Abstract
Official abstract text for this publication.
An imaging device capable of image processing is provided. The imaging device can retain analog data (image data) obtained by an image-capturing operation in a pixel and perform a product-sum operation of the analog data and a predetermined weight coefficient in the pixel to convert the data into binary data. When the binary data is taken in a neural network or the like, processing such as image recognition can be performed. Since enormous volumes of image data can be retained in pixels in the state of analog data, processing can be performed efficiently.
First claim
Opening claim text (preview).
The invention claimed is: 1. An imaging device comprising: a pixel block comprising a pixel and a second circuit; and a first circuit, wherein the pixel is configured to obtain a first signal by photoelectric conversion, wherein the second circuit is configured to generate a second signal on the basis of a sum of the first signals, and wherein the first circuit is configured to generate a third signal by binarizing the second signal. 2. The imaging device according to claim 1 , wherein the pixel comprises a photoelectric conversion element, a first transistor, a second transistor, and wherein the first transistor comprises a metal oxide in a channel formation region. 3. The imaging device according to claim 2 , wherein the second transistor comprises silicon in a channel formation region. 4. The imaging device according to claim 2 , wherein the metal oxide comprises indium, gallium, and zinc.
