  • Publication number: 20210217146
    Abstract: An image processing apparatus notifies downstream circuits of the result of anomaly detection without increasing the amount of data involved. The image processing apparatus includes an anomaly detecting section and an output section. The anomaly detecting section detects an anomaly of an image signal from a given pixel. In a case where the anomaly is not detected from the given pixel, the output section outputs a pixel value within a predetermined range. On the other hand, in a case where the anomaly is detected from the given pixel, the output section outputs a pixel value outside the predetermined range. This enables downstream circuits to identify the pixel of which the anomaly is detected by whether or not the pixel value falls within the predetermined range.

  • Patent number: 9030573
    Abstract: A camera system, image processing method and computer program stored on a computer readable medium for image processing. Long and short accumulation images with longer and shorter exposure times are respectively obtained from one field. First and second long accumulation evaluation values are computed from the long accumulation image. A short accumulation evaluation value is computed from the short accumulation image. A short accumulation target exposure time and short accumulation exposure control information are acquired from the short accumulation evaluation value and a first target level. A long accumulation evaluation value is acquired by synthesizing the first and second long accumulation evaluation values. Long accumulation exposure control information is acquired from the long accumulation evaluation value and a second target level. An image is generated from the long accumulation image and the short accumulation image.

  • Patent number: 7529400
    Abstract: A sub-sampling portion (101) sub-samples images of data corresponding to the left and right viewpoints. A joining method selector (104) selects the joining method that minimizes the discontinuity at the boundary in the joined image when the sub-sampled images of data are joined. A joining portion (102) joins the plurality of images data, based on the selected joining method. An encoder (103) encodes the joined image data, and a joining method encoder (105) encodes the information of the joining method. A multiplexer (106) multiplexes these pieces of coded data. In this way, the continuity of the joined image is improved, whereby the coding efficiency is enhanced.

  • Publication number: 20080019445
    Abstract: A bitstream comprising only I and P frames can be reproduced at a high speed without increasing the process amount nor degrading the picture quality. A prediction structure of the P frames of a coded bitstream is modified, and a control unit (112) is used to cause a variable length coding unit (105) to add and code a prediction usage flag indicative of whether the P frames can be referred to from the following frames and a reference image number notified, as information indicative of the frame numbers referred to by the P frames, by a motion detection unit (111). The coded image of a frame, in which the prediction usage flag is set up, is stored in a frame memory (109) and can be referred to during predicting and coding the P frames.
