There is provided an image processing apparatus that outputs projection image data to a projection unit configured to display an image by projecting a projection image onto a print image at a projection plane. A first acquisition unit acquires image data. A second acquisition unit acquires parameters related to reflectances at a plurality of positions on the print image. A setting unit sets an offset value for performing offset adjustment of at least one color of the image at the projection plane. A correction unit configured to generate the projection image data by correcting a pixel value of a pixel in the image data based on the offset value and the parameter at a position in the print image that corresponds to the pixel.

To obtain an excellent edge enhancement effect even when dynamic &#x3b3; correction processing is executed for an edge-enhanced image signal, and to obtain an excellent edge enhancement effect for various &#x3b3;-characteristics. An edge component is detected from an input image signal. A &#x3b3; correction curve is calculated based on characteristics of an image scene detected by a scene characteristic detector, and its data is stored in a dynamic &#x3b3; correction RAM table and an inverse gradient RAM table. A gain controller multiplies the edge component by a control signal from the inverse gradient RAM table to generate an edge enhancement signal which is in turn added to the image signal to obtain an edge-enhanced signal. The inverse gradient RAM table sends an inverse number of a gradient of a &#x3b3; correction curve corresponding to a signal level of the inputted image signal as the control signal to the gain controller. An edge-enhanced signal becomes an image signal for which dynamic &#x3b3; correction is performed in accordance with a dynamic &#x3b3; correction RAM table to be outputted.
