Abstract: An imaging device capable of executing image processing is provided. An imaging device with low power consumption is provided. A highly reliable imaging device is provided. An imaging device with higher integration degree of pixels is provided. An imaging device manufactured at low cost is provided. The imaging device includes a photoelectric conversion device, a first transistor that is formed in a first layer and includes silicon in a channel formation layer, and a capacitor that is formed in a second layer bonded to the first layer. One of a source and a drain of the first transistor is electrically connected to one of electrodes of the photoelectric conversion device, and the other of the source and the drain of the first transistor is electrically connected to one of electrodes of the capacitor. A pixel having a function of generating first data and a function of multiplying the first data to have a given magnification to generate second data is included.

Abstract: An imaging system that has an image processing function and is capable of generating an interpolation image is provided. The imaging system has an additional function such as image processing and can generate an interpolation image by using image data output from an imaging device. The imaging device can perform filter processing in parallel during a light exposure period, and thus can perform a large amount of arithmetic operation and generate a high-quality interpolation image. The number of arithmetic operations can be further increased particularly during image capturing in a dark place, which requires a long exposure time. Accordingly, the frame rate can be substantially increased, and high-quality moving image data can be generated.

Abstract: An imaging device capable of executing image processing is provided. Analog data (image data) acquired through an imaging operation is retained in a pixel, and data obtained by multiplying the analog data by a given weight coefficient in the pixel can be extracted. The data is taken into a neural network or the like, whereby processing such as image recognition can be performed. Since an enormous amount of image data can be retained in pixels in an analog data state, processing can be performed efficiently.

Abstract: An imaging device having a motion detecting function and an image processing function is provided. The imaging device can detect a difference between a reference frame image and a comparative frame image, and can switch from a motion detecting mode to a normal image capturing mode when a significant difference is detected. A low-frame-rate operation in the motion detecting mode can reduce power consumption. Moreover, the imaging device has an image recognition function in combination with the motion detecting function, so that switching from the motion detecting mode to the normal image capturing mode can be performed when a particular image is recognized.

Abstract: An oil mist separator that is provided at a portion further up than a cylinder head in an internal combustion engine body, includes: an oil mist separating unit that separates oil mist contained in a blow-by gas that is generated from the internal combustion engine body, wherein the oil mist separating unit includes a first member that is arranged in a lower portion and has a partitioning wall shape, and a second member that is arranged above the first member, and includes a first blow-by gas inlet port which is provided at a position further up than the first member and through which the blow-by gas flows into the oil mist separating unit.

Abstract: A storage system continues its operation to reduce the influence on a wide link by abnormal physical wiring and so as not to lose the redundancy of the system. At least one physical wiring line is selected from among two or more physical wiring lines, the selected physical wiring line is invalidated, the presence of an abnormal transmission line generation is confirmed in the data transfer that uses physical wiring line other than the invalidated physical wiring line, and when the abnormal transmission line is confirmed, the selected physical wiring line is recognized normal wiring line.
