摘要： In a digital camera, when snapshot shooting is instructed during recording of a moving image, a shot still image is temporarily pushed aside in a memory area for use in pushing aside (7a) in a frame buffer (7). A currently shooting motion image and a still image are displayed in parallel on a display (9), so that a user can confirm a content of a snapshot. The moving image continues to be recorded even during a push-aside operation. After a moving image processing is completed, the still image is processed by an image correcting circuit (4). The frame buffer (7) comprises a plurality of frame recording areas, and is shared on the occasions of a moving image processing and a still image processing. In a normal moving image processing, these areas are utilized in a cyclic manner, and when the still image is shot, any of areas will be utilized. Thereafter, the rest of areas are utilized in the cyclic manner for the moving images. The recording function for the moving image and still image is improved at low cost, it becomes easy to take a snapshot, and the merchandise size is not increased.

摘要： Structure information on picture within a GOP of a coded data sequence is acquired beforehand. At the time of high-speed reproduction, a high-speed reproduction mode judging unit judges by referring to the picture structure information whether a high-speed smooth reproduction is possible or not. If the high-speed reproduction is possible, a high-speed smooth reproduction control unit performs the high-speed smooth reproduction. If not possible, a high-speed skip reproduction control unit performs high-speed skip reproduction. For reverse reproduction, image data for one GPO, for example, are recoded by an MPEG encoder and then the recoded image data are stored in a storage. Then, a coded data amount predicted from the structure information on the picture within the GOP is compared with the capacity of the storage, and a countermeasure such as raising a compression ratio is taken if the estimated coded data amount exceeds the capacity of the storage.

摘要： An encoding apparatus 100 performs intra-frame encoding or inter-frame encoding using a predetermined scheme, or performs an orthogonal transform on an image as one process in the intra-frame encoding or the inter-frame encoding. In order to perform the intra-frame encoding, the inter-frame encoding, or the orthogonal transform, various parameters to be specified by the encoding apparatus are specified as an abbreviated parameter which uses a number of bits less than the number of bits that is assigned by the specification. This enables to reduce the data amount of a parameter in the coded data.

摘要： A monitoring unit monitors continuously wavelet transform component output from a wavelet transformer. When a condition “make all the components of the HH sub-band 0” is applied as a quantization strategy, the monitoring unit detects the maximum value N among the components in the HH sub-band and determines the threshold as N+1. The threshold is then sent to a quantizer.

摘要： An image coding apparatus is provided which satisfies various levels of demands on image distribution, both from image providers and from users. The image coding apparatus includes a coding block which codes predetermined image data. A separation unit separates the coded image data into basic data for reproducing contents of the coded image data as a visible image, and complementary data for complementing the basic data, so that the two pieces of data are distributed on different occasions. An adding unit adds information for independent copyright control to at least either one of the basic data and the complementary data.

摘要： A region of interest is set within an image, the region of interest is tracked along motion of an object marked out within the image, and coding is performed in a manner that image quality differs between the region of interest and a region other than the region of interest. A wavelet transform unit applies a low-pass filter and a high-pass filter in the respective x and y directions of an original image, and divides the image into four frequency sub-bands so as to carry out a wavelet transform. A quantization unit quantizes, with a predetermined quantizing width, the wavelet transform coefficients outputted from the wavelet transform unit. A motion detector detects the motion of an object. A ROI setting unit moves a ROI region according to this motion of an object. In the case of moving images where a viewpoint changes, the background may be separated from the object and then the ROI region may be moved according to the motion of the object and the motion of the background.
