摘要： A fingerprint sensor used for a fingerprint recognition system comprises a first prism or prism array including a first surface which a human finger is placed and a second surface; a lamp for irradiating the finger with light; a second prism or prism array for refracting the light which is reflected from the finger and subsequently passes through the second surface in such a way that the light refracted by the second prism or prism array travels along a path closer to a normal to the first surface of the first optical component than a path of light without refraction by the second prism or prism array; and an image sensor for receiving the light refracted by the second prism or prism array and converting fingerprint information for the finger into an electric signal.

摘要： The color video camera has a processing circuit which converts electrical signals obtained from an imager into a luminance signal and color-difference signals. The color video camera further includes a memory which stores a table of values designating color saturation levels and corresponding to a specific hue of a background color. The memory outputs a color saturation level based on the color difference signals obtained by imaging an object on a background of the specific hue. This color saturation level is compared with the luminance signal, and based on the comparison results the luminance signal and color difference signals are separated into components corresponding to the background area and components corresponding to the object area.

摘要： The difference between the output of a k-signal nonlinear low-pass filter (8g) and the output of an h-signal nonlinear low-pass filter (8r) is added (44) to the value of the h-th pixel signal (h(i, j)) at the pixel position of interest to obtain the k-th pixel signal (k(i, j)) at the pixel position of interest. Accurate pixel interpolation can be performed with good noise immunity, even at locations where the color signals are uncorrelated.

摘要： A pixel signal having a k-th spectral characteristic at a pixel interpolation position occupied by a pixel signal having an h-th spectral characteristic is generated from a set of pixel signals arrayed in a two-dimensional plane, each having one of a plurality of spectral characteristics, by calculating a difference between low-frequency components, corresponding to a degree of correlation between pixel signals having the k-th and h-th spectral characteristics in a neighborhood of the pixel interpolation position (8r, 8g, 8b, 24k, 24h, 26), calculating a non-correlation value corresponding to a degree of non-correlation between the pixel signals having the k-th and h-th spectral characteristics in the neighborhood of the pixel interpolation position (7r, 7g, 7b, 23k, 23h, 25), and obtaining the pixel signal having the k-th spectral characteristic at the pixel interpolation position by using the calculated difference and the non-correlation value (27, 28, 29). Accurate interpolation can be performed despite various different correlation relationships between color component values.

摘要： An image pickup apparatus includes a solid-state imaging device, an accumulating section, first and second imaging parameter setting sections, a calculating section, a flicker detecting section, and a switching section. The accumulating section calculates a projection output value of a predetermined line in a frame. The calculating section calculates inter-frame variations of the projection output values, and calculates a flicker index from the variations of a predetermined number of frames. The flicker detecting section detects the flicker from the index, and controls the switching section in response to the detection result of the flicker, so that the switching section selects either the setting signals from the first imaging parameter setting section or the setting signals from the second imaging parameter setting section. Thus, the charge storage time of the solid-state imaging device is set at either an integer multiple of 1/100 second or an integer multiple of 1/120 second in response to the frequency (50 Hz or 60 Hz) of a power supply of the fluorescent lighting. The image pickup apparatus can solve a problem of a conventional apparatus in that it is difficult for the conventional apparatus to suppress the flicker in regions where the frequency of the power supply differ from each other.

摘要： A spectroscope (2) spectrally separates a light from a light source (3) and outputs the separated light from an emitting terminal (6) thereof. An image pick-up device (1) having a solid-state image sensor picks-up an image of the emitting terminal (6). First operation means (7) performs a correction to each of plural image signals corresponding to plural pixels that are outputted by the image pick-up device (1) so that a gradation characteristic of the image pick-up device (1) is corrected from non-linearity to one closer to linearity. Second operation means (8) calculates, as a spectral responsivity characteristic for the separated light, a mean value of the plural image signals after the correction by averaging the same over a certain range within the plural pixels. As a result, the spectral responsivity characteristic of the image pick-up device (1) is measured precisely.

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.
