Abstract:
A filter includes a central filter region, the central filter region to transmit a first wavelength range, a peripheral filter region, the peripheral filter region to block a second wavelength range, and a transition filter region between the central and peripheral filter regions, the transition filter region to transmit or block the second wavelength range differently than the second wavelength range is to be transmitted or blocked in the central and peripheral filter regions. More generally, there may be “N” regions and up to N-1 transition regions.

Abstract:
The present invention discloses a display panel and a pixel structure. The display panel is formed by a repeated arrangement of a plurality of display units, each of them consisting of a 4x4 array or 2x8 array. The present invention improves the uniformity of the spatial sampling by optimizing the arrangement structure of the sub-pixel array in the display panel and the pixel structure, so that the resolution can be improved. Furthermore, the brightness of the display panel is improved with reduced power loss by the addition of a white sub-pixel. In addition, the sub-pixel unit aa or cc is controlled by the same drive circuit, the power loss is further reduced, and the average aperture ratio of the display panel is improved.

Abstract:
The organ imaging apparatus (1) is provided with an image pickup unit (3), a detection unit, and an illumination unit (2). The image pickup unit (3) acquires an image by photographing an imaging object comprising an organ of the living body. The detection unit detects a feature of the imaging object on the basis of the image acquired by the image pickup unit (3). The illumination unit (2) illuminates the imaging object at an angle that exceeds 45 degrees and is not more than 90 degrees with respect to the imaging optical axis (X) of the image pickup unit (3) that passes through the imaging object. The image pickup unit (3) photographs the shadows formed by the imaging object under illumination by the illumination unit (2). The detection unit detects the topography of the imaging object and the border of the organ contained in said imaging object on the basis of the shadows.
