Abstract: An image processing apparatus divides an input image into a plurality of band area images, stores the respective band area images in a band memory, and performs image processing. The apparatus comprises: a storage unit configured to store filter coefficients having a two-dimensional reference area of M pixels in a first direction and N pixels in a second direction orthogonal to the first direction; and a spatial filter unit configured to apply, to the band area image stored in the band memory, a spatial filter using the filter coefficients. The filter coefficients are set as the filter coefficients so as to refer to pixels for every K pixels in the second direction, and the spatial filter unit sequentially applies the spatial filter to the band area image K times in the second direction.

Abstract: A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.

Abstract: When an image is recorded using a multichip recording head including a plurality of chips each having a plurality of nozzle arrays, a change in image density can occur due to a registration error between chips in an overlapping part where two chips are connected. To suppress the change in image density, input image data is distributed to two chips such that there are dots overlapping each other between the two chips in the overlapping part.
