摘要： An apparatus for spatially correcting an image frame is disclosed. In some embodiments, the apparatus stores a frame of pixel values and scans a multi-pixel correction window across the frame. Spatial correction is performed on pixels within the window at correction positions during the scan. The spatial correction comprises estimating pixel values at value estimation positions based on one or more pixel values within the window for pixels satisfying a logical condition. The value estimation positions correspond to pixel values which do not fall within the window again during the scan. Further disclosed is an apparatus for detecting high-energy radiation, in which integration circuitry is used for integrating charge responsive to radiation photon interaction events. The circuits are controllable in accordance with an exposure control signal to vary an exposure window duration according to an operating parameter of the apparatus.
摘要翻译： 公开了一种用于空间校正图像帧的装置。 在一些实施例中，该装置存储一帧像素值，并跨越该帧扫描多像素校正窗口。 在扫描期间的校正位置处对窗口内的像素执行空间校正。 空间校正包括基于满足逻辑条件的像素在窗口内的一个或多个像素值来估计值估计位置处的像素值。 值估计位置对应于在扫描期间不再落入窗口内的像素值。 进一步公开的是一种用于检测高能辐射的装置，其中集成电路用于响应于辐射光子相互作用事件积分电荷。 电路根据曝光控制信号是可控的，以根据装置的操作参数改变曝光窗持续时间。
