Abstract
The invention describes an infrared imaging assembly () for capturing an infrared image (M, M) of a scene (S), comprising an infrared-sensitive image sensor (); an irradiator () comprising an array of individually addressable infrared-emitting LEDs, wherein each infrared-emitting LED is arranged to illuminate a scene region (S, . . . , S); a driver () configured to actuate the infrared irradiator () by applying a switching pulse train (T, . . . , T) to each infrared-emitting LED; an image analysis module () configured to analyse a preliminary infrared image (M) to determine the required exposure levels () for each of a plurality of image regions (R, . . . , R); and a pulse train adjusting unit () configured to adjust the duration (L, . . . , L) of a switching pulse train (T, . . . , T) according to the required exposure levels (). The invention also described a method of generating a depth map (D) for a scene (S); a depth map generator comprising an embodiment of the inventive infrared imaging assembly (); and a camera comprising such a depth map generator ().
