摘要： A multi-step exposure method using an electronic shutter and a photography apparatus using the same are provided. The photography apparatus includes an image sensor, and a control unit which divides an area of the image into a first area and a second area using brightness information of the acquired image, and controls so that a first row group and a second row group of the second area have different exposure times. As a result, an image with a wider dynamic range is provided.

摘要： A gain controlled amplifier and a cascoded gain controlled amplifier based on the same are disclosed. The gain controlled amplifier includes an operational amplifier for amplifying an input signal, an input resistor connected to an input terminal of the operational amplifier, a feedback resistor connected to an output terminal of the operational amplifier, and a resistor circuit for providing voltages having different levels to the input terminal and the output terminal of the operational amplifier, respectively, according to a digital signal composed of specified bits. The gain controlled amplifier employs an R-2R ladder circuit controlled by a digital signal so as to obtain a gain that is in linear proportion to a decibel scale. Since the R-2R ladder circuit operates with a small resistance value, the chip size of the gain controlled amplifier can be reduced.

摘要： A method and apparatus are provided for detecting traveling characteristics of a mechanical shutter. After performing a reset scan operation on a plurality of pixels of an imaging device, first quantities of light are detected by reading pixels of even rows or odd rows of the imaging device. The imaging device is shielded from light by causing a mechanical trailing curtain included in the shutter to travel. Second quantities of light are detected by reading pixels of rows that are different from the rows read to detect the first quantities of light. Traveling characteristics of the mechanical trailing curtain are obtained based on the first quantities of light and the second quantities of light.
