摘要： An image processing circuit for eliminating noise from an image without lowering the actual resolution. The image contains input pixels, which include a processing subject pixel and proximal pixels located proximal to the processing subject pixel. Each input pixel has a pixel value. The image processing circuit includes a spatial filter for generating a filter value for the subject processing pixel based on the pixel values of the input pixels and first filter coefficients. A correction circuit compares the filter value with first and second limit values and corrects the filter value based on the comparison to generate a corrected filter value in a range between the first and second limit values. The image processing circuit eliminates noise from the image by correcting the pixel value of the processing subject pixel based on the corrected filter value.

摘要： An image data encoding apparatus performs a two-step process to expand and compress digital image data. The apparatus includes a transform unit for performing orthogonal transform of the image data in a block-by-block manner and generating transform coefficient data. In the first step of the encoding step, a quantizer quantizes the transform coefficient data using a first quantization coefficient to generate first code data. A coefficient operation unit receives the first code data and computes a second quantization coefficient for determining an optimal compression rate of the image data. In the second step of the encoding process, the quantizer receives the second quantization coefficient and quantizes the transform coefficient data to generate second code data. The transform coefficient data is stored in a memory. By optimally compressing the image data, a high image data compression rate is achieved, which allows a greater number of compressed images to be stored. Also, by pipelining the encoding and decoding processes, image processing time is decreased.
