Abstract
A carriage including a sensor scans a printing medium, and a measurement value measured by the sensor is stored in a memory over the scanning range. When a predetermined event occurs, storage control for storing the measurement value in the memory is performed.
Claims6
A measuring apparatus comprising:
- a sensor;
- a scanning unit configured to cause said sensor to scan a measurement target object;
- a memory including a plurality of memory areas configured to be able to store a first number of measurement values measured by said sensor, in each of the plurality of memory areas;
- and
- a storing unit configured to store, every time a predetermined event occurs for the measurement value measured by said sensor, the first number of measurement values that are measured before and after the event in one of the plurality of memory areas,
- wherein said storing unit stores the measurement value measured by said sensor in the one memory area by the time the event occurs, and a second number of measurement values which is smaller than the first number in the one memory area and a next storing target memory area after the event has occurred.

A control method of a memory, comprising:
- a detection step of detecting an occurrence of a predetermined event for a measurement value measured by a sensor when the sensor scans a measurement target object;
- and
- a storing step of storing, every time the occurrence of the predetermined event is detected in the detection step, a first number of measurement values that are measured before and after the event in one of a plurality of memory areas allocated to the memory, and storing a second number of measurement values in a next one of the plurality of memory areas,
- wherein the second number of measurement values are measured after the event among the first number of measurement values.
