Abstract

Disclosed are an information input device, an information input method, an information input / output device, and an electronic device. The information input device includes an input panel including detection elements each obtaining a detection signal from an object; an image processing section performing predetermined image processing on the detection signal obtained by the input panel, thereby obtaining touch point information which is indicative of whether the object is in a touch state and proximity point information which is indicative of whether the object is in a proximity state. The information input device further includes a drive section driving each of the detection elements in the input panel in such a manner that the detection signal is obtained from each of the detection elements at predetermined drive intervals; and a control section determining the drive interval based on the touch point information and the proximity point information obtained by the image processing section.

Description

technical field [0001] The present invention relates to an information input device, an information input method, an information input program, an information input / output device, and an electronic device that input information through contact or proximity of an object. Background technique [0002] In recent years, displays are being developed that have contact sensors that allow input of information by direct contact of a finger or the like with the display screen of the display. Types of touch sensors include an optical type that optically detects a finger or the like, a contact type that detects a position of a touched electrode, and a capacitive type that uses a change in capacitance. For example, in an optical type touch sensor, an object approaching a display screen is irradiated with image display light or the like, and the presence or absence of the object or the position of the object, etc. is detected based on light reflected from the object, for example, as in Ja...
