Abstract:
A jitter control apparatus, comprising:a first optical prism installed to be rectilinearly transferable in a right-angled direction with respect to an optical axis for refracting and transmitting incident light so that the angle of emission is smaller than the angle of incidence with respect to the transfer direction;a first actuator for rectilinearly transferring said first optical prism;a second optical prism installed to be adjacent to said first optical prism and rectilinearly transferred in a right-angled direction with respect to the direction in which said first optical prism is transferred for refracting and transmitting the incident light so that the angle of emission is smaller than the angle of incidence with respect to the direction in which said second optical prism is transferred; anda second actuator for rectilinearly transferring said second optical prism,wherein an image formed on the photographing screen is prevented from vibrating by appropriately transferring said first and second optical prisms according to the degree of jitter of an incident image.
