Abstract: To provide a control device capable of suppressing a shock generated in a vehicle power transmission device in which a first power transmission path and a second power transmission path are provided in parallel, in a transitional period in which the second power transmission path is switched to the first power transmission path during driving.SOLUTION: When switching a power transmission path PT from a second power transmission path PT2 to a first power transmission path PT1 during traveling, the power transmission path PT can be quickly switched to the first power transmission path PT1 by increasing an engine torque Te. Further, since an increase of the engine torque Te ends at timing when an engine rotation speed Ne is determined to be increased to a synchronous rotation speed Nes by the engine torque Te which is an actual torque, a shock that is generated by transmission of the engine torque Te which is generated when the engine rotation speed Ne reaches the synchronous rotation speed Nes, through a mode switching clutch SOWC to the drive wheel 14 side, can be suppressed.SELECTED DRAWING: Figure 8

Abstract: To make it possible to pick up a "miniature picturization" image with a digital camera and obtain an obvious effect.SOLUTION: Upon turn-on the power, a system control unit 29 reads out the details of settings and determines which of "user setting" and "automatic setting" is set during "miniature picturization" processing. When the "user setting" is set, the system control unit performs blur processing in a set blur area and performs monitoring, and makes a transition to a setting screen in response to a request to change the blur area and performs monitoring in the changed blur area. The system control unit then checks a subject detection mode, detects a face from within an angle of view in a face detection mode and performs focus processing, and when the face moves into the blur area, stops the detection. When the "automatic setting" is set, the system control unit sets an AF area subjected to AF processing in a first release to the center of an area of interest and a periphery thereof to the blur area, and performs monitoring. Upon second release depression, after monitoring processing, with shutter control, a main image is transferred from a CCD/CMOS unit 20 to an image processing unit 25 and developed in a memory unit 26, and blur processing is performed on an area other than a focused subject to obtain an effect.SELECTED DRAWING: Figure 1
