Aspects of the present invention relate to methods and systems for measuring and managing the brightness of digital content in a field of view of a head-worn computer.

An interpolated flat-panel display comprises a display substrate, pixel controllers disposed in a controller array over the display substrate, and pixels disposed in a pixel array over the display substrate. Each pixel controller is connected to one or more control lines and is operable to output pixel information. Each pixel is operable to emit light in response to pixel information received from a pixel controller. The pixel array is larger than the controller array, each pixel is connected to at least one pixel controller, and at least some pixels are interpolated pixels connected to at least two pixel controllers and are operable to emit light in response to pixel information received from the at least two pixel controllers.

Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

A method of projecting a first image and a second image using one multi-wavelength hologram. The first image is different to the second image. The multi-wavelength hologram is arranged for illumination by light of a first wavelength to project the first image. The multi-wavelength hologram is further arranged for illumination by light of a second, shorter wavelength to project the second image.

A signal processing method of a transparent display is disclosed. The signal processing method includes: receiving an input signal; performing a signal conversion step on the input signal to form a converted signal; after performing the signal conversion step, performing a signal identification step based on the converted signal; generating an image signal and a control signal from the input signal and a signal identification result of the signal identification step; outputting the image signal for light emission adjustment of the transparent display; and outputting the control signal for transparency adjustment of the transparent display, wherein a converted gray scale of a pixel is obtained by multiplying at least two gray scales among a red gray scale, a green gray scale, and a blue gray scale of the pixel by previously set corresponding coefficients and summing the multiplied gray scales.
