Abstract: A door pull (10) including a fixing portion (11) fixed on the door stopper stile (8A) of a shoji, an operating portion (12) fixed slidably in the opening direction of the shoji relative to this fixing portion (11), and a turning portion (13) supported by the fixing portion (11), a first of which is linked turnably with the operating portion (12), turning in conjunction with a slide of the operating portion (12), and a second end projects towards the jamb. According to this door pull (10), by sliding the operating portion (12), an abutment (132) representing the second end of the turning portion (13) abuts against the jamb and biases the shoji in the direction away from the jamb, and the opening operation of the shoji is assisted. Therefore, the door pull (10) having an opening assistance mechanism is constituted by a simple structure of having only the fixing portion (11), the operating portion (12) and the turning portion (13) and the number of component parts can be reduced thereby.

Abstract: An image processing technique for improving image resolution by increasing an effective number of pixels that represents a captured image. The technique involves obtaining a first exposure and at least a second exposure of an object. The image data of the second exposure differs from the image data of the first exposure in that a focal length for the second exposure differs from that for the first exposure. To the extent there exists a correlation, the image data of the second exposure is used for pixel data for each pixel of the image data of the first exposure requiring resolution improvement. When such correlation does not exist, pixel interpolation is performed using pixel data created by means of calculation for pixel interpolation positions.

Abstract: A digital camera which uses the resources of silver halide single lens reflex cameras to provide an angle of field equal to that of a silver halide single lens reflex camera without enlarging the size of the image sensing element, and which provides excellent holding characteristics because the camera body is not elongated in the backward direction. A taking lens for a silver halide single lens reflex camera is used as a taking lens 301. A digital camera provided with a reducing lens 302 disposed behind a taking lens in the direction of the optical axis of the taking lens and on the optical axis of the taking lens, and a CCD sensor 303 for photoelectrically converting an optical image transmitted through the taking lens and the reducing lens, and which is disposed at the composite focus point of the taking lens and the reducing lens. This construction ensures the field angle is identical to that of a silver halide single lens reflex camera even when a small size image sensing element is used.

In accordance with the pivotal movement of the mirror, a driver moves the image pick-up unit along the optical direction of the image taking lens.

The image pickup apparatus also has a first subtracter for calculating the difference between the outputs of the first-type pixels and the outputs of the second-type pixels on the first-type lines, and a second subtracter for calculating the difference between the outputs of the first-type pixels and the output of the third-type pixels on the second-type lines.

Abstract: A digital camera obtains a plurality of images by performing divided exposure of the CCD image sensor, and generates a shot image of the subject by composing the images. When divided exposure is performed, preset one mode is identified from among an image quality priority mode and a shooting speed priority mode. Then, by dividing the set exposure time at the time of shooting by the number of divisions defined by the identified mode, divided exposure control of the CCD image sensor is performed. The number of divisions in the image quality priority mode is larger than that in the shooting speed priority mode.

Abstract: Under exposure determination unit 212 determines whether or not there is under exposure during exposure set using a hand vibration time limit. When a suitable exposure time is longer than the hand vibration time limit, the exposure time is increased by increasing the gain set for the hand vibration time limit. When a flash is used, the distance the emitted light of the flash must reach is determined from the flash guide number and open aperture value, and a determination is made as to whether or not the light emitted by the flash will reach the photographic subject. Under exposure is determined when the distance to the photographic subject is longer than the distance attained by the light emitted from the flash, and the gain is adjusted in accordance therewith.

Abstract: An electronic still camera in which taken images are recorded onto a memory card has an LCD for image display, a RAM for image storage and a switch for image selection. Photographing is started before a direction to start recording is provided by the user. Photographing is continued even after the direction is provided and a predetermined number of images taken over a period spanning before and after the direction to start recording is provided are stored in the RAM. The images stored in the RAM are successively displayed on the LCD and the images which the user determines to be necessary and specifies by operating the switch are recorded onto the memory card.

Abstract: In a digital camera having a half mirror retractable out of the optical path and an optical viewfinder receiving light reflected from the half mirror, the sensitivity of an image-sensing device is set as specified by the user. When a relatively high sensitivity is specified, an image to be recorded is shot with the half mirror operated as a quick-return mirror, and, when a relatively low sensitivity is specified, an image to be recorded is shot with the half mirror kept in the optical path. A sensitivity that cannot be coped with simply by changing the position of the half mirror is set by adjusting, in conjunction therewith, the output gain of the image-sensing device.
