    摘要： An imaging device with an arithmetic function in which the circuit size is reduced is provided. The imaging device includes a plurality of pixel blocks. Each of the pixel blocks includes N (N is an integer greater than or equal to 1) first circuits, N second circuits, and a third circuit. Each of the first circuits includes a photoelectric conversion device, and the photoelectric conversion device has a function of converting incident light into an electrical signal and has a function of outputting a first signal that is obtained by binarizing the electrical signal to the second circuit. Each of the second circuits has a function of outputting a second signal that is obtained by multiplying the first signal by a weight coefficient to a third circuit. When the N second signals are output to a wiring electrically connected to the third circuit, addition is performed. The first circuit includes a transistor, and an OS transistor is preferably used as the transistor.

    摘要： A semiconductor device storing data as a multilevel potential is provided. The semiconductor device includes a memory cell, first and second reference cells, first and second sense amplifiers, and first to third circuits. The first circuit has a function of outputting, to a first wiring and a third wiring, a first potential corresponding to a first signal output from the memory cell. The second circuit has a function of outputting, to a second wiring, a first reference potential corresponding to a second signal output from the first reference cell. The third circuit has a function of outputting, to the fourth wiring, a second reference potential corresponding to a third signal output from the second reference cell when a second switch is in an off state. The first sense amplifier refers to the first potential and the first reference potential and changes potentials of the first wiring and the second wiring. The second sense amplifier refers to the first potential and the second reference potential and changes potentials of the third wiring and the fourth wiring.

    摘要： An image processing method for increasing the stereoscopic effect of an image is provided. Difference mask data including an object area and a background area is created from image data, and the center coordinate of the object area is calculated. Then, a gradation pattern is selected in accordance with the average brightness value of the object area and applied to the background area, whereby a gradation mask data is created. After that, the image data of the background area is converted into image data based on the gradation mask data, so that the stereoscopic effect of the image is increased.
