Methods and systems for content resolution adjustment for passive display devices are described herein. Passive display devices such as a passive magnifying device (e.g., a screen magnifier) or a projector (e.g., a built-in mobile phone projector) are useful in enlarging photos, documents, videos, etc. for view for small-sized small-screen device screens. However, optimal content resolution for the small-screen device screens may not be optimal for the passive display devices. Particularly, when a small-screen device receives content from a remote computing device, the initial content resolution may not be optimal even for the small-screen device screen because of low transmission speed and/or low bandwidth of a connection with an original data source. Content resolution adjustment is provided in this disclosure by determining distance between the passive display device and the small-screen device, calculating magnification ratio for the passive display device, and adjusting the content resolution based on the calculated magnification ratio.

An image processing method and device are disclosed. The method is applicable to an image processing device having an operating system, and the method includes: receiving, by an image processing module of the operating system, an instruction of a first application program to call the image processing module of the operating system, where the instruction carries a to-be-displayed image and a resolution of the to-be-displayed image; and when the resolution of the to-be-displayed image is less than a first threshold, performing, by the image processing module, super-resolution processing on the to-be-displayed image, and displaying an image obtained after the super-resolution processing, to resolve a problem of a low image definition in a conventional display method.

A method for operating as electronic apparatus includes displaying, by a display apparatus, a first image based on first image data transmitted from a first terminal apparatus to the electronic apparatus in a first area of a surface and changing, by the first terminal apparatus the amount of the first image data transmitted by the first terminal apparatus per unit time period to the electronic apparatus in accordance with a change instruction to change the size of the first area.

A system for reducing bandwidth and/or reducing power consumed by a display may comprise a display having a background plane and a region of interest plane that may be identified by a gaze tracker. The region of interest may be of a higher quality picture. In some embodiments, the display may be a large panel display and in others a head mounted display (HMD).

A method and a device for displaying non-standard resolution data are provided. The method includes: reading signal source data and determining whether the signal source data is standard resolution data; in a case that the signal source data is non-standard resolution data, determining whether the non-standard resolution data is already stored in a memory; in a case that the non-standard resolution data is already stored in the memory, displaying the non-standard resolution data; and in a case that the non-standard resolution data is not stored in the memory, storing the non-standard resolution data in the memory and displaying the non-standard resolution data.

An electronic apparatus includes a display and a processor for controlling the display. In response to the electronic apparatus operating in a first operating mode, the processor displays a content screen including a background image layer with a rear background image of the electronic apparatus and an object layer with a graphic object in the display. In response to receiving a convert command to convert to a second operating mode, the processor decreases a resolution of the content screen displayed in the display and adds a content layer including a content image enlarged gradually from a region of the content screen to the an entirety of the content screen.
