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.

摘要： An imaging system controller (5) outputs a control signal (VC). The control signal (VC) gives a command to output driving clocks (φVn, φHm) of an imaging element (1) in a signal transmission period, and a command to suspend output of the clocks (φVn, φHm) in an idle period subsequent to the signal transmission period. The length of the idle period is a multiple of the length of the signal transmission period by a natural number. The imaging system controller (5) periodically repeats output of the control signal (VC) giving these commands a number of times corresponding to the number of horizontal lines of the imaging element (1). In response to the commands of the control signal (VC), a timing generator (2) generates and outputs the clocks (φVn, φHm), and suspends generation and output of the same. An imaging device (10) thereby intermittently drives the imaging element (1), to generate and output a picked-up image signal (V2).

摘要： A regression analysis is carried out (8) using pixel signals having a K-th spectral characteristic as the explanatory variable and pixel signals having an L-th spectral characteristic as the purpose variable in a plurality of pixel positions in an area neighboring a pixel of interest to obtain a pixel signal having the L-th spectral characteristic (9). Pixel signals obtained by low-pass filtering (7a-7c) of the output signals of an imaging device may be used as the explanatory variable and the purpose variable. The occurrence of false colors is thereby reduced when, in a group of pixel signals from pixels arrayed on a two-dimensional plane, each pixel having one of a plurality of spectral characteristics, the missing colors at each pixel position are obtained by interpolation.

摘要： A first LUT composed of table values of brightness of N subjects determined in such a manner that the integrated value is made to be constant and a second LUT composed of table values of N charge storage time periods corresponding to the table values of the brightness of the N subjects are provided. When an image has been picked up with charge storage time at an n-th address in the second LUT, integrated value &Sgr; obtained by the calculating means 6 is divided by the n-th charge storage time S so that the brightness L of the subject is calculated. The charge storage time S corresponding to the calculated brightness L of the subject is selected from the first and second LUT so that exposure is controlled.
