1. A liquid crystal display, comprising:
a backlight; and a liquid crystal display element, wherein the liquid crystal display performs an image analysis of an image represented by an input image signal and adjusts image quality by performing a control process for the liquid crystal display element and a control process for the backlight based on results of the image analysis; wherein in the image analysis, the liquid crystal display performs
a macro analysis to analyze four factors related to a luminance histogram, a chromaticity histogram, a color histogram, and a spatial frequency histogram of the image represented by the input image signal, and generate the histograms, anda detail analysis to separately analyze a horizontal component and a vertical component of the input image signal and generate horizontal data representing the horizontal component and vertical data representing the vertical component; wherein in the control process for the backlight, the liquid crystal display performs black level detection, white level detection, average picture level detection, and color detection in this order for the image represented by the input image signal based on analysis results of the macro analysis and the detail analysis, and controls the backlight based on results of the detections; and wherein after performing the control process for the backlight, the liquid crystal display performs black level detection, white level detection, average picture level detection, color detection, chromaticity detection, and spatial frequency detection in this order to control the liquid crystal display element. |
