Design and implementation of a scanner with stitching of multiple image capture

Ying-Wen Bai;Chien-Chung Cheng

IEEE Transactions on Consumer Electronics
Year: 2008 | Volume: 54, Issue: 4 | Journal Article |
Cited by: Papers (2) | Patents (3)
Instead of the flatbed scanner which moves slowly as it scans, we propose in this paper a new design of a high-speed and low-power scanner with a stitching of multiple image capture. We divide the area to be scanned into four parts, capture each image and then stitch these into a whole. Our design uses the compact camera module (CCM) advantages of high integrity, white balance, advanced cali...Show More

A 216 × 216 Global-Shutter CMOS Image Sensor With Embedded Analog Memory and Automatic Exposure Control for Under-Display Optical Fingerprint Sensing Applications

Ping-Hung Yin;Chih-Wen Lu;Jia-Shyang Wang;Yuan-Chang Chien;Cheng-Te Chou;Guo-Dung John Su;Poki Chen

IEEE Transactions on Circuits and Systems I: Regular Papers
Year: 2023 | Volume: 70, Issue: 3 | Journal Article |
A $216\times216$ under-display optical fingerprint CMOS image sensor (CIS) is proposed and was prototyped using 0.11- $\mu \text{m}$ CIS technology. Two analog storage nodes that act as a ping-pong buffer are embedded in each pixel of the global-shutter CIS, rendering a digital buffer unnecessary and increasing the operating frame rate. A processor with automatic exposure (AE) and black-level c...Show More
