Abstract: It is determined whether a repeating pattern is present in an image (100). When no repeating pattern is present, the image is divided into patch images, the resultant patch images are used to create a random repeating pattern, and the random repeating pattern is output (108). In addition, when the number of repetitions of the repeating pattern in the image is 2×2 or more (102), the repetition period is determined by transforming pixel values into frequency coefficients, and the repeating pattern is extracted based on the result of determining the repetition period, and is output (104). When the number of repetitions of the repeating pattern in the image is less than 2×2, the repetition period is determined by performing division using local maximum values of autocorrelation coefficients, and the repetition pattern is extracted based on the result of determining the repetition period (106).

Abstract: Predetermined travel locuss are set in a three-dimensional virtual space. Menu panels displaying menu items are arranged along the travel locuss assuming a display position set as a local origin so that the normal to each LCD panel will face a virtual camera. The transparency of a menu panel is raised in accordance with its distance to the virtual camera. A scroll operation moves menu panels along the travel locuss connecting display positions P until a selected specific menu panel reaches the display position P0. A display screen is drawn with the virtual camera and menu panels are three-dimensionally displayed in rolls. By sliding a stylus pen on the LCD panel, the menu screen displayed on the LCD panel scrolls at a velocity corresponding to the drag velocity. When the stylus pen is released from the LCD panel, an application program corresponding to the menu display entity (crosshatched) is activated.

A target value for a steering wheel torque corresponding to the detected steering wheel angle and the acquired yaw angular velocity is set, based on a relationship between yaw angular velocity and resistance-feel level predetermined such that the resistance feel level for a driver monotonically increases with increasing yaw angular velocity. Control is then preformed so as to realize the steering wheel torque target value.
