| abstract | (57) [Abstract] [Purpose] An object of the present invention is to provide a line-of-sight detection device capable of shortening the time required for the main accumulation operation at the time of line-of-sight detection. [Configuration] Preliminary accumulation and main accumulation for simultaneously obtaining the peak value in each column and row direction of the image sensor and the average value of the pixels in each block divided into a plurality are started at the same time, and after the preliminary accumulation is completed, the main accumulation is performed. Accumulation is continuously performed, and in parallel with this, the nondestructively preliminarily accumulated signal is read out to obtain the peak value and the average value of the pixels in the block. Then, using this peak value and the average value of the pixels in the block, the AGC operation such as setting the accumulation time of the main accumulation is performed during the main accumulation operation. Further, the main accumulation operation is started immediately after the AGC accumulation / image signal reading is completed, and the AGC operation such as setting the accumulation time of the main accumulation is performed during the main accumulation operation. |
