Abstract: A distance measurement device includes an imaging optical system, an imaging device, and a distance measurement section which measures based on a plurality of images captured by the imaging device, a distance from the imaging device to the target to be imaged. The imaging optical system includes a polarization beam splitting section which splits a first polarization beam having a first polarization direction and a second polarization beam having a second polarization direction substantially orthogonal to the first polarization direction and allows the polarization beam splitting section to be incident on the imaging device. The imaging device receives the first polarization beam to capture a first polarization image and the second polarization beam to capture a second polarization image. The distance measurement section measures the distance to the target to be imaged on the basis of the first polarization image and the second polarization image.

Abstract: The image display apparatus generates a driving control signal for generating image light on the basis of an image signal, and allows an image projector to generate the image light to form a pixel on a screen in accordance with a modulation timing by performing modulation driving for a light source, and to generate the image light so as to scan the screen while a light emission direction of the image light changes by performing scan driving, allows a gaze-direction detector to detect a gaze direction of a user, and allows a projection-direction driver to change a projection direction of the image light in accordance with the gaze direction. In the first mode, the image display apparatus controls modulation driving and scan driving so that a configuration of a pixel region on the screen changes from a relatively high pixel density region to a relatively low pixel density region.
