An image recording apparatus is provided which records an image by scanning, relatively to a recording medium, a line-type recording head unit in a direction substantially perpendicular to a predetermined direction, wherein the line-type recording head unit includes a plurality of recording heads which are disposed in a direction substantially the same as the predetermined direction and which have recording width that partially overlap each other and wherein each of the recording heads has a plurality of recording elements disposed in a direction substantially the same as the predetermined direction. The image recording apparatus includes a correction data generator for producing correction data for correcting characteristics of respective recording elements at two-dimensional positions on the recording medium, and an adjustment unit for adjusting an input image signal inputted to the recording elements at the two-dimensional positions, based on the correction data.

A format storage unit stores a predetermined geometric property format. A chart data creating unit creates chart data based upon the geometric property format, and a printing unit creates a test chart by printing mark groups on a recording medium such as a paper sheet based upon the chart data. An image pickup unit outputs a chart image by scanning the test chart, and a mark center calculating unit calculates the center of each mark based upon the chart image. A fitting unit performs a fitting calculation comparing calculation results output from the mark center calculating unit and the chart based upon the geometric property format such that the squared difference therebetween becomes minimum for each mark position.

An image recording device comprises: a first and second recording heads (11, 12) formed of recording elements cyclically arrayed, which are continuously arrayed with an overlapped region; image data distributing means (2) for distributing image data to these recording heads (11, 12); image data distribution region variation means (3) for setting an image data distribution region where the image data of each pixel is distributed to both the recording heads (11, 12) by the image data distributing means 2; correction parameter storage means (5) for storing a correction parameter for correcting the difference in the image density properties between the image data distribution region and the other region due to phase difference between the recording heads (11, 12); and image data correcting means (4) for correcting the image data in the image data distribution region based upon the correction parameter.

Disclosed herein is an image processing apparatus, in which an object image focused by a lens is split into a plurality of images by means of a light splitting section. These images are converted into image data items by a plurality of imaging devices which are arranged with their imaging area overlapping in part. The image data items are stored temporarily in an image storing section. A displacement detecting section detects displacement coefficients (rotation angle R and parallel displacement S) from the image signals representing the mutual overlap region of two images which are to be combined and which are represented by two image data items read from the image storing section. The position of any specified pixel of the image displayed is identified by the pixel signal generated by the corresponding pixel of any imaging device. An interpolation section performs interpolation on the pixel values of the imaging device, thereby correcting the values of the other pixels of the image displayed and ultimately generating interpolated image signals. The interpolated image signals are combined with the image signals produced by the imaging device, whereby a display section displays a high-resolution image.
