CPC Class H04N

Provided is a semiconductor device that can operate stably. All transistors included in the semiconductor device are transistors each of which contains an oxide semiconductor in a channel formation region. The transistor includes a front gate and a back gate. The threshold voltage of the transistor can be shifted in the positive direction or the negative direction depending on a potential applied to the back gate. To make the transistor in a conducting state, the threshold voltage is shifted in the negative direction to increase the amount of current flowing in the transistor, and to make the transistor in a non-conducting state, the threshold voltage is shifted in the positive direction to decrease the amount of current flowing in the transistor. A circuit of the semiconductor device that utilizes this effect and includes transistors all having the same polarity is formed.

An image sensor includes a substrate having a first pixel region and a second pixel region adjacent to the first pixel region, a device isolation layer between the first pixel region and the second pixel region and isolating the first pixel region and the second pixel region from each other, a first transistor disposed in the first pixel region, a second transistor disposed in the second pixel region, and a wiring structure electrically connecting the first transistor and the second transistor. The device isolation layer has a deep trench isolation (DTI) structure which extends from a top surface toward a bottom surface of the substrate.

A solid-state image pickup device includes at least two stacked first and second photoelectric conversion sections in each of a plurality of pixels. Sensitivity of the first photoelectric conversion section to a light incident angle is equivalent to sensitivity of the second photoelectric conversion section to a light incident angle, for each of the pixels.

The present technology relates to an imaging element, a processing method, and an electronic device which are capable of reducing deterioration in an image quality of a captured image caused by power fluctuation. A counting unit includes a counting operation unit that performs a counting operation of counting the count value and a dummy operation unit that performs a dummy counting operation at a timing complementary to the counting operation of the counting operation unit. The present technology can be applied to, for example, an imaging element that counts a count value and performs AD conversion.

Systems and methods for filtering unsafe content by a network security device are provided. According to one embodiment, a network security device captures network traffic and extracts a media file from the network traffic. The network security device then determines the presence of a hidden data item embedded in the media file in a machine-readable form. When such a hidden data item is identified, the network security device performs one or more actions on the media file based on a predefined security policy.
