Title:
IMAGE FORMING METHOD AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2001298657
Kind Code:
A
Abstract:

To photograph the objects at different distances and to form a clear image of every object.

The images focused on the objects P, T and M set at the short, medium and long distances are formed by the CCD 8, 9 and 10 respectively and stored in a memory. Each of these focused and photographed images of different distances is fractionated into plural blocks and a difference waveform, i.e., the difference between the luminance value and its movement mean value is formed in each block to the image of every distance. On the basis of difference waveforms, the clearest one of image blocks of every distance is decided and the clearest image blocks of every distance are connected together into the image of each object. In such a constitution, the accurate definition can be decided even with a small object that is not main and has no conspicuous outline or even when the miscellaneous beams are included in the blocks.
