A method and system for real-time slide displaying of a scanned image. An image conversion supported method for real-time slide displaying of a scanned image, comprising: collecting a scanned image (S410), so as to obtain an incremental image data block; performing incremental data processing (S420), so as to process the incremental image data block according to a state of a current image conversion; adding the incremental image data block to an image cache allocated in a computer memory (S430), the image cache storing image data in a display screen; performing incremental displaying (S440), so as to copy the incremental image data block to a display memory of a display card, and use the display memory of the display card to perform real-time slide displaying on the incremental image data block. When an image conversion request is obtained, an image processing thread is used for processing image data in an image cache so as to obtain image conversion data, and a refresh display request signal is set; and a display refresh thread is used for performing refresh displaying on an image conversion data partition according to the refresh display request signal.

A display device includes a driving controller controlling a data driving circuit and providing a clock signal and a driving voltage in response to an image signal and a control signal received from an external source. The driving controller restores a data enable signal having a display period and a blank period in one frame on the basis of the control signal and sets a voltage level of the driving voltage applied to the gate driving circuit in accordance with a duration of the blank period. During a sequence of frames having a changing frame rate, the driving voltage for each respective frame may be set based on the duration of each respective blank period.

In a case where next image data, corresponding to a next screen, is not supplied from a host even when first predetermined time has elapsed since the first supply of image data was completed, the period control section (32) starts the second supply of the image data, of which the first supply has been carried out, to a liquid crystal display device. In a case where next image data, corresponding to a next frame, is not supplied from the host even when second predetermined time has elapsed since the second supply of the image data was completed, the period control section (32) starts the third supply of the image data to the liquid crystal display device, and sets the first predetermined time to be longer than the second predetermined time. This makes it possible to appropriately update a displayed image.

A method for controlling output of image data and an electronic device supporting the same are provided. The method includes defining a frame memory by a partial memory area corresponding to a size of image data corresponding to one image frame to be output to a partial area of a display panel or dividing the frame memory into a plurality of memory areas, writing, in the plurality of memory areas, image data corresponding to successive image frames of image content, accessing the plurality of memory areas to read the written image data, and outputting the read image data to the display panel divided into a plurality of panel areas.

The present invention provides a liquid crystal display device capable of suppressing a decrease in display quality when pause drive is performed in an alternating-voltage drive mode, as well as a method for driving the same. In a first drive frame, overshoot drive is performed using correction values provided by an LUT to apply overshoot voltages whose absolute values are higher than absolute values of signal voltages to data signal lines. Subsequently, in a second drive frame, normal drive is performed to write signal voltages of the same polarity as the overshoot drive voltages to the data signal lines. Thereafter, a pause period in which an image written by normal drive is displayed continues until the start of a drive period in the next pause drive period. As a result, a decrease in luminance immediately after the signal voltages are written during the second drive period is suppressed significantly, so that the viewer barely recognizes flicker.

Systems and methods of adjusting a frequency of a graphics controller may include a logic to determine a metric associated with an input/output (I/O) queue. The metric may be used to determine whether an I/O limited condition exists. The I/O limited condition may be associated with a graphics controller. There may be a logic to cause a frequency of the graphics controller to be decreased when the I/O limited condition exists, and a logic to cause the frequency of the graphics controller to be increased when the I/O limited condition does not exist. The I/O limited condition may exist when a magnitude of the metric is equal to or greater than a first threshold. The I/O limited condition may not exist when the magnitude of the metric is equal to or less than a second threshold.

A memory management method for making an area of a buffer in which a reference picture is stored, re-usable for another decoded picture, the method comprising the steps of: marking first information indicating that the reference picture is no longer referred to, to the refrence picture; marking second information indicating that the reference picture is already outputted for display, to the reference picture; and erasing an area of the buffer to make it re-usable, based on the first and second information.

The picture decoding method of the present invention comprises decoding an encoded input picture, judging whether or not the decoded picture is a picture for reference and whether or not the decoded picture is a picture for output which needs to be stored until its display time, and storing, in the picture buffer, the picture for reference and the picture for output based on the determination result.
摘要:
The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPU 12 processes display area acquisition requests from a plurality of processing units R1 - Rn according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit R1 - Rn. Each processing unit R1 - Rn executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit R1 - Rn after each processing unit R1 - Rn sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit R1 - Rn can be controlled appropriately.
