摘要: Disclosed herein is a photographing device that comprises a plurality of light-receiving elements (8a to 8h), a plurality of vertical transfer registers (7a, 7b), a first drive-voltage applying electrode (3a, 3b), and a second drive-voltage applying electrode (1 to 2c). The light-receiving elements (8a to 8h) are arranged in a horizontal direction and a vertical direction. The vertical transfer registers (7a, 7b) transfers the electric charges accumulated in the light-receiving elements in the vertical direction. The first drive-voltage applying electrode (3a, 3b) are arranged parallel to the vertical transfer registers, for applying a drive voltage to a specific one of the vertical transfer registers. The second drive-voltage applying electrode (1 to 2c) is arranged perpendicular to the vertical transfer registers, for applying a second drive voltage to the vertical transfer registers at the same time. The electric charges accumulated in the light-receiving elements are transferred to the vertical transfer registers, due to the voltage output from the first drive-voltage applying electrode or the second drive-voltage applying electrode, or the voltages output from both electrodes. Therefore, the light-receiving elements can have different sensitivities, and the photographing device can photograph dynamic scenes in a broad dynamic range.

摘要: The invention pertains to solid-state imaging devices and methods of operating the imaging devices for imaging objects having a wide dynamic range of illumination levels. The imaging device preferably comprises a two-dimensional array of photosensors, such as photodiodes, arranged in columns and even and odd rows. The photosensors accumulate signal charges corresponding to the incident light flux for an accumulation time. In one embodiment, the even and odd rows accumulate signal charges for different accumulation times. The signal charges from adjacent rows and the same column are preferably summed. In addition, the accumulation times for the even and odd rows preferably alternate between a first and a second accumulation time. Alternatively, alternate image fields acquire signal charge for alternating accumulation times. The longer accumulation time is set so that one or more of the photosensors saturates.

摘要: Un réseau (10) de capteurs comprend un circuit (12) de commande de sensibilité adaptable permettant d'obtenir des sorties multiples à différents niveaux d'exposition. Ceux-ci sont combinés pour produire une sortie à plage dynamique augmentée. On peut réduire cette plage dynamique augmentée d'une manière retenant de préférence les informations de bordure afin de maintenir un fort contraste.

摘要: Described herein is a method of increasing the dynamic range of pixels in an imaging sensor. Two image captures are performed, one at a first short integration time ( T 1 ) and one at a second optimum integration time ( T 1 , T 2 , T max ). An electrical value (V A (1), V B (1), V c (1)) obtained from a pixel or group of pixels at the first short integration time ( T 1 ) is used to predict the second integration time ( T 1 , T 2 , T max ) using a comparison with a set of reference values (V t (i)). The reference values (V t (i)) are related to a saturation electrical value ( V sat ) for each pixel or group of pixels to predict the second integration time ( T 1 , T 2 , T max ). The first short integration time ( T 1 ) is determined as a fractional multiple of the saturation electrical value ( V sat ), and the second integration times ( T 1 , T 2 , T max ) are such that there is no saturation of the pixel or group of pixels. Adjustments can be made to the reference values to allow for offset immunity and variability in light levels during the second integration time.

摘要: In a vehicle-mounted camera system, an appropriate white balance correction processing according to a situation is executed to a long exposure time image and a short exposure time image shot in variously changing illumination environments. A vehicle-mounted camera system (100) includes a vehicle-mounted camera (10) that performs relatively long exposure time shooting and short exposure time shooting, a signal processing device (20) (signal processing device) that executes a white balance correction processing for each of a long exposure time image and a short exposure time image, composes these images after the white balance correction processing, and generates a high dynamic range image, and a system control part (40) (processing switch device) that obtains an illumination environment in which the vehicle is placed, and switches the white balance correction processing for the long exposure time image and the white balance correction processing for the short exposure time image according to the illumination environment.
