IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS

An image processing apparatus has an operation panel to display an operation panel image used for editing the virtual object, and capable of receiving a user instruction of editing the virtual object, and an operation panel image generation unit to generate the operation panel image by using the data held in the database. A rendering unit updates data held in the database according to the user instruction and the measurement result of the second measurement unit, and renders, by using the updated data, the image of the virtual object according to the measurement results of the first and second measurement units. A composition unit composites the rendered image of the virtual object and the captured image of the physical space to generate the mixed reality image, and an HMD displays the generated mixed reality image.
