    摘要： In an image forming apparatus, an image forming unit includes a movable member that is rotationally driven by a driving unit. A moving distance or a moving speed of the movable member is detected. The driving unit is controlled based on a quantity of control. An occurrence of a detection error or a control error is determined based on the moving distance, the moving speed, or the quantity of control. A predetermined error process is executed if an error occurs.

    摘要： For the purpose of efficient transmission based on the UWB system, first and second baseband waveforms are generated at a cycle equivalent to an integral multiple of a carrier to have a specified phase difference from each other. The first baseband waveform is multiplied by the carrier and a first transmission data sequence to acquire a first transmission waveform. The second baseband waveform is multiplied by a phase shifted carrier and a second transmission data sequence to acquire a second transmission waveform. The first transmission waveform is mixed with the second transmission waveform to acquire a transmission signal. The transmission signal is transmitted as a π/2 shift BPSK signal to transmit a UWB signal. Selecting the baseband waveforms and the carrier makes it possible to configure the transmission band and easily provide division multiplexing transmission.

    摘要： A compression and de-compression arrangement is provided for a display device having a display memory and a display. The arrangement includes a color processor which reduces the color samples by processing a pair of pixels to produce first and second luminance values and forming first and second output chrominance values from the pair of pixels. The first and second output chrominance values are formed by calculating for each pixel the corresponding U and V chrominance values and forming the first and second chrominance values (U, V) from the average of the values for each pixel.Forming the compressed representation of the color image provides an advantage when recovering the original image, particularly for example where the image contains detail and/or text. The image processing apparatus of the system receives the group of color component signal samples from the display memory and generates first and second output pixels, each comprising three color component values (R, G, B), from each group. The image processing apparatus includes a detail detection processor, which detects whether either of the pixels represented by each group of signal samples represents white or black and the other does not. This may be representative of one of the pixels being part of a text character or detail. Accordingly, in order to improve the likelihood of preserving the text and detail in the reproduced image, the de-compressing processor is arranged to assign the chrominance values (U1, V1) of one of the pixels to zero. The other chrominance value (U2, V2) of the other pixel is assigned the value of twice the value of the first and second input chrominance values respectively.
