INRICHTING VOOR HET VERWERKEN VAN SIGNALEN ZOALS TEWEEGGEBRACHT DOOR EEN BEELDSENSOR ALS GEVOLG VAN FOTOBEKRACHTIGING VAN DE BEELDONTVANGENDE PLAATSEN VAN ZULK EEN SENSOR, TENEINDE STORENDE EFFEKTEN VAN DEFECTE SENSORELEMENTEN TE VERMINDEREN.

摘要

There is produced for each location of an image sensor, such as an X, Y addressed photodiode array or a self-scanned charge transfer array, a signal indicative of the dark current amplitude at that location. During operation of the sensor, when a location producing excessive dark current is read out, rather than using the signal stored at that location, there is instead substituted a signal level which is the average of that stored in adjacent locations of the sensor.
