摘要： A CODEC compresses and encodes a motion picture captured at a high speed of 240 fps frame rate in MPEG format. The CODEC divides pictures in each frame into I pictures and the main frame P pictures and the other sub frame P pictures. In encoding P pictures of the main frame, the CODEC uses I pictures that are adjacent on the time axis or P pictures of other main frames as a reference picture. With a playback device, etc., of its motion picture playback performance of 60 fps, to perform an actual speed playback with the playback time being equal to the picture-capturing time, only the main frame alone is to be subjected to playback, in that case the decoding process of P pictures of the sub frames is not required.

摘要： 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 4x4 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.

摘要： An image capture device sets a central vicinity of a frame of a predetermined area as a focus region upon detecting a half-press operation of a shutter button in a through-the-lens image displaying, designates a central vicinity pixel region of the region as a pixel region to be tracked, and determines whether or not the designated pixel region is adequate as an object of tracking. If the pixel region is adequate, the pixel region is tracked until the shutter button is detected as pressed down fully. When a fully-press operation of the shutter button is detected, the frame of a predetermined area is displayed in a fixed manner on a display unit. Upon a detection that a change of the pixel region has occurred, or the pixel region has contacted or exceeded the frame of a predetermined area, a recording processing is started immediately by a high speed consecutive capture.

摘要： In a digital camera 1, a storing means stores feature quantities of a subject area in an image, and a search point setting means sets a plurality of search points in the subject area. Next, an updating means updates coordinates of the set plurality of search points using random numbers. Then, a weight setting means compares feature quantities of the updated search points with the stored feature quantities, and sets a weight for each search point based on similarity. Next, a sorting means sorts the search points depend on those weight, and a variance acquiring means calculates the variance of the sorted search points. Then, an angle-of-view adjusting means determines the amount of adjustment for the angle-of-view based on the calculated variance.
