1. An apparatus, comprising: at least one processor; at least one memory including computer program code, the memory and the computer program code configured to, working with the processor, cause the apparatus to perform at least the following: determine an image histogram associated with an image; determine a linear representation of the image histogram based, at least in part, on the image histogram such that values that correspond to positions of the image histogram are represented at corresponding positions along a span dimension of the linear representation of the image histogram, and such that a dimension of the linear representation of the image histogram at a position on the representation of the image histogram is independent of a value of the image histogram that correlates to the position, the dimension being perpendicular to a span dimension of the linear representation of the image histogram; and cause display of the linear representation of the image histogram and, at least part of, the image.
