<p><P>PROBLEM TO BE SOLVED: To provide a display-and-image-pickup device capable of detecting an object stably, regardless of use situations. <P>SOLUTION: In accordance with size of a prescribed parameter, switching processing of two finger tip extraction processing is performed. When the parameter is in an increase process and the parameter reaches a first threshold, one of the two finger tip extraction processing is switched to the other finger tip extraction processing. Meanwhile, when the parameter is in a decrease process and the parameter becomes a second threshold value smaller than the first threshold, the switched finger tip extraction processing is switched to the other fingertip extraction processing. Thus, even when the parameter fluctuates around the first threshold or the second threshold, for example, a change of acquisition mode with high frequency is avoided. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
