Publication number: 20120130510Abstract: Control devices, methods, and programs set a final control value by smoothly shifting from the control value to a final control value. The devices, methods, and programs specify an operation amount of a user operation with respect to a prescribed control value, and access a pre-change control value that is a value of the control value before a completed change. Based on the accessed pre-change control value and the specified operation amount of the user operation, devices, methods, and programs set a final control value by changing the control value in a stepwise manner from the pre-change control value to the final control value within a prescribed control value range.Type: ApplicationFiled: November 9, 2011Publication date: May 24, 2012Applicant: AISIN AW CO., LTD.Inventor: Hidenori NAGASAKA

Publication number: 20120098868Abstract: An image display devices, methods, and programs that displays an image on a display screen. The devices, methods, and programs detect pressed coordinate positions on the display screen, store the detected pressed coordinate positions in a memory at a predetermined time interval in a time sequence, and if, after a pressing on the display screen has been cancelled, the display screen is not pressed again before a predetermined pressing cancellation judging time passes, determining a cancellation of the pressing on the display screen. The devices, methods, and programs set a predetermined delay time based on the predetermined pressing cancellation judging time, after the predetermined delay time has passed since the pressing on the display screen started, read out the stored pressed coordinate positions at the predetermined time interval and in the time sequence, and scroll the image so as to follow a movement of the read-out pressed coordinate positions.Type: ApplicationFiled: October 21, 2011Publication date: April 26, 2012Applicant: AISIN AW CO., LTD.Inventor: Hidenori NAGASAKA
