Title: Ryo Uehara: Digital Camera Inventor

Introduction

Ryo Uehara is an inventor based in Yokohama, Japan. His work includes digital camera technologies, and he is associated with Nikon Corporation. He is credited with 7 patents.

Latest Patents

Uehara’s listed patents address camera operation, power management, and communication with optical equipment.

“Digital Still Camera” describes a reproduction mode designed to reduce power consumption. When the camera enters standby for playback, it displays an indication and waits for user input. If the command dial is not operated within 16 seconds, the camera stops supplying power to various components. When the dial is operated, the camera displays images on an external monitor and indicates that playback is underway. The patent also describes advancing through frames in response to dial operation and returning to standby after three minutes without further input. Operating the sensitivity switch and command dial together allows users to select a frame based on the dial’s direction and rotation.

“Digital Camera and Recording Medium” concerns a camera that can shoot using either a shooting lens or other optical equipment. A mode switch selects the shooting configuration, while an information interface receives information from the selected equipment. When the camera is set to use other equipment, it can receive information about the light source’s color temperature or brightness and use that information to control the camera’s shooting state.
