摘要： Disclosed herein is a photographing device that includes a number of light-receiving elements, a number of vertical transfer registers, a first drive-voltage applying electrode, and a second drive-voltage applying electrode. The light-receiving elements are arranged in a horizontal direction and a vertical direction. The vertical transfer registers transfers the electric charges accumulated in the light-receiving elements in the vertical direction. The first drive-voltage applying electrode is arranged parallel to the vertical transfer registers, for applying a drive voltage to a specific one of the vertical transfer registers. The second drive-voltage applying electrode is arranged perpendicular to the vertical transfer registers, for applying a second drive voltage to the vertical transfer registers at the same time. The electric charges accumulated in the light-receiving elements are transferred to the vertical transfer registers, due to the voltage output from the first drive-voltage applying electrode or the second drive-voltage applying electrode, or the voltages output from both electrodes. Therefore, the light-receiving elements can have different sensitivities, and the photographing device can photograph dynamic scenes in a broad dynamic range.

摘要： The present invention related to an image pickup apparatus which can produce a color and sensitivity mosaic image which can be converted into a color image signal having a wide dynamic range by performing a predetermined image process. Light receiving elements of a CCD image sensor are arranged in a lattice arrangements where attention is paid to the color Green irrespective of the sensitivities. Where attention is paid to the color Red irrespective of the sensitivities, the light receiving elements are arranged on every other line. Also where attention is paid to the color Blue irrespective of the sensitivities, the light receiving elements are arranged on every other line similarly. Consequently, where attention is paid only to the colors of the pixels, the pattern P2 has a Bayer arrangement. A mosaic arrangement of a color is realized by disposing an on-chip color filter on an upper face of the light receiving elements of the CCD image sensor. A mosaic arrangement of a sensitivity is realized by an optical method or an electronic method. The present invention can be applied, for example, to CCD image sensor built in a digital camera.

摘要： An image processing apparatus and method and a recording medium therefor control the occurrence of a change in a hue. The histogram of a luminance signal Y is generated in a first step S1. In a second step S2, the histograms of the luminance signals Y are accumulated to generate a cumulative histogram, and the cumulative histogram is subjected to logarithmic approximation thereby to generate a lookup table (LUT) for correcting luminance signals. In a third step S3, a color-difference signal correction parameter LUT is generated by referring to the LUT for correcting luminance signals. In a fourth step S4, an input luminance signal Y is applied to the LUT for correcting luminance signals thereby to acquire a corrected luminance signal Y0. In a fifth step S5, the input luminance signal Y is applied to a color-difference signal correction parameter LUT so as to acquire a correction parameter k. In a sixth step S6, input color-difference signals Cr and Cb are multiplied by the correction parameter k to acquire corrected color-difference signals Cr0 and Cb0.
