  • Patent number: 8649425
    Abstract: Disclosed are an apparatus and method for adjusting a bit rate in a security device connected to an external storage, which can determine an output bit rate optimum to the external storage in the security device for receiving a video signal shot by a plurality of cameras and writing the same on the external storage, such as a USB memory, and can vary and adjust the data input bit rate of the video signal shot properly by the plurality of cameras based on the output bit rate. The data input bit rate of a video signal inputted into the security device is higher than the data input bit rate of a video signal outputted to the external storage, thus preventing a failure of not being able to write a video signal shot by a plurality of cameras on the external storage.

  • Patent number: 8208022
    Abstract: An apparatus and a method for removing blooming of a camera image are provided. When a lane marking is not normally detected from an image obtained by photographing a front view or a rear view of a car, it is determined whether the blooming is generated in the image. When it is determined that the blooming is generated, a mask for removing the blooming is generated and superposed on the image. Accordingly, a situation that the lane marking is not normally detected due to the blooming caused by a head light of a car can be reduced or prevented in advance.

  • Patent number: 8199234
    Abstract: An apparatus and method for correcting the backlight of a camera are disclosed. When the camera for photographing a moving image by a photographing device, such as a general-purpose CCD or a general-purpose CMOS, enters into a backlight shooting state for simultaneously photographing an object with a very high luminance level and an object with a very low luminance level, as the shutter speed of the photographing device is varied to a long shutter speed and a short shutter speed, an image shot with the long shutter speed and an image shot with the short shutter speed are synthesized and outputted, thereby enabling a proper luminance level object photographing operation for each of the objects. Accordingly, it is possible to efficiently prevent the phenomenon that the object with the low luminance level looks dark due to the object with the high luminance level.

  • Patent number: 8154642
    Abstract: An apparatus and method for controlling an image sensor output are discussed. When a certain number of valid pixels of an image sensor, such as a CCD, is selected, a corresponding timing parameter is calculated. Signal values output from charge wells respectively corresponding to unit cells of the image sensor are separated or merged and then output by using the calculated timing parameter. Therefore, an image of a user-defined number of valid pixels can be varied and output in various ways, and all electric charges that are photoelectrically converted by the maximum number of valid pixels of the image sensor can be efficiently used.

  • Publication number: 20090225195
    Abstract: A method and an apparatus for processing images in a camera are provided. Even lines and odd lines of a photographing device are respectively read at different points of time to obtain even line data and odd line data and motion estimation is performed on one of the even line data and the odd line data on the basis of an image related to the other of the even line data and the odd line data right of an immediately prior point in time to the one of the even line data and the odd line data to generate a motion-compensated image. Accordingly, a quantity of electric charges charged in the photographing device comes to be increased such that a bright image of an object can be taken and a motion of an image comes to be accurately estimated such that a more distinct moving image can be obtained.
