Claims

Based on the reference image data that is image recording information from the host device, recording processing is performed on both the first surface, which is one side of the sheet-like recording medium, and the second surface, which is the back surface of the first surface. In the image recording apparatus to perform,
After the recording process is performed on the first surface of the recording medium, as the acquisition of the first inspection image data, the recording medium before the recording process is performed on the second surface of the recording medium. A first inspection image acquisition unit that images the second surface;
After the recording process is performed on both the first surface and the second surface of the recording medium, as a second inspection image data acquisition, a second inspection that images the second surface of the recording medium An image acquisition unit;
A recording defect inspection unit that inspects a recording defect in a recording process on the second surface of the recording medium based on the reference image data, the first inspection image data, and the second inspection image data; An image recording apparatus comprising: at least.

From the position when the first inspection image acquisition unit acquires the first inspection image data to the position when the second inspection image acquisition unit acquires the second inspection image data. The image recording apparatus according to claim 1, further comprising a medium support member that continuously supports the recording medium during conveyance.

The recording defect inspection unit compares the second inspection image data with an estimation result of the second inspection image data obtained by estimation based on the first inspection image data and the reference image data. The image recording apparatus according to claim 1, wherein the recording defect is inspected by:

The recording defect inspection unit includes a pixel between each pixel constituting the first inspection image and each pixel constituting the reference image on which the recording process is performed on the second surface. The second inspection image is estimated by selecting, for each pixel, one having a lower luminance value from a pair of pixels whose positions on the second surface correspond to each other, and arranging the selected pixels.
