  • Publication number: 20210006768
    Abstract: The invention provides a three-dimensional (3D) image processing circuit and a synchronization signal correction method thereof. The 3D image processing circuit is adapted to process a 3D image signal. The 3D image signal includes an image synchronization signal and a view switching signal. The 3D image processing circuit includes a synchronization signal correction circuit coupled to the image processing circuit. A synchronization circuit of the synchronization signal correction circuit receives an image synchronization signal processed by the image processing circuit and simultaneously receives the view switching signal. The synchronization circuit compares the processed image synchronization signal with the view switching signal, so as to output a view switching signal synchronized with the processed image synchronization signal. The invention further provides an image display device including the above 3D image processing circuit.

  • Patent number: 9482933
    Abstract: A projection apparatus and a method for protecting the projection apparatus are provided. The projection apparatus includes a light source module, a light source control module, and an optical engine module. The light source module includes a light source and light conversion unit. The light source emits an illumination beam, and the light conversion unit converts the illumination beam into a plurality of color beams with different colors. The light source control module includes a light sensing unit and a control unit. The light sensing unit senses light intensities of the color beams, and the control unit determines whether to turn off the light source according to at least one of a light intensity proportion of the color beams and a sum of the light intensities of the color beams. The optical engine module receives the color beams to generate an image beam.
