Abstract: A video conference apparatus including an image detection device, a sound source detection device, and a processor and a video conference method are provided. The image detection device obtains a conference image of a conference space. The sound source detection device detects a sound source of the conference space and outputs a positioning signal corresponding to the sound source. The processor receives the conference image and the positioning signal to select a first sub-conference image corresponding to the sound source in the conference image according to the positioning signal. The processor detects a human face image closest to a central axis of the first sub-conference image, selects a second sub-conference image in the conference image by treating the human face image as an image center, and outputs the second sub-conference image. Therefore, an appropriate close-up conference image is automatically generated, so that a favorable video conference experience is provided.

Abstract: A projector, a projection system and an image projection method are provided. The projector includes an image processing circuit, a processor circuit and a memory circuit. The image processing circuit is configured to adjust a first image. The processor circuit is electrically connected to the image processing circuit. The processor circuit is configured to combine the first image with a second image in a first display mode of the projector. The memory circuit is electrically connected to the processor circuit. The memory circuit is configured to store the second image. The projector projects a display image formed by combining the first image and the second image to a projection target.

Abstract: A computer system, a resource arrangement method thereof, and an image recognition method thereof are provided. In the method, images captured by multiple image capturing apparatuses are obtained. Whether a warning object exists in the images of the image capturing apparatuses is recognized respectively through multiple recognition operations, and each of the recognition operations occupies a part of a system loading of the computer system. If the warning object is recognized in one of the images, the system loading used by the recognition operations is modified, and a person associated with the warning object in the images is determined. The invention dynamically modifies the loading of the computer system and provides a more practical recognition method to enable the computer system to process the recognition operations in real time.
