Abstract
An information input device includes an input panel and one or more circuits. The one or more circuits are configured to determine first, second and third representations of possible proximity of an object to an input panel from first, second and third input frames, respectively. The second input frame is generated after the first input frame, and the third input frame is generated after the second input frame. The one or more circuits are configured to determine whether proximity of the object to the input panel is detected for the second input frame, based on the third representation, if the first and second representations are not similar.
Claims35
An apparatus for detecting proximity of an object, the apparatus comprising:
- an input panel comprising at least one detection element;
- and
- at least one circuit configured to:
- determine, from a first input frame in which input is received via the at least one detection element, a first representation of possible proximity of the object to the input panel;
- determine, from a second input frame in which input is received via the at least one detection element, the second input frame being generated after the first input frame, a second representation of possible proximity of the object to the input panel;
- determine, from a third input frame in which input is received via the at least one detection element, the third input frame being generated after the second input frame, a third representation of possible proximity of the object to the input panel;
- and
- determine whether proximity of the object to the input panel is detected for the second input frame, at least in part by:
- if the first representation indicates a detection of possible proximity of the object to the input panel for the first input frame, the third representation indicates a detection of possible proximity of the object to the input panel for the third input frame similar to the detection for the first input frame, and the second representation does not indicate a detection of possible proximity of the object to the input panel for the second frame similar to the detection for the first input frame,
- determining that generation of noise or loss of information between input frames caused the second representation to not indicate a detection of possible proximity of the object to the input panel, and
- determining that proximity of the object to the input panel is detected for the second input frame;
- wherein the at least one circuit is further configured to suspend determination of whether proximity of the object to the input panel is detected for the second input frame, when the second representation does not indicate a detection of possible proximity of the object to the input panel for the second frame similar to the detection for the first input frame, until the third representation is compared to the first and/or second representation.
