摘要： A telephone with a video function is provided, including a projection module, a network module, a video-audio capturing module, a conference module and a processor. The network module provides a network interface. The video-audio capturing module is configured to capture an image and voice of a local user, and accordingly generates local video-audio data. The conference module provides the video conference function. The processor is electrically connected to the projection module, the network module, the video-audio capturing module and the conference module. When the processor enables the video conference function of the conference module, the telephone establishes a connection with a remote apparatus through the network interface, in order to receive a remote video-audio data of a remote user from the remote apparatus, and transmit the local video-audio data to the remote apparatus. The projection module projects an image corresponding to the remote video-audio data onto a projection surface.

摘要： A projector and a brightness adjusting method are provided. The projector includes a distance sensor configured to detect a distance between the projector and a projection plane, a light source configured to provide an illumination beam, a brightness controlling circuit configured to control the light source, and a processor coupled to the distance sensor, the light source, and the brightness controlling circuit. The processor calculates according to the distance to obtain an image size of a projected image on the projection plane. The processor obtains a current value corresponding to the image size according to a color table. The processor instructs the light source to adjust a luminous flux of the illumination beam according to the current value for generating a target brightness value of the projected image. When a brightness of the projected image is excessively large, a brightness of an image beam of the projector is automatically reduced.

摘要： A projection apparatus includes a light valve, a lens module, a distance measuring module, a lens position detection module and a processor. The light valve forms an image beam. The lens module projects the image beam onto a display surface. The distance measuring module detects a distance between the lens module and the display surface to obtain a first distance value. The lens position detection module detects a position of the lens module to obtain a second distance value. The processor receives the first distance value from the distance measuring module, receives the second distance value from the lens position detection module and obtains an effective focus range according to the second distance value.
