摘要： An apparatus and method for performing automatic exposure and gain control while minimizing oscillations as well as providing a good response time, for example, a lag time or a settling time of about one frame. The automatic exposure and gain controls are performed not only on the image as a whole but on a weighted region of interest. If the contrast in the image exceeds the dynamic range of the sensor array, then the image in the region of interest will improve at the expense of the remainder of the image. A region of interest is a selected subset of tiles upon which automatic exposure and gain control will be based. The tiles are defined by a grid system having grid coordinates, which are programmable. Image sensors have to receive feedback with regular updates of exposure and gain settings based on ever changing light conditions.

摘要： A method is described for detecting brightness signals from a multiplicity of light-sensitive sensor elements, in particular CCD lines or arrays, in which the brightness signals are amplified in such a way that an A/D converter which digitizes the amplified brightness signals works in its permissible working range. For the brightness signal of a predetermined sensor element, the gain is reduced in steps, preferably in binary steps, from a maximum gain factor down to a working value at which the A/D converter works in the permissible working range. For each following sensor element, the working value of the respective preceding sensor element is used as the maximum gain factor. The number of changeover operations of the amplifier is considerably reduced and thus the detection time is shortened.

摘要： The present invention provides a gray-scale transformation processing device which reduces the memory capacity for an LUT, and carries out gray-scale transformation with high accuracy. The gray-scale transformation processing device includes a data dividing unit, a lookup table, a transform function generating unit, and a gray-scale transforming unit. The data dividing unit divides digitally inputted image data into high-order bits data and low-order bits data. In the lookup table, the correspondences between the high-order bits data and correction coefficient groups providing transformation curves, respectively, are stored. The transform function generating unit generates a high-order gray-scale transform function from the correction coefficient group obtained from the lookup table. The gray-scale transforming unit calculates the low-order bits data with the gray-scale transform function to output image data, which has been subjected to gray-scale transformation.
