Method, performed by an image sensor circuitry (900; 1000) comprising an image sensor, for reduction of laser speckle effects in a digital image resulting from the image sensor sensing laser light reflected from an object as part of laser triangulation performed by a 3D imaging system, wherein the method comprises: per each pixel position (x, y) of at least a subregion of the image sensor: - assigning to said pixel position (x,y) a predefined pixel window (w) comprising said pixel position (x,y) and one or more of its closest neighboring pixel positions, - obtaining first pixel values for each pixel (p w) located within said predefined pixel window (w), said first pixel values resulting from the same exposure and corresponding to sensed light from this exposure, and - combining the obtained first pixel values into a single, second pixel value according to a predefined combination function; wherein the first pixel values and the second pixel values of said pixel positions of said at least subregion of the image sensor are analogue pixel values and said predefined pixel windows (w) assigned to said pixel positions of said at least subregion of the image sensor are one dimensional and oriented in the same direction; and - providing the digital image based on the second pixel values, whereby there is reduction of laser speckle effects in the digital image compared to if the digital image would be based on the first pixel values. per each pixel position (x, y) of at least a subregion of the image sensor: - assigning to said pixel position (x,y) a predefined pixel window (w) comprising said pixel position (x,y) and one or more of its closest neighboring pixel positions, - obtaining first pixel values for each pixel (p w) located within said predefined pixel window (w), said first pixel values resulting from the same exposure and corresponding to sensed light from this exposure, and - combining the obtained first pixel values into a single, second pixel value according to a predefined combination function; - assigning to said pixel position (x,y) a predefined pixel window (w) comprising said pixel position (x,y) and one or more of its closest neighboring pixel positions, - obtaining first pixel values for each pixel (p w) located within said predefined pixel window (w), said first pixel values resulting from the same exposure and corresponding to sensed light from this exposure, and - combining the obtained first pixel values into a single, second pixel value according to a predefined combination function; wherein the first pixel values and the second pixel values of said pixel positions of said at least subregion of the image sensor are analogue pixel values and said predefined pixel windows (w) assigned to said pixel positions of said at least subregion of the image sensor are one dimensional and oriented in the same direction; and - providing the digital image based on the second pixel values, whereby there is reduction of laser speckle effects in the digital image compared to if the digital image would be based on the first pixel values. - providing the digital image based on the second pixel values, whereby there is reduction of laser speckle effects in the digital image compared to if the digital image would be based on the first pixel values.
