摘要： An ROI in a first image and a second image are synthesized by synthesizing first wavelet coefficient data corresponding to the first image and second wavelet coefficient data corresponding to the second image. An ROI coefficient and a non-ROI coefficient in the first wavelet coefficient data are determined on the basis of a mask for the first wavelet coefficient data, and the ROI coefficient and a wavelet coefficient in the second wavelet coefficient data, which is corresponding to the non-ROI coefficient, are synthesized. When the above coefficient synthesis is performed after a decomposition level of the first wavelet coefficient data is increased, the first wavelet coefficient data is adjusted on the basis of auxiliary wavelet coefficient data corresponding to an auxiliary image which can be equated with the first image before increasing the decomposition level.

摘要： An ROI coefficient and a non-ROI coefficient in first wavelet coefficient data corresponding to a first target image are determined on the basis of mask data which is developed for the first wavelet coefficient data. The ROI coefficient in the first wavelet coefficient data and a coefficient in second wavelet coefficient data corresponding to a second target image are synthesized. Synthesized coefficient data are thereby generated. Inverse wavelet transformation is performed on the synthesized coefficient data until a decomposition level becomes a predetermined end level. Synthetic image data are thereby generated.

摘要： A very long instruction word (VLIW) processor that performs efficient processing including extended bits operations is provided. The VLIW processor includes an instruction control unit, a register file unit, and an instruction execution unit. The instruction execution unit includes a plurality of slots, and a state register arranged between the second slot and the third slot to transfer N-bit data between the second and third slots. The VLIW processor stores data output from the third slot into the state register and uses the data, and thus achieves efficient processing including bit-expanded operations, such as processing performed in response to instructions commonly used in image processing, image recognition, and other processing, while preventing scaling up of the circuit.

摘要： A WT unit performs wavelet transformation on original image data to generate first image data. An ROI developing unit, based on ROI information, specifies an ROI corresponding portion corresponding to an ROI and a non-ROI corresponding portion corresponding to a non-ROI to the first image data. A high-frequency cutting unit performs, on the first image data, a high-frequency cutting process that cuts a high-frequency component of the non-ROI corresponding portion. A low-frequency blurring unit performs, on the first image data, a low-frequency blurring process that blurs a low-frequency component of the non-ROI corresponding portion. The IWT unit performs inverse wavelet transformation on second image data (first image data obtained after the high-frequency cutting process and the low-frequency blurring process are performed) to generate third image data.

摘要： Circuitry configured to generate an ROI mask by determining whether each of quantized wavelet coefficients constituting quantized image data is associated with an ROI or a non-ROI in an original image on the basis of the scaling amount of the Max-shift method, generate first image data by performing inverse quantization on the quantized image data after being scaled down, generate second image data having a specified decomposition level by performing inverse wavelet transformation on the first image data, generate a restored ROI mask having the same decomposition level as that of the second image data by performing a predetermined process on the ROI mask once or a plurality of times, generate masked image data by applying the restored ROI mask to the second image data, and perform the inverse wavelet transformation on the masked image data until a decomposition level becomes zero.
