摘要： A camera module compresses image data and produces a thumbnail image of this image data in FIFO order (First In First Out) by several lines of the image so as to enable transmission of the image data to the host module while significantly decreasing the size of the frame buffer memory. This can be achieved by, for example, an electronic device, including: a camera module, which transmits the data acquired by photographing; and a host module, which receives the data; wherein the camera module alternately transmits a compressed small portion including the data made by compressing the small portion of the image data for one frame and a sub small portion including the data with the resolution of the small portion reduced.

摘要： On the image compression side, each lossless wavelet transformation coefficient on which a lossless wavelet transformation for an image is effected, is first subjected to quantization and entropy coding in a coarse step size. Thereafter, quantization error signals are successively subjected to quantization and entropy coding in a fine step size to thereby generate a progressive coded bit stream. On the image expansion side, lossless wavelet transformation coefficients obtained by entropy decoding and inverse quantization are subjected to inverse lossless wavelet transformations every coded bit streams bearing respective stages for image progressive reconstruction display. Data obtained by the inverse transformations is added to the already-reconstructed image data together with updated auxiliary information about each image to thereby reconstruct and display the image progressively. Now, the updated auxiliary information necessary to update the image is generated from some of information about lossless wavelet transformation coefficients necessary to update the image quality by one stage and some of lossless wavelet transformation coefficients necessary to generate the already-displayed image, whereby it is not necessary to hold all the information about lossless wavelet transformation coefficients necessary to generate a pre-updating image and memory's capacity can be reduced.
摘要翻译：在图像压缩侧，首先进行对图像进行无损小波变换的每个无损小波变换系数，以粗步长进行量化和熵编码。此后，量化误差信号以精细的步长连续进行量化和熵编码，从而生成逐行编码比特流。在图像扩展侧，通过熵解码和逆量化获得的无损小波变换系数对于具有用于图像逐行重建显示的各个阶段的每个编码比特流进行逆无损小波变换。通过逆变换获得的数据与关于每个图像的更新的辅助信息一起被添加到已重构的图像数据中，从而逐渐地重建和显示图像。现在，从关于将图像质量更新一个阶段所需的无损小波变换系数的一些信息和生成已经显示的图像所必需的一些无损小波变换系数的一些信息生成更新图像所需的更新的辅助信息，由此，不需要保持关于生成预更新图像所必需的无损小波变换系数的所有信息，并且可以减少存储器的容量。

摘要： An information terminal that can perform image processing in consonance with the use state and the use purpose. When a retrial module is started, removal means removes part or all of the interpolation processing performed for a Bayer-type module. Thereafter, data obtained by the removal are transmitted to color interpolation means, another color interpolation process is performed for the data, and the resultant data are transmitted to image quality correction means. The image quality correction means performs another image quality correction process for the data, and transmits the obtained data to JPEG encoding means.
