  • Patent number: 9013597
    Abstract: An image pickup apparatus which is capable of accurately compensating for noise even when images are continuously taken at varying exposures. First and second image signals corresponding to the first and second exposures are output. The first and second image signals are subjected to a noise compensation process and then synthesized together to obtain a composite image signal. Data obtained in the first and second image signals when the noise compensation process was carried out on the first and second image signal is inherited, and a noise compensation process on the next first and second signals is carried out based on the data.

  • Publication number: 20110032382
    Abstract: The method includes setting a first aspect ratio as information at a time of recording a captured image, acquiring first photographic information for shooting at the first aspect ratio and second photographic information for shooting at a second aspect ratio; and controlling such that an image in a comprehensive area including the first aspect ratio and the second aspect ratio which is captured based on the first photographic information, the first photographic information, and the second photographic information are associated with each other and recorded on a recording medium.

  • Patent number: 7656435
    Abstract: By sensing an object without performing light projection with a light projection unit, a first image is acquired, and by sensing the object while performing light projection with the light projection unit, a second image is acquired. Based on the acquired first image and the second image, a pixel having a specific color in the first image is extracted.

  • Patent number: 7342610
    Abstract: In a method of controlling an image sensing apparatus, which has an image sensing device, a flash light used to illuminate an object with light, and a shutter switch, when an image sensing instruction is issued upon depression of the shutter button, an image is sensed using the flash. Then, a color temperature for processing the sensed image is calculated using at least color temperature information of the sensed image. The sensed image is processed based on the calculated color temperature.

  • Patent number: 6943835
    Abstract: An image pickup apparatus is disclosed to prevent recording of a degraded image by restricting setting of an electronic zoom function when a recording mode is set to a low-compression ratio mode or non-compression mode. The image pickup apparatus comprises a processing device for electronically enlarging an image picked up by an image pickup unit, a setting device for setting compressing operation for the image picked up by the image pickup unit, and a control device to restrict operation of the processing device in accordance with the compressing operation for the image which is set by the setting device. When a compression ratio equal to or less than a predetermined value is set by the recording mode setting unit or the non-compression mode is set, a system control circuit inhibits the electronic zoom function that tends to cause a deterioration in image quality from being turned on.

  • Publication number: 20040174458
    Abstract: The present invention provides an image reproduction apparatus and method including a recording medium that stores a plurality of image files having a file structure that contains a first image and a second image that is a low-resolution version of the first image, a display unit that displays an image according to the plurality of image file stores on the recording medium, and an operating unit operated by a user for fast forwarding images displayed on the display unit. While the operating unit is in a predetermined operating state, the second images in the plurality of image files are continuously fast forwarded. When the operating unit is released from the predetermined operating state, the display unit displays a first, high-resolution image corresponding to a second, low-resolution image displayed a predetermined number of images before the second image displayed when the operating unit is released from that predetermined operating state.

  • Publication number: 20020028076
    Abstract: It is an object of this invention to prevent recording of a degraded image by restricting setting of an electronic zoom function when a recording mode designed to prevent a deterioration in image quality is set to a low-compression ratio mode or non-compression mode. In order to achieve the above object, there is provided an image pickup apparatus comprising a processing device for electronically enlarging an image picked up by an image pickup unit, a setting device for setting compressing operation for the image picked up by the image pickup unit, and a control device for determining whether to restrict operation of the processing device in accordance with the compressing operation for the image which is set by the setting device.
