An output unit transmits the output data thus converted to a main processor via an interface. A switching unit receives, from the main processor via the interface, a mode switching signal for switching detection sensitivity. The conversion unit switches the conversion table for reference based on the mode switching signal. The conversion table is a bit conversion table for reducing the number of bits of the output data. ## Claims ### Claim 1 An input device control apparatus, comprising: a conversion unit configured to convert output data detected by an input device based on a conversion curve selected from among a plurality of different conversion curves, where the input device is a pressure-sensitive input device configured to produce the output data that varies as a function of pressures of touch inputs, and each of the plurality of different conversion curves has variable ordinate values as a function of pressure; an output unit configured to transmit the converted output data to a main processor via an interface; and a switching unit configured to receive, from the main processor via the interface, a mode switching signal for switching detection sensitivity, wherein the conversion unit switches the selected conversion curve for reference based on the mode switching signal, and wherein the plurality of different conversion curves include at least one pressure correction curve that is highly sensitive to low pressure, at least one pressure correction curve that is highly sensitive to high pressure, and at least one pressure correction curve that is highly sensitive to a specific pressure range. ### Claim 2 (depends on 1) The input device control apparatus according to claim 1, further comprising a bit conversion table for reducing a number of bits of the output data. ### Claim 3 (depends on 1) The input device control apparatus according to claim 1, wherein the plurality of conversion curves have different detection sensitivities. ### Claim 4 (depends on 1) The input device control apparatus according to claim 1, wherein the switching unit switches, according to the type of an application or a situation of use in a single application, the pressure correction curve that is highly sensitive to low pressure, the pressure correction curve that is highly sensitive to high pressure, and the pressure correction curve that is highly sensitive to a specific pressure range. ### Claim 5 An input device control method comprising: converting output data detected by an input device based on a conversion curve selected from among a plurality of different conversion curves, where the input device is a pressure-sensitive input device configured to produce the output data that varies as a function of pressures of touch inputs, and each of the plurality of different conversion curves has variable ordinate values as a function of pressure; transmitting the converted output data to a main processor via an interface, thereby outputting the output data; and receiving, from the main processor via the interface, a mode switching signal for switching detection sensitivity, wherein the converting includes switching the selected conversion curve for reference based on the mode switching signal, and wherein the plurality of different conversion curves include at least one pressure correction curve that is highly sensitive to low pressure, at least one pressure correction curve that is highly sensitive to high pressure, and at least one pressure correction curve that is highly sensitive to a specific pressure range. ### Claim 6 A non-transitory computer-readable recording medium containing a computer program, which when executed by a computer causes the computer to carry out actions, comprising: converting output data detected by an input device based on a conversion curve selected from among a plurality of different conversion curves, where the input device is a pressure-sensitive input device configured to produce the output data that varies as a function of pressures of touch inputs, and each of the plurality of different conversion curves has variable ordinate values as a function of pressure; transmitting the converted output data to a main processor via an interface, thereby outputting the output data; and receiving, from the main processor via the interface, a mode switching signal for switching detection sensitivity, wherein the converting includes switching the selected conversion curve for reference based on the mode switching signal, and wherein the plurality of different conversion curves include at least one pressure correction curve that is highly sensitive to low pressure, at least one pressure correction curve that is highly sensitive to high pressure, and at least one pressure correction curve that is highly sensitive to a specific pressure range.
