Claim 16:
17. The apparatus according to any one of claim 12, wherein:
the correlation calculator module is further configured to convert each of at least one of two-dimensional arrays of correlation values to a respective sequence of correlation values by replacing each one-dimensional array of correlation values in the two-dimensional array, which one-dimensional array indicates the response of the layer of the retina corresponding to the two-dimensional array to the light stimulus as a function of location in the scanned region of the retina, with a single value that is an average of the correlation values in the one-dimensional array, the sequence of correlation values indicating a response of the layer of the retina in the scanned region to the light stimulus as a function of time; or
in a case where each two-dimensional array of correlation values comprises a sequence of one-dimensional arrays, each of the one-dimensional arrays indicating the response of the respective layer of the retina (10) to the light stimulus as a function of location in the scanned region of the retina, the correlation calculator module is further configured to process each two-dimensional array of correlation values to generate a respective normalised two-dimensional array of correlation values by subtracting the first one-dimensional array in the sequence of one-dimensional arrays from each remaining one-dimensional array in the sequence of one-dimensional arrays, the normalised two-dimensional array of correlation values indicating the response of the corresponding layer of the retina to the light stimulus as a function of location in the scanned region of the retina and time; or
in a case where each two-dimensional array of correlation values comprises an array of one-dimensional arrays, each of the one-dimensional arrays indicating the response of the respective layer of the retina to the light stimulus as a function of location in the scanned region of the retina, the correlation calculator module is further configured to process each two-dimensional array of correlation values to generate a respective normalised two-dimensional array of correlation values by calculating an array of averaged correlation values such that each averaged correlation value in the array of averaged correlation values is an average of the correlation values that are correspondingly located in the one-dimensional arrays, and subtracting the calculated array of averaged correlation values from each of the one-dimensional arrays in the array of one-dimensional arrays, the normalised two-dimensional array of correlation values indicating the response of the corresponding layer of the retina to the light stimulus as a function of location in the scanned region of the retina and time.
