Claim 9:
10. The apparatus according to any one of claim 4, wherein
the two-dimensional array of correlation values comprises an array of one-dimensional arrays of correlation values each indicating the response of the retina to the light stimulus as a function of location in the scanned region of the retina, in which case the correlation calculator module is further configured to convert the two-dimensional array of correlation values to a sequence of correlation values by replacing each of the one-dimensional arrays of correlation values in the two-dimensional array with a single respective value that is an average of the correlation values in the one-dimensional array, the sequence of correlation values indicating a response of the scanned region of the retina to the light stimulus as a function of time; or
the two-dimensional array of correlation values comprises a sequence of one-dimensional arrays each indicating the response of the retina to the light stimulus as a function of location in the scanned region of the retina, in which case the correlation calculator module is further configured to generate a 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 retina to the light stimulus as a function of location in the scanned region of the retina and time; or
the two-dimensional array of correlation values comprises an array of one-dimensional arrays each indicating the response of the retina to the light stimulus as a function of location in the scanned region of the retina, in which case the correlation calculator module is further configured to generate a 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 retina to the light stimulus as a function of location in the scanned region of the retina and time; or
the two-dimensional array of correlation values comprises an array of one-dimensional arrays each indicating the response of the retina to the light stimulus as a function of location in the scanned region of the retina, in which case the correlation calculator module is further configured to convert the two-dimensional array of correlation values to a sequence of correlation values by replacing each of the one-dimensional arrays of correlation values in the two-dimensional array with a single respective value that is an average of the correlation values in the one-dimensional array, the sequence of correlation values indicating a response of the scanned region of the retina to the light stimulus as a function of time.
