  • Imaging apparatus using MJPEG compression method
    Patent number: 11356635
    Abstract: An imaging apparatus includes at least one processor to implement: a re-sizer configured to re-size an image to a predetermined size, an encoder configured to encode the re-sized image, and a frame rate controller configured to calculate an actual bit rate of the encoded image for a preset period of time, compare a user-set target bit rate with the calculated actual bit rate, adjust a frame rate of the encoded image according to a result of the comparison, and output an encoded image signal at a user-set target bit rate irrespective of a complexity of the encoded image.
    Type: Grant
    Filed: May 23, 2016
    Date of Patent: June 7, 2022
    Assignee: Hanwha Techwin Co., Ltd.
    Inventors: Sujit Kumar Mahapatro, Karthikeyan Kannaiyan
  • Quantization parameter determination method and image capture apparatus
    Patent number: 10999577
    Abstract: A method of determining a quantization parameter includes determining an adjustment range of a quantization parameter correction value based on a size of a motion area of an input image, calculating an average bitrate value of the input image, and adjusting the quantization parameter correction value by decreasing the quantization parameter correction value within the adjustment range in response to determining that the average bitrate value is greater than an upper limit value, and by increasing the quantization parameter correction value within the adjustment range in response to determining that the average bitrate value is equal to or less than a lower limit value.
