A linear filter unit is provided with a plurality of taps and subjects an equalizer input signal to an equalization process so as to output a filter output signal. A DFE unit is provided with a plurality of taps and subjects the filter output signal to an equalization process according to decision feedback so as to output an equalizer output signal. An LMS algorithm unit computes tap coefficients of the linear filter unit and the DFE unit. A determination unit compares a plurality of received power levels corresponding to a plurality of propagation delays in input delay profile data with a threshold level, selects received power levels equal to or higher than the threshold levels and determines a maximum time corresponding to one of the selected power levels.

An image signal processor includes a controller configured to generate a red output signal, a green output signal, a blue output signal and a fourth color output signal in accordance with image input signals. A fourth color light component enables to reproduce a color outside the range of a color reproducible by the red light component, the green light component and the blue light component. The controller generates the fourth color output signal on the basis of a reference signal corresponding to a color different from a complementary color of a color reproduced by the fourth color light component.

This invention relates to a handy sketching apparatus which has an image information reading function and a sketching function to draw an image on the basis of the image information read by the image information reading function, and which is easy to operate and easy to be miniaturized for smaller size.The handy sketching apparatus comprises a base block containing a progressive scanning image information reading mechanism through the bottom face, a sheet carrying path provided on the top side of the base block so as to carry a sheet in a specified direction substantially parallel to the bottom face of the base block, and an upper block integrally formed on the top side of the base block, straddling the sheet carrying path. The image information reading mechanism reads image information placed under the base block sequentially as the apparatus is moved in a sub-scanning direction. The upper block houses a traveling mechanism which is run back and forth in a main scanning direction across the sheet carrying path, thereby moving a drawing utensil to draw an image on the sheet on the sheet carrying path, on the basis of the image information read by the image information reading mechanism.
