In an embodiment, a method (100) is described. The method comprises receiving (102) data corresponding to an ambient-corrected image of a subject illuminated by an illumination unit (206) providing temporally modulated illumination with a modulation frequency that is higher than a frame acquisition rate used by an imaging device (204) to obtain a set of images having a different spatial intensity modulation pattern in each image. The ambient-corrected image is constructed from the obtained set of images. The method (100) further comprises determining (104) a signal-to-noise ratio, SNR, of at least a portion of the ambient-corrected image. In response to determining that the SNR is below a target SNR, the method causes (106) an indication of an illumination parameter to be sent to the illumination unit to increase an amplitude modulation depth of the temporally modulated illumination used to illuminate the subject while the imaging device acquires a subsequent set of images for constructing a subsequent ambient-corrected image.
