, which includes a developing belt and a developing roller, is well known. The developing belt provides an electrostatic latent image formed on a photosensitive drum with toner to form a toner image thereon. The developing roller supplies the developing belt with the toner and scrapes residual toner, which does not contribute to forming the toner image, off the developing belt. A voltage for supplying the developing belt with the toner is applied to the developing roller. Japanese Patent Laid-Open No. 07-134646 discloses one such developing device.
In the aforementioned belt-type developing device, however, the residual toner cannot be fully removed from the developing belt, thereby forming a residual image caused by the residual toner on a sheet. This will cause adverse effects on print quality. Digital video capabilities can be incorporated into a wide range of devices, including digital televisions, digital direct broadcast systems, wireless broadcast systems, personal digital assistants (PDAs), laptop or desktop computers, digital cameras, digital recording devices, video gaming devices, video game consoles, cellular or satellite radio telephones, and the like. Digital video devices implement video compression techniques, such as those described in standards defined by MPEG-2, MPEG-4, or ITU-T H.264/MPEG-4, Part 10, Advanced Video Coding (AVC), or other standards, to transmit and receive digital video information more efficiently. Video compression techniques may perform spatial prediction and/or temporal prediction to reduce or remove redundancy inherent in video sequences.
Intra-coding relies on spatial prediction to reduce or remove spatial redundancy between video blocks within a given coded unit. Inter-coding relies on temporal prediction to reduce or remove temporal redundancy between video blocks in successive coded units of a video sequence. For inter-coding, a video encoder performs motion estimation and compensation to identify, in reference units, prediction blocks that closely match blocks in a unit to be encoded, and generate motion vectors indicating relative displacement between the coded blocks and the prediction blocks. The difference between the coded blocks and the prediction blocks constitutes residual information. Hence, an inter-coded block can be characterized by one or more motion vectors and residual information.
In some coding processes, motion vectors may have fractional pixel values that permit a video coder to track motion with higher precision than integer pixel values. To support identification of prediction blocks with fractional pixel values, an encoder applies interpolation operations to a reference unit to produce values at sub-pixel positions, such as quarter-pixel or half-pixel positions. The H.264 standard specifies the use
, which includes a developing belt and a developing curler, is well known. The modernize belt provides an electrostatic latent prototype form on a photosensitive drum with toner to shape a toner image thereon. The developing curler provide the developing knock with the toner and scrapes residual toner, which does not contribute to form the toner image, off the developing belt. A voltage for supplying the develop belt with the toner is applied to the break roller. Japanese Patent Laid - Open No. 07 - 134646 discloses one such developing device. 
 In the aforesaid belt - character developing device, however, the residual toner cannot be fully removed from the developing swath, thereby forming a residual image caused by the residual toner on a sheet. This will cause adverse effect on photographic print quality. Digital video capabilities can be incorporated into a wide range of devices, including digital television, digital direct broadcast systems, wireless broadcast system, personal digital assistant (personal digital assistant), laptop or desktop computers, digital cameras, digital recording devices, video gaming devices, video plot consoles, cellular or satellite radio telephones, and the like. Digital video devices implement video compression techniques, such as those described in standards define by MPEG-2, MPEG-4, or ITU - T H.264 / MPEG-4, Part 10, Advanced Video Coding (AVC), or early standard, to transmit and receive digital video information more efficiently. Video compression techniques may do spatial prediction and/or temporal prediction to deoxidize or remove redundancy inherent in television sequences. 
 Intra - coding relies on spatial prediction to dilute or remove spatial redundancy between video engine block within a given code unit. Inter - coding relies on worldly prediction to reduce or remove worldly redundancy between video blocks in successive coded units of a television sequence. For inter - coding, a video encoder performs motion estimation and compensation to identify, in reference units, prediction block that closely match block in a unit to be encoded, and generate motion vectors indicating proportional displacement between the coded blocks and the prediction blocks. The difference between the coded blocks and the prediction blocks form residual data. therefore, an inter - coded block can be characterized by one or more apparent motion vectors and residual information. 
 In some code processes, motion vectors may suffer fractional pixel value that permit a video programmer to track motion with higher precision than integer pixel values. To support identification of prediction engine block with fractional pixel values, an encoder applies interpolation operations to a reference unit to grow values at sub - pixel positions, such as quarter - pixel or half - pixel positions.
