Image quality assessment of still images evaluates key factors affecting imaging performance to ensure optimal results. These include:

• Geometric Distortion
• Chromatic Aberration
• Sharpness
• Resolution
• Light/Color Vignetting
• Flash Uniformity
• MTF across the whole field
• Ringing
• Texture Preservation
• Texture and Edge Acutance
• White Balance
• Color Fidelity
• Dynamic Range
• Tone Curve
• Visual Noise (compliant with IEEE CPIQ)
• Color Sensitivity (for RAW images)

A thorough evaluation of these parameters helps achieve the highest imaging quality and performance.

In addition to the measurements listed under Image Quality Assessment of Still Images, further analysis for video performance includes:

• Temporal Noise
• Spatial and Temporal Noise
• WB Adaptation and Convergence
• Exposure Convergence
• Focusing Time

These additional evaluations provide deeper insights into video imaging system performance, ensuring enhanced stability, responsiveness, and overall video quality.

Precise timing measurements are essential for evaluating imaging system performance. Key parameters include:

• Exposure Time
• Electronic Rolling Shutter
• Frame Rate
• Time Lags
• Autofocus Time Lag
• LED Flickering

Assessing these factors ensures accurate timing, responsiveness, and overall system reliability in various imaging applications.
