A memory control device of the present invention comprises a determination section (34) for determining whether a time point of start of a writing operation falls within a risky period; and a delay control section (32) for delaying, in a case where the determination section (34) determines that the time point of the start of the writing operation falls within the risky period, a time point of the start of one of the writing operation and the reading operation which one is higher in operation rate, said one of the writing operation and the reading operation being delayed by a predetermined delay period.

A display controller of a data processing system fetches data for surfaces to be displayed from memory of the data processing system into a local buffer or buffers of the display controller and provides that data from the local buffer or buffers of the display controller to a display for display. If the display controller determines that data to be provided to the display has not been fetched into a local buffer of the display controller, it provides data that has previously been fetched into the local buffer of the display controller to the display in place of the data that has not been fetched into a local buffer of the display controller.

A display device that achieves both high detection sensitivity of the touch sensor unit and smooth input on the touch sensor unit is provided. A method for driving a display device includes a first period and a second period. The display device includes pixels, a gate driver, and a touch sensor unit. The touch sensor unit detects a touch in the first period and stops detecting a touch in the second period. The gate driver supplies signals to some of the pixels and does not supply signals to the other pixels in the second period.

Digital signage according to an embodiment of the present invention includes: a display unit; a human body sensing sensor unit; and a control unit which controls the operation of the digital signage, wherein the human body sensing sensor unit senses a motion of a human body and the distance between the human body and the digital signage, and the control unit can control so as to divide a frame buffer of content according to a predetermined set value, and to change an arbitrary pixel in a region of the divided frame buffer to black.

An image processing device adapted to perform image processing on image information input, and then output the image information includes a first image processing section adapted to perform image processing on the image information, and include a first storage section to store the image information, and a second image processing section adapted to perform image processing on the image information from the first image processing section, and include a second storage section to store the image information. The first image processing section performs a process of reducing an image size of the image information stored in the first storage section and raising a refresh rate, and the second image processing section performs a process of enlarging an image size of the image information stored in the second storage section.

A method for compressing display data is disclosed. The method comprises performing a wavelet transformation to obtain a general approximation coefficient and a plurality of detail coefficients for a group of pixels; determining whether to prioritise transmission of the general approximation coefficient over transmission of the detail coefficients based on whether there are sufficient resources available to enable a corresponding image frame to be ready for display and/or based on a time since the detail coefficients for a corresponding group of pixels were previously transmitted. If it is determined that transmission of the general approximation coefficient is to be prioritised over transmission of the detail coefficients, the method comprises either: transmitting only the general approximation coefficient, or compressing at least one detail coefficient so as to be more compressed than the general approximation coefficient and transmitting the general approximation coefficient and the at least one compressed detail coefficient.

A display device (2) includes a processor (13) that outputs drawing data and a timing controller (11) that outputs the drawing data input from the processor according to horizontal synchronization and vertical synchronization. When a still image region where drawing data has not been updated compared with a previous frame and a moving image region where drawing data has been updated compared with a previous frame are included in one frame, the processor transmits data update information, which is for specifying the position of the moving image region or a line including the moving image region, to the timing controller temporally earlier than drawing data of the line including the moving image region. The timing controller performs processing for lowering the frame rate of the still image region or processing for thinning out some of image lines of the still image region based on the data update information.

An image processing apparatus includes an input unit inputs a first divided image, an acquisition unit acquires an image of a peripheral region of a first edge of the first divided image from a second image processing apparatus for performing image processing on a second divided image, and also acquires an image of a peripheral region of a second edge of the first divided image from a third image processing apparatus for performing image processing on a third divided image, an image processing unit executes image processing on the first divided image, using the images of the peripheral regions acquired from the second and third image processing apparatuses by the acquisition unit, wherein the image of the peripheral region acquired from the third image processing apparatus includes an image of at least a part of a fourth divided image adjacent to the third divided image.
