In statistics, a histogram is a graphical representation of the distribution of data. It is an estimate of the probability distribution of a continuous variable and was first introduced by Karl Pearson. A histogram is a representation of tabulated frequencies, shown as adjacent rectangles or squares (in some situations), erected over discrete inte...

(Digital cameras and photo printers) A graph that shows the brightness distribution (by depicting the distribution of dark and bright pixels) for a scene. The data can be used to judge the exposure of the picture. Histograms are sometimes found in high-end digital cameras.

A graphical display showing the distribution of data values in a sample by dividing the range of the data into non-overlapping intervals and counting the number of values which fall into each interval. These counts are called frequencies. Bars are plotted with height proportional to the frequencies. See also: Cumulative Frequency, Relative Frequenc...

A histogram is a bar graph analysis tool that is used to identify contrast and dynamic range of any image. Histograms are found in the more advanced digi-cams and software programs (graphic editors), such as Adobe Photoshop 7, CS or Elements, and are used to manipulate images. The histogram shows a scale of 0 - 255 (left to right) with 0 being bl.....
