1. An image processing apparatus which generates a display image using an image picked up by an imaging apparatus and causes a display apparatus to display the display image, the image processing apparatus comprising: a reception section configured to receive at least part of each of data of a non-processed image outputted from an imaging device, data of a colored image obtained by performing a demosaicing process and a correction process for the non-processed image and process information acquired in the course of generation of the colored image from the imaging apparatus; a demosaicing section configured to perform a demosaicing process and a correction process for the data of the non-processed image to generate a colored image; and a display image generation section configured to generate a display image using the colored image generated by the demosaicing section and a colored image transmitted from the imaging apparatus, wherein the demosaicing section utilizes the process information transmitted from the imaging apparatus in the course of at least one of the demosaicing process and the correction process.
