Abstract:
Provided is a display system with which visibility can be improved.
The display system includes an imaging device, a control device, and a display device. The imaging device includes first pixels arranged in a matrix, and the display device includes second pixels arranged in a matrix. The imaging device has a function of generating first image data on the basis of the illuminance of light emitted to the first pixels. The control device has a function of forming a histogram on the basis of the first image data and dividing the histogram into two or more illuminance ranges. The control device has a function of converting the gray levels which are included in the first image data as information and correspond to the illuminance of the light emitted to the first pixels, thereby generating second image data obtained by performing dynamic range compression on the first image data. The compressibility for the dynamic range compression is calculated for each illuminance range by the control device on the basis of the value of integral in each illuminance range of the histogram.
