In a solid-state imaging device, a plurality of vertical charge transfer paths is arranged at a horizontal pitch A within a photoelectric conversion region, and at a pitch B that is smaller than the pitch A in a portion where the signals are input into the horizontal charger transfer path. A read-out amplifier and a horizontal charge transfer path for receiving signals from vertical charge transfer paths are provided for each photoelectric conversion block into which the photoelectric conversion region has been partitioned. The read-out amplifiers have the same shape and their positional relation is one of parallel displacement in regions that are obtained by changing the pitch of the vertical charge transfer portions. Thus, a solid-state imaging device is achieved that is not so easily influenced by mask misalignments or skewed ion implantation angles, and in which signal read-out at high speeds is possible.

A color filter arrangement (11) is used, in which a plurality of filter units are each made of 2×2 arrangements of red (R), green (G), green (G) and blue (B) color elements. First, signal charges are added up for all pixels belonging to each of a plurality of pixel blocks made of quadratic arrangements of 3×3 of pixels, which are larger than the filter units (2×2 arrangement). Then, compressed color information for each of the pixel blocks is obtained from a result of the addition for each pixel block, taking the 2×2 arrangements of pixel blocks as large filter units.

Gray level data of boundary pixels that are adjacent to a block boundary in a photoelectric conversion section is stored. Then, a cumulative histogram regarding the number of pixels for different gray levels is produced based on the stored gray level data separately for each block, and a data table representing the correspondence between each gray level before correction and that after correction for the block to be corrected is produced so as to reduce the difference between the cumulative histograms. The data table is stored in a correction data RAM. By using the data table, the outputs of the block to be corrected are non-linearly corrected for different gray levels.
