摘要 |
An Apparatus for correcting dark signal of an image sensor (8) comprises: a first A/D converter (2) which converts output signals from the image sensor into digital values, an adder (3) which adds the digital values in dark for each pixel, a memory (1) which stores the data from the adder on the result of the addition, a random number generating means (10) which generates a random number so as to be a mean of the stored data in the memory, and a subtracter (4) which subtracts the random number from the digital values at a time of reading of the images and outputs image data. |
