Disclosed are an apparatus and method for converting 2D input image signals into 3D stereoscopic image signals and outputting the converted 3D stereoscopic image signals. According to the method of converting image signals according to an embodiment of the present inventive concept, first, motion information about a current frame that is 2D input image signals is acquired, and then a motion type of the current frame is determined using the acquired motion information. As a result of the determination, if the motion type of the current frame is a horizontal motion frame, it is determined whether the current frame is a scene change frame. If the current frame is the horizontal motion frame and is not the scene change frame, 3D output image signals are generated using a current image and a delayed image. If the current frame is not the horizontal motion frame, or if the current frame is the horizontal motion frame and the scene change frame, a depth map is applied to the current image and 3D output image signals are generated. In this case, the depth map is acquired using the horizontal boundary and a difference in a sense of depth according to a vertical location to embody a stereoscopic image.

An image forming apparatus performs a single-side image formation such that, when a delay is needed, a stacked sheet discharge control section controls a sheet carrying mechanism so that: a first sheet (for a second imaging job) to be discharged after passing a first sheet-discharging roller via a first sheet-carrying path is directed to another carrying path without being discharged, and is stood by therein. The first sheet and a second sheet (for the second imaging job) which is carried to the first sheet-discharging roller via the first sheet-carrying path after the first sheet, then are concurrently discharged overlappingly. This eliminates needs for delaying image formation for the second imaging job, and for securing time for post-process for the first imaging job. Even if a delay is inevitable, this reduces the delay time greatly and improves the productivity of the image forming apparatus, without reducing its performance wastefully.

A first adding circuit sums an input image signal of a target pixel and a value that is derived by multiplying respective display errors of three pixels, which are before the target pixel by one line, by weighting factors. A gradation candidate converter converts the gradation of the summed image signal to a plurality of available gradation candidates that are convertible when an error of the immediate left pixel is added. A delaying circuit delays the summed image signal. A second adding circuit sums the delayed image signal and a value that is derived by multiplying the error generated in the immediate left pixel by a weighting factor. A gradation selector selects a gradation closest to the gradation of the image signal to which the error is added from a plurality of gradation candidates, and outputs it as an image signal of the target pixel. A differencing circuit determines a display error of the target pixel.
