The invention discloses a binocular AR (Augmented Reality) head-mounted device scene depth adjusting method. A mapping relationship between an equivalent center distance dn between a left group of effective display information and a right group of effective display information on an image display source and a distance Ln between a virtual image and a human eye is preset in the head-mounted device; when a user watches the external environment via the head-mounted device, the head-mounted device acquires the distance Dis between a target object and the human eye; Ln is assigned as Dis, an equivalent center distance ds between a left group of effective display information and a right group of effective display information corresponding to the Dis is acquired in a distance mapping relationship delta; and with ds as the equivalent center distance, a to-be-displayed information source image for the virtual information is respectively displayed on the image display source in a left-right mode. Correspondingly, the invention also discloses a binocular AR head-mounted device capable of automatically adjusting the scene depth, virtual information is precisely stacked near a human eye fixation point, the virtual information and the environment are highly integrated, and augmented virtual reality in the true sense is realized.

The invention provides an excellent user interface for setting depth of field in an electronic equipment which can adjust the depth of field by image processing. Therefore, an image device generates a target output image by changing a depth of field of a target input image by image processing. A monitor displays a distance histogram (430) indicating a distribution of distance of the photographed target, wherein the distance histogram is made by mapping the distance of the photographed target at each position in the target input image. Furthermore, the monitor displays strip icon (412) and (413) that are movable along a distance axis (431) in the distance histogram (430). The position of the strip icon (412) and (413) is changed to a desired position of the user by touch panel operation and the depth of field of target input image is changed in accordance with the position of the strip icon (412) and (413)

Traps are produced at color boundaries in a print page that is present in the form of run-length encoded image data, by way of distance mapping. Distances of the run lengths to an adjacent color are determined without decoding the run lengths into a pixel matrix, and the traps are produced on the basis of the distances thus determined. For this purpose, distance vectors are determined for the starting point and for the end point of a run length. The distance vectors are in each case recalculated from the comparison with the distance vectors of adjacent run lengths. The new values of the distance vectors replace the previous values of the distance vectors if the magnitudes of the distances of the new values are less than the magnitudes of the distances of the previous values.
