An image output device coupled to a first and second signal source and a method thereof. The image output device includes memories configured to store frame image data respectively, a source selection circuit coupled to the first and second signal sources and the memories and configured to choose to store a first frame image data transmitted by the first or second signal source in one of the memories according to a working state of the first signal source, and an image output circuit coupled to the memories and the source selection circuit and configured to output the first frame image data stored in one of the memories. The image output device may rapidly switch to a backup signal source when the signal source is unstable to achieve fast switching and perfect connection.

Image output device and image output method

An image processing device, including an image generation circuit and a multifocal length processing circuit, is provided. The image generation circuit generates multiple depth plane images with depth information and multiple corresponding zoom control information, and merges the multiple depth plane images and the multiple zoom control information according to an arrangement rule, to be a merged image data. The multifocal length processing circuit is configured to decompose the merged image data to restore the multiple depth plane images and the corresponding multiple zoom control information according to the arrangement rule, and to determine a time at which the restored multiple depth plane images are transmitted to a display device and a time at which the restored multiple zoom control information are transmitted to a zoom lens according to a frame rate of the display device. The disclosure also provides an image processing method and a 3D image generation system.

Image processing device, image processing method and 3D image generation system

A projector and a projection method are provided. The projector is coupled to a display card and includes a light source, a light valve, a projection lens, and a processor. The light source provides an illumination beam. The light valve converts the illumination beam into an image beam. The projection lens projects the image beam to the outside of the projector to form an imaged image. The processor receives an input image signal from the display card, and generates a control signal corresponding to the input image signal according to a refresh rate of the input image signal. When the refresh rate is greater than a threshold, the imaged image has a first resolution. When the refresh rate is less than the threshold, the light valve performs a pixel shifting operation, so that the imaged image has a second resolution. The first resolution is less than the second resolution.
