<P>PROBLEM TO BE SOLVED: To solve the following problem of a device for controlling an electronic apparatus by the movement of a hand in a space of a user to a displayed operation button: there are some cases where a flag representing that the user is above the operation button can not be obtained, depending on the way of movement of the user's hand to a plurality of arranged operation buttons. <P>SOLUTION: A first operation detector 91 outputs an activation flag being a pulse which is output while the hand is put near a push button being displayed, and represents that the push button is selected. A flag generator 111 outputs an operation detection flag of a high level, when the value of movement generation amount data output from a time difference filter 53 according to an area where the hand is put in a peripheral detection region around a detection region corresponding to the push button, is not lower than a predetermined threshold. Based on the activation flag and the operation detection flag, a flag controller 112 generates a flag for stopping writing, into a memory, an image signal at the detection region inside the difference filter 53. <P>COPYRIGHT: (C)2009,JPO&INPIT |
