A device and method are provided for synthesizing pixel values from different exposure time settings to generate a high dynamic range image. The different exposure times are controlled for pixels of the same color constituting a pixel block, and added pixel values are generated which add up the output for the same color pixels in the pixel block. The added pixel values are generated, for example, by a computing unit including an adding unit for adding up the output for the same color pixels in the pixel block. Alternately, the added pixel values are generated by performing floating diffusion (FD) set to pixel block units. In floating diffusion (FD), charges outputted from each of the same color pixels constituting a pixel block are accumulated and outputted. |
