Abstract: An adjustment value holding unit holds an adjustment value selected for displaying medical image data on a medical image display device with a predetermined image quality. An image attribute detector detects an attribute of the medical image data. A determiner determines whether or not the adjustment value held in the adjustment value holding unit matches an adjustment value corresponding to the attribute detected by the image attribute detector. A notification unit visually or audibly notifies that the adjustment value held in the adjustment value holding unit does not match the adjustment value suitable for the medical image to be displayed on the medical image display device, when the determiner determines that the adjustment value held in the adjustment value holding unit does not match the adjustment value corresponding to the attribute detected by the image attribute detector.

Abstract: First and second display drivers drive a display unit to display a first image based on a first image data in a first display region of the display unit, and a second image based on a second image data in a second display region. First and second luminance sensors detect a brightness of an image on the first and second display region, respectively. First luminance adjuster adjusts the luminance of the first image, such that the brightness of an image on the first display region that is to be detected by the first luminance sensor becomes a first sensor luminance value. Second luminance adjuster adjusts the luminance of the second image, such that the brightness of an image on the second display region that is to be detected by the second luminance sensor becomes a second sensor luminance value.

Abstract: A display device, wherein a mounting substrate (21) having a projected part (21b) projected from a part of a base part (21a) toward a display surface (11a) is installed on a frame (12) through a mounting fitting (30), a brightness sensor (22) is installed on the projected part (21b) of the mounting substrate (21), and the distance (z) thereof from the display surface (11a) is reduced to less than 1.75 mm.
