To prevent this, a touch input system in which a cover for preventing incorrect touch is provided over a touch panel to reduce incorrect operations is provided. However, since there is a region that is hard to touch using the cover, electronic devices including such touch panels are not sufficiently widely used. Thus, novel touch panels are provided outside a display region where the cover is provided. The touch panels have a function of selecting first and second regions. The first and second regions intersect with each other to provide a third region. A display object displayed in a region overlapping with the third region is configured to be extracted and executed.

  • Patent number: 10460422
    Abstract: The polarization imaging unit generates a polarized image including pixels for each of a plurality of polarization components. The demosaicing unit calculates a pixel signal for each polarization component by using the pixel signal of the target pixel of the polarized image and the pixel signal of the pixel for each of the identical polarization components located near the target pixel. In one example, a low frequency component is calculated for each polarization component using the pixel signal of the pixel located near the target pixel for each of the identical polarization components. In addition, component information indicating relationship between the low frequency component of the polarization component of the polarized image and the pixel signal of the target pixel is acquired. Furthermore, the pixel signal for each polarization component in the target pixel is calculated based on the low frequency component and the component information for each polarization component.

  • Patent number: 10444500
    Abstract: A projection screen of a head-up display has a projection surface and a back surface opposite to the projection surface. The projection surface is used for receiving an image beam projected by an image projection component and reflecting part of the image beam. The projection screen includes a photochromic layer disposed on the transmission path of the image beam. When an ambient light irradiates the back surface of the projection screen, the transmittance of the photochromic layer decreases as the intensity of the ambient light increases.
