摘要： A zoom lens of this invention comprises in successive order from the object side a first group having a positive refractive power and fixed, a second group having a negative refracting power for effecting a variation of image magnification by moving on the optical axis, a third group having a positive power for effecting a light condensing action and fixed, and a fourth group moving on the optical axis so as to keep an image surface position to be changed in response to a move of the second group and a move of the object in a constant positional relation with the reference surface. Comparatively large air space is provided between the third and fourth groups of the zoom lens.

The camera controller is configured to calculate an evaluation value on the basis of the image data produced by the imaging element, and is configured to perform video autofocusing on the basis of the evaluation value. The camera controller controls the imaging element and the internal light source so that when the camera controller decides that the auxiliary light is needed, and the camera controller decides that the flash device mounted to the hot shoe has an external auxiliary light source arranged to emit near infrared light, the internal light source emits light during the video autofocusing and the image data is acquired.

摘要： In the image detector according to the present invention, a signal processing block generates a video signal by processing a pickup image signal corresponding to an image of an object which is picked up by an image pickup block and a motion detection block detects variations per unit time of luminance or a color of a portion or a whole of an image formed on the basis of the video signal as character variables of the image. A character analyzing block divides the video signal generated by the signal processing block into signals at durations each having the same character variable of the image detected by a motion detection block, and adds, to each of the divided video signals, an importance degree determined according to the character variables of the image and a duration of the signal, thereby making it possible to save memory capacities, accelerate retrieval of pickup images and enhance utilization efficiencies of transmission systems for lessening loads.

摘要： A zoom lens, having a camera shake correction function, that is capable of preventing degradation of chromatic aberration while correcting camera shake, and can be small, light-weight and power-saving, is provided. The zoom lens is composed of four groups of lenses having positive, negative, positive and positive refractive powers, arranged in that order from an object side to an image plane side, where a second lens group conducts zooming and a fourth lens group conducts focus adjustment. The second lens group is made of a concave meniscus lens, a concave lens, a double convex lens, and a concave lens, arranged in that order from the object side to the image plane side, and it includes also at least one aspheric surface. A third lens group includes a cemented lens having a cemented surface whose convex surface faces the object side, and can be shifted in a perpendicular direction with respect to an optical axis in order to correct image fluctuations during a camera shake.
