A short discussion on high resolution cameras

VICON A&E SUMMIT ‘09

A Short Discussion on High Resolution Cameras


Goals

  • Understand new terms and technology

  • Discuss megapixel camera benefits

  • Discuss megapixel camera trade-offs

  • Overview of new Vicon products

  • Look at possible product applications

Goals


Mega terms

Pixel PICture ELement

Pixel count, expressed as megapixels

Pixels Per Foot

Progressive scan

Mega Terms


Megapixel cameras

Megapixel Cameras

  • Four Major Benefits

    • Higher definition = greater detail

    • More coverage with fewer cameras

    • Different aspect ratio = higher efficiency

    • Progressive scan = stable picture


Higher definition greater detail

Live Viewing

After the Fact

Multi Views

Higher Definition = Greater Detail


Fewer cameras with greater detail

Fewer Cameras with Greater Detail


Fewer cameras with more detail

Fewer Cameras with More Detail


Resolution relationship

1289 X 1024 VGA 1.3 MP

Resolution Relationship

720 X 480 VGA


Different aspect ratio higher efficiency

  • Record the picture that is needed

Different Aspect Ratio = Higher Efficiency


A short discussion on high resolution cameras

Interlaced Scan vs. Progressive Scan

  • Interlaced Scan


A short discussion on high resolution cameras

Megapixel Trade-Offs

  • Greater bandwidth and storage requirements

  • Four or more times greater

    • But … a 3 MP camera can replace up to 3 standard cameras


A short discussion on high resolution cameras

Megapixel Trade-Offs

  • Smaller pixels are normally less light sensitive

  • PixelsPicture Element


New camera new lens

  • Lens Quality

  • Optics true to the edges

  • Chip/ Lens Alignment

  • Back focus

New Camera; New Lens


Facts about lenses

Most sellers of mega pixel cameras are selling “pixels” not image quality*

Standard Lenses are made for 489 TV Lines

Lens quality needs to equal camera quality

Facts about lenses

A short discussion on high resolution cameras

Pixels Per Foot: It’s all about the details

  • Two ways to get detail.

    • Get the camera closer

      • Bigger lens / Move the camera

    • Collect more data.

How Many Pixels Are Needed?

Monitoring 20 PPF

Recognition 40 PPF

Identification 60 PPF

Detail 80 PPF
