摘要： An image capturing device including an image sensing circuit and a processing circuit is provided. The processing circuit controls the image sensing circuit to sense at least one partial frame before sensing a full frame. A number of pixels of the partial frame is less than a number of pixels of the full frame, and exposure time of the partial frame is shorter than exposure time of the full frame. The processing circuit performs an automatic exposure procedure according to the partial frame to calculate a fast exposure time and gain, transforms the fast exposure time and gain into exposure time and gain for the full fame, and control the image sensing circuit to sense the full frame accordingly.

摘要： A pixel circuit is disclosed. The pixel circuit includes a photodiode (PD), a transmission circuit, a reset circuit, a signal storage circuit and a buffer circuit. The transmission circuit is coupled between the PD and an ordinary floating diffusion (FD) node. The reset circuit is coupled to the ordinary FD node. The signal storage circuit is coupled to the ordinary FD node. The buffer circuit is coupled to the ordinary FD node. The signal storage circuit may store a PD signal on a specific node having a reduced leakage path in comparison with the ordinary FD node during a holding phase of the pixel circuit, wherein the holding phase is a time interval starting from a first time point at which the PD signal is stored on the specific node and ending at a second time point at which the pixel circuit is selected for performing a read-out operation.

摘要： The invention is directed to a method of operating an image sensor. A first integration is performed on a first photodiode of a pixel circuit to obtain at least one first image signal. A second integration is performed on a second photodiode of the pixel circuit to obtain a second image signal, the first photodiode having a photodiode area larger than the second photodiode. A third integration is performed by collecting blooming charge overflowing from the first photodiode to obtain an overflow image signal. The first integration has longest integration time and the third integration has shortest integration time among the first integration, the second integration and the third integration.
