ABSTRACT:
An image-sensing apparatus has an area sensor1that outputs image data by logarithmically converting the brightness of light incident thereon, a black-level detector2for detecting the black level BL of the image data at which the image data has the lowest signal level, a white-level detector3for detecting the white level WL of the image data at which the image data has the highest signal level, a calculation formula determiner4for determining, in accordance with the detected black and white levels BL and WL, the formula to be used to convert the signal level of the image data, and a dynamic range converter5for converting the signal level of the image data using the calculation formula determined by the calculation formula determiner4.
