摘要： It is an object of the present invention to prevent an image distortion from occurring by using a line memory of small memory capacity. For example, an image is decomposed into strip regions 12, and each strip region 12 is filtered together with certain excess data 14 from a neighboring strip region 12 to prevent an image distortion from occurring at the boundary between the strip regions 12 while executing band decomposition on the strip region 12 which is smaller in size than the entire image with a smaller line memory. In the band decomposition, a line memory which supports band decomposition of, for example, 3 decomposition levels is repeatedly and recursively used, whereby band decomposition of deeper decomposition levels is executed without any problems. In this manner, line-based wavelet transform for deeper decomposition levels is executed with a small line memory. Also reverse wavelet transform is executed in the similar manner.
摘要翻译：本发明的目的是通过使用小存储容量的行存储器来防止图像失真发生。例如，图像被分解为条带区域12，并且每个条带区域12与来自相邻条带区域12的某些多余数据14一起被滤波，以防止在条带区域12之间的边界处发生图像失真，同时执行频带分解在条带区域12上，其尺寸小于具有较小行存储器的整个图像。在频带分解中，重复并递归地使用支持例如3个分解电平的频带分解的行存储器，由此执行较深分解电平的频带分解而没有任何问题。以这种方式，用较小分辨率级别的基于行的小波变换用小的行存储器执行。也以类似的方式执行反向小波变换。

摘要： An image processing apparatus includes a first storage section and a second storage section, a storage control section, and a computation section. The storage control section sequentially acquires block images obtained as a result of dividing an input image, and stores the block image as a target block image in the first storage section, while storing, in the second storage section, image data of, in a region of the target block image, a region abutting un-inputted block images in the input image, as image data of an abuttal region. The computation section implements a resizing process for changing the size of the target block image by performing an interpolation calculation using image data of the target block image stored in the first storage section and the image data of the abuttal region stored in the second storage section.

摘要： An image processing apparatus is provided which offers higher versatility than conventional image processing apparatuses. When an input signal to a spatial filtering block is a monochrome signal that contains Y component only, a selector selects its input terminal and a selector selects its input terminal. Then, a low-pass filter output signal of a programmable spatial filter is inputted to a spatial filter, and a low-pass filter output signal of the spatial filer is inputted to a spatial filter. That is, the programmable spatial filter and the spatial filters are connected in series (in cascade), and the cascade-connected three spatial filters perform filtering operation. In this example, low-pass filters with 5×5 taps are connected in cascade in three stages, which enables low-pass filtering with 13×13 taps.

摘要： In image input devices such as digital still cameras, processing is speeded up and power consumption is reduced by arranging in a RPU (23) performing real time processing of a pixel data from a CCD (21), such that only special exceptional image processing not being prepared previously is subjected to a software program processing in a CPU (24) and, in post processing in which a general image processing is carried out, a pixel data temporarily stored in a main memory (29) is inputted again to the RPU (23) and then processed. This enables to sharply speed up processing, and minimize a prolonged processing in the CPU (24) to reduce power consumption, when compared to the case of executing by software problem processing.

摘要： An image conversion device is provided with a first buffer area for storing either one of even field and odd field of inputted dot sequential data and a second buffer area for storing the other thereof. A data transfer control circuit controls in such a manner that, during a period in which one of the two fields is written in the first buffer area, the other field, stored in the second buffer area, is read out in a color field sequential format, and during a period in which the other field is written in the second buffer area, the other field, stored in the first buffer area, is read out in a color field sequential format. A pixel interpolating circuit carries out an insertion-interpolating process on the field read out from the image storing unit, and outputs the resulting data. Thus, it becomes possible to prevent color breaking at the time of displaying motion images on a color field sequential type display by using a buffer area having a capacity of one frame.

摘要： To enable a brightness histogram operation without requiring a special-purpose integration circuit and memory.An image processing apparatus is provided with a gamma correction processing part. The gamma correction processing part 6 includes a LUT operation circuit 10 having a LUT memory 11 for gamma correction, a simplified gamma correction circuit 12, selectors 14 and 15, and a register 13. When the gamma correction processing part 6 is used exclusively for gamma correction, the CPU 3 makes the register 13 hold aw control signal of L level to thereby cause the selectors 14 and 15 to select “0” terminals. The LUT memory 11 selects and outputs a gamma correction value (LUT conversion value) while referring to input pixel data as address data. On the other hand, when the gamma correction processing part 6 is used for brightness histogram operation, the CPU 3 makes the register 13 hold a control signal of H level to thereby cause the selectors 14 and 15 to select “1” terminals. The LUT memory 11 is used as a memory for storing an accumulation value of the brightness histogram operation.
