    摘要: A focus detection system for detecting a focus state of an object lens, includes an optical device for forming first and second light distributions corresponding to first and second images having light fluxes passing through the different parts of a pupila of the object lens. The positional relationship between the two light distributions varies in accordance with the focus state of the object lens. First and second sensors sense the first and second light distributions. A signal processor for processing output signals from the first and second sensors detect the focus state of the object lens in accordance with the positional relationships between the two light distributions. The signal processor processes the signals from the first and second sensors in accordance with a predetermined formula to obtain the positional relationship between the two images to determine a degree of coincidence of the two light distributions. The signal processing means provides an output signal in accordance with the degree of coincidence of the two light distributions.

    摘要: A focus detection system includes an object lens for focusing an image of an object, a refocusing optical system for refocusing a plurality of component image having parallax from the image of the image, a view field mask arranged between the object lens and the refocusing optical system and having a laterally extending aperture, and a sensing device having a photo-sensor array for sensing the component images. Focus detection error is prevented by determining a sense area of the photo-sensor array in accordance with a distortion created in an aperture image by the refocusing optical system.

    摘要: A recording apparatus records an image by scanning a first recording head relative to a recording medium of a particular type. The apparatus includes the first recording head, a pattern recording controller, a reader, a restoring device, a second recording head, a discriminator and a control unit. The pattern recording controller controls recording of a predetermined pattern with the first recording head at a predetermined timing either on the recording medium or on a pattern recording medium different from the recording medium. The reader reads the predetermined pattern and the restoring device performs a discharge restoring operation of the recording head. The discriminator discriminates a recording state of the first recording head, based on the predetermined pattern read by the reader. The control unit enables the second recording head to record the image to be recorded by the first recording head, in a case that after the discriminator discriminates the recording state as being poor and thereafter the discharge restoring operation performed by the restoring device and a pattern recording operation by the pattern recording controller have been executed a predetermined number of times, the discriminator has discriminated the recording state as being still poor.
