Title:
半導体装置
Document Type and Number:
Japanese Patent JP7016931
Kind Code:
B2
Abstract:
To provide a novel semiconductor device, a semiconductor device capable of operating at a high speed, or a semiconductor device with reduced area, or a semiconductor device with low power consumption. The semiconductor device which has a function of taking a moving image includes a pixel portion including a plurality of pixels, a first circuit, and a second circuit. Each of the plurality of pixels has a function of converting irradiation light to generate first data and a function of generating second data corresponding to a difference between the first data in a first frame period and the first data in a second frame period. The first circuit has a function of converting the second data into a digital signal and outputting the digital signal as compressed data of the moving image. The second circuit has a function of controlling output of the compressed data.
