Latest Patents

One of Kenji Itoh's latest patents involves a video camera with a function to correct defective pixels of solid-state image pickup devices. This invention addresses the issue of white spot noise by detecting it through a series of signal processes. The method includes closing the iris and comparing the signal level with the level of only a dark current. Additionally, the gain of an Automatic Gain Control (AGC) circuit is raised to ensure precise detection. This operation is executed during the turn-on or turn-off of the power source, minimizing user annoyance. The reference level for white spot noise detection is optimized based on the temperature of the solid-state image pickup device and its surroundings, ensuring that the detection is not influenced by temperature variations or the AGC circuit's operating state.
