    摘要： An image processing apparatus (5) that corrects an input image signal (Xin) pixel by pixel to generate a corrected image signal (Xout), having a filtering means (2) that determines a luminance distribution of a pixel to be corrected and pixels neighboring the pixel to be corrected, a correction gain calculation means (3) that determines the correction gain of the pixel to be corrected, and an operation means (4) that uses the correction gain determined by the correction gain calculation means to perform an operation on the input image signal pixel by pixel. With this simple configuration, the dynamic range of the input image can be appropriately improved.

    摘要： An image capture apparatus which is compact and structurally simple and allows for prevention of a flicker noise, a method of capturing an image which allows for prevention of a flicker noise, and a mobile terminal using the apparatus and the method, are provided. In the image capture apparatus, a vertical cycle is adjusted so as to maintain 20 fps or 20/2m (m is an integer) fps, thereby to prevent a flicker noise in an image as obtained. To this end, in the image capture apparatus, a frequency of a horizontal transfer clock, a horizontal count level and a vertical line count level may be adjusted. Further, a fraction count is provided to adjust the length of one vertical cycle. Moreover, the image capture apparatus may be incorporated in a mobile terminal.

    摘要： An imaging device has color signal generating means (20) for outputting first color signals (R5, G5, B5) corresponding to incident light, and matrix operation means (67) for performing a matrix calculation including multiplication of the first color signals, color signals obtained by raising the first color signals to a power with a first constant (i) as an exponent, color signals obtained by raising the first color signals to a power with a second constant (j) as an exponent, and corresponding matrix coefficients to obtain second color signals (R6, G6, B6). The first and second constants and the matrix coefficients are determined so that the total characteristics of the color signal generating means and the spectral sensitivity characteristic correction means (6) approximate human chromatic curves or spectral sensitivity curves obtained by a linear transformation thereof. Good color reproducibility can be obtained without the use of an infrared cut filter for chromatic correction in the imaging device, and high-sensitivity imaging can be performed under dark conditions.
