Provided is an image processing apparatus, including, a memory unit that stores an input image and read the input image as first image second images, an acquiring unit that acquires an up-conversion line that is a line of pixels used for up conversion from the first and second images, an up-converting unit that performs up conversion using pixels of the up-conversion line, and generate first and second up-converted images obtained by up converting the first and second images, and a generating unit that writes the first and second up-converted images in first and second memory blocks, reads pixels of the first and second up-converted images written in the first and second memory blocks in a certain order decided according to a scan method of a display device configured to display an output image obtained by up converting the input image, and generates the output image according to the scan method.

Image processing apparatus, image processing method, and program

A luminance signal Ya and a color-difference signal Ua/Va constituting an input image signal is transferred to a frame memory (first memory) in the unit of line synchronously with its horizontal synchronous signal and written therein. A memory TGreads out a read-out request RRQ. The cycle of this request RRQ is a time computed based on a single vertical effective period of an output image signal Sc and the number of lines objective for rate conversion of an input image signal Sa. The luminance signal Ya and color-difference signal Ua/Va are transferred in the unit of line from the frame memory to rate conversion units (second memory) through buffers. There occurs no deflection in this transfer cycle and in each transfer cycle, the stable data transmission band can be secured.
