Mobile electronic device

摘要

According to one embodiment, a mobile electronic device includes an image projection unit for projecting an image, an image display unit for displaying an image, and a control unit for controlling the image projection unit and the image display unit. When the image projection unit projects an image and the image display unit displays an image, the control unit performs control for making the chromaticity of the image projected by the image projection unit and the chromaticity of the image displayed by the image display unit match each other.

1. A mobile electronic device, comprising:
a battery; an image projection unit for projecting an image; an image display unit for displaying an image; a control unit for controlling the image projection unit and the image display unit; and a temperature monitoring unit for measuring or for estimating the temperature of a light source of the image projection unit, wherein the control unit performs, when the image projection unit projects an image and the image display unit displays an image, control for making the chromaticity of the image projected by the image projection unit and the chromaticity of the image displayed by the image display unit match each other; when performing control of matching the chromaticity, the control unit acquires temperature information from the temperature monitoring unit, and controls the light source on the basis of the temperature information such that the brightness of the light emitted from the light source is close to reference brightness; the image projection unit projects an image by performing a color-mixing with respect to lights of a plurality of colors, the control unit performs control on the basis of a change rate of brightness caused by change in temperature for each light of the plurality of colors such that brightness of the light emitted from the light source is close to the reference brightness; and the control unit switches the control between performing and not-performing control of making the brightness of each color closer to the reference brightness, in accordance with whether the image projection unit is operating with power supplied from the battery or the image projection unit is operating with power supplied from an external power supply.
