Image processing device, image capturing device, and program

This image processing device comprises: an image acquisition section that acquires a plurality of images of a subject captured at different timings, the subject being irradiated with light that has been intensity-modulated by a plurality of modulation frequencies or modulation frequency bands; and a demodulation section that generates, pixel by pixel, a plurality of pieces of pixel information indicating the amount of light from the subject caused by various light having been intensity-modulated by said plurality of modulation frequencies or modulation frequency bands by demodulating, pixel bypixel, pixel values in the plurality of images by a plurality of demodulation frequencies or demodulation frequency bands based on said plurality of modulation frequencies or modulation frequency bands. 图像处理装置具备：图像获取部，其获取在不同时间拍摄被摄体而得到的多个图像，其中，对被摄体照射了以多个调制频率或调制频带进行强度调制后的光；和解调部，其针对多个图像的像素值以基于多个调制频率或调制频带的多个解调频率或解调频带针对每个像素进行解调，由此按每个像素生成多个像素信息，该多个像素信息表示基于以多个调制频率或调制频带进行强度调制后的各个光的来自被摄体的被摄体光量。
