1. Wearable display comprising: first and second imaging units disposed in a housing, the first and second imaging units having a predetermined horizontal distance therebetween; optical members that guide image light beams to the first and second imaging units; a sensor that detects angular acceleration or acceleration acting on the housing; an image processor configured to process image signals produced by the first and second imaging units and operate on the image signals so as to produce corrected image signals in accordance with the angular acceleration or the acceleration detected by the sensor when the angular acceleration or the acceleration is less than a predetermined threshold; and first and second displays with a horizontal distance therebetween disposed in the housing, the first and second displays configured to display the corrected image signals processed by the image processor, wherein for a frame period in which the angular acceleration or the acceleration is greater than the predetermined threshold, the image processor is further configured to select from memory and for display on the first and second display for the frame period images previously captured by the first and second imaging units.
