  • Publication number: 20120114035
    Abstract: The minimum Sum of Absolute Differences obtained by a motion vector search roughly judges the magnitude of quantization error by whether or not exceeding a predetermined threshold value. When the quantization error is lower, whether or not visually noticeable noise exists in some of the pixels of the current macroblock is judged based on the amount of flatness and noise detected in each of the 4×4 pixel blocks of the current macroblock partitioned into 16 sub-macroblocks. If there is visually noticeable noise, intra-frame coding is selected. When the quantization error is higher, whether or not visually noticeable noise exists in the current macroblock is judged while considering the magnitude of the motion vector. If there is visually noticeable noise, intra-frame coding is selected.

  • Patent number: 8169512
    Abstract: A digital still camera includes an amplification circuit, a timing generator, sample hold circuits, a differential amplifier, an analog/digital conversion circuit and a control unit. The generator generates a first-pulse signal and a second-pulse signal at different timings. The circuits sample analog video signals outputted from the amplification circuit at timings when the first-pulse signal and second-pulse signal, respectively, are provided and hold levels of the analog video signals. The amplifier acquires a difference between the levels of the analog video signals. The circuit obtains a digital video signal corresponding to the analog video signal on the basis of the difference. The unit changes the timings to provide the first- and second-pulse signals to the first- and second-sample hold circuits, respectively, and a bias current depending on the driving period.

    Abstract: In a digital camera 1, when a shutter button is pressed halfway, then a photographic scene is evaluated until the shutter button is fully depressed, and based on automatic parameters corresponding to the evaluated photographic scene which are set, each portion is controlled in accordance with the set automatic parameters (Step S3). Furthermore, tags for manual setting corresponding to the photographic scene evaluated in Step S2 are superimposed on a live view image (Step S5). Whether a touch for any of the tags has been detected is determined (Step S9). If a touch has been detected, manual parameters corresponding to the touched tag in the automatic parameters stored in RAM in Step S3 are changed by one level and updated (Step S13). If the shutter key has been operated, still image photographic processing is performed with the parameters updated and stored in RAM in Step S13 (Step S23).
