A color filter is constituted by unit arrays of two columns and four rows of filter elements. The first column has cyan, magenta, cyan, and green (or green, yellow, green and cyan) filter elements which are arranged in that order and the second column has yellow, green, yellow, and magenta (or magenta, cyan, magenta and yellow filter elements which are arranged in that order. A solid state image apparatus having an expanded dynamic range is realized by using this color filter in that the dynamic range of the photoelectric elements corresponding to the green filter elements can be utilized more efficiently.

Color filter having cyan, yellow, green and magenta filter elements

A method for driving a solid-state image sensor in which the bias charges in a horizontal readout CCD (charge-coupled device) shift register are transferred onto vertical signal lines with the signal charges and then the signal and bias charges are transferred back into the horizontal readout CCD shift register from which are read out the signal charges (generated at the photosensor or photodiodes).

Method for driving solid-state image sensor

Solid state color imaging apparatus comprises a solid state photoelectric device such as an interline type CCD having a color filter in front of it. The color filter has a number of minute filter elements disposed forming vertical column and at the same time horizontal rows,

In a solid state color imaging apparatus comprising

A surface of a semiconductor substrate is coated with a mask having a desired doping pattern and the ions of a desired element are accelerated using the mask so that the structure of a predetermined region is changed. Thereafter the doped region or the region not doped is etched and removed.

Method for machining surfaces of semiconductor substrates

An improvement in optical remote-control apparatus which comprises a light-beam transmitter and a light-receiver, wherein the improvement is that a light-scattering (i.e., light-diffusing) plate having a suitable area is provided in front of the light-receiver, so that the aiming tolerance of the light-beam transmitter becomes broader, enabling easy remote-control.
