[Object] To provide an information processing apparatus and a control method that can differentiate between an area that can be visually recognized only by a specified user and an area that can be visually recognized by all users on an information presentation surface that is simultaneously viewed by a plurality of people. [Solution] Provided is an information processing apparatus, including: a line-of-sight detection unit configured to detect lines of sight of a plurality of users with respect to presentation information; and an area determination unit configured to determine, on the basis of the detected lines of sight of the plurality of users, a shared area that is visually recognized by the plurality of users to share information and a confidential area that is not visually recognized by another user to keep information of each user confidential.

An electronic device according to various embodiments may include a display panel, a Display Driving Integrated Circuit (DDIC) operatively coupled to the display panel, and a processor operatively coupled to the DDIC. The DDIC may be configured to receive, from the processor, a signal indicating that a first resolution is to be converted to a second resolution while displaying an image at the first resolution through the display panel, based on a horizontal synchronization signal including a first porch interval, change a length of the porch interval in response to the reception, and display the image at the second resolution through the display panel, based on the horizontal synchronization signal including the porch interval having the changed length.

Disclosed are a display panel, a method of controlling the display panel. The display panel includes multiple pixel groups arranged in an array, wherein each pixel group comprises a first sub-pixel and a second sub-pixel which are adjacently arranged; a plurality of gate lines, wherein the first sub-pixel and the second sub-pixel in a same row of the array are connected to one gate line; a plurality of first data lines, wherein the first sub-pixels in a same column of the array are connected to one first data line; a plurality of second data lines. The second sub-pixels in a same column of the array are connected to one second data line of the plurality of second data lines; the first and the second data lines are spacedly arranged, and a driving component to which the gate lines, the first data lines and the second data lines are connected.

In one example, an image processing device includes a reduction scaler unit that reduces or maintains the image data of an input image. An enlargement scaler unit enlarges or maintains the image data and outputs the image data as the image data of an output image. The reduction scaler unit converts the resolution of the input image to an intermediate resolution in accordance with first image parameters related to an image to be supplied from the enlargement scaler unit, the intermediate resolution being a resolution for performing writing on the memory unit. The enlargement scaler unit converts the intermediate resolution of a memory-held image read from the memory unit to the resolution of the output image, in accordance with second image parameters related to an image to be supplied from the reduction scaler unit.

An approach for providing a user interface having a resolution corresponding to a resolution of a high resolution content is provided. The approach allocates at least one partial frame buffer based on a size and a location of a region on a screen of a display on which a user interface (UI) is displayed. The approach displays the UI based on at least one piece of partial graphic data obtained from the allocated at least one partial frame buffer.

A non-transitory computer-readable recording medium stores an information processing program that causes a computer that constitutes an information processing apparatus including a built-in first display device, to execute a process. The process includes detecting, from outside the information processing apparatus, a state where a second display device is connected, the second display device being different from the first display device; setting both the first display device and the second display device as display destinations, when switching the display destination from the first display device to the second display device; switching the display destination to the second display device after setting both the first display device and the second display device as display destinations; and controlling a display image according to a screen specification of the second display device.

A video signal processing system includes a first video signal processing chip and a second video signal processing chip. The first video signal processing chip determines whether both of a first video signal and a second video signal are in a stable state. After the first video signal processing chip determines that both of the first and second video signals are in the stable state, the first video signal processing chip sends a synchronization signal to the first video processing chip and the second video processing chip. After receiving the synchronization signal, the first video signal processing chip and the second video signal processing chip respectively output a first processed video signal and a second processed video signal to a display device.

A data processing device based on a programmable logic device is described that includes at least one function circuit configured to process input data; and at least one current smoothing circuit, each corresponding to one of the at least one function circuit, and configured to smooth a current change of the programmable logic device caused when a corresponding function circuit is switched between on and off. The current smoothing circuit includes a control circuit configured to generate a driving signal based on a switching manner of the function circuit corresponding to the current smoothing circuit; and a redundant circuit configured to operate according to the driving signal to smooth the current change. The control circuit includes a decoding control word generating circuit and a decoding circuit.

Examples for generating a common video signal for an integrated GPU and the graphical processing device, based on a common display mode setting, are described. In an example, a common display mode setting is determined based on a first set of display mode settings supported by the integrated GPU and a second set of display mode settings supported by the graphical processing device. Based on the common display mode setting, video signals for the integrated GPU and the graphical processing device are generated.
