An image processing device includes a background luminance input unit, an image processing unit and a luminance setting unit. The background luminance input unit stores background luminance information regarding background luminance. The image processing unit generates display image data and contrast conversion information. The display image data is provided by modulating a contrast of a correction image data so that pixel values included in the correction image data are in an acceptable range. The correction image data is provided by correcting blurring in an input image data to be input to the image processing unit based on the background luminance information. The contrast conversion information is information used for modulating the contrast. The luminance setting unit generates a luminance setting information to set a luminance of the projection unit based on the modulation information.

Examples described herein include systems, devices, and methods for backscattering carrier signals in accordance with pixel values of an image and/or video. Signals having a property proportionate to pixel values may be converted into a pulse-containing waveform having pulses whose widths and/or duty cycles are determined based on the pixel values. Backscatter transmitters may backscatter a carrier signal in accordance with the pulse-containing waveform to provide the pixel values to a receiver. In this manner, video transmission at low power and/or battery-free operation may be provided.
