<p>An image compressing circuit (1) and a standby image compressing circuit (5) are connected parallel to each other, and a selector (3) selects either one of output signals from the image compressing circuit (1) and the standby image compressing circuit (5). A first delay circuit (2) is connected in a stage following the image compressing circuit (1), and a second delay circuit (2) is connected in a stage preceding the standby image compressing circuit (5). When the image compressing circuit (1) suffers a fault in its image compressing process, a CPU (6) indicates the fault to the standby image compressing circuit (5) and the selector (3). The standby image compressing circuit (5) then outputs a compressed signal, and the selector (3) selects the compressed signal outputted from the standby image compressing circuit (5). <IMAGE></p> |
