Abstract
There is a case where a reading unit cannot read an entire area of a recording medium in a scanning direction of a carriage, or a case where reading accuracy is low in the entire area. In such a case, a result of reading a test pattern for adjusting an ejection timing at each position cannot be obtained with high accuracy in a single reading operation. In order to solve the issue, a recording apparatus performs a reading operation a plurality of times and generates, based on results from the respective operations, an adjustment value for adjusting the ejection timing at each position in the scanning direction.
