摘要:
The present invention is directed to obtaining an image having predetermined brightness, while making the degradation of the image as little as possible. A distance (an irradiation distance d) at which a predetermined amount of reflected light can be obtained is obtained from the guide number Gn of a strobe and the f-stop value F (the focal distance f of a zoom lens). When the strobe is used, it is judged whether or not a subject is positioned within the irradiation distance d. When the irradiation distance d of the strobe is shorter than the distance to the subject, that is, the subject is beyond the irradiation distance d of the strobe, an imaging signal is amplified than usual.

In a binary search, two storage units are prepared so that when the least significant bit of the search address is “0” and “1”, even and odd address banks respectively are used. The search object data is classified according to data belonging to the odd and even addresses in continuous addresses and allocated to these two storage units. Further, a search tree of the search address is constructed so that two data of object for a next search are stored in different storage units. Upon the binary search, addresses for the two storage units are set according to this search tree. Therefore, simultaneous readout of data is enabled, so that readout and comparison are carried out in parallel. Further, according to multiple division search of the invention, if 2 bits of the least significant bits of the search address are “00”, “01”, “10” and “11”, a search object data is stored in first through fourth banks respectively. A search tree of the search address is constructed so that four data of object for a next search are stored in different banks. Upon a search, an address for each bank is set according to the search tree so as to enable readout of data at the same time, thereby reducing time required for the search.
摘要:
An accessory unit is mounted on an electronic camera, and a printer connects to the electronic camera via a SCSI terminal of the accessory unit. An image signal is captured from a CCD in response to the releasing operation, and the image signal is analog-to-digital converted before being transferred to the accessory unit. The accessory unit converts the image signal into RGB data suitable for the printer, and outputs the RGB data to the printer so that the captured image can be simultaneously with the image-capturing. Moreover, during sequential image-capturing, captured image data is sequentially stored in an uncompressed state in a frame memory of the accessory unit. After sequential image-capturing is completed, the image data is transferred to the camera in an order in which it is stored, and compressed. Further, a background image is recorded in a memory card in advance, and an image is composed from the background image and a captured image (or a reproduced image) in the accessory unit. The composite image data is then transferred to the printer.

摘要:
A suitable image is obtained of a subject in which the difference in luminance between a bright area and a dark area is very large. The dark area is properly exposed and first image data is obtained. The bright area is properly exposed, and second image data is obtained. The first image data pertaining to the bright area is replaced with the second image data, thereby obtaining composite image data. This is accomplished using an array of photodiodes comprising two sets of photodiodes, one set of the photodiodes comprising filters, and the respective sets of photodiodes output signals to respectively different transfer paths for signal processing.
摘要:
An electronic still camera uses a charge coupled solid-state image pickup device and reads out pixel signals from photoelectric conversion elements by separating the photoelectric conversion elements into a number of fields. In a first embodiment, the elements are separated into k number of fields and an empty reading operation of the vertical and horizontal charge transfer paths are implemented without field shifting pixel signals from the elements to the transfer paths to thereby preserve the pixel signals in the elements. Accordingly, smear contents are removed and the influence of dark current is made uniform to prevent the occurrence of flicker. In a second embodiment, an empty reading operation of the vertical and horizontal charge transfer paths is implemented just after exposure. After the empty reading operation, normal field scanning and reading operation is restarted from the pixel signals corresponding to the field where the field shifting operation is stopped. Accordingly, smear contents are removed and dark current is made uniform.
