Abstract:
1. An image processor comprising: an image data input unit that inputs input image data including a first predetermined number of pixels; an enlargement processing section that generates output image data including a second predetermined number of pixels more than the first predetermined number, on the basis of the input image data including the first predetermined number of pixels, the enlargement processing section also generates intermediate image data including a third predetermined number of pixels larger than the first predetermined number and smaller than the second predetermined number, on the basis of the input image data input to the image data input unit, including the first predetermined number of pixels; an image processing section that applies image processing to at least one of the input image data, the intermediate image data and the output image data; a controller that controls the image processing section and the enlargement processing section, and an image data output section that outputs the output image data processed by the enlargement processing section and the image processing section; wherein the controller controls the enlargement processing section to generate the intermediate image data, when a calculated value corresponding to a difference between the first and the second predetermined numbers exceeds a reference value which is used at the time of determining whether to generate the intermediate image data and perform the image processing to the intermediate image data; the controller controls the image processing section to apply image processing to the intermediate image data including the third predetermined number of pixels, generated by the enlargement processing section, and the controller controls the enlargement processing section to generate the output image data including the second predetermined number of pixels, on the basis of the intermediate image data including the third predetermined number of pixels, to which the image processing section has applied image processing.
