Title: Junpei Endo: Innovator in Image Processing Technology
Introduction
Junpei Endo is a notable inventor based in Hirakata, Japan. He has made significant contributions to the field of image processing, holding a total of 2 patents. His work focuses on enhancing the accuracy and efficiency of image detection technologies.
Latest Patents
One of Junpei Endo's latest patents is an image processor and face detector. This innovative device is designed to detect objects, such as human faces, from images taken against bright sunlight with high accuracy. The image processor adjusts the image signal from an image pickup unit at an analog gain through an image adjuster. The processed signal is then converted into a digital format and stored in memory. A feature extraction process identifies the object area in the digital image data. If the object area is not detected, the analog-gain controller adjusts the image signal at different analog gains, repeating the detection process until successful.
Another significant patent is the scan converter. This device includes first and second memories, along with a frame memory that operates with distinct write and read periods. The video data input circuit writes data into the memory at a first transfer rate, while the video data output circuit retrieves data at a third transfer rate. The transfer rate between the memories is optimized to be twice as fast as either the first or third transfer rate, ensuring efficient data handling.
