A direction detector section detects an eye direction or face direction of a conference attendant from image data picked up by a camera, and supplies information to an attention level detector section. Based on the information supplied from the direction detector section, the attention level detector section operates information (parameter) of a attention level to adjust sound data and/or image data of the other conference attendants inputted from the other remote conference apparatuses. An adjusting section adjusts corresponding sound data and/or image data by using information of the attention level supplied from the attention level detector section, and the data are outputted as sound from loudspeakers and displayed on monitor sections. In this manner, speech of each of the conference attendants can be heard easily and an image of each conference attendant can be watched easily.
