Formulas to find Kell Factor

Horizontal Lines Lost

Horizontal lines lost is defined as the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.

Symbol: L_h

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Horizontal Lines Lost

Number of Lines in Frame

Number of Lines in Frame refers to the total number of horizontal lines that make up a complete frame of a video signal.

Symbol: N_L

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Number of Lines in Frame

Other formulas in Resolution Parameters category

Go Number of Lines in Frame

N L = \frac{f hzl}{FPS}

Go Number of Frames Per Sec

FPS = \frac{f hzl}{N L}

Go Number of Horizontal Lines Lost during Vertical Retrace

L h = \frac{VRT}{T h}

Go Vertical Retrace Time

VRT = L h \cdot T h

How to Evaluate Kell Factor or Resolution Factor?

Kell Factor or Resolution Factor evaluator uses Kell Factor = Horizontal Lines Lost/Number of Lines in Frame to evaluate the Kell Factor, The Kell factor or resolution factor formula is defined as a parameter used to limit the bandwidth of a sampled image signal to avoid the appearance of beat frequency patterns when displaying the image in a discrete display device, usually taken to be 0.7. Kell Factor is denoted by KF symbol.

How to evaluate Kell Factor or Resolution Factor using this online evaluator? To use this online evaluator for Kell Factor or Resolution Factor, enter Horizontal Lines Lost (L_h) & Number of Lines in Frame (N_L) and hit the calculate button.

FAQs on Kell Factor or Resolution Factor
