Abstract
An input device includes a sensor that detects a degree of proximity of an object in each of one or more detection regions on an operation surface, generates one or more sets of detection data corresponding to the detection result for each of the detection regions, and thereby generates N sets of the detection data in total; and an element data generator that generates, based on the N sets of the detection data, M (M is a natural number greater than N) sets of element data indicating degrees of proximity of the object in M sections that virtually divide the operation surface. The element data generator is configured to repeat a data generation process at least two times.
Claims13
An input device that inputs information corresponding to proximity of an object to an operation surface, the input device comprising:
- a sensor that detects a degree of proximity of the object in each of one or more detection regions on the operation surface, generates one or more sets of detection data corresponding to the detection result for each of the detection regions, and thereby generates N sets of the detection data in total;
- and
- an element data generator that generates, based on the N sets of the detection data, M (M is a natural number greater than N) sets of element data indicating degrees of proximity of the object in M sections that virtually divide the operation surface, wherein
- each of the M sections includes overlapping portions overlapping one or more of the detection regions;
- each of the M sets of the element data is a sum of sets of subelement data distributed to the N sets of the detection data according to predetermined percentages;
- each of the N sets of the detection data approximates to a sum of sets of the subelement data distributed from the M sets of the element data according to the predetermined percentages;
- and
- the element data generator is configured to
- repeat a data generation process at least two times, the data generation process including calculating each of tentative values of the N sets of the detection data by totaling the sets of the subelement data distributed from tentative values of the M sets of the element data according to the predetermined percentages, and correcting the tentative values of the M sets of the element data based on N predetermined percentages set for each of the M sets of the element data such that the calculated tentative values of the N sets of the detection data become closer to the N sets of the detection data, and
- calculate, for each of the M sections, a value that is approximate to a convergence value of the element data obtained by the repetition of the data generation process, by obtaining a difference between a first tentative value of the element data obtained in a first execution of the data generation process and a second tentative value of the element data obtained in a second execution of the data generation process, multiplying the difference by a predetermined proportionality coefficient, and adding the multiplied difference to the first tentative value.
