1. Method of forming a combined image based on a plurality of image frames, including:

  • obtaining a first set (18;

    30;

    47;

    64) of at least one array of intensity values for representing an image frame at a resolution corresponding to the number of intensity values in the array, and obtaining a second set (19;

    31;

    46;

    61) of at least one array of intensity values for representing an image frame at a resolution corresponding to the number of intensity values in the array,wherein the combined image is represented by a final array (20;

    42;

    54;

    71) of intensity values,wherein at least some of the intensity values in the final array (20;

    42;

    54;

    71) are each obtained by executing a step (29;

    41;

    57;

    70) of summing an intensity value from each of at least one array (27;

    39;

    56;

    69) of intensity values based on at least one array of intensity values in only the first set (18;

    30;

    47;

    64) and an intensity value from each of at least one array (19;

    40;

    46;

    61) of intensity values based on at least one array of intensity values in only the second set (19;

    31;

    46;

    61), wherein, prior to executing the summing step (29;

    41;

    57;

    70), only the intensity values of the arrays in the first set (18;

    30;

    47;

    64) are mapped from a scale within a first range to a scale within a second range.
