An imaging apparatus comprising: first converging means adapted to converge incident light from a subject; transmitting means (33, 34) adapted to transmit and to make parallel the incident light converged by the first converging means; splitting means (35, 36) adapted to transmit, at a predetermined transmittance, the incident light made to be parallel light by the transmitting means, and also split the non-transmitted part of the incident light made to be the parallel light to the right and left as right and left half-circle sections of the incident light; second converging means adapted to converge the incident light which has been transmitted by the splitting means; first imaging means adapted to image a basic image of the subject, by converting the incident light converged by the second converging means into electric signals; respective left and right third converging means (38-1, 38-2) adapted to converge a respective one of the half-circle sections of the incident light split by the splitting means; respective left and right second imaging means (40-1, 40-2) adapted to image disparity detection images having disparity with respect to each other, by converting a respective one of the incident light converged by the respective left and right third converging means into electrical signals; and respective left and right disparity image generating means (44-1, 44-2) adapted to generate disparity images so as to perform stereoscopic imaging of the subject, by generating respective images with the same point of view as the respective disparity detection images, based on the respective disparity detection image and the basic image; wherein the respective left and right disparity image generating means are adapted to generate the respective disparity images, by taking a pixel of the disparity image to be generated as a pixel of interest, and obtaining a pixel value of the pixel of interest, based on a pixel value of the pixel in the basic image corresponding to the pixel of the disparity detection image which is at the same position as the pixel of interest. first converging means adapted to converge incident light from a subject; transmitting means (33, 34) adapted to transmit and to make parallel the incident light converged by the first converging means; splitting means (35, 36) adapted to transmit, at a predetermined transmittance, the incident light made to be parallel light by the transmitting means, and also split the non-transmitted part of the incident light made to be the parallel light to the right and left as right and left half-circle sections of the incident light; second converging means adapted to converge the incident light which has been transmitted by the splitting means; first imaging means adapted to image a basic image of the subject, by converting the incident light converged by the second converging means into electric signals; respective left and right third converging means (38-1, 38-2) adapted to converge a respective one of the half-circle sections of the incident light split by the splitting means; respective left and right second imaging means (40-1, 40-2) adapted to image disparity detection images having disparity with respect to each other, by converting a respective one of the incident light converged by the respective left and right third converging means into electrical signals; and respective left and right disparity image generating means (44-1, 44-2) adapted to generate disparity images so as to perform stereoscopic imaging of the subject, by generating respective images with the same point of view as the respective disparity detection images, based on the respective disparity detection image and the basic image; wherein the respective left and right disparity image generating means are adapted to generate the respective disparity images, by taking a pixel of the disparity image to be generated as a pixel of interest, and obtaining a pixel value of the pixel of interest, based on a pixel value of the pixel in the basic image corresponding to the pixel of the disparity detection image which is at the same position as the pixel of interest.
