Problems solved by technology

However, if the image signal recorded in this way is reproduced at the regular field frequency of the video signal, all captured images recorded are reproduced in slow motion
Therefore, there are cases where the waiting time for displaying the desired slow-motion image is long

Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 is a block diagram illustrating the structure of an image capturing device. The image capturing device 10 is configured to be switchable between a standard image capturing mode and a high-speed image capturing mode as operation modes. The standard image capture mode is an operation mode during normal image capture in which an image signal having a preset reference image rate is generated. The high-speed image capture mode is an operation mode in which image capture is performed at a speed higher than that of the standard image capture mode so that slow-motion reproduced images with high temporal resolution can be obtained to generate An image signal at an image rate that is an integral multiple of the reference image rate (hereinafter referred to as "high-speed image rate"). Here, the term reference picture rate refers to the field rate or frame rate used in te...

Abstract

Provided are an image reproducing apparatus, an image reproducing method, an imaging apparatus and a method for controlling the imaging apparatus. At the time of reproducing an image signal of a picked up image generated by imaging at an image rate higher than that previously set, a signal processing section, which converts an image signal into that at the previously set image rate, is supplied with an image signal to be reproduced. The image rate of the image signal to be reproduced is controlled based on reproduction control information generated by using the motion detection results of the picked up image, reproduction speed of the picked up image is reduced as the detected motion becomes large, and an image signal of a slow motion reproduction image is outputted.

Description

technical field [0001] The present invention relates to an image reproducing device, an image reproducing method, an image capturing device and a control method thereof. More specifically, the present invention is intended to perform image capture at an image rate higher than a preset reference image rate so that when an image signal of a generated captured image of the captured image is reproduced at the reference image rate, the The movement of the image to control the reproduction speed. Background technique [0002] Conventionally, in Japanese Unexamined Patent Application Publication No. 2005-295423, a method is proposed in which captured images are temporarily saved in a memory and also recorded on a recording medium so that to reproduce slow-motion video. [0003] That is, in the technique disclosed in Japanese Unexamined Patent Application Publication No. 2005-295423, an image signal with a field frequency of, for example, 240 fields per second is generated, and th...
