A vertical selection circuit selects a selection line, a first shutter line, and a second shutter line so that one frame is divided into three parts at arbitrary ratios. For example, if one frame including 500 lines is divided such that the interval from the first shutter line to the second shutter line includes 400 lines and the interval from the second shutter line to the selection line includes 5 lines, then an output signal generated during a period from the first shutter line to the second shutter line provides an image which is formed over a long storage period and in which a low-luminance area is clearly represented, while an output signal generated during a period from the second shutter line to the selection line provides an image which is formed in a short storage period and in which a high-luminance area with a dynamic range of as large as 80 is represented without encountering saturation. By mixing the two output signals described above, an image with a large dynamic range can be obtained.
A solid state imaging apparatus comprising:
A method of driving a solid state imaging apparatus, said solid state imaging apparatus comprising a pixel array including a plurality of pixels arranged in a matrix fashion, vertical selection means for sequentially selecting horizontal lines of pixels in the pixel array line by line in a vertical direction, and signal processing means for processing signals output from the pixels selected by the vertical selection means, said method comprising the steps of:
