Display control apparatus, head mounted display, and display control method
There is provided a display control apparatus capable of displaying a high-quality image while inhibiting a load at the time of displaying the image in front of a user. There is provided a display control apparatus including a signal processing unit that performs signal processing in which a first mode and a second mode are switchable at a first region in a screen and a region other than the first region in the screen, display being performed at a first resolution in the first mode, display being performed at a second resolution in the second mode, in which the signal processing unit performs display while reducing a resolution in the second mode toward an outer periphery of the screen.
1 . A display device, comprising:
a display panel including a plurality of pixels arranged in a matrix;
a controller; and
an eye tracker configured to detect a gaze point of a user, wherein
the controller is configured to determine a first region and a second region on the display panel based on a detection result of the gaze point,
the first region is different from the second region, and
the display panel is configured to:
display first image data with a first resolution in the first region; and
display second image data with a second resolution in the second region, wherein
the second resolution is lower than the first resolution, and
the first region is wider in a horizontal direction than in a vertical direction.
2 . The display device according to claim 1 , wherein the controller is further configured to:
generate the first image data based on first data corresponding to the first region of image data; and
generate the second image data based on second data corresponding to the second region of the image data.
3 . The display device according to claim 2 , wherein the controller is further configured to enlarge the second data to generate the second image data.
4 . The display device according to claim 2 , wherein the controller is further configured to thin out the second data to generate the second image data.
5 . The display device according to claim 1 , wherein the controller further includes a data driver configured to:
select at least one pixel column; and
select at least two pixel columns simultaneously in the second region.
6 . The display device according to claim 5 , wherein the data driver is further configured to supply same data to the at least two pixel columns simultaneously.
7 . The display device according to claim 1 , wherein
the first region is a region which the user focuses on, and
the second region is a region outside the first region.
8 . The display device according to claim 1 , wherein the first region is a region with a FOV (field of view) of 40 degrees.
9 . The display device according to claim 1 , wherein
the controller comprises a gate driver, and
the gate driver is configured to:
select at least one pixel line in the first region; and
select at least two pixel lines simultaneously in the second region.
