Image pick-up device

An image pick-up device with an electronic image sensor (IS1, IS2) is described, which comprises a matrix of sensor elements (SE) and a low-pass filter for suppressing image frequencies exceeding the sampling frequency of the sensor. The low-pass filter has a first, composite filter function (Fcom)...

Zusammenfassung:	An image pick-up device with an electronic image sensor (IS1, IS2) is described, which comprises a matrix of sensor elements (SE) and a low-pass filter for suppressing image frequencies exceeding the sampling frequency of the sensor. The low-pass filter has a first, composite filter function (Fcom) consisting of a variable component and a constant component and the device has a second filter function (Fc) in conformity with the constant component which is optically or electronically subtracted from the first filter function.
