Image sensing apparatus with exposure controller

In an imaging apparatus, an imaging unit generates an acquired image of a subject. A luminance information acquirer acquires the subject's luminance information. A detector detects the subject's luminance range on the basis of the acquired luminance information. An imaging controller sets a range of exposure control values having a step that corresponds to a value obtained by multiplying the detected luminance range by a predetermined coefficient k (where 0&#x3c;k&#x3c;1), and then uses the imaging unit to take multiple shots (i.e., multiple imagings) set with respectively different exposure control values within the range of exposure control values. An image compositor generates a composite image by compositing image portions extracted from the plurality of images obtained via the multiple shots. When just one shot is taken, the single exposure control value set for the one shot is contained within the range of the exposure control values.

Imaging signal obtained through exposure for divided exposure times is A/D converted to digital imaging signal. Dark current component is subtracted from the digital imaging signal. The result of subtraction is accumulated and stored in a first memory. Next, exposure for divided exposure times is performed with the imaging device shielded from light. The obtained imaging signal is A/D converted to digital imaging signal. Dark current component is subtracted from the digital imaging signal. The result of subtraction is accumulated and stored sequentially in a second memory. The digital imaging signal stored in the second memory is subtracted from the digital imaging signal stored in the first memory. Then the result of subtraction is output. The word length allocated to one pixel in the first and second memories is longer than the word length of one A/D converted pixel.
