摘要： A first image sensor receiving light from a subject and a second image sensor capable of receiving light of the same image as the first image sensor and having a spectral sensitivity characteristic different from that of the first image sensor are provided. A color-correcting coefficient determining part calculates, based on each output value photoelectrically converted in the first and the second image sensors, a color-correcting coefficient with which a color-correcting part performs color correction on the output value of the first image sensor. Using the first and the second image sensors of different spectral sensitivity characteristics, parameters for receiving/recognizing light from a subject field can be easily increased to obtain a favorable color reproduction characteristic. Since applying the image-processing device to a conventional electronic camera including the first and second image sensors only requires a change in signal-processing method, it can be easily applied to an existing electronic camera.

摘要： An image processing device of the present invention includes a color-gamut determining part, a color-space determining part, and a color-space conversion part. The color-gamut determining part determines a color gamut as a range of color distribution from input image data. The color-space determining part determines a color space substantially covering the color gamut determined by the color-gamut determining part. The color-space conversion part converts the input image data into such image data that is rendered in the determined color space. The colors of the subject can thus be reproduced accurately from the converted image data.

摘要： A microlens condenses incident light to an opening. Light passed through the opening reaches a first dichroic mirror. The first dichroic mirror passes blue light and reflects green and red light. Only the blue light is incident on a first light receiving surface. The first dichroic mirror leads the green and red light to a second dichroic mirror. The second dichroic mirror passes the green light and reflects the red light. Only the green light is incident on a second light receiving surface. The second dichroic mirror leads the red light to a third dichroic mirror. The third dichroic mirror reflects the red light. Therefore, the red light is incident on a third light receiving surface.

摘要： The present invention provides a gray-scale transformation processing device which reduces the memory capacity for an LUT, and carries out gray-scale transformation with high accuracy. The gray-scale transformation processing device includes a data dividing unit, a lookup table, a transform function generating unit, and a gray-scale transforming unit. The data dividing unit divides digitally inputted image data into high-order bits data and low-order bits data. In the lookup table, the correspondences between the high-order bits data and correction coefficient groups providing transformation curves, respectively, are stored. The transform function generating unit generates a high-order gray-scale transform function from the correction coefficient group obtained from the lookup table. The gray-scale transforming unit calculates the low-order bits data with the gray-scale transform function to output image data, which has been subjected to gray-scale transformation.

摘要： A color photographing device is equipped with a light-receiving section having a red pixel selectively receiving red light and outputting a red pixel signal and a green pixel selectively receiving green light and outputting a green pixel signal. The color photographing device is further equipped with an optical filter disposed on the side with a light-receiving surface of the light-receiving section. The optical filter substantially equalizes the signal level of the red pixel signal and the signal level of the green pixel signal when achromatic color illuminated by a solar light source in the daytime is photographed. Therefore, a white balance gain Wr at about 5000K can be lowered as compared with a conventional color photographing device. Accordingly, reduction of color noises and enhancement of gradation can be expected.
摘要翻译：彩色摄影装置配备有具有选择性地接收红光的红色像素并输出红色像素信号的光接收部分和选择性地接收绿色光并输出绿色像素信号的绿色像素。彩色摄影装置还配备有设置在光接收部分的光接收表面的一侧的滤光器。当在白天被太阳能光源照射的无彩色被拍照时，滤光器基本均衡红色像素信号的信号电平和绿色像素信号的信号电平。因此，与传统的彩色摄影装置相比，大约5000K的白平衡增益Wr可以降低。因此，可以预期颜色噪声的减少和渐变的提高。
