Display control device, display control method and portable apparatus

Abstract

A display control device and a display control method capable of detecting the position and direction of an apparatus by a simple structure and controlling a display of a displayed image based on the detected position and direction of the apparatus. Two cameras (21, 22) are mounted on an apparatus (20). A user (10) holds the apparatus (20) in the hand and takes by a first camera (21) a first image including the user's own face and takes by a second camera (22) a second image including a scene opposite the user. A display control section (30) extracts features of the face from the first image and extracts scene feature points from the second image. Then the display control section (30) compares the extracted results with standard figures etc. to calculate the distance ro to the apparatus (20) and the directions thetao, Phio of the apparatus (20), and controls the display of the displayed image based on the calculated distance ro and directions thetao, Phio.

Description

technical field [0001] The present invention relates to a display control method using image measurement and image recognition, and more particularly, to a method for detecting the position or orientation of a device on which a camera is installed using a photographed image of a camera, and controlling the display based on the detected position or orientation of the device. Shows the techniques used to control. Background technique [0002] In recent years, due to the popularization of the Internet, computers and home appliances are connected to each other, and remote operations or media convergence are formed, that is, a ubiquitous network society. Its feature is that the degree of freedom of communication is improved anytime and anywhere, and the user can act regardless of the difference between the devices and the physical distance between the devices. In order to realize the ubiquitous network society, first of all, network connection on the system side is a necessary c...

Problems solved by technology

However, for example, accelerometers cannot cope with constant speed motion, so there is a problem in sensor sensitivity

In this regard, although it is effective to use a so-called sensor that detects and supplements position and orientation information from multiple angles such as a magnetic sensor or an ultrasonic sensor, adding a sensor increases the cost of the system. It also increases the size and weight of the device

In addition, since there are many cases where the sensors are constantly operating, the increase in the number of sensors will cause an increase in the power consumed by the device, which is especially problematic for portable devices.
