摘要： In reading an original by mounting reading means (scanner unit) on a recording apparatus, the advancing width of the original is so reduced that the reading bands k, k+l, . . . , are partially overlapped. For example in the color image reading, in generating the data of the (k+1)-th band, the data of a range overlapped with the k-th band are corrected by the data of the k-th band (for example by simple averaging), thereby achieving image reading without bandwise density fluctuation regardless of the reading mode and the original size.

摘要： Disclosed is an image reading apparatus in which the band width for reading by one scanning is variable in accordance with the original size, the reading mode, etc. R, G, and B image data of the k-th band is successively read in one-band width to store image data R1, G1, and B1 of pixel coordinates X(n, m). Then, the original is fed so as to cause partial overlapping of the (k+1)-th band with a lower predetermined pixel region of the k-th band, and R, G, and B image data of the (k+1)-th band is read in one-band width to successively store image data R2, G2, and B2 of pixel coordinates X(n, m′). The image data obtained through overlap reading of the k-th band and the (k+1)-th band is averaged to calculate correction image data, which is transferred to a host computer along with along other image data which has not been averaged as read image data. And, it is possible to optimize reading time according to the kind of original, reading mode, etc., without involving a deterioration in image quality.

摘要： In an image processing apparatus, after a current band of an image has been read, an original is fed at a distance of the upper half band width of the current band. When the next band is read, the current band at the lower half band width is overlappingly read. The band data at the lower half band width of the current band is stored in a memory, and the next band is read. Averaging processing or function processing is applied to the band data which has been overlappingly read.

A scanner head cartridge is held on a carriage that moves an ink head cartridge of an ink-jet printer for performing recording on a recording medium, in place of the ink head cartridge, and can be commonly used using a common base unit even in carriages which mount different ink head cartridges and have different shapes. In addition, the scanner head cartridge allows easy adjustment of the optical system.

摘要： In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

摘要： When dividing multi-valued data and generating data for two-pass multi-pass printing, in addition to divided multi-valued data that are divided for each of the two passes, divided multi-valued data that is common to both of the two passes is generated. Moreover, quantized data of that common multi-valued data is reflected onto the quantized data for each pass. Furthermore, when generating quantized data, division ratios that are used when generating the common data by the multi-valued data division described above are set according to the image characteristics (whether or not the area is flesh color) of the multi-valued data. Thereby, it is possible to perform high-quality printing regardless of the image characteristics by taking a suitable balance between suppressing density unevenness and suppressing graininess.
