A computer-implemented method, the method comprising: obtaining, at an electronic computing device and for at least one image of a scene rendered in an Augmented Reality (AR) environment, a scene lighting estimation captured at a first time period, the scene lighting estimation including at least a first image measurement associated with the scene; determining, at the electronic computing device, a second image measurement associated with the scene at a second time period, the second time period occurring after the first time period; determining, at the electronic computing device, a function of the first image measurement and the second image measurement; based on the determined function, triggering, at the electronic computing device, calculation of a partial lighting estimation update or triggering calculation of a full lighting estimation update; and rendering, on a screen of the electronic computing device and for the scene, the scene using the partial lighting estimation update or the full lighting estimation update; wherein: the first image measurement and the second image measurement comprise respective first and second ambient light intensity measurements for the scene, and the calculation of the full lighting estimation update is triggered if the determined function is above a predefined threshold and an elapsed time between the first time period and the second time period is above a threshold elapsed time; the function is a ratio of the first ambient light intensity to the second ambient light intensity or a difference between the first ambient light intensity and second ambient light intensity. obtaining, at an electronic computing device and for at least one image of a scene rendered in an Augmented Reality (AR) environment, a scene lighting estimation captured at a first time period, the scene lighting estimation including at least a first image measurement associated with the scene; determining, at the electronic computing device, a second image measurement associated with the scene at a second time period, the second time period occurring after the first time period; determining, at the electronic computing device, a function of the first image measurement and the second image measurement; based on the determined function, triggering, at the electronic computing device, calculation of a partial lighting estimation update or triggering calculation of a full lighting estimation update; and rendering, on a screen of the electronic computing device and for the scene, the scene using the partial lighting estimation update or the full lighting estimation update; wherein: the first image measurement and the second image measurement comprise respective first and second ambient light intensity measurements for the scene, and the calculation of the full lighting estimation update is triggered if the determined function is above a predefined threshold and an elapsed time between the first time period and the second time period is above a threshold elapsed time; the function is a ratio of the first ambient light intensity to the second ambient light intensity or a difference between the first ambient light intensity and second ambient light intensity. the first image measurement and the second image measurement comprise respective first and second ambient light intensity measurements for the scene, and the calculation of the full lighting estimation update is triggered if the determined function is above a predefined threshold and an elapsed time between the first time period and the second time period is above a threshold elapsed time; the function is a ratio of the first ambient light intensity to the second ambient light intensity or a difference between the first ambient light intensity and second ambient light intensity. <EOS>
