Abstract
An image processing apparatus includes an image sensor, a reference member, and a data processing portion. The reference member includes a white reference surface that opposes the image sensor via a conveying path. The data processing portion detects a reference dark image that falls below a reference light amount from reference image data expressing a detection light amount of the image sensor obtained when a sheet is not being conveyed. The data processing portion further detects a target dark image that falls below the reference light amount from data whose position in the main direction differs from a position of the reference dark image out of target image data expressing a detection light amount of the image sensor obtained when the sheet is being conveyed. Thus, the data processing portion detects a base end position corresponding to a tip end portion of the sheet in the target image data.
