发明名称 Digital electronic still camera effecting analog-to-digital conversion after color balance adjustment and gradation correction
摘要 A digital electronic still camera is provided in which a video signal representing a still picture is stored in the form of digital data which includes an imaging unit having an imaging device with an array of photosensitive cells and a color filter having separated-color segments arranged thereon. An object scene is shot by use of the imaging device to produce a video signal representing the object scene. The camera includes a color balance adjusting circuit for adjusting a color balance of the video signal produced from the imaging device, a gradation correction circuit for correcting a gradation of the video signal having the color balance adjustment performed thereon, a signal converter for converting the video signal delivered from the gradation correcting circuit to produce a digital signal, and a controller for controlling the imaging unit, the color balance adjustment circuit, the gradation correcting circuit, and the signal converter. Thereby a shooting operation, a color balance adjustment, a gradation correction and a conversion of a video signal into a digital signal may be effected, and a control signal for causing a digital video signal to be stored may be produced.
