PROBLEM TO BE SOLVED: To provide an image processing apparatus and a method for implementing picture-in-picture with frame rate conversion. SOLUTION: The image processing apparatus includes an input buffer unit, a data synchronizing unit, first through third memories, and a memory control unit. The input buffer unit buffers input data which are externally and asynchronously input through two or more channels by different input clock signals and outputs buffered data as first data and first data enabling signals. The data synchronizing unit synchronizes the first data output from the input buffer unit with an output clock signal in response to the input clock signals and the first data enabling signals and outputs synchronized data as second data and second data enabling signals in response to each of the first data enabling signals. The first memory multiplexes the second data according to time sharing, stores the second data in different regions, and outputs stored data in response to a first memory enabling signal. |
