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.

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.

A manufacturing device for a synthetic resin hollow molded body molds a first split assembly member, a second split assembly member, and a third split assembly member by a first injection, and joints each of contact portions of the three members with a corresponding contact portion by a second injection. The manufacturing device includes an ejecting mechanism which moves the second split assembly member in a die opening/closing direction, a rotating mechanism which rotates the third split assembly member around a shaft center in the die opening/closing direction, and a sliding mechanism which slides the second split assembly member and the third split assembly member in a direction perpendicular to the die opening/closing direction. According to the manufacturing device, while the dies are open after the first injection, the three members are made different by the ejecting mechanism, and then the three members are made to face one another by the rotation mechanism and the sliding mechanism in the die opening/closing direction.

A filter has a first case member and a second case member that are mutually joined to form a filter chamber, and a filter element that is held between respective joining ends of the first case member and the second case member. The first case member has laser permeability, and the second case member has laser absorbency. An element weld is formed by laser light on a contact area between the joining end of the second case member and the filter element.
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 vehicle motion control device reduces noise resulting from operation of a vacuum booster when an automatic pressure control is performed by properly controlling the energization of a linear solenoid of a booster actuator. An automatic hydraulic pressure generator is controlled in accordance with the vehicle motion condition and a hydraulic pressure control valve device is controlled to perform the automatic pressure control. A target electric current of the linear solenoid for actuating the vacuum booster is instantaneously increased to a starting target value which corresponds to an electric current value immediately before starting the operation of the vacuum booster and which is less than a maximum value of the target electric current, and then is gradually increased approximately to the maximum value of the target electric current.

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.
