The invention discloses a hybrid image compressing method based on block classification. In the invention, blocks are divided into text/ image block, natural image block and hybrid block according to different features of text/image area and natural image area of original images in the aspect of color and texture; then a compression mode in which palette coding, Hextile coding and LZW coding are combined is used in the text/ image block, a JPEG lossy compression mode is used in the natural image while the algorithm of the combination of the two modes is used in the hybrid block. The invention has the advantages that based on the block classification method, the text/image area and the natural image area can be divided up accurately, and that the blocks are respectively encoded can keep rather acuminate edge of the text/image block so as to enhance visual effect on the basis of ensuring higher compression efficiency and upgrade the peak signal to noise ratio of reconstructed images; the complexity of the algorithm is lower.

An imaging environment that greatly affects image recognition accuracy is recognized for applications in onboard systems of various sorts including imaging devices. An imaging device for imaging areas around the vehicle is mounted on a vehicle. Before executing image recognition processing, information is acquired on objects and texture, such as traffic signs and pedestrian crossings, present within a field of view of the imaging device. An object or texture present within the field of view is then recognized by an image recognition section. Degrees of distortion and defocus of a shape or texture of the object recognized are calculated based on the shape or texture of the object recognized and information previously acquired on the objects or texture. Imaging environment, such as water droplets or dirt on a lens, and whether fog occurs or not, is then recognized based on the degrees of distortion and defocus calculated from the shape or texture of the object recognized.

The embodiment of the invention provides an image processing method and a terminal device, which relate to the technical field of communication, so as to solve the problem that the existing method ofadding a filter only processes the whole image and affects the processing effect of a local image region, wherein the image processing method includes receiving a first input of a user to a target sub-region in N sub-regions of the target image; performing image processing of the target type selected by the first input on the target sub-region in response to the first input, where N is a positiveinteger. The image processing method in the embodiment of the invention is applied to a terminal device.

A method and apparatus for processing images, and an image display apparatus are provided that can produce favorable images even when digitized image are partially magnified (enlarged) or reduced (shrunk). The apparatus for expanding or reducing input image data supplied thereto, for each area of the image data, comprises a high frequency (HF) component smoothing processor that generates smoothed-HF-component image data by smoothing HF components of the input image data; a partial magnification/reduction controller that generates partial magnification/reduction control information that designates positions of pixels in image data obtained after expanding or reducing the input image data for each image area; and a pixel data generator that generates pixel data of pixel positions designated by the partial magnification/reduction control information in the smoothed-HF-component image data, by using pixel data in a neighborhood of the designated pixel positions.

An object of the present invention is to provide a flexographic printing plate having excellent ink transferability in a solid portion and the like and having good printing quality in a halftone portion. The flexographic printing plate of the present invention is a flexographic printing plate having a relief layer including a non-image area and an image area, in which the image area has a halftone dot portion having a halftone dot area ratio of more than 0% and less than 100%, and a solid portion having a halftone dot area ratio of 100%, small dots in the halftone dot portion and the solid portion or small dots in the halftone dot portion have two or more recessed portions having different depths according to a halftone dot area ratio, and the two or more recessed portions having different depths are recessed portions whose depth becomes deeper as the halftone dot area ratio increases.
