SELECTIVE-SCALING TELEVISION CAMERA Russian patent published in 2003 - IPC

FIELD: television engineering. SUBSTANCE: proposed camera is primarily used for observation systems in which one receiving screen displays composite image distinguished from primarily submitted image by that it consists of enlarged section and remaining constant-scale part. Chosen fragment is scaled while maintaining constant resolution within entire composite image while keeping location of enlarged image in first-choice region. Newly introduced in camera are beam splitter, second television signal sensor of positioning unit, sync pulse selector, mixing switch, constant delay unit, adjustable delay unit, and sync pulse shaper; second sensor operates in injection synchronization mode with delay controlled from first sensor.
