Sensor device for camera, determines intensity gradient in portion of radiant field incident at deflextion position based on output signal of sensing element

摘要

The device (10) has sensor arrangement (12) comprising sensing element (14) which provides output signal based on the intensity of portion of radiation field (L). A positional shift device (20-1) displaces the sensor arrangement between first and second deflexion positions. Intensity gradient in portion of radiant field incident at the second deflextion position is determined based on the output signal. Independent claims are included for the following: (1) method for determining local intensity gradients; (2) computer program for determining local intensity gradients; and (3) memory device.
