A display device includes a display panel including a plurality of pixels, a display panel driver, and a zone compensating circuit which divides the display panel into a plurality of unit blocks, obtains load values of input image data for the unit blocks, and generates corrected image data by correcting the input image data based on the load values. Each of the load values corresponds to one of the unit blocks. The display panel driver generates a data signal for displaying an image on the display panel based on the corrected image data. When grayscale values included in the input image data are the same, a luminance of the image displayed on the display panel is decreased moving away from a center of a reference block having a largest load value among the unit blocks based on the corrected image data.

The system further including a composition manager designed to sequence and select what is presented including one or more of data in the field display and the foveal display.

A medical image processing device includes an image processor configured to generate a display image based on a distance between a display device and a target and a size of a display screen in the display device, the display image being displayed on the display device. An image quality of the display image is lowered as the distance becomes larger and the size of the display screen becomes smaller.

A compensation method of a display device includes: sensing a first luminance of the display device when a first pattern is displayed on the display device; calculating a luminance prediction value corresponding to a second pattern to be displayed on the display device based on the first luminance, where the second pattern is different from the first pattern; sensing a second luminance of the display device when the second pattern is displayed on the display device; adjusting a current flowing in a first power line of the display device until the second luminance reaches the luminance prediction value; and storing compensation data corresponding to an adjusted current in a lookup table when the second luminance reaches the luminance prediction value.

An image processing device that generates a second output image signal output to a second liquid crystal panel that is disposed to be superposed on a first liquid crystal panel, includes: a first corrector that generates a gamma correction signal in which a gradation value of an input image signal is corrected; a detector that receives the gamma correction signal and detects an image region brighter than surroundings as a first high-frequency portion from the gamma correction signal; and a second corrector that receives the gamma correction signal and a detection result of the detector and performs correction to decrease the gradation value of the first high-frequency portion in the gamma correction signal. The second output image signal is generated based on the gamma correction signal corrected by the second corrector.

Described herein is a system in which multiple display devices may be located remotely throughout a facility. The system receives location information for a number of users within the facility. The system is able to identify a set of users collocated with a particular display device and generate a set of configuration settings specific to that set of users. Information provided by the system, either in response to an information request or automatically, may be formatted and/or filtered according to the generated set of configuration settings. In some embodiments, the set of configuration settings may be compiled from each of the users in the set of users based on priority.

An embodiment of the process state analysis device of the present invention is provided with an evaluation value calculation unit and a graph creation unit. The evaluation value calculation unit calculates, within an evaluation value calculation range indicating a target range for calculating evaluation values, an evaluation value for each cluster that is classified on the basis of multi-dimensional process data output from each measurement device. The graph creation unit determines a hue for a graph element for each cluster on the basis of the evaluation value for the cluster as calculated within the evaluation value calculation range, and on the basis of a color reference evaluation value corresponding to a reference hue for the graph element, and creates and outputs a graph representing, for each aggregation unit time interval in a specified display period, the number of nodes belonging to each cluster.

Image quality degradation in a display device with two liquid crystal cells is reduced. For this purpose, as an image signal for a liquid crystal display panel in which a display image is generated by light passing through a rear liquid crystal cell and a front liquid crystal cell, an image processing unit generates a rear image signal for the rear liquid crystal cell and a rear image signal for the front liquid crystal cell. This image processing unit includes a gradation value conversion unit that performs a gradation value conversion on an input image signal so as to generate a rear image signal for the rear liquid crystal cell, and a limit processing unit that performs a process of limiting a value of the rear image signal output from the gradation value conversion unit to a predetermined limit value.

An image processing device that generates an output image displayed on a display device that controls a plurality of light sources corresponding to a display region in a nonrectangular shape, the image processing device comprising: a masking processing unit that uses a region other than the display region in an input image, which is input from outside, as a masking processing region to perform masking processing for the masking processing region and generates a masking processed image; a luminance data creation unit that creates luminance data, which indicates luminance of the plurality of light sources when an output image corresponding to the input image is displayed, on a basis of the masking processed image; and an output image creation unit that creates the output image on a basis of the luminance data and the input image or the masking processed image.
