摘要： Provided is a picture conversion method capable of, when displaying a picture obtained from identical video data on a display device at different display luminances, converting the picture so that appearances of the picture visually come close to each other. The method includes a step of converting the picture by setting gradation characteristics when displaying the picture at a second luminance so that an inter-close gradation JND corresponding value difference at the second display luminance comes close to an inter-close gradation JND corresponding value difference at a first display luminance in a target gradation range which is at least part of an entire gradation range.

摘要： Provided is an optical sensor mounting structure which is used in an image display device and in which the gap between a reflection sheet and a tubular cushion for preventing the entry of external light into an optical sensor is eliminated so that the amount of light from a backlight can be measured accurately. A liquid crystal image display device includes an optical sensor that measures light from the back surface of a reflection sheet, a substrate having the optical sensor thereon, and a tubular cushion for preventing the entry of external light into the optical sensor. The front surface of the tubular cushion is bonded to the reflection sheet, and the back surface thereof is bonded to the substrate.

摘要： Provided is a display device and display method that can improve the moving image display performance. A display device includes a display panel and a backlight for the display panel. The display device also includes control means configured to output a control signal for controlling illumination and extinction of the backlight, to the backlight in synchronization with start of update of a frame on the display panel and update means configured to update a frame in each predetermined period in order to change one image displayed on a screen of the display panel. The control means outputs a control signal for controlling the backlight so that the backlight starts to illuminate after the update means starts to update one frame and ends illumination at the time point when the update means starts to update a frame subsequent to the one frame or after the time point.

摘要： Color of a color image may be adjusted by a color adjustment apparatus, image display apparatus, and color adjustment method to enable easier distinction between objects shown in the image. A parameter defines a range of saturation to be adjusted within saturation before color adjustment and a range of change of the saturation after color adjustment compared to the saturation before color adjustment. The color adjustment apparatus calculates the saturation from an image signal, calculates the saturation after color adjustment according to the saturation before color adjustment such that the saturation in the range determined by the parameter increases/decreases by an amount determined by the parameter, and generates an image signal from the saturation after color change. By determining the parameter such that the saturation difference between prescribed colors is greater after color adjustment, the difference in color between a plurality of objects shown in the image is increased.

摘要： Provided is an image conversion method that allows for the representation, on a display, the light and shade of a printed image obtained by printing the image on paper. The image conversion method includes a step of acquiring an illumination-light component and a reflectance component from an input image, a step of correcting the illumination-light component in accordance with display luminance information of a print mode in which the input image is to be printed, so that light and shade of the input image displayed on a display come close to light and shade of a printed image obtained by printing the input image in the print mode, and a step of acquiring a combined image by combining the corrected illumination-light component and the reflectance component or the corrected reflectance component.

摘要： A life prediction method and device that can predict the life of a display device considering the differences between temperatures at measurements of the luminance of the display device. A monitor measures the luminance of the display screen using an optical sensor and measures the temperature around the display screen using a temperature sensor. A terminal device stores the measured luminances and temperatures in such a manner that the luminance and temperature are associated with each other. On the basis of the measured luminances and temperatures obtained by repeated measurements, the terminal device predicts the trend of changes in the luminance assuming that the temperatures at the measurements have been approximately constant, and predicts the life of the monitor on the basis of the predicted change trend.
