Abstract: To obtain an appropriate exposure condition even in second photographing when generating an image with an expanded dynamic range. An exposure control unit controls an imaging element including a normal pixel for generating an image signal and a low-sensitivity pixel for generating a low-sensitivity image signal and having lower photoelectric conversion sensitivity to visible light than the normal pixel under a predetermined exposure condition and causes the imaging element to output the image signal and the low-sensitivity image signal. A low-sensitivity histogram generating unit generates a low-sensitivity histogram indicating an appearance frequency distribution of the low-sensitivity image signal based on the low-sensitivity image signal. A short-time exposure condition calculating unit calculates a short-time exposure condition with an exposure time shorter than the exposure condition based on the generated low-sensitivity histogram.

Abstract: The present disclosure relates to an imaging apparatus, an imaging method, and a program that allow control of an invisible light component of a captured image without a mechanism that inserts and removes a filter that shields the invisible light component. A luminance composition unit combines a luminance signal of a visible light component of a pixel signal of a captured image including an invisible light component and the visible light component with the pixel signal. A chroma gain amplifier attenuates a chrominance signal of the visible light component. The present disclosure can be applied to an imaging apparatus and the like that include, for example, an optical filter that transmits visible light and infrared light, have pixels in an RGBW array, and perform a Bayer conversion process on a captured image.

Abstract: The present disclosure relates to an imaging apparatus, an imaging method, and a program that enable exposure control on a captured image in a non-Bayer pattern by an exposure control method designed for captured images in Bayer patterns. When a Bayering process is performed on a captured image in an RGBW pixel array, a level correction unit corrects the signal level of the captured image so that an earlier level that is the signal level of each white pixel with the highest sensitivity in the captured image prior to the Bayering process becomes equal to a later level that is the signal level of each green pixel to be used in exposure control on an image in a Bayer pattern that is the RGB image after the Bayering process. The present disclosure can be applied to imaging apparatuses, for example.

A distance detecting unit is configured to detect a distance between the vehicle and the other moving object. A lighting control unit is configured to control the lighting unit on the basis of the distance between the vehicle and the other moving object detected by the distance detecting unit, thereby changing a state of the at least one road irradiation beam.

Abstract: Soft magnetic material elements are provided on both sides of each of magneto-resistance effect elements with a spacing therebetween. As a result, an external magnetic field generated from a magnet can be pulled to above a substrate on which the magneto-resistance effect element is provided, thereby making it possible to amplify the external magnetic field to be applied to the magneto-resistance effect element to more than in the related art. Since a bias magnetic field is applied to a free magnetic layer, a magnetic sensor is resistant to a disturbance magnetic field. Moreover, since the external magnetic field applied to the magneto-resistance effect element can be amplified, even if the bias magnetic field is applied to the free magnetic layer, the magnetic detection sensitivity can be apparently improved to more than in the related art, thereby increasing the output.
