摘要： An image reading apparatus includes a light emitting element, a luminance calculating unit, a light amount setting unit, and a storing unit. The light amount setting unit, in each line period, causes the light emitting element to emit a light with gradually changing a reference light amount from a reference light amount set as a default value from among a plurality of reference light amounts stored in the storing unit, identifies a reference light amount so that the luminance calculated by the luminance calculating unit is within a predetermined range, sets the identified reference light amount as a default value for the next line period, and causes the storing unit to store that reference light amount.

摘要： A read image processing apparatus is provided for processing a read image read by line image sensors arranged such that one end parts of which adjacent to each other are overlapped in a sub-scanning direction. The read image processing apparatus includes a density variation detector, a seam processor, and a line image generator. The density variation detector detects whether a density variation occurs for not less than a predetermined number of times or not in each of a plurality of regions in a seam-read image. The seam processor generates a seam image by synthesizing the seam-read images read by the line image sensors adjacent to each other in accordance with a detection result made by the density variation detector. The line image generator generates a read image corresponding to one line based on read images read by the line image sensors and the seam image generated by the seam processor.
