Abstract: A digital camera includes an image capturing unit, an angular velocity sensor, an image determination unit, and an image composition unit. The angular velocity sensor acquires a displacement amount in a field of view of image data when the image data is captured at predetermined time intervals.

Also, the image determination unit determines whether or not the image data thus captured is valid as a composition target based on the determination criterion thus set. The image composition unit combines image data determined by the image determination unit as being valid as a composition target.

Abstract: Techniques for generating synchronized dictionaries for sparse coding to facilitate encoding of video content are presented. An encoder can generate a dictionary that can be synchronized with a corresponding dictionary maintained by a decoder. The encoder can use the dictionary to facilitate encoding video content, based on sparse coding, for transmission to the decoder. During a video session, the encoder and decoder can signal each other to identify common dictionaries between the encoder and decoder, wherein desired common dictionaries can be used for coding content. During a session, the decoder can dynamically select visual images that can be used to dynamically add new elements to the corresponding dictionary. The decoder can provide identifying information regarding these visual images to the encoder. The encoder can select corresponding visual images to add to its dictionary to maintain the synchronization of these common dictionaries.

Abstract: A vehicle periphery monitoring apparatus detects the presence of a moving object along a vehicle periphery. The apparatus sets multiple detection lines along a horizontal axis of an image captured by a camera, and detects a brightness change of a pixel along the detection lines. With reference to the brightness change detected along the detection line and a parameter for determining whether such brightness change is caused by the moving object, the apparatus determines the presence of the moving object. In addition, the apparatus changes a determination condition for determining the moving object such that as the number of detection lines along which the brightness change is detected decreases, the harder it is to satisfy the determination condition for determining that the moving object is present.
