Patent ID: 8259157

Claim:
A teleconference terminal apparatus comprising: imaging field changing control means for carrying out control for changing the position of an imaging field changing unit designed to change the position of the imaging field of view of an imaging unit that forms a teleconference system; preset information managing means for holding and managing preset information including positional information that specifies the position of the imaging field changing unit; image signal transmitting means for outputting and transmitting an image signal to another teleconference terminal apparatus, the image signal used to display an image on a display apparatus provided in the other teleconference terminal apparatus; still image generating means for generating still image information based on a picked-up image signal obtained through imaging performed by the imaging unit; and transmitted image control means for controlling the image signal transmitting means to transmit an image signal based on a picked-up image signal obtained through imaging performed by the imaging unit during a first period in which the imaging field changing control means does not carry out position changing control for changing the position of the field view changing unit based on the positional information in the preset information, and controlling the image signal transmitting means to transmit, during a second period in which the position changing control is carried out, an image signal based on still image information generated by the still image generating means when the second period is initiated.
