Displaying a histogram
A histogram is a graph showing the brightness of an image. The horizontal axis shows the brightness, and the vertical axis shows the number of pixels. The graph display indicates a dark image when skewed to the left side, and a bright image when skewed to the right side. The histogram is a useful reference for checking the exposure during recording and playback when the LCD screen is hard to be seen.
