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： A lane recognition image processing apparatus can improve lane marking recognition performance by preventing false detection by addition of a condition without changing the basic principle of an one-dimensional image filter. A search area is set for each lane marking with respect to images stored in a image storage part through a window. A candidate point extraction part extracts candidate points of each lane marking from the search area thus set. A lane marking mathematical model equation is derived by approximating sets of extracted candidate points by a mathematical model equation. The candidate point extraction part includes a kernel size setting part, a filtering part that outputs, as a filtering result, the smaller of differences between the gray value of a pixel of interest and those of pixels forwardly and rearwardly apart a kernel size from the pixel of interest in a scanning direction, respectively, and a binarization part that binarizes the filtering result.

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.
