A position detection device includes a sensor driving unit driving a touch sensor by providing a drive signal of a sine-wave to the touch sensor and a position detecting unit detecting a position of a touch on the touch sensor. The position detecting unit includes a first detection processing unit performing a touch detection process using an amplitude modulation scheme during a first detection processing period and a second detection processing unit performing the touch detection process using a frequency modulation scheme during a second detection processing period. A position detection method includes a sensor driving step of driving the touch sensor and a position detecting step of detecting the position. The position detecting step includes a first detection processing step of performing the touch detection process using the amplitude modulation scheme and a second detection processing step of performing the touch detection process using the frequency modulation scheme.

The present invention provides a data processing device connected with an intermission driving. The data processing device achieves a satisfactory power saving while ensuring a high level of display quality of the display device. Upon detection of non-data update in a frame buffer, the host calculates a next refreshing timing based on driving information obtained from a liquid crystal display device (LCD), sets a timer for a timeout after a length of time representing the calculated result, and then the host and the LCD shift to Intermission State. Thereafter, when the timer times out to bring the host back to Normal State and a data update at the frame buffer is detected, data for refreshing an display image in the LCD is transferred from the host to the LCD. If the amount of time representing the calculated result is longer than a predetermined baseline, a shift is made to Intermission Statewhich provides greater power saving than Intermission State

Data processing device connected with display device and control method of display device

There is provided a display device that is capable of suppressing occurrence of brightness drop which is caused by refresh of a display image during pause driving. In a normal driving mode, input image data (SsD) according to a continuous tone method is supplied to a source driver () through a data selector () as an image signal (SsD) for driver. On the other hand, in a low-frequency driving mode in which pause driving is performed, the input image data (SsD) is converted into dithered input image data (SsD) by a dithering processing circuit (), and is supplied to the source driver () through the data selector () as the image signal (SsD) for driver. A gradation of the dithered input image data (SsD) is represented in a pseudo manner by an area coverage modulation method by using two values of a maximum value and a minimum value that can be taken as the gradation value of the input image data (SsD).

A stereoscopic image processing device including a depth map generation unit and a depth map correction unit. The depth map generation unit uses a first viewpoint image and a second viewpoint image to acquire depth values in units of blocks constituted of a plurality of pixels and generate a depth map. The depth map correction unit performs a judgment in the depth map as to whether or not a boundary region is included in a block of interest based on depth values of blocks surrounding the block of value, which is a block to be processed, and, if a boundary region is judged to be included in the block of interest, corrects the depth values in units of correction regions, which are units which are smaller than blocks, in the block of interest.

A DPF controller () generates, as image information, a layout identifier (MEN) that specifies the layout of an image to be displayed on a liquid crystal display device (), and an element image identifier (SEN) that specifies the display mode of element images that are being subjected to layout. When an SEN is newly determined and the newly determined SEN is equal to a previously determined SEN, the newly determined SEN is not output to a drawing controller ().

Image information generation device

A DPF controller () easily generates a display identifier and a speech identifier for providing an image and a speech required for driving a mobile body such as an automobile, etc. from state information representing the state of each part of the mobile body. In order to generate a layout identifier (MEN) for specifying a layout of an image to be displayed on a liquid crystal display device (), an element image identifier (SEN) for specifying a display form of an element image in the layout, and a speech identifier of speech data to be output as display identifiers, the DPF controller () matches a MEN/SEN determining table () that stores an identifier table defining a correspondence relation between state information (D) and a MEN, a correspondence relation between the state information (D) and a SEN, a correspondence relation between the MEN and the SEN, and a correspondence relation between the state information (D) and a speech identifier with the state information (D) collected from ECUs (, . . . ) in each part of the mobile body.

An on-vehicle display control unit includes a CPU to which vehicle data of various kinds are inputted and a graphic LSI arranged to generate display data to be outputted to a display. The graphic LSI is arranged to generate predetermined display data from image data generated by a meter ECU. However, if there is a problem in a state of the meter ECU or an input status of 3D moving picture data, the graphic LSI receives a fail safe control from the CPU (), thereby to generate fail safe display data corresponding to the predetermined display data. This realizes an on-vehicle display system capable of stably displaying important vehicle information.

In an image information generation device, based on status information representing statuses of various sections of a mobile unit such as a motor vehicle, image information used to display an image required, for instance, for steering this mobile unit on a display device is generated easily. In order to generate, as the image information, a layout identifier that specifies a layout of an image to be displayed on the liquid crystal display device and a component image identifier that specifies a display mode of each component image in the layout, the DPF controller compares the MEN/SEN judging table that stores an identifier table in which a correlation between the status information and the MEN, a correlation between the status information and the SEN, and a correlation between the MEN and the SEN are defined with the status information collected from the ECUs in the various sections of the mobile unit.
