摘要： In a high speed image capturing state, a camera signal processing circuit is not needed to perform a signal process at a high screen rate, but at a regular screen rate. In the high speed image capturing mode, raw data of 240 fps received from an image sensor 101 are recorded on a recording device 111 through a conversion processing section 201 and a recording device controlling circuit 210. Raw data that have been decimated and size-converted are supplied to a camera signal processing circuit 203 through a pre-processing circuit 202 and an image being captured is displayed on a display section 112 with a signal for which a camera process has been performed. In a reproducing state, raw data are read from the recording device 111 at a low screen rate according to a display performance of the display section 112 and the raw data that have been read are processed are processed by the pre-processing circuit 202 and the camera signal processing circuit 203 and a reproduced image is displayed by the display section 112.

摘要： A first video signal having a first frame rate optionally settable is generated by an image pickup device, and the first video signal is memorized in a memory and outputted from the memory. A write control device controls the write of the first video signal with respect to the memory, and a read control device controls the read of the video signal with respect to the memory. The write control device writes respective first frame data constituting the first video signal in the memory in each cycle determined by the first frame rate of the first video signal. The read control device reads the first frame data as a second video signal. The second video signal is formed from sequentially arranging the first frame data in a partially duplicating manner in a standard video signal having a standard frame rate based on a determined arrangement rule. The predetermined arrangement rule is an arrangement rule employed when respective frame data constituting a video signal having a second frame rate equal to or lower than the standard frame rate are arranged in a duplicating manner in the standard video signal. In the foregoing manner, an time elongation/contraction effect on an image can be speedily and inexpensively obtained.

摘要： Dynamic video capture rate control techniques are described. In one or more implementations, a method is described of dynamically controlling video capture rate. Capture of video of a camera is caused by a device to occur at a first rate for a first collection of images in the video. During the causation of the capture of the video at the first rate, an input is detected by the device to change to a second rate that is different than the first rate. Responsive to the detection of the input, the capture rate is changed from the first rate to the second rate, the capture of the video by the camera is caused to occur at the second rate for a second collection of images of the video, and timestamps of the first collection of images or the second collection of images are transformed to configure the image in the video for output at a substantially uniform rate relative to each other.

摘要： In an embodiment of a method for converting an input video sequence, comprising digital images organized in frames and operating at a variable frame-rate, into an output video sequence, operating at a pre-set constant frame-rate, it is envisaged to store the input video sequence temporarily and to control fetching of images of said temporarily stored input video sequence.The method moreover envisages: controlling fetching of images from the temporarily stored input video sequence by adjusting an emptying rate to form an intermediate video sequence; and carrying out an operation of motion-compensated interpolation on the intermediate video sequence to form the output video sequence operating at a pre-set constant frame-rate, the emptying rate being adjusted as a function of a number of images of the input video sequence with variable frame-rate temporarily stored. An application is in the reproduction of video sequences in mobile terminals, with the capacity of audio-video conversation, for example for videoconferences.

摘要： An image signal generator generates an imaging signal having a frame rate that is controlled to be variable. A frame rate converter generates a monitor image signal. Upon receiving communication information from an external source, a controller controls the operations of the image signal generator and the frame rate converter on the basis of the communication information. When an instruction to specify the frame rate of the monitor image signal is given from a user interface, the controller controls the frame rate converter to generate a monitor image signal having a specified frame rate by giving priority to this instruction over the communication information.
