Extended Data Fig. 5: Photography of the ColorChecker chart and a white ring using stacked TFT array based camera.

Three semi-transparent arrays with a diode architecture similar to those used in the monolithically stacked architecture were utilised. a. Structure of a perovskite detector integrated with TFT pixel readout b. Photo of 3 mechanically stacked RGB perovskite TFT arrays c. Optical schema of photographic experiment. The D50 illuminant light reflected from a Macbeth ColorChecker chart was focused on the TFT array stack. d-f. B, G, R channel images of the ColorChecker obtained after flat-field correction (Supplementary Fig. 9). g. Combined three-channel colour image. h. The same image after white balance and brightness correction. i) reference photo of the ColorChecker chart. j. Images of a printed white ring on a black background obtained from the R, G, and B channels of the stacked TFT arrays. k. Imitation of CFA mosaics obtained by applying a numerical mask of Bayer pattern on (j). l. Result of demosaicing procedure applied on (k). m. Final colour image obtained from the stacked RGB and CFA sensors. Intensity profiles for both images are shown in brown (left) and purple (right).
