  • Patent number: 8515210
    Abstract: An imaging device made of a single-chip type including a RGB Bayer pattern color filter is where pixel signals outputted from the imaging device are inputted through a signal processing part to an image processing part. A correlation judgment part judges a correlation between the pixel signals, and an interpolation processing part performs a pixel interpolation process based on a correlation result. Thus, each pixel signal becomes a perfect signal having all R, G and B color components. Filter factors for a filter are determined based on the correlation result, and a filtering process is performed on the pixel signals subjected to the pixel interpolation.

  • Patent number: 8050506
    Abstract: An image enhancement device is obtained which is capable of extracting, as regions of interest, still objects or objects with smaller motion vectors, or regions located out of the central area of an image. An image processing module (22) applies memorized-color correction to image data, and then stores, in an SDRAM (7) through a memory interface (26), information about the positions of the memorized-color-corrected pixels and information about the application levels (correction levels) applied to the memorized-color-corrected pixels. A mask signal generating module (23) refers to the positional information stored in the SDRAM (7) to extract the memorized-color-corrected regions of the image data as regions of interest.

  • Patent number: 7995868
    Abstract: The present invention relates to an interpolation method and a filtering method which utilize a correlation between pixel signals, and it is an object of the present invention to provide a sharp and high-quality image even if an error occurs in correlation degree judgment. To accomplish the above-mentioned object, an imaging device 10 is of a single-chip type, and includes a RGB Bayer pattern color filter 11, and an image is processed in a manner to be described below. Pixel signals outputted from the imaging device 10 are inputted through a signal processing part 20 to an image processing part 30. A correlation judgment part 31 judges a correlation between the pixel signals, and an interpolation processing part 32 performs a pixel interpolation process based on a correlation result. Thus, each pixel signal becomes a perfect signal having all R, G and B color components.

  • Publication number: 20100268729
    Abstract: A technique for drawing or managing multimedia data by desired groups. In a built-in memory of a cellular phone terminal, thirteen picked-up image data are stored. In tag information of each of the thirteen picked-up image data, information on date and time is recorded when an image of the data is picked up. When a user specifies the range of image pickup date and time, eight picked-up image data that match the specified range of image pickup date and time are selected and synthetic image data is generated from these eight picked-up image data.

  • Patent number: 7787690
    Abstract: RGB image data outputted from an ADC (3) is processed in an SPU (42) and an RPU (43) and then buffered into a memory (48) as YUV image data. The YUV image data is outputted from a YUV output unit (45), encoded by an image compression and expansion chip (5A) and transmitted to a main chip (4) by a DMAC (52). On the other hand, compressed moving image data stored in the memory (48) is transmitted to the image compression and expansion chip (5A) through the control by a DMAC (44), decoded therein, then converted into RGB image data in an RGB sampling unit (54) and inputted to the main chip (4) by the SPU (42) through a data line (14). With such a construction, it is possible to provide a circuit for compression and expansion, which allows connection with a main processing chip having no YUV input circuit without increasing circuit scale, maintaining general versatility of those circuits.

  • Patent number: 7720309
    Abstract: A similar-image detecting part detects similar image regions similar to one another in a plurality of frame images captured by rolling shutter type exposure. A displacement-vector detecting part detects a displacement vector of each of the similar image regions with respect to a reference position in each of the plurality of frame images. An average calculating part calculates an average of displacement vectors in the plurality of frame images. A correcting part shifts a similar image region in one of the plurality of frame images such that the displacement vector of the similar image region becomes the average calculated by the average calculating part.
