摘要： Provided is an image inputting apparatus wherein luminance signals having a high S/N ratio can be generated even during nighttime with a small quantity of photons. An imaging element images image components. A color signal generating section generates color signals from the image components. A color space conversion section converts the color signals into a color space that includes luminance signals and color difference signals. The color space conversion section calculates a luminance signal obtained by adding the image components, as the luminance signal of the color space to be converted.

摘要： An imaging device is provided with an imaging element. The imaging element has a sensitive wavelength region including an infrared wavelength region, and selectively including a visible wavelength region, and is composed of at least three types of pixels having spectral sensitivities different from each other. The imaging device generates a color image, based on a luminance signal including an infrared wavelength component, and based on a color-difference signal that has been generated based on a visible wavelength component in original image data. The luminance signal including an infrared wavelength component is generated, based on a signal obtained by compressing the dynamic range of original image data including at least three types of original image components acquired by an imaging operation of the imaging element.

摘要： An inflection point variation correction unit 641 executes a predetermined characteristic conversion processing on pixel data read by each pixel, so as to unify the photoelectric conversion characteristic of each pixel data into a linear characteristic. When the flexure start level S of a target pixel, which is one of a plurality of pixels, is greater than a predetermined inflection point threshold, and when, at the same time, the pixel value d of the pixel data read by the target pixel is greater than a predetermined pixel threshold, then an inflection point interpolation unit 642 outputs not a pixel value d′ obtained by the above mentioned characteristic conversion processing, but a pixel value d″ obtained by an interpolation processing using a pixel data read by a neighbor pixel located near the target pixel, whereby the photoelectric conversion characteristic of the pixel data read by the target pixel is converted into the linear characteristic.

摘要： A luminance signal and a color information signal having high S/N ratios are generated by combining a visible luminance image component and an infrared image component at an appropriate ratio according to brightness of a subject such as brightness on a sunny day or brightness in darkness. An image pickup element 3 picks up a ye image component Dye, an R image component DR, an infrared image component DBlk and a luminance image component DW. An evaluation value calculator 41 calculates an evaluation value eDW and an evaluation value eDBlk by adding pixel values of the luminance image component DW and pixel values of the infrared image component DBlk in a local area, and calculates an evaluation value e (=eDW−eDBlk). A factor determiner 51 determines weighting factors k, kw from the evaluation value e. A signal generator 44 weights the luminance image component by the weighting factor k, weights the visible luminance image component by the weighting factor kw, combines the luminance image component and the visible luminance image component to calculate a luminance signal dY, and also calculates color signals dR, dG and dB.
