1. A head wearable display system comprising:
a target object detection module receiving multiple image pixels of a first portion and a second portion of a target object, and the corresponding depths;
a first light emitter emitting multiple first-eye light signals to display a first-eye virtual image of the first portion and the second portion of the target object for a viewer;
a first light direction modifier for respectively varying a light direction of each of the multiple first-eye light signals emitted from the first light emitter;
a first collimator, disposed between the first light emitter and the first light direction modifier, to adjust a beam waist location of each of the multiple first-eye light signals so that the multiple first-eye light signals are separable from each other;
a first combiner, for redirecting and converging the multiple first-eye light signals towards a first eye of the viewer; and
wherein the first-eye virtual image of the first portion of the target object in a first field of view has a greater number of the multiple first-eye light signals per degree than that of the first-eye virtual image of the second portion of the target object in a second field of view,
wherein the multiple first-eye light signals are separable from each other if a spatial distance between centers of any two adjacent first-eye light signals on a cross-sectional plane of light path is larger than half of a greatest diameter of the two adjacent first-eye light signals.
