using McCamy's formula.
• Real-time Histogram: Visualizes the balance of shadows, midtones, and highlights through 16-level brightness distribution analysis.
• Contrast Ratio Measurement: Evaluates the ratio between the brightest and darkest parts of a scene according to WCAG accessibility standards.
• Noise Measurement (SNR): Calculates the signal-to-noise ratio in dB to evaluate image quality in the shooting environment.

【Advanced Features】
• Image Capture and Storage: Captures camera images at the time of measurement and stores them with measurement data.
• Full-screen Image View: Zoom, pan, and rotate captured images for detailed inspection.
• Gallery Saving: Save captured images to your device's photo library.
• Measurement History and Trends: Save all measurements chronologically and visualize trends with graphs.
• Camera Full-screen Mode: Hide panels to focus on the camera view while checking key measurements via a mini info panel.
• Perfect Dark/Light Mode Support: All UI elements automatically adapt to the system theme.

【User Settings】
• Illuminance Calibration: Adjust the calibration factor for more accurate measurements based on your environment.
• Distance Setting: Set the distance to the light source for precise luminous intensity (cd) calculations.
• Front/Rear Camera Selection: Choose the appropriate camera for your measurement situation.

【Technical Features】
• Support for measuring various light source types: natural light, LED, fluorescent, incandescent, etc.
• Algorithm optimization for stable color temperature calculation even in low-light environments
• 10-frame moving average filter for measurement stabilization
• Center-weighted image analysis for accurate evaluation of main subject quality
• Automatic exposure quality assessment based on histogram analysis

Perfect tool for photographers, videographers, lighting designers, UI/UX developers, and anyone who needs accurate light measurements.
