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.
摘要翻译：图像转换装置设置有用于存储输入的点序列数据的偶数场和奇数场中的任一个的第一缓冲区域和用于存储另一个的第二缓冲区域。数据传送控制电路以这样的方式进行控制：在两个场中的一个被写入第一缓冲区的时段期间，存储在第二缓冲区中的另一场以彩色字段顺序格式读出，并且在其他字段被写入第二缓冲区域的时段期间，以颜色字段顺序格式读出存储在第一缓冲区域中的另一字段。像素内插电路对从图像存储单元读出的场进行插入插入处理，并输出结果数据。因此，通过使用具有一帧容量的缓冲区，可以防止在色域顺序型显示器上显示运动图像时的色彩破坏。

摘要： The first frame of captured image data is stored as raw data in a main memory, and parameters for exposure control and white balance control are calculated from the stored image data and are set in the RPU. The second and subsequent frames of captured image data are processed in real time in the RPU without being stored in the main memory after being output from a CCD. The second and subsequent frames of captured image data are subjected to exposure control, white balance control, and JPEG compression, and then, are stored in the main memory. After operations for continuously capturing images are finished, the raw data corresponding to the first frame stored in the main memory is read by the RPU, where exposure control and white balance control are performed, and then, is stored as JPEG data in the main memory.

摘要： OSD data YD includes a color designating signal As and a color changing signal Ex. When a color register number is designated by the color designating signal As, a color storage unit 41 outputs an appropriate color signal. A Y signal is branched from the outputted color signal and subjected to a modulating process by the color changing signal Ex. The Y changing signal obtained by the modulating process is merged with a Cb signal and a Cr signal so as to form new color signal. The OSD data YD with changed color is subjected to a synthesizing process with image data XD according to the predetermined mixture ratio.

摘要： The least significant bits of respective count values of an H counter and a V counter are combined, to generate a timing signal defining a 2×2-size repeat block. A timing register including four registers each storing data which determines a color of each location within the repeat block is provided for each of input channels. A selector selects one of outputs of the timing registers based on the timing signal, and generates a signal designating a color of a pixel at a certain time for each of the input channels. A register storing black level correction data for each color is used in common by the input channels. For each of the input channels, an item of black level correction data at the certain time is selected based on the signal designating the color of the pixel at the certain time and input to a pre-processing circuit in each of the input channels.
