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： 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： A data processing apparatus includes a central control section, an image analysis section, a RAM (Random Access Memory), an external memory section and a user operation input section. The central control section is connected to the image analysis section, the RAM and the external memory section via a bus. Based on image data prepared by an image input section, the image analysis section performs a process of specifying where on the display screen of a display section a portion specified by the image input section lies.

摘要： A control unit monitors a state of captured image sequentially outputted by an image capturing unit. The control unit carries out a first determination that determines whether or not the state of a captured image satisfies a prescribed condition. When the result is that the prescribed condition is satisfied, the captured image is recorded in a recording unit. The control unit also carries out a second determination that determines whether or not the state of the captured image is appropriate for being subjected to the first determination. When the result is that the state is not appropriate for being subjected to the first determination, a warning is issued to the user to this effect.
