Abstract: An image pickup apparatus which is capable of identifying a criminal e.g. when the image pickup apparatus has been broken, without additionally providing a dedicated sensor for detecting an abnormality. A panhead unit supports a camera unit and rotates the same. A rotary encoder detects a rotating state of the panhead unit. A motor control circuit controls the rotating state of the panhead unit based on the rotating state detected by the rotary encoder. A system control circuit stores an image periodically picked up by the camera unit in the controlled rotating state of the panhead unit in a buffer memory. When the rotating state of the panhead unit is not being controlled based on the rotating state detected by the rotary encoder, a memory control circuit reads out images picked up, respectively, before and after a detection time at which the rotary encoder detected the rotating state, and stores the images in an auxiliary memory.

Abstract: A video signal pre-coded using hierarchical coding is transmitted over a communication network, the signal being constituted by data distributed into several hierarchical levels. More specifically, a bandwidth of the communication network is periodically estimated over evaluation periods. A set of hierarchical levels is selected for a current evaluation period, where a transmission rate of the data of the selected hierarchical levels is compatible with the bandwidth estimated for a current evaluation period. A change tendency of the bandwidth is estimated for a following evaluation period. Additional data of the video signal to transmit is then determined depending on the estimated change tendency of the bandwidth, and the data of the selected hierarchical levels and the determined additional data is transmitted during the current evaluation period.

Abstract: A component presence/absence judging apparatus judges the presence/absence of a component through a registration step and an inspection step. The registration step comprises an ante-mounting color information acquisition step, a post-mounting color information acquisition step and an inspection area determination step. Ante-mounting color information is acquired from an ante-mounting image taken at a predetermined portion on an ante-mounting board. Post-mounting color information is acquired from a post-mounting image taken at the predetermined portion on a post-mounting board. Then, a section having a large difference between both color information of the ante-mounting image and the post-mounting image is identified and is determined as an inspection area. At the inspection step, the presence/absence of the component at a predetermined place on each inspection board to be inspected is judged in dependence on the color information on the determined inspection area.

Abstract: A more efficient way of addressing different bit-depths, or different bit-depths and chroma sampling format requirements is achieved by using a low bit-depth and/or low-chroma resolution representation for providing a respective base layer data stream representing this low bit-depth and/or low-chroma resolution representation as well as for providing a higher bit-depth and/or higher chroma resolution representation so that a respective prediction residual may be encoded in order to obtain a higher bit-depth and/or higher chroma resolution representation. By this measure, an encoder is enabled to store a base-quality representation of a picture or a video sequence, which can be decoded by any legacy decoder or video decoder, together with an enhancement signal for higher bit-depth and/or reduced chroma sub-sampling, which may be ignored by legacy decoders or video decoders.

Abstract: A method and apparatus for improved intra chroma prediction mode coding are disclosed. Intra prediction exploits the spatial correlation within a picture or within a picture region. In practice, a picture is divided into blocks and the intra mode prediction is performed on a block basis. In newer coding systems, multiple intra coding modes such as Vertical mode, Horizontal mode, DC mode and Diagonal mode, have been used to improve the coding efficiency of intra coding. Furthermore, a Luma_mode has also been used in intra prediction of chroma component to further improve the performance in the High Efficiency Video Coding (HEVC) standard being developed. However, the mode selection information for intra prediction has to be conveyed to the decoder for proper operation. Spatial features in a picture often exist in both luma and chroma components. The intra luma prediction mode and intra chroma prediction mode will have high probability to be the same.

Abstract: The present invention can suppress the generated code quantity for each image increment so as not to exceeding the target code quantity without having a usage quantizing factor deviate greatly in a sure manner. An image encoding device (200) determines a basic quantization parameter (QPMB) serving as a basic quantizing factor to be predicted in the case that the main encoding generated code comes near the target code quantity at the time of encoding an input image (91). The image encoding device (200) encodes the input image (91) for each feedback control increment by executing quantization using an adapted quantization parameter (QPt) based on an average quantization parameter BaseQP serving as a usage quantizing factor determined based on at least the basic quantization parameter (QPMB).

Abstract: This disclosure describes techniques for region-of-interest (ROI) encoding. In accordance with the techniques described herein, an encoding device may determine a temporal spatial dependency value for a candidate reference video block for inter-coding a current block in a video frame. The encoding device may compare the temporal spatial dependency value to a threshold value and select a coding mode for the current block based on the comparison. A decoding device may receive data defining a ROI as well as the temporal spatial dependency value and decode a video block in the ROI based at least in part on the temporal spatial dependency value. In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.
