摘要： An image processing device configured to synthesize a first image and a second image shot in two or more exposure times different in length in a parallel way within one frame time, includes: a level adjuster configured to adjust the first image and output a corrected first image having a luminance level substantially aligned with a luminance level of the second image; a movement detector configured to calculate absolute values of differences between positionally corresponding pixel pairs in the corrected first image and the second image and accumulate the calculated absolute value on an image block basis to obtain a movement detection amount on the image block basis; a movement blending ratio calculator configured to smoothen the amounts of detected movement and calculate a movement blending ratio between positionally corresponding pixel pairs based on the smoothened amounts of detected movement; and an image synthesizer configured to generate a movement-adaptive image by synthesizing pixels at the corresponding positions at the movement blending ratio.

摘要： A display apparatus includes a first mirror and a half mirror between a display device and a concave mirror. The first mirror reflects emission light emitted from an elongate display surface of the display device, toward the half mirror. The half mirror reflects the light reflected by the first mirror, toward the concave mirror. The concave mirror reflects the light reflected by the half mirror, toward the half mirror. In a top view of the display apparatus, a line passing through a center of the display surface in a longitudinal direction and parallel to the longitudinal direction and a tangent line passing through a center of a reflection surface of the concave mirror in a longitudinal direction and parallel to the longitudinal direction intersect at a predetermined angle.

摘要： An image processor includes: an image sensor which outputs a short exposure image and a long exposure image; a sensor controller which controls first and second exposure sensitivities; a motion blending ratio calculator which calculates a motion blending ratio based on a motion amount of a subject; a motion-adapted image synthesizer which generates a motion-adapted image based on the motion blending ratio; and an HDR image synthesizer which synthesizes the motion-adapted image and the short exposure image, to generate an HDR image. The sensor controller controls the first exposure sensitivity: so that the first exposure time changes from increasing to constant and the first sensor gain changes from constant to increasing, when the brightness of the subject decreases from a first subject brightness; and so that the first exposure time changes to increasing and the first sensor gain changes to constant, when the brightness decreases from a second subject brightness.

摘要： An image processor includes: an image sensor outputting a short exposure image and a long exposure image; a sensor controller that, when brightness of the subject changes, controls first exposure sensitivity to cause the short exposure image to have first brightness and controls second exposure sensitivity to cause the long exposure image to have second brightness; a motion blending ratio calculator calculating a motion blending ratio based on a motion amount of the subject; a motion-adapted image synthesizer generating a motion-adapted image by synthesizing a corrected short exposure image and the long exposure image based on the motion blending ratio; and an HDR image synthesizer generating an HDR image by synthesizing the motion-adapted image and the short exposure image together. When the subject becomes darker, the sensor controller controls the first and second exposure sensitivities to cause the first sensor gain to be at most the second sensor gain.

摘要： The present application discloses an information device for performing optical information processes for a recording medium including a phase-change recording layer which becomes amorphous under irradiation with pulsed amorphization light that has prescribed amorphization energy Ew. The information device includes an irradiator configured to irradiate a prescribed region of the phase-change recording layer with pulsed light and an energy setting portion which sets crystallization energy Ee for the pulsed light to crystallize the prescribed region. The crystallization energy Ee per the pulsed light, which is set by the energy setting portion, is greater than the amorphization energy Ew per the pulsed amorphization light.
