Contrast Sensitivity Function

KyberVision's "CSF" App offers a quick and efficient way to assess the Contrast Sensitivity Function through an adjustment procedure on iPhone, iPod touch or iPad. A full CSF can be obtained in just a couple of minutes and fitted with a standard model to derive the descriptive parameters of the CSF: peak frequency, peak sensitivity, bandwidth, cut-off frequency and DC attenuation.Contrast thresholds are simply measured by adjusting a contrast slider until the stimulus is barely visible. This process is repeated a number of times for a range of spatial frequencies.*** Full-Featured Contrast Sensitivity Testing ***KyberVision's "CSF" App features:- a variety of customizable visual stimuli (grating, Gabor, static or drifting)- multiple stimulus configurations- remote control mode (when installed on a secondary iOS device) through WiFi or Bluetooth- enhanced contrast resolution- Gamma calibration- automatic viewing distance monitoring using the front-facing camera- data fitting- data & subjects management- data export through email, PDF, database backup*** About KyberVision ***We are a company that provides Consulting, Research and Development services in the field of VISION SCIENCES.
