    Abstract: Color filters are used for color images obtained using imaging devices such as conventional image sensors. Imaging elements with color filters are sold, and an appropriate combination of the imaging element and a lens or the like is incorporated in an electronic device. Only providing a color filter to overlap a light-receiving region of an image sensor reduces the amount of light reaching the light-receiving region. An imaging system of the present invention includes a solid-state imaging element without a color filter, a storage device, and a learning device. Since the color filter is not included, colorization is performed on obtained monochrome image data (analog data), and coloring is performed using an AI system.

    Abstract: In a video voltage comparator circuit, an average of first video voltages applied to pixel electrodes of pixels in the second-half rows in a k-th frame period (k is a natural number) is compared with an average of second video voltages applied to pixel electrodes of pixels in the first-half rows in a (k+1)th frame period for each row. In an overdrive voltage switching circuit, when a difference obtained from the comparison in the video voltage comparator circuit is greater than or equal to a threshold value, the overdrive voltage in the (k+1)th frame period is switched to a first overdrive voltage, and when the difference obtained from the comparison in the video voltage comparator circuit is less than the threshold value, the overdrive voltage in the (k+1)th frame period is switched to a second overdrive voltage lower than the first overdrive voltage.

    Abstract: An electronic device that enables smooth communication is provided. The electronic device includes a display portion including a first camera; a second camera; and an image processing portion. The second camera is positioned in a region not overlapping with the display portion. The first camera has a function of generating a first image of a subject, and the second camera has a function of generating a second image of the subject. The image processing portion includes a generator that performs learning using training data. The training data includes an image including a person's face. The image processing portion has a function of making the first image clear when the first image is input to the generator and a function of tracking the gaze of the subject on the basis of the second image.
