Embodiment Construction

[0050] An exemplary image processing apparatus according to the present disclosure will be explained with reference to preferred embodiments shown in the drawings.

[0051] figure 1 is a block diagram showing the structure of a first exemplary image processing device according to the present disclosure. The exemplary image processing device 10 receives 10-bit input pixel data of pixels making up a plurality of frames at a 60 Hz / 50 Hz input frame rate. The exemplary apparatus 10 performs a dual-rate conversion process and outputs 10-bit output pixel data of pixels constituting a plurality of output frames at a 120Hz / 100Hz output frame rate. The exemplary image processing device 10 includes a memory control circuit 12 , an image processing circuit 14 , and an output circuit 16 .

[0052] The input frame rate is not limited to 60Hz / 50Hz, and the output frame rate is not limited to 120Hz / 100Hz. Frame rate conversion is not limited to 2x upconversion. The number of bits of inp...

Abstract

An image processing apparatus includes a memory control circuit that stores pixel data in a frame memory, an image processing circuit that processes the pixel data stored in the frame memory, and an output circuit that outputs processed pixel data. The memory control circuit divides the pixel data into upper bit portions and lower bit portions, and a lower bit processing circuit stores the lower bit portions in the frame memory by one of (i) dividing lower bit portion of each of the pixel data into n unit portions and storing corresponding one of n unit portions in the frame memory during each of n successive frame periods, and (ii) dividing pixels constituting each of the frames into n groups and storing the lower bit portions of the pixel data of pixels in corresponding one of n groups in the frame memory during each of n successive frame periods.

Description

technical field [0001] This publication relates to an image processing device that performs frame rate conversion processing such as dual rate conversion processing by using pixel data or image data stored in a frame memory. Specifically, this disclosure relates to an image processing device that compresses pixel data or image data before storing the pixel data or image data in a frame memory. Background technique [0002] An image processing device such as a television using a liquid crystal display receives multiple types of pixel data, such as pixel data for each frame or field of a standard television image and pixels for each frame corresponding to each film frame of a film source image data. The image processing device detects the type of input pixel data and performs conversion processing according to the detected type and generates output pixel data for displaying an image. [0003] Recently, an image display device performing frame rate conversion such as the devi...
