The present disclosure performs automatic vision correction according to the usage scenes and the cognition custom of the user, which reduces user operation and improves the user experience.

An image processing apparatus according to the present invention, includes: an input unit configured to receive a predetermined user operation for an image displayed on a display; a change unit configured to perform control of increasing a display range of the display in a case where the predetermined user operation is received by the input unit; a processing unit configured to perform gradation conversion on the image to improve gradation of a high brightness portion, based on the display range increased by the change unit; and a control unit configured to perform control of enabling the increase in the display range in accordance with the predetermined user operation in a case where the image satisfies a predetermined condition and disabling the increase in the display range in accordance with the predetermined user operation in a case where the image does not satisfy the predetermined condition.

A display apparatus may comprise: a panel driving unit comprising driving circuitry, a display panel, and a processor configured to control the panel driving unit, wherein the processor is configured to: control the panel driving unit to output gate signals to multiple gate lines sequentially one by one to process image data at a first driving frequency in a first mode, and control the panel driving unit to output gate signals to the multiple gate lines sequentially at least two gate lines at a time to process image data at a second driving frequency higher than the first driving frequency in a second mode.

The present disclosure generally relates to displaying and editing image with depth information. Image data associated with an image includes depth information associated with a subject. In response to a request to display the image, a first modified image is displayed. Displaying the first modified image includes displaying, based on the depth information, a first level of simulated lighting on a first portion of the subject and a second level of simulated lighting on a second portion of the subject. After displaying the first modified image, a second modified image is displayed. Displaying the second modified image includes displaying, based on the depth information, a third level of simulated lighting on the first portion of the subject and a fourth level of simulated lighting on the second portion of the subject.

Described are various embodiments of an electronic device for a user having reduced visual acuity to fine tune a prescription thereof corresponding with their reduced visual acuity. The device comprises a digital light-field display, a hardware processor; and a non-transitory computer-readable medium having statements and instructions stored thereon for execution by said hardware processor in correcting an output image to be rendered by said digital light-field display in accordance with an image pre-filtering function, wherein said image pre-filtering function receives as input a light-field display optics parameter and a progressively adjustable vision correction parameter that corresponds to vision correction prescriptions.

A display device includes a timing controller and a display. The timing controller is connected to a connector of a USB cable and receive image signals from a host through the USB cable. The display receives the image signals from the timing controller to display an image. The timing controller includes an interface controller, a control signal selector, a data transmitter, and a data processor. The interface controller outputs control signals to control an output order of the image signals. The control signal selector selects and outputs a control signal corresponding to a connection position of the connector from the interface controller. The data transmitter determines the output order of the image signals from the host based on the control signal from the control signal selector. The data processor receives the image signal from the data transmitter and provides the image signal to the display.

A method of driving a display device includes displaying both a natural image and a color vision test image on the display unit. The color vision test image is an image used to determine whether a person has a color vision impairment. A color adjustment user interface for adjusting color of the display unit is displayed on the display unit. A color adjustment instruction that instructs to adjust color of the display unit is received via an input unit. Supply image data supplied to the display unit is adjusted based on the color adjustment instruction by using a controller.

An on-board vehicle navigation system (NAV system) may provide a variety of information and may be integrated with a variety of on-board vehicle systems or features. The NAV system may have the display set to show information about a single system in a full screen mode or have the display divided to show information about multiple systems simultaneously (mixed display mode). The NAV system may allow the user to select an automatic switching from a mixed display mode to a full display mode upon the occurrence of predetermined system conditions. The full display mode may be temporary and automatically return back to the previous display mode or may require a user acknowledgement prior to returning back to the previous display mode. The switch to the full display mode allows more information to be communicated to the user.
