A camera includes an image sensor having a first recording channel of a first sensitivity for recording first image data including first pixels and a second recording channel of a second sensitivity lower than the first sensitivity for recording second image data including second pixels. The first pixels and second pixels are associated with one another by capturing a same object area. A control and evaluation unit processing the image data is configured to suppress noise effects in the second image data using a noise suppression filter that assigns a new value to a respective considered second pixel based on second pixels in a neighborhood of the considered second pixel. The noise suppression filter takes the second pixels in the neighborhood into account with a weighting that depends on how similar first pixels associated with the second pixels are to the associated first pixel of the respective considered second pixel.
A camera comprising
A method for acquiring first image data including first pixels in a first recording channel of a first sensitivity of an image sensor and for acquiring second image data including second pixels in a second recording channel of a second sensitivity smaller than the first sensitivity of the image sensor,
