Abstract
The present invention is directed to an information processing apparatus, the method comprising: detecting whether a sheet is set in a measurement device in accordance with a detection condition; in a case where a sheet is detected as being set, measuring a patch formed on the sheet, using the measurement device; and setting a first detection condition for detecting that a sheet is set in the measurement device and a second detection condition for detecting that a sheet is not set in the measurement device to mutually-different conditions.
Claims12
An information processing apparatus comprising:
- a memory that stores instructions;
- and
- a processor that executes the stored instructions to function as:
- a detection unit that detects that a sheet to be fed is placed in a measurement device or a fed sheet is discharged from the measurement device;
- a measurement unit that, in a case where a sheet is detected as being placed, measures a chromaticity value of a patch formed on the sheet, using the measurement device;
- and
- a control unit that sets, to the measurement device, a first detection condition for detecting, in a first cycle, that a sheet to be fed is placed in the measurement device and a second detection condition for detecting, in a second cycle, that a fed sheet is discharged from the measurement device to mutually different detection intervals,
- wherein the first cycle is longer than the second cycle, and
- wherein in a case where the first condition set by the control unit is satisfied, the detection unit determines that the sheet to be fed is placed in the measurement device, and in a case where the second condition set by the control unit is satisfied, the detection unit determines that the fed sheet is discharged from the measurement device.
A control method for an information processing apparatus, the method comprising:
- detecting that a sheet to be fed is placed in a measurement device or a fed sheet is discharged from the measurement device;
- in a case where a sheet is detected as being placed, measuring a chromaticity value of a patch formed on the sheet, using the measurement device;
- and
- setting, to the measurement device, a first detection condition for detecting, in a first cycle, that a sheet to be fed is placed in the measurement device and a second detection condition for detecting, in a second cycle, that a fed sheet is discharged from the measurement device to mutually different detection intervals,
- wherein the first cycle is longer than the second cycle, and
- wherein in a case where the first condition set by the control unit is satisfied, the detection unit determines that the sheet to be fed is placed in the measurement device, and in a case where the second condition set by the control unit is satisfied, the detection unit determines that the fed sheet is discharged from the measurement device.
A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute each step of a control method for an information processing apparatus, the method comprising:
- detecting that a sheet to be fed is placed in a measurement device or a fed sheet is discharged from the measurement device;
- in a case where a sheet is detected as being placed, measuring a chromaticity value of a patch formed on the sheet, using the measurement device;
- and
- setting, to the measurement device, a first detection condition for detecting, in a first cycle, that a sheet to be fed is placed in the measurement device and a second detection condition for detecting, in a second cycle, that a fed sheet is discharged from the measurement device to mutually different detection intervals,
- wherein the first cycle is longer than the second cycle, and
- wherein in a case where the first condition set by the control unit is satisfied, the detection unit determines that the sheet to be fed is placed in the measurement device, and in a case where the second condition set by the control unit is satisfied, the detection unit determines that the fed sheet is discharged from the measurement device.
