摘要： There is an image processing apparatus to perform an image editing process such as to extract a part of an image or to synthesize a plurality of images. This apparatus comprises: an image information generator to generate image information; an area information generator to generate area information to extract a desired area of the image information; a coding circuit to compress and code the area information; a memory to store the area information which was compressed and coded by the coding circuit; a decoder to decode the area information in the memory; and an extracting circuit to extract the desired area of the image information on the basis of the area information which was decoded by the decoder. The coding circuit codes the area information on a unit basis of n.times.m pixels by use of a coding look-up table. The decoder also decodes the area information by use of a decoding look-up table. The image information is separated into lightness information and shape information on a unit basis of n.times.m pixels and stored. Thus, the capacity of the memory can be reduced.

摘要： In a semiconductor laser optical system which uses a light source a semiconductor laser having different diverging points and divergence angles in orthogonal directions and in which the light beam from the light source is imaged on a scanned surface, only a spherical surface optical system is provided between the semiconductor laser and the scanned surface. The spherical surface optical system includes two partial optical systems, i.e. a first image forming optical system and a second image forming optical system as viewed from the light source side. By selecting the optical constant of one of the two image forming optical systems to a predetermined value, the peak power of the image forming spot on the scanned surface is maximized.
