摘要： An image input apparatus can acquire an image with a high contrast without saturating a camera output even for a subject having a large light and dark difference while achieving a wide dynamic range. An image sensor has an input-output characteristic varying with a plurality of regions delimited according to a difference in the amount of incident light. A video luminance signal level is detected from a video signal of the image sensor. An amount of light on a screen is calculated from the image luminance signal level. The image sensor is adjusted to make the amount of light on the screen coincide with a target light amount. The target light amount is set such that a relation between the target light amount R and an amount of light Q at a change point that is at the lowest luminance in an input-output characteristic of the image sensor satisfies R

摘要： An imaging apparatus of a wide dynamic range can be achieved at low cost while making improvement in contrast and the maintenance or reduction of a circuit size compatible with each other. The apparatus includes a photoelectric conversion part that converts a signal from a light receiving element into a voltage in accordance with an amount of incident light, an analog signal processing part that processes an analog video signal output from the photoelectric conversion part, an A/D conversion part that converts the analog video signal into a digital video signal, and a high frequency emphasis part that emphasizes a high frequency component of the video signal. The high frequency emphasis part suppresses a low frequency component of brightness in the video signal to emphasize the high frequency component, whereby image data of good contrast can be obtained while keeping a dynamic range of the signal.

摘要： A passenger protection apparatus of a simple construction is capable of stably performing air bag control and preventing erroneous control due to objects such as passenger's hands, newspapers, etc., other than passenger' head. A collision detection part detects a collision of a vehicle, and an object detection part detects an object in a prescribed object detection area rearwardly of an air bag installation surface in the vehicle based on a signal from a sensor. An air bag control signal generation part controls the expansion of an air bag based on the detection results of the object detection part and the collision detection part. The air bag control signal generation part makes the air bag control signal into an expansion permission signal only when an object exists in the object detection area at the time of detection of the collision or within a predetermined time from the detection of the collision.
