Image pickup apparatus and reproduction control apparatus
First Claim
1. An image pickup apparatus comprising:
- image pickup means which is capable of picking up an image at a first frame rate and a second frame rate that is higher than the first frame rate;
detection means for detecting a highlight scene;
control means for switching over a frame rate of the image pickup means in response to detection of the highlight scene by the detection means;
lens driving means for performing a zooming operation on a lens; and
sensor means for detecting an angular velocity when the image pickup apparatus moves,in which the detection means detects the highlight scene only when (i) a first determination indicates that the lens driving means is not performing the zooming operation, (ii) a second determination indicates that the angular velocity detected by the sensor means does not exceed a preset threshold value, and (iii) a third determination indicates that a movement of a subject calculated by performing an inter-frame difference calculation exceeds a predetermined value.

Abstract
Image pickup means is capable of picking up an image at a first frame rate and a second frame rate that is higher than the first frame rate. A highlight scene is detected by detection means. When detecting the highlight scene, image pickup operation is performed at a high speed mode and an image signal at high frame rate (240 fps) is produced for a period of predetermined time. When detecting no highlight scene, image pickup operation is performed at a normal mode and an image signal at normal frame rate (60 fps) is produced. It is possible to save time and labor for performing a switchover operation of a frame rate when imaging a highlight scene. It is also possible to save power consumption and a capacity of a storage medium.
