Abstract: A holographic display device includes a display panel for emitting a first image light and a diffraction component on an optical path of the first image light. The first image light includes first and second colors of light. The diffraction component diffracts the first color light at a first diffraction efficiency and diffracts the second color light at a second diffraction efficiency.

By emitting the first color light and the second color light in the first image light at the same grayscale value, a ratio of intensities of the first color light and the second color light becomes inversely proportional to a ratio of the first diffraction efficiency and the second diffraction efficiency.

Abstract: A method to fuse images to create temperature-based images with higher resolution and frame rate than those of a microbolometer controls a first camera device to capture a first video and controls an infrared camera device to capture a second video. Information as to objects in each frame of image in the first video is recognized, and the edge of an object in the image information is extracted. A thermal image corresponding to the first video is obtained from the second video, the thermal image being processed by an MEMC algorithm for motion estimation and compensation (prediction), to obtain an image free of misalignments and time displacements. A final fused image is obtained by fusing the defined-edges image, the thermal image, and the prediction image. An electronic device employing the method is also disclosed.

Abstract: A packaging structure for an image sensor includes a circuit board, an image sensor, a first installation bracket, and a second installation bracket. The image sensor is fixed on the circuit board via a first adhesive layer with high viscosity. The first installation bracket is fixed on the image sensor via a second adhesive layer with less (lower) viscosity.
