Abstract: A porous aluminum electrode has a porous layer formed by sintering aluminum powder on the surface of an aluminum core. The porous aluminum electrode, when subjected to a formation to a voltage of 200V or more, is boiled and then subjected to a first forming process in which formation is performed in an aqueous solution of ammonium adipate at a temperature of 80° C. or below and a second forming process in which formation is performed in a boric acid aqueous solution. When heat depolarization is first carried out, washing with water is performed for five minutes or more before heat depolarization; therefore, the porous layer is not destroyed.

Abstract: 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.

Abstract: 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.

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: Provided is a display control apparatus including a detection unit configured to detect a user operation, and a window control unit configured to display a plurality of application windows on a screen, and control display of each application window based on the user operation detected by the detection unit. If it is determined that it is difficult to identify a first application window associated with a first application due to at least a portion of the first application window being hidden by a second application window, the window control unit is configured to control display of the first application window so that identification information for identifying the first application is visible to a user.

Abstract: This invention provides an aluminum electrode plate for an electrolytic capacitor, which, even when the thickness of an etching layer is large, can realize a high level of impregnation of a solid electrolyte and can reduce ESR of a capacitor. An aluminum plate having an aluminum purity of not less than 99.98% by mass is etched to form an etching layer having a depth of 70 ?m or above. When a plane cross section of a position deeper than 20 ?m from the surface in the etching layer is measured with an image analyzer, for each measured face, not less than 70% of the total number of pits within the measured face is accounted for by pits having a diameter of 0.01 to 1 ?m ?; in terms of equivalent circle diameter. The aluminum plate has an aluminum purity of not less than 99.98% by mass and comprises 5 to 50 ppm of Fe and 5 to 40 ppm of Cu with the balance consisting of inevitable impurities.
