Abstract: A luminance correction computation unit 23 corrects a luminance input signal LI, which is inputted into a first luminance adjustment portion 13, to LO based on the semi-transparent mirror luminance correction coefficient b, and the luminance correction computation unit 23 corrects a luminance input signal LI, which is inputted into a second luminance adjustment portion 13, to LO based on the semi-transparent mirror luminance correction coefficient b. As a result, an image of the first image display portion 3, which is reflected by a semi-transparent mirror, and an image of the second image display portion, which is allowed to transmit through the semi-transparent mirror, are corrected in order to cancel a luminance difference according to an optical characteristic of the semi-transparent mirror.

Abstract: A problem is to provide a cursor movement control method by which labor necessary for a movement of a cursor can be reduced and convenience of a user can be improved even when a plurality of screens is displayed on one display device, a computer program, a cursor movement control device, and an image display system. A technical solution is such that a display image creation unit (13) sets a region in a display image corresponding to a display region A to a region a and a region in the display image corresponding to a display region B to a region b, and allocates the regions a and b into the display image. An input unit (12) receives an instruction for whether or not to superposedly display the display region B on the display region A on the display screen (54). A cursor movement control unit (15) controls the movement of the cursor between the region a and the region b according to the received instruction for a superposed display.

Abstract: A rectangular moving region is properly determined. A retainer retains an outputted moving region of time t and, at time t+1, provides it to a specified region feature detector. At time t+1, the specified region feature detector applies the moving coordinates of time t provided by the judgment unit to respective images of times t and t+1 to calculate feature data d(t) around the moving coordinates of time t and feature data d(t+1) around the moving coordinates of time t+1 and then provides the calculated data to a judgment unit. The judgment unit judges whether there is a box, based on the feature data d(t+1).

Abstract: A display light measurement method which can measure color representation of a various types of display devices regardless of the specification of the display device; a computer program, and a measurement system. A measurement device connected to an optical sensor can communicate with a target display device (information terminal) to be measured. The measurement device transmits content including a color patch to the display device to cause the display device to display the content and performs a measurement on the displayed content using the optical sensor. To perform measurements on many color patches, the measurement device repeats the following: when a measurement on one color patch being displayed is complete, the measurement device transmits content including another color patch to the display device to cause the display device to display the content and performs a measurement on the content being displayed.

Abstract: There are provided a display device which can accurately estimate an ambient temperature around the display device, a computer program, a recording medium, and a method for estimating an ambient temperature. A panel temperature sensor and a switch board temperature sensor are disposed in different positions of a display device. A control unit specifies correlation information indicating the correlation between a first temperature difference between a temperature detected by the panel temperature sensor and an ambient temperature and a second temperature difference between a temperature detected by the switch board temperature sensor and the ambient temperature. The control unit estimates the ambient temperature on the basis of the specified correlation information and the temperatures and detected by the panel temperature sensor and the switch board temperature sensor.

Abstract: The present invention relates to a display device that measures display characteristics (such as luminance or chromaticity) associated with a display panel. The display device of the present invention has a light sensor (5) provided at a position allowing outgoing light from a screen (1a) of a liquid crystal panel (1), which serves as the display panel, and extraneous light reflected on the screen (1a) to enter the light sensor (5). Since the light sensor (5) is provided at the position, it is possible to measure the characteristics of the display panel and also the characteristics of the extraneous ambient light reflected on the screen. Thus, it is possible to accurately adjust the display characteristics based on the measurement results.

Abstract: A rectangular moving image region is determined using a simple configuration. When the difference between the representative value of a unit block and the representative value of the same unit block in a comparative frame exceeds a threshold, moving unit block judgment means 5 judges that the unit block is a moving unit block. Moving column block determination means 7 defines a set of unit blocks included in a column including a certain unit block as a column block and, if a column block includes a moving unit block, determines the column block as a moving column block. When a row block includes a moving unit block, moving row block determination means 9 determines the row block as a moving column block. First rectangular moving image region determination means 11 determines, as a rectangular moving image region, a rectangular region specified by unit blocks included in both the moving row block and the moving column block.

Abstract: An anti-aliasing font character on a monitor is prevented from being erroneously judged as an image region. The pixel of interest and four pixels each preceding and following the pixel of interest (a total of nine pixels) are extracted (S3). The largest of the values of the sub-pixels of each of the nine pixels extracted is determined as the representative value of each pixel (step S5). The nine representative values are represented as a histogram and referred to as H0, H1, H2, and the like in the descending order of the frequency in the distribution (S7). Whether Formula (1) below is satisfied is determined (S9). H0+H1+H2<TH . . . (1) If Formula (1) is satisfied, the pixel of interest is judged as a non-character-region pixel; if not, the pixel of interest is judged as a character-region pixel (S11, S13).

The sensor unit 3 moves obliquely forward along slopes 162 formed on front portions of the guide members 16, and a shading member 9 disposed on the sensor unit 3 contacts a display screen 101a of the image display panel. After making a measurement, the sensor unit 3 moves obliquely backward and is stored in the main body frame 2.
