摘要： RGB image data outputted from an ADC (3) is processed in an SPU (42) and an RPU (43) and then buffered into a memory (48) as YUV image data. The YUV image data is outputted from a YUV output unit (45), encoded by an image compression and expansion chip (5A) and transmitted to a main chip (4) by a DMAC (52). On the other hand, compressed moving image data stored in the memory (48) is transmitted to the image compression and expansion chip (5A) through the control by a DMAC (44), decoded therein, then converted into RGB image data in an RGB sampling unit (54) and inputted to the main chip (4) by the SPU (42) through a data line (14). With such a construction, it is possible to provide a circuit for compression and expansion, which allows connection with a main processing chip having no YUV input circuit without increasing circuit scale, maintaining general versatility of those circuits.

摘要： While a semiconductor memory operates in a first operation mode with high security, an encrypted command is inputted and then decoded to acquire the first address information. After the semiconductor memory comes into a second operation mode where the level of security is lower than that of the first operation mode, a command is inputted. Then, the second address information is acquired from the command. A control circuit in the semiconductor memory generates an address of 10 bits by using the first address information as a high-order 4 bits and the second address information as a low-order 6 bits and outputs the address to a memory array. With this operation, it becomes possible to read/write data from/to the memory array.

摘要： A transcoder calculates a reference conversion factor on the basis of a ratio between a total target bit rate of a whole second stream and an total input bit rate of a whole first stream and calculates a coefficient of variation from the total target bit rate of the whole second stream and an average output bit rate of a converted second stream in the N period. Next, a quantization step conversion factor in the next (N+1) period is calculated by adding the coefficient of variation to the reference conversion factor. Then, a quantization step value of a second stream in the (N+1) period is calculated by multiplying a quantization step value of a first stream in the (N+1) period by the quantization step conversion factor.

摘要： The single-lens reflex digital camera includes a CCD for imaging an image for storage and a CCD for imaging an image for live view. A pixel signal output from the CCD is processed in an image preprocessing unit, an image general processing unit, and a JPEG processing unit and stored in a memory card as JPEG data. A pixel signal output from the CCD is processed in a live image processing unit and stored in the memory card as YUV data for display. A display control unit reads the YUV data for display from the main memory and outputs the data to a LCD. The CPU adjusts frame rate of the live view image depending on the usage rate of the band of a main bus.

摘要： An image processor includes an encoder and a decoder. The encoder includes a frequency transform unit, a pre-filter, and a color conversion unit that converts a pixel signal of a first color space inputted from outside into a pixel signal of a second color space including a luminance signal and chrominance signals. The decoder includes a frequency inverse transform unit, a post-filter, and a color inverse conversion unit that inversely converts a pixel signal of the second color space into a pixel signal of the first color space. The pre-filter performs prefiltering on one or plural specific signals among the luminance and chrominance signals. The post-filter does not perform postfiltering on the above specific signals.

摘要： The first array register stores neighboring pixels of the same color as the pixel of interest, which are sorted according to the size of the pixel value. The maximum signal comparison circuit compares the value obtained by adding the threshold ThB to the pixel value maxC, which is the (b1)th largest pixel value of the pixels in the first array register and the pixel value P22 of the pixel of interest. When the comparison shows that the pixel value of the pixel of interest P22 is larger, the pixel of interest P22 is determined to be noise, and the pixel value of the pixel of interest is replaced by maxC. The limit signal comparison circuit compares the pixel value P22 of the pixel of interest and the signal upper limit LB. When the comparison shows that P22 is larger than LB and is equal to or larger than maxC, only the pixel of interest is determined to be totally overexposed, and the pixel value of the pixel of interest is replaced by maxC.

摘要： Contour extraction circuits extract contour components YE, CbE, and CrE, respectively, from luminance signal Y, and color-difference signals Cb and Cr, respectively. The two contour components CbE and CrE of the color difference signals are inputted to the LUTs respectively, via the selectors respectively, and converted into the adjustment signals K1 and K2, respectively. The multiplier multiplies the contour component YE by the adjustment signal K1 so as to generate the modulated contour component E1. The multiplier multiplies the modulated contour component E1 by the adjustment signal K2 so as to generate the modulated contour component E2. The adder adds the modulated contour component E2 to the luminance signal Y so as to generate the luminance signal Ya, which has been contour-enhanced based on the contour component of the luminance signal and the contour components of the color-difference signals.

摘要： In a transcoder, a decoder decodes a stream and an encoder encodes the stream again. The encoder calculates the quantization step value by using an average period bit rate (ASn(M)) of a first stream or an average period bit rate (ACn(M)) of a second stream. Buffers store bit rates (Sn, Cn) of the first and second streams for M periods, respectively. The encoder uses the average period bit rate (ASn(M)) of the first stream or then average period bit rate (ACn(M)) of the second stream in any one of the periods M1, M2 and M3 among M periods.

摘要： A correlation judgment part judges a correlation direction on each pixel. In a case where a correlation direction of a specified pixel is a vertical direction and the correlation thereof is small in any other direction, it is judged that the specified pixel is a pixel on an edge in the vertical direction. Then, a noise removal filtering operation is performed on the specified pixel by using pixels on a line in the vertical direction and an edge enhancement operation is performed by using pixels on a line in a horizontal direction.
